  • Method for making a high contrast liquid crystal display including laser scribing opaque and transparent conductive strips simultaneously
    Patent number: 5187601
    Abstract: A method for forming a resistance-reducing electrode pattern in an electrooptical device includes the steps of: forming a transparent conductive film on a substrate; forming a plurality of opaque conductive strips on the film; and scribing the combined structure with a laser through the two layers to simultaneously divide the conductive strips into two parts and pattern the transparent film. In this manner, a pattern of transparent electrodes bordered with an opaque electrode pattern is formed. In specific embodiments, the opaque strips may comprise chromium, and the opaque conductive strips may be formed prior to application of the steps above by laser scribing an applied opaque film layer.
