Abstract
A method for forming a liquid crystal display device includes forming a metal film over a drive substrate, and patterning the metal film to form at least one pixel electrode and an optical shield film. The optical shield film is provided outside of a pixel electrode area and has a width greater than a width of each of the pixel electrode. A resin is deposited over the patterned metal film, and the resin is patterned to form at least one pole spacer and strip spacer. The strip spacer surrounds the pixel electrode area and has a width greater than a diameter of each of pole spacer. Liquid crystal material is supplied into an inside space which is surrounded by the strip spacer, and a sealing material is filled at outer edges of the strip spacer for fixing the drive substrate and a common substrate.
