Abstract
A reference potential generating circuit for liquid crystal display apparatus includes an outside reference potential generating circuit for generating a pair of outside reference potentials, and an inside reference potential generating circuit for generating a pair of inside reference potentials, which are between the outside reference potentials and are independent of the outside reference potentials. The outside or the inside reference potential generating circuit has a variable resister for correcting a deviation of a center potential of the outside or inside reference potentials.
