Abstract:
An organic EL display device includes a thin film transistor; a first insulating layer covering the thin film transistor; a first conductive layer on the first insulating layer; a second insulating layer on the first conductive layer; a second conductive layer on the second insulating layer; a pixel capacitor formed of the first conductive layer, the second insulating layer and the second conductive layer; a third insulating layer provided on the second conductive layer and including an opening in a region overlapping a part of the second conductive layer as seen in a plan view; and an organic layer covering the opening of the third insulating layer and including a light emitting layer. The first insulating layer includes a first groove in a region overlapping the third insulating layer as seen in a plan view, and a part of the pixel capacitor is located inside the first groove.
