Abstract

The present invention provides a method for forming a liquid crystal display comprising: providing a liquid crystal display substrate; and forming a light-shielding film for a display on the liquid crystal display substrate by coating the liquid crystal display substrate with a coating liquid containing a binder and fine metal particles, such as fine silver particles, dispersed in the binder, and optionally a dispersant by use of a spin coat method, a curtain coat method, or an extrusion method, and drying the resultant layer, and optionally forming a protective layer on the layer and exposing the protective layer to light.

Claims (28)
