DISPLAY DEVICE

WIPO Patent Application WO/2023/089447

A1

The present invention provides a display device which is suppressed in crosstalk. This display device comprises: a first insulating layer that has a first region and a second region, the upper surface of which is positioned lower than the upper surface of the first region; a second insulating layer that has a region which overlaps with the first region; a light emitting device that has a region which overlaps with the first region, with the second insulating layer being interposed therebetween; a multilayer body that has a region which overlaps with the second region; and a third insulating layer that has a region which overlaps with the multilayer body. With respect to this display device, the second insulating layer has a projected part that overlaps with the second region; the light emitting device comprises at least a light emitting layer, a first upper electrode that is on the light emitting layer, and a second upper electrode that is on the first upper electrode; the second upper electrode has a region which overlaps with the third insulating layer; and the multilayer body has a same material as the light emitting layer.
