In a multi-gradation voltage generating apparatus, a first gradation voltage generating circuit includes a series circuit formed by "M" (M=1, 2, . . . ) resistors. The series circuit has a first end adapted to receive a first reference gradation voltage from the exterior and a second end adapted to receive a second reference gradation voltage from the exterior. A second gradation voltage generating circuit includes "M" unit circuits each connected between ends of one of the resistors. Each of the unit circuits is constructed by one voltage divider and one voltage follower connected in series. The voltage divider is adapted to generate a plurality of gradation voltages.
