  • Patent number: 7812915
    Abstract: A method of fabricating a liquid crystal display includes aligning a mask on a substrate, applying surface treatment to the substrate using light that has passed through the mask, forming a spacer pattern at the surface treated area, and forming a spacer by hardening the spacer pattern. Surface treatment is applied to the area where a spacer is to be formed by an ion beam, ultraviolet radiation or a laser beam. By forming the spacer at the surface treated area using an ink jet, it is possible to control the shape and height of the spacer. Also, since the ink jet is located at the surface treated area, it become easier to align the ink jet to accurately form the spacer at the desired place.
