Method for manufacturing a light-dispersion type liquid crystal display device

Claim 1

A method for manufacturing an LCD device, comprising the steps of: forming a patterned first electrode over a substrate; forming a light-transmitting insulating layer over said patterned first electrode and exposed portions of said substrate; forming a photosensitive medium layer over said insulating layer; forming another light-transmitting insulating layer over said photosensitive medium layer; alternately performing said forming a photosensitive medium layer and said forming another light-transmitting insulating layer a selected number of times, to thereby form a multilayer laminated structure comprised of a plurality of insulating layers and photosensitive medium layers, an uppermost layer of said multilayer laminated structure comprising a final insulating layer; positioning a patterned photomask above said final insulating layer and irradiating portions of said multilayer laminated structure not covered by said patterned photomask, to thereby create exposed regions and unexposed regions within each of said photosensitive medium layers; forming a patterned second electrode over said final insulating layer, said patterned second electrode covering first portions of an upper surface of said final insulating layer, with second portions of said upper surface of said final insulating layer being left uncovered by said patterned second electrode; forming inlet holes in said multilayer structure, each of said inlet holes extending from said second portions of said upper surface of said final insulating layer down to an upper surface of said patterned first electrode; applying a developer through said inlet holes to dissolve said exposed regions in each of said photosensitive medium layers, to thereby form a plurality of layered cavities in communication with said inlet holes; and, filling each of said inlet holes and each of said plurality of layered cavities with liquid crystal material.

Claim 2
