Abstract

A display apparatus includes a substrate including a display area and a sensor area, the sensor area including an auxiliary display area and a transmitting area, first display elements arranged over the display area, second display elements arranged over the auxiliary display area, transmitting units arranged in the transmitting area and configured to transmit at least a portion of light incident on the transmitting units, and an optical layer including a mesh pattern covering at least the second display elements.

First claim

What is claimed is:

1. A display panel comprising:
a substrate including a main display area and a sensor area, the sensor area including an auxiliary display area and a transmitting area;
a plurality of first display elements arranged over the main display area;
a plurality of second display elements arranged over the auxiliary display area; and
an inorganic layer including a plurality of grooves overlapping with the plurality of second display elements,
wherein the plurality of grooves are recessed from an upper surface of the inorganic layer, and
wherein the plurality of grooves do not overlap the main display area and the transmitting area.

2. The display panel of claim 1 , wherein a number of the plurality of grooves overlapping with a light emitting region of one of the plurality of second display elements is at least two.

3. The display panel of claim 1 , wherein the plurality of grooves include a first group of grooves extending in a first direction and a second group of grooves extending in a second direction different from the first direction.

4. The display panel of claim 1 , wherein the plurality of grooves are arranged in a mesh pattern.

5. The display panel of claim 1 , further comprising a plurality of transmitting units arranged in the transmitting area and configured to transmit at least a portion of light incident on the transmitting area,
wherein the plurality of second display elements are grouped into a plurality of pixel units, and
wherein each of the plurality of pixel units and each of the plurality of transmitting units are alternately arranged.

6. The display panel of claim 1 ,
wherein each of the plurality of first display elements and the plurality of second display elements comprises:
a pixel electrode electrically connected to a thin film transistor;
a light emission layer on the pixel electrode; and
an opposite electrode on the light emission layer.

7. The display panel of claim 6 , the inorganic layer is disposed farther from the substrate than the light emission layer.

8. The display panel of claim 1 , further comprising:
a thin film transistor disposed between the substrate and the plurality of second display elements; and
a planarization layer covering the thin film transistor,
wherein the planarization layer include a transmitting opening corresponding to the transmitting area.

9. The display panel of claim 1 ,
wherein the inorganic layer extends to the main display area, and
wherein the upper surface of the inorganic layer at the main display area is flat.

10. The display panel of claim 1 , wherein the inorganic layer extends to the transmitting area, the upper surface of the inorganic layer at the main display area is flat.

11. A display apparatus comprising:
a display panel including a main display area and a sensor area, the sensor area including an auxiliary display area and a transmitting area; and
a component disposed under the sensor area of the display panel,
wherein the display panel comprising:
a substrate;
a plurality of first display elements arranged over the main display area;
a plurality of second display elements arranged over the auxiliary display area; and
an inorganic layer including a plurality of grooves overlapping with the plurality of second display elements,
wherein the plurality of grooves are recess from an upper surface of the inorganic layer, and
wherein the plurality of grooves do not overlap the main display area and the transmitting area.

12. The display apparatus of claim 11 , wherein a number of the plurality of grooves overlapping with a light emitting region of one of the plurality of second display elements is at least two.

13. The display apparatus of claim 11 , wherein the plurality of grooves include a first group of grooves extending in a first direction and a second group of grooves extending in a second direction different from the first direction.

14. The display apparatus of claim 11 , wherein the plurality of grooves are arranged in a mesh pattern.

15. The display apparatus of claim 11 , further comprising a plurality of transmitting units arranged in the transmitting area and configured to transmit at least a portion of light incident on the transmitting area,
wherein the plurality of second display elements are grouped into a plurality of pixel units, and
wherein each of the plurality of pixel units and each of the plurality of transmitting units are alternately arranged.

16. The display apparatus of claim 11 ,
wherein each of the plurality of first display elements and the plurality of second display elements comprises:
a pixel electrode electrically connected to a thin film transistor;
a light emission layer on the pixel electrode; and
an opposite electrode on the light emission layer.

17. The display apparatus of claim 16 , the inorganic layer is disposed farther from the substrate than the light emission layer.

18. The display apparatus of claim 11 , further comprising:
a thin film transistor disposed between the substrate and the plurality of second display elements; and
a planarization layer covering the thin film transistor,
wherein the planarization layer include a transmitting opening corresponding to the transmitting area.

19. The display apparatus of claim 11 , wherein the component is overlapped with the auxiliary display area and the transmitting area.

20. The display apparatus of claim 19 , wherein the component is a sensor using light.
