Abstract: A liquid crystal display device includes a plurality of pixels, each including a thin-film transistor and a pixel electrode formed above a substrate, and an organic insulation film formed between one electrode of the thin-film transistor and the pixel electrode. The one electrode and the pixel electrode are connected through a contact hole formed in the organic insulation film, and a sidewall of the contact hole, which is made of the organic insulation film, is tapered. An underlying layer beneath the organic insulation film, in contact with to the organic insulation film, includes a lowermost plane extending substantially in parallel to a plane of the substrate and an uppermost plane extending substantially in parallel to the plane of the substrate. A single step of the underlying layer is formed so as to extend between the lowermost plane and the uppermost plane.

Abstract: A display device includes a thin film transistor; a first organic insulating film covering the thin film transistor and containing a resin material; an inorganic insulating film on the first organic insulating film; a pixel electrode electrically connected with the thin film transistor; a second organic insulating film covering an end of the pixel electrode and exposing a top surface of the pixel electrode; and an organic layer provided on the top surface of the pixel electrode and including a light emitting layer. As seen in a plan view, the inorganic insulating film has an opening, overlapping the second organic insulating film, at a position not overlapping an opening provided in the first organic insulating film. The first and second organic insulating films face each other in the opening in the inorganic insulating film, with an oxide conductive film being between the first and second organic insulating films.
