LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display device which has higher definition and reduced power consumption while its image quality is maintained is provided. A switching transistor of an active matrix liquid crystal display device is formed using a transistor having an extremely low off-state current to reduce the area of a capacitor; the capacitance value of parasitic capacitance formed by the left end of a pixel electrode and a first source line is made to be approximately the same as that of parasitic capacitance formed by the right end of the pixel electrode and a second source line; and video signals having one polarity are input to the first source line, and video signals having the other polarity are input to the second source line.
