Abstract

Disclosed is a plasma addressed liquid crystal display improved to prevent deterioration of liquid crystal and an alignment film due to ultraviolet rays generated by plasma discharge. The plasma addressed liquid crystal display includes a liquid crystal cell including columns of signal electrodes, a plasma cell including rows of discharge channels, and an intermediate thin glass sheet through which the liquid crystal cell is joined to the plasma cell. The thin glass sheet includes an ultraviolet ray transmission preventive layer having a function of absorbing or reflecting ultraviolet rays generated in the discharge channels on the plasma cell side thereby preventing the ultraviolet rays from being made incident on the liquid crystal cell side.
