Abstract

The present disclosure relates to an organic light emitting diode display device including: a substrate having an emitting area and a non-emitting area; an insulating layer on the substrate, the insulating layer including a plurality of convex portions, a plurality of connecting portions and at least one wall in the emitting area, a height of the at least one wall is greater than a height of the plurality of convex portions; a first electrode on the substrate; an emitting layer on the first electrode; and a second electrode on the emitting layer, the first electrode, the emitting layer and the second electrode constituting a light emitting diode.

First claim

What is claimed is:

1 . An organic light emitting diode display device, comprising:
a substrate having an emitting area and a non-emitting area; an insulating layer over the substrate, the insulating layer including a plurality of convex portions; a first electrode over the insulating layer; an emitting layer over the first electrode; and a second electrode over the emitting layer, wherein a portion of the plurality of convex portions extends from the emitting area to the non-emitting area, and wherein the first electrode is disposed over a slanting surface of the plurality of convex portions in the non-emitting area.

2 . The device of claim 1 , further comprising:
a bank layer between the first electrode and the emitting layer in the non-emitting area; and a color filter layer over the second electrode in the emitting area.

3 . The device of claim 2 , wherein an edge of the color filter layer extends beyond an edge of the plurality of convex portions toward the non-emitting area.

4 . The device of claim 2 , wherein an edge of the plurality of convex portions, an edge of the bank layer and an edge of the color filter layer overlap each other in the non-emitting area.

5 . The device of claim 2 , wherein the bank layer overlays an edge of the plurality of convex portions.

6 . The device of claim 2 , wherein a boundary between the emitting area and the non-emitting area overlaps a portion of the plurality of convex portions.

7 . The device of claim 1 , wherein the plurality of convex portions are arranged in a line along a first direction and staggered along a second direction.

8 . The device of claim 1 , wherein the insulating layer further includes at least one wall, and
wherein the first electrode is disposed in the emitting area to expose a top portion of the at least one wall.

9 . The device of claim 8 , wherein portions of the first electrode around the at least one wall are electrically connected to each other in the emitting area.

10 . The device of claim 1 , wherein the insulating layer further includes at least one wall,
wherein the first electrode is disposed in the emitting area to expose a side portion of the at least one wall, and wherein the emitting layer and the second electrode are disposed on the first electrode and the at least one wall.

11 . The device of claim 10 , wherein portions of the first electrode around the at least one wall are electrically connected to each other in the emitting area.

12 . The device of claim 1 , wherein the insulating layer further includes at least one wall, and
wherein the first electrode is disposed in the emitting area to cover a top portion of the at least one wall.

13 . The device of claim 12 , wherein portions of the first electrode around the at least one wall are electrically connected to each other in the emitting area.

14 . The device of claim 12 , further comprising a light shielding pattern disposed over the first electrode over the at least one wall.
