Abstract
The present invention relates to a shift register in which a structure of a switching device of an output buffer unit is changed for reducing power consumption. The shift register includes a plurality of stages each having a plurality of switching devices, for forwarding a scan pulse in succession, wherein the at least one of the plurality of switching device has a first area at which a gate electrode thereof overlaps with a first electrode thereof with a size different from a second area at which the gate electrode overlaps with a second electrode thereof.
Claims8
A shift register comprising:
- a plurality of stages each having a plurality of switching devices, for forwarding a scan pulse in succession,
- wherein at least one of the plurality of switching device has a first area at which a gate electrode thereof overlaps with a first electrode thereof being smaller than a second area at which the gate electrode overlaps with a second electrode thereof,
- wherein a clock pulse is applied to the first electrode.
