Abstract: PROBLEM TO BE SOLVED: To provide an image of high display quality ensuring a satisfactory viewing angle, having neither persistence of vision nor gradation reversal, and free of flickering and crosstalk with a horizontal electric field system active matrix liquid crystal display. SOLUTION: A scanning signal circuit is first formed, a video signal circuit and a liquid crystal driving electrode are then formed, and common electrodes are finally formed on a passivation layer (uppermost protective layer) on both sides of the video signal circuit in such a way as to shield the electric field of the video signal circuit. The common electrodes are connected on the passivation layer covering the video signal circuit in a horizontal direction (in which the scanning signal circuit extends) or in a vertical direction (in which the video signal circuit extends).
