摘要： The amplitude voltage of a signal input to a level shifter can be increased and then output by the level shifter circuit. Specifically, the amplitude voltage of the signal input to the level shifter can be increased to be output. This decreases the amplitude voltage of a circuit (a shift register circuit, a decoder circuit, or the like) which outputs the signal input to the level shifter. Consequently, power consumption of the circuit can be reduced. Alternatively, a voltage applied to a transistor included in the circuit can be reduced. This can suppress degradation of the transistor or damage to the transistor.

摘要： One of the objects is to improve display quality by reduction in malfunctions of a circuit. In a driver circuit formed using a plurality of pulse output circuits having first to third transistors and first to fourth signal lines, a first clock signal is supplied to the first signal line; a preceding stage signal is supplied to the second signal line; a second clock signal is supplied to the third signal line; an output signal is output from the fourth signal line. Duty ratios of the first clock signal and the second clock signal are different from each other. A period during which the second clock signal is changed from an L-level signal to an H-level signal after the first clock signal is changed from an H-level signal to an L-level signal is longer than a period during which the preceding stage signal is changed from an L-level signal to an H-level signal.

摘要： A display device in which partial driving can be performed with a simplified configuration of a circuit including a wiring. One of signal processing circuits includes a first transistor that controls the potential of its respective gate signal line, and a second transistor that outputs a start signal for the subsequent stage and a reset signal for the preceding stage. A signal for controlling whether the gate signal line is in an active state (a state where a selection signal is output) or a non-active state (a state where a selection signal is not output or a non-selection signal continues to be output) is input to the first transistor. A clock signal is input to the second transistor. Thus, the number of wirings necessary for operating the device is reduced.
