Abstract

A display panel includes: a first area, a second area, and a third area, a resolution of the second area being less than a resolution of the first area; a substrate; a first pixel electrode at the first area on the substrate; a first pixel circuit at the first area on the substrate, the first pixel circuit being connected to the first pixel electrode; a second pixel electrode at the second area on the substrate; a second pixel circuit at the third area on the substrate, the second pixel circuit being connected to the second pixel electrode; and an opaque layer at the second area between the substrate and the second pixel electrode, the opaque layer including an insulating pattern overlapping with the second pixel electrode.

First claim

What is claimed is:

1. A display panel comprising:
a first area, a second area, and a third area, a resolution of the second area being less than a resolution of the first area;
a substrate;
a first pixel electrode at the first area on the substrate;
a first pixel circuit at the first area on the substrate, the first pixel circuit being connected to the first pixel electrode;
a second pixel electrode at the second area on the substrate;
a second pixel circuit at the third area on the substrate, the second pixel circuit being connected to the second pixel electrode; and
an opaque layer at the second area between the substrate and the second pixel electrode, the opaque layer comprising an insulating pattern overlapping with the second pixel electrode.

2. The display panel of claim 1 , further comprising:
a first organic insulating layer between the substrate and the second pixel electrode at the second area; and
a second organic insulating layer on the first organic insulating layer.

3. The display panel of claim 2 , wherein the opaque layer is between the second organic insulating layer and the second pixel electrode.

4. The display panel of claim 3 , wherein an upper surface of the opaque layer contacts the second pixel electrode, and
a lower surface of the opaque layer contacts the second organic insulating layer.

5. The display panel of claim 3 , wherein the second organic insulating layer includes a recess corresponding to the second pixel electrode, and
the opaque layer is in the recess of the second organic insulating layer.

6. The display panel of claim 2 , wherein the opaque layer is between the first organic insulating layer and the second organic insulating layer.

7. The display panel of claim 6 , wherein the first organic insulating layer includes a recess corresponding to the second pixel electrode, and
the opaque layer is in the recess of the first organic insulating layer.

8. The display panel of claim 2 , wherein a hole at a location corresponding to the second pixel electrode penetrates through the first organic insulating layer, and
the opaque layer is in the hole of the first organic insulating layer.

9. The display panel of claim 2 , further comprising a first connecting line between the first organic insulating layer and the second organic insulating layer at the second area, the first connecting line connecting the second pixel electrode to the second pixel circuit.

10. The display panel of claim 9 , further comprising a second connecting line at the third area, the second connecting line connecting the first connecting line to the second pixel circuit.

11. The display panel of claim 2 , further comprising a first connecting line between the substrate and the first organic insulating layer at the second area, the first connecting line connecting the second pixel electrode to the second pixel circuit.

12. The display panel of claim 11 , further comprising a second connecting line at the third area, the second connecting line connecting the first connecting line to the second pixel circuit.

13. The display panel of claim 1 , further comprising:
a first organic insulating layer covering the first pixel circuit at the first area and the second pixel circuit at the third area, the first organic insulating layer including a hole corresponding to the second area; and
a second organic insulating layer on the first organic insulating layer at the first area and the third area, the second organic insulating layer filling the hole of the first organic insulating layer at the second area between the substrate and the second pixel electrode.

14. The display panel of claim 13 , wherein the opaque layer is between the substrate and the second organic insulating layer at the second area.

15. The display panel of claim 14 , further comprising a first connecting line between the substrate and the second organic insulating layer at the second area, the first connecting line connecting the second pixel electrode to the second pixel circuit,
wherein the opaque layer at least partially covers the first connecting line.

16. The display panel of claim 15 , further comprising a second connecting line at the third area, the second connecting line connecting the first connecting line to the second pixel circuit.
