Abstract
A drive circuit of a display device includes decoder circuit which outputs a voltage based on a 8-bit digital value. The decoder circuit includes a first decoder circuit and a second decoder circuit which output one voltage respectively using upper-order 6 bits of the 8-bit digital value; a selection circuit which receives voltages outputted from the first decoder circuit and the second decoder circuit, and distributes the two voltages to three terminals; and an intermediate voltage output circuit which outputs an intermediate voltage which is a one of five kinds of values based on the three voltages. The first decoder circuit and the second decoder circuit respectively include a select-switch-type decoder circuit and a tournament-type decoder circuit.
