摘要：
In an organic electroluminescence (EL) display device, a display region and a first frame region are defined in a substantially circular shape or a substantially oval shape, and in a bending portion, an opening is formed in an inorganic layered film, and a frame flattening film is provided to fill the opening. An end portion of the opening on the display region side is formed along an arc of the first frame region on the bending portion side.
