Patent attributes
A display device includes a hole portion provided in a non-display region. A first opening that surrounds the hole portion is formed in at least one inorganic insulating film in a plurality of inorganic insulating films of the non-display region. A sealing inorganic insulating film includes an edge sealing portion in a frame shape, the edge sealing portion being formed so as to cover an edge of the at least one inorganic insulating film around the hole portion. A reverse-tapered bank structure portion in a frame shape and a protruding portion including an inorganic film in a frame shape are formed to surround the first opening on the at least one inorganic insulating film. Both side surfaces of the reverse-tapered bank structure portion are tilted in a reverse tapered shape whose width between both the side surfaces gradually decreases toward a side of a resin substrate.
