Abstract
A display panel drive device of reduced area occupied by circuit elements. The display panel drive device includes an output stage circuit having a low side selector circuit constituted by connecting in series inverters and a buffer circuit, n-channel IGBTs, a Zener diode and resistance respectively connected between the gate and emitter of the IGBT, a buffer circuit, and a high side selector circuit including an inverter. The buffer circuit includes a high side Pch-MOS operated by a logic signal from the high side selector circuit and a low side Nch-MOS operated by a logic signal of the low side selector circuit.
