Abstract

According to one embodiment, a display device includes a base, a first insulating layer arranged on the base, a first electrode arranged on the first insulating layer overlapping with a pixel in a display area, a second insulating layer arranged on the first insulating layer and including an aperture overlapping with the first electrode, a first spacer partially arranged on the second insulating layer overlapping with the display area, a partition arranged on the second insulating layer and the first spacer, an organic layer in contact with the first electrode, a second electrode arranged on the organic layer, a second spacer partially arranged on the second insulating layer overlapping with a surrounding area, and a support member arranged on the second spacer.

Claims (24)

1 . A display device comprising:

a base;

a first insulating layer arranged on the base;

a first electrode arranged on the first insulating layer overlapping with a pixel included in a display area;

a second insulating layer arranged on the first insulating layer and including an aperture overlapping with the first electrode;

a first spacer partially arranged on the second insulating layer overlapping with the display area;

a partition arranged on the second insulating layer and the first spacer so as to separate the pixel;

an organic layer in contact with the first electrode through the aperture;

a second electrode arranged on the organic layer;

a second spacer partially arranged on the second insulating layer overlapping with a surrounding area outside the display area; and

a support member arranged on the second spacer and corresponding to the partition.

2 . The display device of claim 1 , wherein

a height of the second spacer and the support member is substantially the same as a height of the first spacer and the partition.

3 . The display device of claim 1 , wherein

the first spacers are arranged at regular intervals on the second insulating layer overlapping with the display area, and

the second spacers are arranged at regular intervals on the second insulating layer overlapping with the surrounding area.

4 . The display device of claim 3 , wherein

the intervals at which the second spacers are arranged on the second insulating layer are substantially the same to the intervals at which the first spacers are arranged on the second insulating layer.

5 . The display device of claim 1 , wherein

the first spacer and the second spacer are formed of the same material as the second insulating layer.

6 . The display device of claim 1 , wherein

the partition has a shape in which a width of an upper portion is larger than a width of a lower portion.

7 . The display device of claim 1 , wherein

the second electrode overlapping with a first pixel is connected to the second electrode overlapping with a second pixel adjacent to the first pixel via an auxiliary wire arranged on between the second insulating layer or the first spacer and the partition.
