Active-matrix-type image display device

An active-matrix-type image display device for inputting a digital picture signal, comprising:

• a plurality of pixels arranged in a matrix form;
• a plurality of data signal lines arranged to correspond to columns of said pixels;
• a plurality of scanning signal lines arranged to correspond to rows of said pixels;
• 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 gray-scale voltage to said data signal line,
• wherein said data signal line driving circuit includes one scanning circuit for each of said data signal lines, and selectively outputs the gray-scale voltages to said data signal lines in synchronization with sequential outputs from said scanning circuits in one horizontal period.
