Abstract: When a base film used in a flexible display panel is bonded to a resin member for fixing the base film that is curved, the base film has creases by an environmental change such as temperature due to difference in linear expansion coefficient before and after a thermal shock. A buffer plate that is thin enough to be bent is provided between the base film used in a flexible display panel and the resin member. With the use of heat dissipation effect and heat equalization effect of the buffer plate, a structure around the panel capable of resisting the environmental change can be provided.

Abstract: A display device capable of performing display at high luminance is provided. A first layer containing a first light-emitting material emitting blue light is formed into an island shape over a first pixel electrode, and then a second layer containing a second light-emitting material emitting light having a longer wavelength than blue light is formed into an island shape over a second pixel electrode. After that, an insulating layer overlapping with a region interposed between the first pixel electrode and the second pixel electrode is formed, and a common electrode is formed to cover the first layer, the second layer, and the insulating layer.
