Patent ID: 8405596

Claim:
A matrix-type display device comprising: a pixel array including a plurality of two-dimensionally arranged pixel circuits, a plurality of scanning signal lines, and a plurality of video signal lines; a first scanning signal line driver circuit connected to one end of each of the scanning signal lines and driving the scanning signal lines; a second scanning signal line driver circuit connected to the other ends of the scanning signal lines and cooperating with the first scanning signal line driver circuit to drive the scanning signal lines; and a video signal line driver circuit for driving the video signal lines, wherein, the first and second scanning signal line driver circuits each include a shift register for outputting selection signals for the scanning signal lines, and a plurality of amplifier circuits configured by connecting a plurality of switches in multiple stages, the amplifier circuits amplifying and applying the outputs from the shift register to the scanning signal lines, the first and second scanning signal line driver circuits respectively have only a single first and second switch provided in a last stage of their amplifier circuits, at least one of the first and second switches being an NMOS switch or a PMOS switch, and PMOS and NMOS switches are alternately provided as the first switches in accordance with the order of arrangement of the scanning signal lines, such that each switch is repeated a predetermined number of times before alternating with the other, and PMOS and NMOS switches are alternately provided as the second switches in reverse order to the first switches, such that each switch is repeated the predetermined number of times before alternating with the other.
