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.

摘要： A liquid crystal display device which is resistant to physical impact and can retain high-quality display characteristics is provided. Further, a liquid crystal display device with high reliability and high performance is provided. In a liquid crystal display device in which a liquid crystal composition is interposed between a pair of substrates, a spacer for keeping a gap between the substrates is provided over a structure body provided under a pixel electrode layer or a common electrode layer. The structure body is provided to make the pixel electrode layer and the common electrode layer project into the liquid crystal composition, and the structure body is provided to extend to a region where the spacer is provided. Since the structure body is formed using one continuous film, regions of the surface thereof have substantially the same height and the spacer can be stably provided with good adhesion.
