Abstract:
Provided is a liquid crystal display apparatus which has a reduced area of a dark line generated when light is transmitted through a pixel region, and excellent transmittance of light and image quality. The liquid crystal display apparatus has two substrates which respectively have an electrode and a photo alignment film sequentially formed on respective one surfaces, and are disposed so that the one surfaces thereof face to each other, wherein a liquid crystal layer including a vertical alignment type liquid crystal material is interposed between the photo alignment films; a plurality of pixel regions formed on the substrate in a matrix shape in a plane direction of the substrate; and at least two liquid crystal domains which are included in each pixel region, and have standard alignment directions different from each other defined by the photo alignment films. One electrode 2 has oblique slits 21 extending parallel to each standard alignment direction at the region corresponding to each liquid crystal domain. In addition, longitudinal slits 22 and 22 extending in the column direction are provided at the boundary portions of the liquid crystal domains arranged in the row direction, and lateral slits 23 and 23 extending in the row direction at the boundary portions of the liquid crystal domains arranged in the column direction. The longitudinal slits 22 and the lateral slits 23 are independent from the oblique slits 21 without continuing to the oblique slits 21.
