    Abstract: Two gate drivers each comprising a shift register and a demultiplexer including single conductivity type transistors are provided on left and right sides of a pixel portion. Gate lines are alternately connected to the left-side and right-side gate drivers in every M rows. The shift register includes k first unit circuits connected in cascade. The demultiplexer includes k second unit circuits to each of which a signal is input from the first unit circuit and to each of which M gate lines are connected. The second unit circuit selects one or more wirings which output an input signal from the first unit circuit among M gate lines, and outputs the signal from the first unit circuit to the selected wiring(s). Since gate signals can be output from an output of a one-stage shift register to the M gate lines, the width of the shift register can be narrowed.

    Abstract: A semiconductor device which has reduced power consumption and includes a selection transistor is provided. A semiconductor device in which the number of wirings and terminals for inputting a power supply potential is reduced and which operates at high speed is provided. A buffer circuit connected to a gate line connected to a gate of the selection transistor has a function of generating a potential higher than a high power supply potential by using the high power supply potential and outputs the potential depending on the selection signal. A bootstrap circuit boosts a high power supply potential that is input to an inverter that is the closest to an output side among a plurality of inverters included in a buffer circuit. Further, by providing a delay circuit in the buffer circuit, the bootstrap circuit starts to boost a potential at the timing later than the input of the selection signal.
