Abstract:
1. A display device comprising: a thin film transistor formed over a substrate, wherein the thin film transistor comprises a semiconductor film and a gate electrode with a gate insulating film interposed therebetween; a barrier layer formed over the gate electrode, wherein the barrier layer is a silicon nitride film; an insulating layer formed over the barrier layer; an electrode formed over the insulating layer, wherein the electrode is electrically connected to the semiconductor film; a planarization layer formed over the insulating layer, wherein the planarization layer covers a portion of the electrode; a pixel electrode formed over the planarization layer, wherein the pixel electrode is electrically connected to the electrode; a resin film formed over the planarization layer, wherein the resin film covers a portion of the pixel electrode; and a light emitting member formed over the pixel electrode; and a passivation film formed over the light emitting member, wherein the passivation film is a silicon nitride film, wherein the planarization layer comprises a first opening, wherein an edge portion of the planarization layer is rounded, wherein the edge portion of the planarization layer is formed at the first opening, wherein the pixel electrode is electrically connected to the electrode through the first opening, wherein the resin film comprises a second opening, wherein an edge portion of the resin film is rounded, wherein the edge portion of the resin film is formed at the second opening, wherein the resin film is provided in the first opening, and wherein a bottom of the first opening and a bottom of the second opening do not overlap with each other.
