Abstract
A liquid crystal color display device comprises: a two-layer structured transparent electrode in an identical pattern provided on a transparent substrate forming a liquid crystal; a color filter membrane disposed between said two-layered transparent electrodes by an electrically setting method; and a plurality of pinholes of a size less than 50 .mu.m formed in a same number on each display part at the equal distance to each other in a smaller distance than the pitch between each display part, through which said first layer and second layer of the transparent electrode are electrically connected to each other. The process for manufacturing the liquid crystal color display device comprises: forming a first layer electrode; forming photoresists and coating a color filter membrane; forming a plurality of pinholes in a dot form; forming a second layer transparent electrode through three steps of tentative, main and repeating baking treatments and connecting electrically the two layers of the electrode via the pinholes.
