Abstract: A novel semiconductor device is provided. The semiconductor device is a single-polarity semiconductor device including a vertical-channel transistor. In the vertical-channel transistor, the higher parasitic capacitance value of the gate-source parasitic capacitance and the gate-drain parasitic capacitance is used as a bootstrap capacitor, which decreases the occupied area of the semiconductor device. The use of an oxide semiconductor for a semiconductor layer of the vertical-channel transistor increases the breakdown voltage between the source and the drain, which can shorten the channel length. In addition, stable operation can be performed even in a high-temperature environment.

Abstract: 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.

Abstract: It is an object to provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.
