Abstract

A display device includes a display panel including: a first display region; a main display region; first light-emitting elements at the first display region; a connection part at the first display region, and connecting adjacent first light-emitting elements from among the first light-emitting elements to each other; and a light blocking pattern overlapping with the connection part in a plan view. The light blocking pattern includes: a first light blocking pattern spaced from the first light-emitting elements with a first gap between the first light blocking pattern and adjacent ones of the first light-emitting elements, the first light blocking pattern being located at the same layer as that at which at least a portion of each of the first light-emitting elements is located; and a second light blocking pattern under the first light blocking pattern, at least a portion of the second light blocking pattern overlapping with the first gap.

Claims (60)

1 . A display device comprising a display panel including a first display region, and a main display region surrounding at least a portion of the first display region, the display panel comprising:

a plurality of first light-emitting elements at the first display region;

a connection part at the first display region, and connecting adjacent first light-emitting elements from among the plurality of first light-emitting elements to each other; and

a light blocking pattern overlapping with the connection part in a plan view,

wherein the light blocking pattern comprises:

a first light blocking pattern spaced from the plurality of first light-emitting elements with a first gap between the first light blocking pattern and adjacent ones of the first light-emitting elements, the first light blocking pattern being located at a same layer as that at which at least a portion of each of the plurality of first light-emitting elements is located; and

a second light blocking pattern under the first light blocking pattern, at least a portion of the second light blocking pattern overlapping with the first gap, and

wherein the first light blocking pattern is located between the adjacent ones of the first light-emitting elements in a plan view, and the connection part integrally extends over the first light blocking pattern and directly contacts first upper electrodes of the adjacent ones of the first light-emitting elements to electrically and integrally connect the first upper electrodes of the adjacent ones of the first light-emitting elements to each other.

2 . The display device of claim 1 , wherein each of the plurality of first light-emitting elements comprises:

a first lower electrode;

a first light-emitting layer on the first lower electrode; and

the first upper electrode on the first light-emitting layer, and

wherein the first light blocking pattern is located at a same layer at which the first lower electrode is located.

3 . The display device of claim 2 , wherein the first light blocking pattern and the first lower electrode comprise a same material as each other.

4 . The display device of claim 2 , wherein the connection part and the first upper electrode comprise a same material as each other.

5 . The display device of claim 2 , wherein a plurality of electrode openings are defined in the first upper electrode.

6 . The display device of claim 2 , wherein the first display region comprises:

an element region at which the plurality of first light-emitting elements are located;

a wiring region at which the connection part is located; and

a transmission region adjacent to the element region and the wiring region, and

wherein each of the first lower electrode and the first upper electrode overlaps with the element region, and does not overlap with the transmission region.

7 . The display device of claim 1 , wherein the display panel comprises:

a base layer configured to provide a base surface on which the plurality of first light-emitting elements are located; and

a circuit layer between the base layer and the plurality of first light-emitting elements,

wherein the circuit layer comprises a plurality of insulating layers, and

wherein the second light blocking pattern is located on the base layer or on any one layer from among the plurality of insulating layers.

8 . The display device of claim 1 , wherein:

the second light blocking pattern comprises a first sub blocking pattern and a second sub blocking pattern;

a second gap overlapping with a portion of the connection part is defined between the first sub blocking pattern and the second sub blocking pattern; and

the first light blocking pattern overlaps with the second gap.

9 . The display device of claim 1 , wherein the display panel further includes a second display region adjacent to the first display region, and

wherein the display panel further comprises:

a second light-emitting element at the second display region;

a first pixel circuit at the second display region, and configured to drive a corresponding first light-emitting element from among the plurality of first light-emitting elements; and

a second pixel circuit at the second display region, and configured to drive the second light-emitting element.

10 . The display device of claim 9 , wherein the display panel further comprises:

a third light-emitting element at the main display region; and

a third pixel circuit at the main display region, and configured to drive the third light-emitting element, and

wherein a transmittance of the first display region is higher than a transmittance of the second display region and a transmittance of the main display region.

11 . The display device of claim 1 , wherein a thickness of the second light blocking pattern is about 100 nm to about 500 nm.

12 . The display device of claim 1 , further comprising an electronic module located under the display panel, and overlapping with the first display region in a plan view.

13 . The display device of claim 1 , wherein the light blocking pattern comprises a metal material, and the metal material is configured to absorb or reflect an incident infrared laser.

14 . The display device of claim 1 , wherein a portion of the second light blocking pattern overlaps with the first light blocking pattern in a plan view.

15 . A display device comprising:

a base layer;

a circuit layer on the base layer;

a plurality of first light-emitting elements on the circuit layer;

a connection part configured to connect adjacent first light-emitting elements from among the plurality of first light-emitting elements to each other; and

a light blocking pattern overlapping with the connection part in a plan view,

wherein each of the plurality of first light-emitting elements comprises:

a first lower electrode;

a first light-emitting layer on the first lower electrode; and

a first upper electrode on the first light-emitting layer,

wherein the circuit layer comprises a plurality of insulating layers,

wherein the light blocking pattern comprises:

a first light blocking pattern spaced from the first lower electrode, and located at a same layer as that of the first lower electrode; and

a second light blocking pattern on the base layer or on any one layer from among the plurality of insulating layers, at least a portion of the second light blocking pattern overlapping with a gap defining the space between the first lower electrode and the first light blocking pattern, and
