Zusammenfassung:	PROBLEM TO BE SOLVED: To provide highly precise signal output by canceling the influence of electric potential fluctuation due to a coupling capacity in switching operation in a drive circuit for a display unit. SOLUTION: The coupling capacity between a control line CL1 and a capacity element 210 is substantially equal to the coupling capacity between a control line CL2 and the capacity element 210 by constituting layout so that the control lines CL1, CL2 are linearly symmetrical for a reference line A-A connecting the input and output of the capacity element 210, when the control element 220 is switched, the influence of the electric potential fluctuation generated between each signal line CL and the capacity element 210 is mutually canceled, and the electric potential fluctuation does not occur at analog electric potential held on the capacity element 210.
