摘要

A reference voltage generating circuit which generates reference voltages at a plurality of levels, a voltage follower circuit for stabilizing the reference voltages at a plurality of levels and a gray scale voltage generating circuit which generates gray scale voltages at a plurality of levels from the stabilized reference voltages are provided. The voltage follower circuit includes a differential amplifier which receives at one input the reference voltages, first and second buffer circuits connected in parallel to each other, and a resistor. Outputs of the first and second buffer circuits are connected to each other through the resistor, with the output of the first buffer circuit being fed back to the other input of the differential amplifier and the output of the second buffer circuit being connected to serve as an output of the voltage follower circuit.
