ABSTRACT:
A liquid crystal display panel is so constructed that a plurality of pixels are arranged in a matrix form having the number of lines twice that of horizontal scanning lines for one field of interlaced scanning video signals obtained by scanning an original image every other line, the arrangement of the pixels being shifted horizontally by one-half of a pixel between adjacent upper and lower lines. A row driving circuit applies, to the pixels in the upper line of the two adjacent upper and lower lines, data voltages obtained by sampling a video signal representing one horizontal scanning line by a clock signal of the timing that matches the number of pixels in the upper line and the arrangement of the pixels, and applies, to the pixels in the lower line, data voltages obtained by sampling the above video signal representing one horizontal scanning line by a clock signal of the timing shifted by 1/2 cycle from the above clock signal. Thus, one horizontal scanning line represented by the video signal is displayed using the two upper and lower lines of pixels, thereby enhancing the display quality of the produced image.
