Abstract

A display apparatus includes a substrate including a component area and a main display area, the component area including sub display areas and transmission areas, main pixel electrodes disposed in the main display area and spaced apart from each other, sub pixel electrodes disposed in the sub display areas and spaced apart from each other, a pixel definition layer covering an edge of each of the main pixel electrodes and an edge of each of the sub pixel electrodes and including transmission holes in areas corresponding to the transmission areas, main spacers disposed on the pixel definition layer in the main display area, and sub spacers disposed on the pixel definition layer in the component area, wherein a number of the sub spacers per unit area is equal to a number of the main spacers per unit area in a plan view.

Claims (35)

1. A display apparatus comprising:

a substrate including a component area and a main display area disposed only outside the component area, the component area including sub display areas and transmission areas, and the main display area at least partially surrounding the component area;

main pixel electrodes disposed in the main display area and spaced apart from each other;

sub pixel electrodes disposed in the sub display areas and spaced apart from each other, the transmission areas being disposed between the sub pixel electrodes in the component area;

a pixel definition layer including openings in areas corresponding to the main pixel electrodes and the sub pixel electrodes, covering an edge of each of the main pixel electrodes and an edge of each of the sub pixel electrodes, and including transmission holes in areas corresponding to the transmission areas;

main spacers disposed on the pixel definition layer in the main display area; and

sub spacers disposed on the pixel definition layer in the component area,

wherein a number of the sub spacers per unit area is equal to a number of the main spacers per unit area in a plan view.

2. The display apparatus of claim 1 , wherein an area of each of the main spacers is equal to an area of each of the sub spacers in the plan view.

3. The display apparatus of claim 1 , wherein a shape of an area of each of the main spacers is same as a shape of an area of each of the sub spacers in a plan view.

4. The display apparatus of claim 1 , wherein the main spacers include first main spacers arranged at a certain interval from one another and second main spacers arranged at a certain interval from one another, and the first main spacers and the second main spacers are in a one-to-one correspondence to each other.

5. The display apparatus of claim 4 , wherein a distance between the first main spacers is equal to a distance between the second main spacers.

6. The display apparatus of claim 4 , wherein each of the first main spacers is disposed adjacent to a corresponding one of the second main spacers.

7. The display apparatus of claim 6 , wherein the sub spacers include first sub spacers arranged at a certain interval from one another and second sub spacers arranged at a certain interval from one another, and the first sub spacers and the second sub spacers are in a one-to-one correspondence to each other.

8. The display apparatus of claim 7 , wherein a distance between the first sub spacers is equal to a distance between the second sub spacers.

9. The display apparatus of claim 7 , wherein a distance between each of the first sub spacers and each of the second sub spacers is uniform.

10. The display apparatus of claim 7 , wherein the first sub spacers in the sub display area are disposed in areas corresponding to the first main spacers in the main display area.

11. The display apparatus of claim 7 , wherein the transmission holes of the pixel definition layer in the sub display area are disposed in areas corresponding to the second main spacers in the main display area.

12. The display apparatus of claim 7 , wherein the second main spacers in the main display area are disposed in areas corresponding to some of the transmission holes of the pixel definition layer in the sub display area.

13. The display apparatus of claim 1 , further comprising an antireflection layer disposed over the main pixel electrodes and the sub pixel electrodes and including a light blocking layer and color filters,

wherein the light blocking layer includes openings corresponding to the transmission holes of the pixel definition layer.

14. The display apparatus of claim 1 , wherein the pixel definition layer includes a light-blocking insulating material.

15. A display apparatus comprising:

a substrate including a component area and a main display area disposed only outside the component area, the component area including sub display areas and transmission areas, and the main display area at least partially surrounding the component area;

main pixel electrodes disposed in the main display area and spaced apart from each other;

sub pixel electrodes disposed in the sub display areas and spaced apart from each other, the transmission areas being disposed between the sub pixel electrodes in the component area;

a pixel definition layer including openings in areas corresponding to the main pixel electrodes and the sub pixel electrodes, covering an edge of each of the main pixel electrodes and an edge of each of the sub pixel electrodes, and including transmission holes corresponding to the transmission areas;

main spacers disposed on the pixel definition layer in the main display area; and

sub spacers disposed on the pixel definition layer in the component area,

wherein an area occupied by the sub spacers per unit area in the sub display area is equal to an area occupied by the main spacers per unit area in the main display area in a plan view.

16. The display apparatus of claim 15 , wherein the main spacers include first main spacers arranged at a certain interval from one another and second main spacers arranged at a certain interval from one another, and the first main spacers and the second main spacers are in a one-to-one correspondence to each other.

17. The display apparatus of claim 16 , wherein each of the first main spacers is disposed adjacent to a corresponding one of the second main spacers.

18. The display apparatus of claim 17 , wherein the sub spacers include first sub spacers arranged at a certain interval from each other and second sub spacers arranged at a certain interval from each other, and the first sub spacers and the second sub spacers are in a one-to-one correspondence to each other.

19. The display apparatus of claim 18 , wherein the first main spacers in the main display area are disposed in areas corresponding to the first sub spacers in the sub display area.

20. The display apparatus of claim 18 , wherein the second main spacers in the main display area are disposed in areas corresponding to some of the transmission holes of the pixel definition layer in the sub display area.
