of counter electrodes a voltage is output by a drain of a first switching three terminal element that is selected in accordance with electrode line x and y thereby storing a charge in a signal voltage storing capacitor and applying it to a gate of a second switching three terminal element voltage is applied to the unit circuit area whereby the picture element electrodes are energized by the application of this voltage a closed circuit is completed from one of the counter electrode 34 b 34 the liquid crystal layer 34 c 2 34 one of the picture element electrodes 34 a 34 the tft 2 i e from the source to the drain of the second switching three terminal element the other picture element electrode 34 a 39 34 the crystal liquid layer 34 c 39 2 34 and the other counter electrode 34 b 39 34 the picture element electrodes display when the liquid crystal layer is driven by the application of an a c voltage referring to fig1 and 2 the electrode lines x 1 x 2 and so on are bus lines for data signals and the lines y 1 y 2 and so on are also bus lines for scanning signals these electrode lines x and y are crossed in an electrically isolated state that is with the interposition of insulating films hereinafter referred to as to as 34 crossover 34 a first tft 1 is located adjacent to one of the crossover whose gate is connected to the line y y 1 and whose source is connected.
