Method for forming post spacers in liquid crystal display |
摘要 |
The present invention relates to a method for forming post spacers in a liquid crystal display, which enables cell gap to be uniform by means of a half-tone mask. The method comprises the steps of: defining a active region and a dummy region in a substrate; forming a black matrix on the substrate at the outside of the active region; selectively forming a RGB resin film on the active region while selectively forming a RGB resin film on the dummy region; forming a protective film on the resulting structure; forming a photosensitive resin film on the protective film; forming a half-tone mask pattern on the photosensitive resin film; and selectively etching the photosensitive resin film using the half-tone mask pattern so as to form the post spacers having a different height.
