Abstract: Damage to a flexible display can be prevented. A display device having improved mechanical strength can be provided. A display device (10) includes a display panel (11) and a protection cover (12). The display panel (11) includes a first portion having flexibility. The protection cover (12) has a light-transmitting property and flexibility and is provided to overlap with a display surface side of the display panel (11). The display device (10) has a function of being reversibly changed in shape to a first mode in which the display panel (11) and the protection cover (12) are each substantially flat and a second mode in which the first portion of the display panel (11) is curved such that the display surface side becomes a concave surface and part of the protection cover (12) is curved in the same direction as the first portion. In the second mode, there is a gap between the first portion and the protection cover.

The pair of pixels includes one pixel and another pixel, and the one pixel includes a light-emitting device and a first microlens. The light-emitting device emits light toward the base material, and the first microlens is interposed between the base material and the light emission and converges light. The first microlens includes a first surface and a second surface; the second surface is closer to the light-emitting device than the first surface is; and the second surface has a smaller radius of curvature than the first surface. The other pixel includes a photoelectric conversion device and a second microlens.

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 includes overlapping two display panels. The display panel on the upper side includes a first display region and a region that transmits visible light. The display panel on the lower side includes a second display region and a region that blocks visible light. The second display region overlaps with the region that transmits visible light. The region that blocks visible light overlaps with the first display region. The display panel on the lower side includes a third display region between the second display region and the region that blocks visible light. The gate signal and the source signal supplied to a first pixel in the third display region are the same as the gate signal and the source signal supplied to a second pixel in the second display region. The second pixel is closer to the first pixel than any other pixels included in the second display region.
