Claim 4:
5. A display device comprising:
a first display panel comprising a substrate having flexibility, an EL element, and a first transistor,
wherein the first display panel is configured to overlap with a second display panel comprising a glass substrate and a second transistor,
wherein, in a state where a display surface of the first display panel is flat, the display surface of the first display panel comprises a first region overlapping with a display surface of the second display panel and a second region not overlapping with the display surface of the second display panel,
wherein, when the display surface of the first display panel is bent, the second region and the first region are configured to overlap each other,
wherein, when the display surface of the first display panel is bent, the display device comprises a member that protects a region having a curvature of the display surface of the first display panel and is sandwiched by the first display panel,
wherein the member is not a film-like material,
wherein, in the state where the display surface of the first display panel is flat, the first display panel displays an image by emitting light towards a side where the member is provided, and
wherein, in the direction in which the light is emitted, the member is closer to the user than the first display panel.
