An object of the invention is to provide the miniaturized gray scale voltage outputting device. A gray scale voltage outputting device ( 6 ) for receiving an image signal (Si) to output a gray scale voltage comprises a gray scale voltage group outputting means ( 600 ) having a plurality of gray scale voltage group outputting portions, each of which outputs a gray scale voltage group having a plurality of gray scale voltages in such a way that said plurality of gray scale voltages are sequentially outputted from said respective gray scale voltage group outputting portions during an gray scale voltage group outputting period (Pv) corresponding to a selection period of a source bus (Bs), a selector ( 62 ), having a plurality of gray scale voltage group inputting portions (In 1 to In 32 ) for receiving said gray scale voltage groups (G 1 to G 32 ) outputted from said plurality of gray scale voltage group outputting portions (Out 1 to Out 32 ), for selecting from said gray scale voltage groups (G 1 to G 32 ) received by said plurality of gray scale voltage group inputting portions (In 1 to In 32 ) to output said selected gray scale voltage group and a switch ( 63 ) for selecting, from said plurality of gray scale voltages comprised by said gray scale voltage group outputted from the selector ( 62 ), a gray scale voltage which is to be outputted from said gray scale voltage outputting device.
