PURPOSE:To divide a driving output, to drive a picture element and to execute at high speed and with high resolution by connecting plural logical gates to one output terminal of the driving circuit and applying a different selecting pulse to a gate. CONSTITUTION:During the period of the time t1-t3, an electric potential of an output terminal 114 of the driving circuit 101 goes to 'H'. During the time t1-t2, a selecting pulse 503 impressed to a terminal 117 goes to 'H', an output signal 505 of a logical gate 102 goes to 'H' and a picture element 108 is driven. During the period t2 t3, a selecting pulse 504 impressed to a terminal 118 goes to 'H', an output signal 506 of a logical gate 103 goes to 'H' and a picture element 109 is driven. In the same way, During the respective periods t3 t4 and t4 t5, picture elements 110 and 111 are respectibely driven. The above- mentioned action is repeated, a picture element 113 is driven and thereafter, the scanning of one line is completed.
