Patent attributes
A display device with low manufacturing cost, a display device with low power consumption, a display device capable of being formed over a large substrate, a display device with a high aperture ratio of a pixel, and a display device with high reliability are provided. The display device includes a transistor electrically connected to a light-transmitting pixel electrode and a capacitor. The transistor includes a gate electrode, a gate insulating film, and a first multilayer film including an oxide semiconductor layer. The capacitor includes the pixel electrode and a second multilayer film overlapping with the pixel electrode, positioned at a predetermined distance from the pixel electrode, and having the same layer structure as the first multilayer film. A channel formation region of the transistor is at least one layer, which is not in contact with the gate insulating film, of the first multilayer film.
