ABSTRACT:
A driver IC (integrated circuit) for a display device allowing simple designing and production and yet capable of obviating display quality difference is provided. The driver IC includes a plurality of drive signal output terminals arrange to have variable drive capacities which vary depending on loads of respective signal electrodes of the display device to which the output terminals are connected so as to supply the respective signal electrodes of the display device with drive signal waveforms having identical time constant. The driver IC preferably includes a number of juxtaposed transistors corresponding to but larger in number than the drive signal output terminals, wherein the respective drive signal output terminals are connected to prescribed numbers of transistors so as to have different drive capacities depending on loads of the signal electrodes of the display device to which the output terminals are connected.
