DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/017357
Kind Code:
A1
Abstract:
The present invention provides a display device which has a high aperture ratio. The present invention has a first pixel, a second pixel positioned adjacent to the first pixel, a first electrically conductive layer, a second electrically conductive layer, and an insulating layer. The first pixel has a first pixel electrode, a first EL layer on the first pixel electrode, and a common electrode on the first EL layer. The second pixel has a second pixel electrode, a second EL layer on the second pixel electrode, and a common electrode on the second EL layer. The first electrically conductive layer is arranged on the common electrode. The first insulating layer is positioned on the first electrically conductive layer. The second electrically conductive layer is arranged on the first insulating layer. The first electrically conductive layer and/or second electrically conductive layer overlap with a region sandwiched by the first EL layer and the second EL layer, and one side surface of the first EL layer and one side surface of the second EL layer are positioned facing each other.
