Patent ID: 7671369

Claim:
A semiconductor display device comprising: a pixel portion over a substrate; and a semiconductor circuit generating a signal for displaying an image on the pixel portion over the substrate, the semiconductor circuit having a capacitor, wherein each of the pixel portion and the semiconductor circuit comprises a thin film transistor, each thin film transistor having an active layer and a gate electrode adjacent to the active layer with a gate insulating film interposed therebetween; wherein a first inorganic insulating film covers each thin film transistor, wherein an organic resin film is formed in contact with the first inorganic insulating film, wherein the organic resin film has a first opening part and a second opening part, wherein a second inorganic insulating film covers the organic resin film, wherein the first and second inorganic insulating films are in contact with each other in the first opening part and the second opening part, wherein a contact hole is formed in each gate insulating film and the first and second inorganic insulating films in the first opening part such that each active layer is exposed, wherein a wiring is formed on the second inorganic insulating film and is in contact with each active layer through each contact hole, wherein the capacitor has a first electrode formed from the same conductive film as each gate electrode, a second electrode formed from the same conductive film as the wiring, and a part of the first and second inorganic insulating films which overlap the first electrode and the second electrode in the second opening part, and wherein a curvature radius of a surface of the organic resin film becomes longer continuously as the organic resin film separates from the first and second opening parts.
