Abstract
A liquid crystal display (LCD) substrate and a fabrication method thereof are provided. The LCD substrate comprises a substrate, a spacer definition layer formed on the substrate comprising a first step, and a spacer formed along a profile of the first step of spacer definition layer and adjacent to the first step, thereby forming a second step on the spacer. The invention utilizes a single photolithographic process to form spacers with steps, thus, effectively lowering the probability of mura defects caused by gravity, contact, or an uneven cell gap.
