摘要： A light emitting display device includes a substrate, a transistor, a first insulating layer, a second insulating layer, a pixel electrode, a conductive member, a third insulating layer, and a light emitting material layer. The transistor overlaps the substrate. The first insulating layer overlaps the transistor. The second insulating layer overlaps the first insulating layer. The pixel electrode directly contacts the second insulating layer and is electrically connected to the transistor. The conductive member directly contacts at least one of the first insulating layer and the second insulating layer. The third insulating layer overlaps the second insulating layer, includes a hole, and includes an opening. The hole exposes the pixel electrode. The opening exposes the conductive member. The light emitting material layer overlaps the pixel electrode inside the hole, overlaps the third insulating layer, and has a discontinuity inside the opening.
