Abstract: To provide a light-emitting device capable of suppressing the display of an afterimage. A plurality of pixels arranged in n rows and m columns (n and m are each an integer of 2 or more) is supplied with a first signal containing image data and a second signal for initializing the pixels. Each pixel includes a first transistor for controlling the input of the first signal and a second transistor for controlling the input of the second signal. The first transistor in a k-th row (k is an integer of 1 to n) and the second transistor in a k+1-th row are turned on at the same time, so that the pixels are initialized and display images effectively.

Abstract: A novel liquid crystal display device is provided.Two pixels each include a transistor that includes a back gate. The transistor is connected to the common gate line and data line. A threshold voltage is controlled by a control signal supplied to a back gate so that while data is written to one pixel, the transistor of the other pixel is not turned on. The aperture ratio is improved by reducing the number of wirings connected to the pixel and increasing the frequency of the control signal supplied to the back gate.
