Abstract: When a semiconductor device is provided with an inverter comprising a transistor having a first gate and a second gate, the semiconductor device does not require a circuit for generating a potential to be input to the second gate of the transistor and has a small number of wirings. Moreover, a semiconductor device having high reliability is provided. The semiconductor device includes a plurality of stages of circuits each provided with two inverter circuits in parallel. Two inverter circuits in a given stage output respective signals of opposite polarities, which is utilized for interchanging signals output from inverter circuits in the previous stage. Thus, an inverted signal is input to the second gate of the transistor included in each of two inverter circuits in the subsequent stage.

Abstract: To provide a display device with high image quality and fewer terminals. The present invention is made with a focus on the positional relation between a serial-parallel conversion circuit and an external connection terminal for supplying a serial signal to the serial-parallel conversion circuit. The structure conceived is such that a serial-parallel conversion circuit and an external connection terminal for supplying a serial signal to the serial-parallel conversion circuit are provided close to each other so that an RC load between the serial-parallel conversion circuit and the external connection terminal is reduced.

Abstract: A novel method for driving a display device in which generation of flickers caused by rewriting pixels is reduced and which has a high aperture ratio is provided. The driving method includes a first step of determining whether displayed still image data is two-valued still image data or multivalued still image data, and a second step of performing display by rewriting (refreshing) the two-valued still image data with lower frequency than the multivalued still image data.
