Abstract

A display apparatus includes a substrate, a pixel-defining film disposed on the substrate and that includes a first opening formed therein, a first organic light-emitting diode that includes a pixel electrode, an emission layer, and a counter electrode disposed in the first opening, a first light-blocking layer disposed on the pixel-defining film and that includes a second opening formed therein, where the second opening overlaps the first opening, a first color filter that overlaps the second opening of the first light-blocking layer, and a first high-refractive index layer that overlaps the first light-blocking layer and has a convex lens shape.

First claim

What is claimed is:

1 . A display apparatus, comprising:
a substrate; a pixel-defining film disposed on the substrate and comprising a first opening formed therein; a first organic light-emitting diode that includes a pixel electrode, an emission layer, and a counter electrode disposed in the first opening; a first light-blocking layer disposed on the pixel-defining film and that includes a second opening formed therein, wherein the second opening overlaps the first opening; a first color filter that overlaps the second opening; and a first high-refractive index layer that overlaps the first light-blocking layer and has a convex lens shape.

2 . The display apparatus of claim 1 , further comprising a first touch electrode disposed on the first organic light-emitting diode,
wherein the first light-blocking layer overlaps the first touch electrode.

3 . The display apparatus of claim 2 , wherein the first touch electrode comprises at least one of titanium (Ti), aluminum (Al), molybdenum (Mo), or copper (Cu).

4 . The display apparatus of claim 1 , further comprising an overcoat layer disposed on the first high-refractive index layer.

5 . The display apparatus of claim 4 , wherein a refractive index of the first high-refractive index layer is greater than a refractive index of the overcoat layer.

6 . The display apparatus of claim 1 , wherein a size of the second opening is greater than a size of the first opening.

7 . The display apparatus of claim 1 , wherein a length of the first high-refractive index layer in a first direction is greater than a length of the first light-blocking layer in the first direction.

8 . The display apparatus of claim 1 , further comprising a thin-film encapsulation layer disposed on the first organic light-emitting diode.

9 . The display apparatus of claim 8 , further comprising a touchscreen layer disposed on the thin-film encapsulation layer.

10 . The display apparatus of claim 1 , further comprising a pixel circuit disposed on the substrate and electrically connected to the first organic light-emitting diode.

11 . The display apparatus of claim 1 , further comprising a second light-blocking layer that overlaps at least a part of the first organic light-emitting diode.

12 . The display apparatus of claim 11 , further comprising a second high-refractive index layer that overlaps the second light-blocking layer and has a convex lens shape.

13 . The display apparatus of claim 11 , wherein a length of the second light-blocking layer in a first direction is less than a length of the first opening in the first direction.

14 . The display apparatus of claim 11 , further comprising a second touch electrode disposed in the second light-blocking layer.

15 . The display apparatus of claim 12 , wherein a length of the second high-refractive index layer in a first direction is greater than a length of the second light-blocking layer in the first direction.

16 . The display apparatus of claim 14 , wherein the second touch electrode comprises at least one of titanium (Ti), aluminum (Al), molybdenum (Mo), or copper (Cu).

17 . A display apparatus, comprising:
a first sub-pixel and a second sub-pixel disposed in a display area; a light-blocking layer that overlaps an emission area of the first sub-pixel and includes an opening portion; a first color filter layer that overlaps the emission area of the first sub-pixel; and a high-refractive index layer disposed on the first color filter layer and that overlaps the light-blocking layer and has a convex lens shape.

18 . The display apparatus of claim 17 , further comprising a first touch electrode,
wherein the first touch electrode does not overlap the emission area of the first sub-pixel and directly contacts the light-blocking layer.

19 . The display apparatus of claim 18 , further comprising a metal light-blocking portion,
wherein the metal light-blocking portion overlaps the emission area of the first sub-pixel and directly contacts the light-blocking layer.

20 . The display apparatus of claim 19 , wherein the first touch electrode transmits a touch signal, and the metal light-blocking portion is grounded.
