<P>PROBLEM TO BE SOLVED: To materialize a structure with a manufacturing cost curtailed and its operation resistant to being affected by usage conditions as to a generation circuit of a voltage signal for controlling the scanning direction of a scan-line drive circuit. <P>SOLUTION: A voltage signal generation circuit includes a voltage signal generator, an initialization terminal IRT supplied with an initialization signal IRS, and first and second clock terminals CK1 and CK2 supplied severally with clock signals CLK and CLK different in phase. A determination circuit 21 determines the order of activation of the clock signals CLK and CLK correspondent to the activation of the initialization signal IRS to set the levels of first and second voltage signals Vn and Vr, based on the result of the determination. <P>COPYRIGHT: (C)2011,JPO&INPIT |
