Abstract
A driver for driving a liquid crystal panel that includes a pair of substrates, a liquid crystal sandwiched between the substrates, a plurality of signal lines (31) which are arranged in a first given direction on a substrate and to which an image signal is supplied, a plurality of scanning lines (32) which are arranged in a second direction and to which a scan signal is supplied sequentially, and a plurality of pixels arranged in the form of a matrix on the surface of a substrate opposed to the liquid crystal, and driven with the image signal and scan signal supplied over the plurality of signal lines and plurality of scanning lines comprises: an image signal supply unit (101 to 104) including a first-direction shift register that has a plurality of stages (1a) and supplying the image signal sequentially to the plurality of signal lines in a first direction according to a transfer signal sequentially generated by the first-direction shift register, and a scan signal supply unit including a second-direction shift register (2) that has a plurality of stages and supplying the scan signal sequentially to the plurality of scanning lines in a second direction according to a transfer sig…
