Abstract: PURPOSE:To lower the dielectric strength of a switching element without making the constitution complex by inverting a reference voltage supplied to a 2nd connection line to the opposite polarity from application to a 3rd connection line. CONSTITUTION:When one line is driven, a following (below) line is driven similarly. When the following line is driven, TFTs 57jk and 21j on the last line turn OFF. In each picture element unit 50jk, electrodes 54ajk and 54bjk and a reflecting plate form a sort of capacitor, so the applied voltage is held until a next frame is driven. After a display of a video signal of one frame (one image plane) is finished, a frame driver 23 switches the value of the reference voltage vc from 0V to 30V in a period of a next frame. Further, a source driver 25 outputs a voltage Vs corresponding to the polarity-inverted video signal. Consequently, respective picture element units are driven, line by line, as mentioned above. The operation is repeated, frame by frame.
