Abstract

A display device includes first and second areas. The second area includes a display panel including a plurality of light emitting areas respectively overlapping element areas and a non-light-emitting area at least partially surrounding the light emitting areas such that at least a portion of the non-light-emitting area overlaps a peripheral area. A lower cover layer is disposed on the display panel, overlapping the first area and the second area, and including cover patterns respectively overlapping the light emitting areas of the second area. A light blocking pattern is disposed on the lower cover layer overlapping the second area. The light blocking pattern covers a portion of an upper surface of each of the cover patterns.

Claims (20)

1 . A display device, comprising:

a display panel comprising first and second areas each comprising element areas in which light emitting elements are disposed and a peripheral area, the first area comprising a plurality of light emitting areas, the second area comprising a plurality of light emitting areas respectively overlapping the element areas and a non-light-emitting area at least partially surrounding the light emitting areas such that at least a portion of the non-light-emitting area overlaps the peripheral area;

a lower cover layer disposed on the display panel, overlapping the first area and the second area, and comprising cover patterns respectively overlapping the light emitting areas of the second area; and

a light blocking pattern overlapping the non-light-emitting area and disposed on the lower cover layer overlapping the second area, wherein the light blocking pattern covers a portion of an upper surface of each of the cover patterns,

wherein the light emitting areas of the second area are smaller than the light emitting areas of the first area.

2 . The display device of claim 1 , wherein the light blocking pattern has a width that varies along a thickness direction of the display panel.

3 . The display device of claim 1 , wherein an upper surface of the light blocking pattern has a concave shape that is concaved in a direction toward the display panel.

4 . The display device of claim 1 , further comprising an input sensor disposed between the display panel and the lower cover layer, the input sensor comprising sensing electrodes and sensing insulating layers, wherein the sensing electrodes overlap the peripheral area.

5 . The display device of claim 4 , wherein the light blocking pattern is in contact with an uppermost sensing insulating layer, among the sensing insulating layers, that is closest to the lower cover layer.

6 . The display device of claim 4 , wherein each of the sensing electrodes has a width that is smaller than a maximum width of the light blocking pattern.

7 . The display device of claim 4 , wherein at least a portion of the light blocking pattern is disposed in the lower cover layer, and the light blocking pattern is spaced apart from an uppermost sensing insulating layer, among the sensing insulating layers, closest to the lower cover layer.

8 . The display device of claim 4 , further comprising an additional cover layer disposed between an uppermost sensing insulating layer closest to the lower cover layer, among the sensing insulating layers, and the lower cover layer, wherein the light blocking pattern is in contact with the additional cover layer.

9 . The display device of claim 4 , wherein the sensing electrodes do not overlap a portion between the light emitting areas adjacent to each other among the light emitting areas of the second area.

10 . The display device of claim 1 , wherein the light blocking pattern has a grid shape in which light blocking openings overlap the light emitting areas of the second area, and each of the cover patterns overlaps a corresponding light blocking opening among the light blocking openings.

11 . The display device of claim 1 , wherein the light emitting areas of the second area have a same size as each other.

12 . The display device of claim 1 , wherein each of the light emitting elements comprises a first electrode, a second electrode, and a light emitting layer disposed between the first electrode and the second electrode, and the display panel comprises a first pixel definition layer through which openings expose at least a portion of each of the first electrodes.

13 . The display device of claim 12 , wherein the display panel of the second area comprises a second pixel definition layer disposed on the first electrodes exposed through the openings and overlapping the non-light-emitting area.

14 . The display device of claim 13 , wherein the light emitting areas of the first area respectively overlap the element areas and a non-light-emitting area surrounding the light emitting areas such that at least a portion of the non-light-emitting area overlaps the peripheral area.

15 . The display device of claim 14 , wherein the light emitting areas of the first area have a same size as each other.

16 . The display device of claim 1 , wherein the display panel activates the light emitting elements of the first area and the light emitting elements of the second area in a first operation mode, deactivates the light emitting elements of the first area in a second operation mode, and activates the light emitting elements of the second area in the second operation mode.
