ABSTRACT:
A polymer dispersed liquid crystal display device having a liquid crystal layer inserted between opposed glass plates and comprising a layer of resin and liquid crystal capsules dispersed in the resin. The liquid crystal capsules are substantially uniformly distributed all over the liquid crystal panel, even if a black matrix and bus lines provided in the glass plates may act as a shading layer when an ultraviolet light is irradiated to cure the resin and to form the liquid crystal capsules. The uniformly distributed liquid crystal capsules can be obtained by the manufacturing method comprising the step of irradiating the ultraviolet light obliquely to a surface of the glass plate having the shading layer for curing the resin material.
