Abstract:
An active-matrix-type image display device for inputting a digital picture signal, said device comprising:a plurality of pixels arranged in a matrix form; a plurality of data signal lines arranged to correspond to columns of said pixels; and a plurality of scanning signal lines arranged to correspond to rows of said pixels, said active-matrix-type image display device further comprising: gray-scale voltage generating means for generating gray-scale voltages of different levels; a scanning signal line driving circuit for outputting a scanning voltage to said scanning signal lines; and a data signal line driving circuit for selecting a gray-scale voltage according to the picture signal and outputting the selected gray-scale voltage sequentially to each of said data signal lines, wherein said data signal line driving circuit includes one scanning circuit for each of said data signal lines, and outputs a selected gray-scale voltages to each of said data signal lines at different start timings sequentially in one horizontal image display period in synchronization with sequential outputs of active signals from said scanning circuits in said one horizontal image display period.
