Abstract
The present invention is directed to an a.c. driven active matrix liquid crystal display device capable of inhibiting the aforementioned artifact of stripes as well as saving the power consumption, and a method of driving such a device. A selection switch SW controlled by a column selection circuit 50 enables selection of picture signal lines Sb to be connected to a picture signal source 40 by skipping, and since the picture signal lines are divided in two groups such as a group of odd numbered ones and the other group of even numbered ones so that the connection sequence of the groups of them are varied from one of two consecutive periods to another, vivid stripes are prevented from coming up simply upon the connection to the picture signal lines related with any specific color, thereby enhancing the quality of the resultant picture displayed. A plurality of picture signal lines which are selected by a plurality of picture signal selecting circuits may be arranged adjacent to one another.
