Abstract

A display apparatus includes: an overcoat layer; a first color filter layer, a second color filter layer, and a third color filter layer arranged on the overcoat layer; a first planarization layer arranged on the first color filter layer, the second color filter layer, and the third color filter layer; a second planarization layer arranged on the first planarization layer and defining a first through-hole, a second through-hole, and a third through-hole therein; a first quantum dot layer in the first through-hole; and a second quantum dot layer in the second through-hole.

Claims (26)

1 . A display apparatus comprising:

an overcoat layer;

a first planarization layer arranged on the overcoat layer;

a first color filter layer, a second color filter layer, and a third color filter layer, arranged disposed between the overcoat layer and the first planarization layer;

the first planarization layer arranged on the first color filter layer, the second color filter layer, and the third color filter layer;

a second planarization layer arranged on the first planarization layer and defining a first through-hole, a second through-hole, and a third through-hole therein;

a first quantum dot layer located in the first through-hole; and

a second quantum dot layer located in the second through-hole.

2 . The display apparatus of claim 1 , further comprising a light-transmitting layer located in the third through-hole.

3 . The display apparatus of claim 2 , wherein the first quantum dot layer at least partially overlaps the first color filter layer, the second quantum dot layer at least partially overlaps the second color filter layer, and the light-transmitting layer at least partially overlaps the third color filter layer in a plan view.

4 . The display apparatus of claim 2 , further comprising a light-emitting device arranged on the second planarization layer and including a light-emitting layer.

5 . The display apparatus of claim 4 , wherein the light-emitting device further comprises:

a pixel electrode; and

an opposite electrode corresponding to the pixel electrode,

wherein the light-emitting layer is arranged on the pixel electrode to be interposed between the pixel electrode and the opposite electrode.

6 . The display apparatus of claim 5 , wherein the pixel electrode is arranged directly on the first quantum dot layer.

7 . The display apparatus of claim 5 , further comprising a protective layer between the pixel electrode and the first quantum dot layer.

8 . The display apparatus of claim 5 , wherein the first quantum dot layer is between the first color filter layer and the light-emitting device.

9 . The display apparatus of claim 8 , further comprising a transistor between the first color filter layer and the first quantum dot layer.

10 . The display apparatus of claim 9 , wherein the transistor does not overlap the first color filter layer in a plan view.

11 . The display apparatus of claim 9 , further comprising a connection electrode on the transistor,

wherein the connection electrode electrically connects the transistor and the light-emitting device to each other.

12 . The display apparatus of claim 11 , further comprising a light-shielding electrode on the transistor.

13 . The display apparatus of claim 1 , wherein the second planarization layer has a maximum thickness of about 10 micrometers (μm) to about 15 μm.

14 . The display apparatus of claim 13 , wherein the first planarization layer has a maximum thickness of about 8 μm to about 13 μm.

15 . The display apparatus of claim 1 , wherein a bottom surface of each of the first through-hole, the second through-hole, and the third through-hole is convex in a direction toward the overcoat layer.
