A selector circuit, for selecting and outputting, in accordance with N-bit input data, one gray level reference voltage from 2N gray level reference voltages, comprises: a plurality of select transistor arrays, which are provided in parallel between terminals of the gray level reference voltages and an output terminal and which have a plurality of serially connected transistors that are drive-controlled by the input data, wherein the select transistor arrays are each commonly provided for a group of M (M is a plurality and M<2N) gray level reference voltages among the 2N gray level reference voltages and are made to assume a drive enabled state by means of time division in correspondence with the M gray level reference voltages.
