Abstract

A driving circuit for a display apparatus is provided which apparatus includes pixels allowed to produce a display image by specific voltages applied thereto. The driving circuit includes: a first voltage output means for generating an interpolated voltage on the basis of gray-scale reference voltages supplied thereto, and applying the interpolated voltage to the pixels, the interpolated voltage being of a level between the voltage levels of the gray-scale reference voltages; and a second voltage output means for applying, to the pixels, a voltage different from the gray-scale reference voltages.
