PROBLEM TO BE SOLVED: To realize liquid crystal driving which is low in power consumption, fast, and high in precision by providing an output circuit which can disconnect signal output of an impedance converting means from an output terminal and also can output the signal output to the output terminal at a high speed with high precision. SOLUTION: In a precharge period, analog switches A<SB>i</SB>and Bi (i: an integer between 1 and (m)) are turned OFF and analog switches C<SB>i</SB>and D<SB>i</SB>are turned ON, an output terminal which drives a source line S<SB>i</SB>is disconnected from the signal output of a source driver SD<SB>i</SB>and connected to an adjacent output terminal to precharging, and the output terminal is disconnected to the inversion input of the SD<SB>i</SB>to feed the signal output back to the inversion input. In a driving period, the A<SB>i</SB>and Bi are turned ON, the C<SB>i</SB>and D<SB>i</SB>are turned OFF to disconnect the output terminal from the adjacent output terminal and connect it to the signal output, which is disconnected from the inversion input to feed the signal of the output terminal back to the inversion input.
