Abstract: A gate drive circuit includes a shift register having a plurality of stages, in which an n-th stage (‘n’ is a natural number) of the plurality of stages is connected to at least one subsequent stage. The n-th stage includes a pull-up part configured to output a high voltage of an n-th gate signal using a high voltage of a clock signal as in response to a high voltage of a control node, a control pull-down part configured to pull-down a voltage of the control node into a low voltage in response to a carry signal outputted from at least one of next stages of the n-th stage and receiving a back-bias voltage corresponding to the low voltage, and a carry part configured to output the high voltage of the clock signal as an n-th carry signal in response to a high voltage of the control node.

Abstract: A display panel includes a plurality of pixels which is arranged in a pixel column and a pixel row, a gate line which is connected to pixels in a same pixel row, a first data line which is connected to pixels in a same pixel column, and a second data line which is connected to remaining pixels except for the pixels connected to the first data line among the pixels in the same pixel column. Two odd-numbered pixel rows and two even-numbered pixel rows are alternately driven so that a charge period of the pixel may be extended by 2H. In addition, a kickback difference between the odd-numbered pixel row and the even-numbered pixel row may be decreased so that a display quality may be improved.
