ABSTRACT:
A liquid crystal display device includes a liquid crystal display device, a vertical scanner, a horizontal scanner, a video driver, a timing generator, and termination means. The liquid crystal panel is provided with pixels arranged in a matrix. The vertical scanner operates in accordance with a first start-pulse signal, and sequentially selects each row of the pixels. The horizontal scanner operates in accordance with a second start-pulse signal, and sequentially writes a video signal to the selected row of the pixels by distributing the video signal to each column of the pixels. The video driver, which is activated in accordance with supply of power, supplies the video signal to the liquid crystal panel. The timing generator, which is activated in accordance with the supply of power, supplies the first start-pulse signal and the second start-pulse signal to the vertical scanner and the horizontal scanner, respectively. The termination circuit terminates at least either of the first start-pulse signal and the second start-pulse signal which are repeatedly inputted to the vertical scanner and the horizontal scanner until the video signal outputted from the video driver becomes stable when power is supplied.
