PROBLEM TO BE SOLVED: To decrease the scale of a circuit in the gate selection circuit of an active matrix liquid crystal panel. SOLUTION: A plurality of clock signals Ck1/Ck2/Ck3/Ck4 are generated by a clock generation circuit 110. A shift register is formed of a plurality of latch circuits LA1(LA11to LA1n) and holding information Gdata is shifted in synchronization with enable clock signals Enable1/Enable2. Then, in a switch circuit SW1(SW11to SW1m), the plurality of clock signals Ck1/Ck2/Ck3/Ck4 are sequentially output as gate selection signals Gate , Gate , Gate , Gate , ..., Gate in accordance with output signals Q1, Q3, ... of the latch circuits LA1(LA11to LA1n).
