Abstract
A method for fabricating a display substrate is provided. A substrate is provided first. After that, an alignment film coating and an alignment treatment are performed to the substrate, and a layer of photoreactive monomer material is coated on the surface of the substrate after the alignment treatment. Thereafter, the layer of photoreactive monomer material is selectively irradiated by UV light in an exposed region, and the layer of photoreactive monomer material in an unexposed region is removed for liquid crystal molecules to have different pretilt angles in the exposed region and the unexposed region.
