ABSTRACT:
Disclosed is a method of fabricating a liquid crystal display (LCD) device in which a photosensitive film is selectively patterned using a half-tone mask, and then a portion of a passivation layer at a pixel area is selectively removed to secure an penetration path of a stripper. Additionally, a crack is generated on a conductive film formed on a photosensitive film pattern through a predetermined heat treatment to facilitate a lift-off process. Thus, the number of masks can be reduced to simplify the fabrication process of the LCD device and reduce fabrication costs.
