Abstract
The present disclosure provides a liquid crystal display apparatus having a reduced area of a dark line occurring when light is transmitted through a pixel region, and excellent transmittance of light and image quality. The liquid crystal display apparatus includes: two substrates each of which has an electrode and a photo alignment film sequentially formed on one surface and one surfaces of which face to each other; a liquid crystal layer which includes a vertical alignment type liquid crystal material, and is interposed between both photo alignment films; a plurality of pixel regions formed on the substrates in a matrix in a planar direction of the substrates; at least two liquid crystal domains which are included in each pixel region, and have different standard alignment directions defined by the photo alignment films; main slits which are formed in regions corresponding to each liquid crystal domain of one electrode, and extend parallel to each standard alignment direction, and sub slits extending between two liquid crystal domains, which are arranged in one direction, in the other direction orthogonal to the one direction. The sub slit has a width of a width or more of the main slit.
