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.
