  • Patent number: 11869453
    Abstract: To provide a semiconductor device including a narrowed bezel obtained by designing a gate driver circuit. A gate driver of a display device includes a shift register unit, a demultiplexer circuit, and n signal lines. By connecting the n signal lines for transmitting clock signals to one stage of the shift register unit, (n?3) output signals can be output. The larger n becomes, the smaller the rate of signal lines for transmitting clock signals which do not contribute to output becomes; accordingly, the area of the shift register unit part is small compared to a conventional structure in which one stage of a shift register unit outputs one output signal. Therefore, the gate driver circuit can have a narrow bezel.
