An active matrix liquid crystal display of (2×1) dot inversion driving system, wherein in a case where the active matrix display is driven, voltage is applied to the pixels in such a manner that polarity is changed every source line in the horizontal direction and every two gate lines in the vertical direction. Further, a plurality of pixels is provided with a switching element, and charging characteristics of the pixels are made uniform both at the time of selecting the n-th line gate wire 1 at which the polarity of the source potential is inverted and at the time of selecting the (n+1)th line gate wire 2 at which no inversion is made in the source potential, whereby unevenness in luminance occurring in each line in raster display can be reduced.
