Abstract

A display device includes, on a substrate, light emitting elements each formed by sequentially stacking a first electrode layer, an organic layer including a light emission layer, and a second electrode layer and arranged in first and second directions which cross each other, a drive circuit including drive elements that drive light emitting elements, and a wiring extending in the first direction, and an insulating layer disposed in a gap region sandwiched by the light emitting elements neighboring in the second direction and having a recess or a projection. The wiring is disposed in an overlap region overlapping with the recess or the projection in the insulating layer in a thickness direction, in the gap region, and the second electrode layers in the light emitting elements neighboring in the second direction are separated from each other by the recess or the projection in the insulating layer.

Claims (14)

1. A display device comprising, on a substrate:

a plurality of light emitting elements each formed by sequentially stacking a first electrode layer, an organic layer including a light emission layer, and a second electrode layer and arranged in first and second directions which cross each other;

a drive circuit including a plurality of drive elements that drive the plurality of light emitting elements, and a wiring extending in the first direction; and

an insulating layer disposed in a gap region sandwiched by the light emitting elements neighboring in the second direction and having a recess or a projection,

wherein the wiring is disposed in an overlap region overlapping with the recess or the projection in the insulating layer in a thickness direction, in the gap region, and

the second electrode layers in the light emitting elements neighboring in the second direction are separated from each other by the recess or the projection in the insulating layer.

2. The display device according to claim 1 , wherein

the second electrode layer extends in the first direction, and

the second electrode layer is provided commonly to the plurality of light emitting elements arranged in the first direction.

3. The display device according to claim 1 , wherein

the recess or the projection in the insulating layer has a sectional shape including two surfaces crossing each other at an acute angle.

4. The display device according to claim 1 , further comprising:

an auxiliary wiring which is electrically connected to the second electrode layer; and

wherein the auxiliary wiring is provided in a region other than the overlap region, in the gap region.
