Abstract
A liquid crystal display of the present invention contains a first panel and a second panel being stacked. Adjacent pairs of polarizers (A to C) disposed on the panels form crossed Nicols. When the first panel produces a display according to a first display signal, the second panel produces a display according to a second display signal obtained from the first display signal. Each of the two joined panels is provided with a light diffusion layer having a light diffusing property. The provision of the light diffusion layers enables reducing moire pattern occurrences which would otherwise markedly increase when two liquid crystal panels are stacked. As a result, the liquid crystal display has high display quality.
