Abstract: It is an object to provide a display device which can favorably display a image without delayed or distorted signals. The display device includes a first gate driver and a second gate driver. The first gate driver and the second gate driver each include a plurality of flip flop circuits and a plurality of transfer signal generation circuits. Both the flip flop circuit and the transfer signal generation circuit are circuits which output a signal inputted to a first input terminal with a half clock cycle delay. In addition, an output terminal of the transfer signal generation circuit is directly connected to a first input terminal of the flip flop circuit in the next stage. Therefore, delay and distortion of the signal which is inputted from the transfer signal generation circuit to the flip flop circuit can be reduced.

Abstract: 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.

Abstract: With an increase in the definition of a display device, the number of pixels is increased, and thus the numbers of gate lines and signal lines are increased. Due to the increase in the numbers of gate lines and signal lines, it is difficult to mount an IC chip having a driver circuit for driving the gate and signal lines by bonding or the like, which causes an increase in manufacturing costs. A pixel portion and a driver circuit for driving the pixel portion are formed over one substrate. At least a part of the driver circuit is formed using an inverted staggered thin film transistor in which an oxide semiconductor is used. The driver circuit as well as the pixel portion is provided over the same substrate, whereby manufacturing costs are reduced.

Abstract: An object is to provide a semiconductor device which can suppress characteristic deterioration in each transistor without destabilizing operation. In a non-selection period, a transistor is turned on at regular intervals, so that a power supply potential is supplied to an output terminal of a shift register circuit. A power supply potential is supplied to the output terminal of the shift register circuit through the transistor. Since the transistor is not always on in a non-selection period, a shift of the threshold voltage of the transistor is suppressed. In addition, a power supply potential is supplied to the output terminal of the shift register circuit through the transistor at regular intervals. Therefore, the shift register circuit can suppress noise which is generated in the output terminal.

Abstract: To provide a display device in which rewriting of only a given section of an image can be achieved or to simplify the configuration of a circuit including wirings in a display device in which partial driving can be performed. A shift of a selection signal in a shift register included in a scan line driver circuit and supply of a selection signal to scan lines are controlled independently of each other, so that rewriting of only a given section of an image can be achieved. The above operation is realized by providing a wiring that supplies a signal representing a clock signal or a fixed potential. Therefore, the configuration of the circuit including the wiring can be simplified in the display device including the wiring while partial driving can be performed.
