ABSTRACT:
A digital driver for display devices which can prevent the delay of digital data and the extended transition time of the digital data, and thus can make good display, and a display device including the above-mentioned digital driver are disclosed. The digital driver according to the present invention is constituted in such a manner that, by successively inputting digital data to a shift register, the digital data are shifted in the shift register, and the resulting output is sent out to latch circuits. Since the digital data are directly inputted to the shift register, the distance over which the data lines are laid around can be shortened, the increase in load due to the laying-around of the data lines which has so far been a problem can be prevented, and the delay of the digital data and the extended transition time of the digital data can be prevented.
