Abstract: A gate driver includes a gate shift register in which an A block and a B block each having a plurality of stages, the A block and the B block being alternately arranged; scan clock lines inputting a first scan clock group and a second scan clock group each including both image data writing (IDW) scan clocks synchronized with an image write timing and black data insertion (BDI) scan clocks synchronized with a black write timing to the A block and the B block; and carry clock lines inputting carry clocks to the A block and the B block and sense clock lines inputting sense clocks to the A block and the B block, wherein each of the stages belonging to the A block and the B block includes a BDI memory storing a BDI carry signal for outputting the BDI scan clocks.
