Abstract
A semiconductor display device with which flicker, vertical striping, and horizontal striping are not easily seen, and a method of driving the semiconductor display device, are provided. Display signals inputted to a plurality of pixel electrodes have a positive or negative polarity based on the electric potential of an opposing electrode, and pixel electrodes to which display signals having a positive polarity are inputted, and pixel electrodes to which display signals having a negative polarity are inputted, differ for each frame period with the method of driving the semiconductor display device.
