摘要： A display device that can switch between normal display and see-through display is provided. Visibility in see-through display is improved. A liquid crystal element overlaps with a light-emitting element. The light-emitting element, a transistor, and the like overlapping with the liquid crystal element transmit visible light. When the liquid crystal element blocks external light, an image is displayed with the light-emitting element. When the liquid crystal element transmits external light, an image displayed with the light-emitting element is superimposed on a transmission image through the liquid crystal element.

摘要： To provide a highly reliable liquid crystal display device including flexible substrates and a crystalline oxide semiconductor film for a backplane. The device includes a flexible first substrate, a flexible second substrate facing the first substrate, and a liquid crystal layer sealed between the substrates with a sealing member. The first substrate is provided with a layer including a transistor, an organic resin film over the transistor, a pixel electrode and a common electrode over the organic resin film, which partly overlap with each other with an insulating film provided therebetween, and an alignment film thereover. The transistor includes a crystalline oxide semiconductor film as a semiconductor layer where a channel is formed. Drying treatment is performed on the layer before the liquid crystal layer is sealed between the substrates, and steps from the drying treatment to sealing of the liquid crystal layer are performed without exposure to the air.
