Abstract:
A plasma addressed liquid crystal display, comprising:a liquid crystal cell including columns of signal electrodes and a liquid crystal material and at least on alignment layer;a plasma discharg cell including rows of discharge channels, said plasma discharge cell underlying said liquid crystal cell, said plasma discharge cell being operable to generate a plasma discharge which results in ultraviolet radiation being emitted from the plasma discharge toward the liquid crystal cell; andan intermediate thin glass sheet through which said liquid crystal cell is joined to said plasma cell;wherein said thin glass sheet includes an ultraviolet ray transmission preventive layer having a function of absorbing or reflecting ultraviolet rays generated by the plasma discharge in said discharge channels on said plasma cell side immediately under said liquid crystal cell thereby substantially preventing the ultraviolet rays generated immediately under said liquid crystal cell from being made incident on said liquid crystal material and said at least one alignment layer of said liquid crystal cell side.
