<p><P>PROBLEM TO BE SOLVED: To provide a display device which can have its display quality improved and its frame made small. <P>SOLUTION: A signal line driving circuit has a latch circuit which latches digital pixel data, a D/A converter which converts the latch output of the latch circuit into an analog video signal, an AMP 17 which amplifies the analog vide signal generated by the D/A converter, and a signal line selecting circuit 18 which selects a signal line as the supply destination of the analog video signal amplified by the AMP 17, which has odd numbers of cascaded inverters IV1 to IV3, capacitor elements C4 and C5 connected between the stages of the inverters and between the input terminal of the inverter of the starting stage and the output terminal of the final stage, a 1st power supply line XAVDD 1 which supplies a source voltage to the inverter INV1 of the starting stage, and a 2nd power supply line XAVDD2 which supplies the source voltage to the inverters other than the inverter of the starting stage. Thus only the power supply line of the starting-stage inverter is separated to improve the precision of the AMP 17. <P>COPYRIGHT: (C)2003,JPO</p> |
