Abstract: A normally-closed liquid crystal display includes a component to selectively absorb characteristic leakage light occurring at black representation. Therefore, when black is displayed, occurrence of unnecessary leakage light due to partial depolarization of polarized light caused by a component of an LCD panel can be suppressed. It is therefore possible to provide a liquid crystal display in which display performance of black is improved to clearly display black.

Abstract: A color correction table which contains a correspondence relationship between a discrete input color signal and an output color signal is employed. An inputted color signal is corrected by a signal correcting unit, and an approximating unit acquires a discrete input color signal approximated to the corrected input color signal. A table referring unit refers to the color correction table to output an output color signal which corresponds to the input color signal approximated by the approximating unit. An approximate error producing unit calculates an approximate error from difference between the input and output signals supplied to the approximating unit, and then stores this calculated approximate error into a data holding unit. The stored approximate error is supplied to a signal correcting unit to be used in the correction of the input signal.
