Abstract
A method for manufacturing a liquid crystal display panel is provided. A photo-alignment layer is formed on a first substrate. Patterned pixel electrodes including intersected electrodes and stripe electrodes are formed on a second substrate. A liquid crystal layer is formed between the photo-alignment layer and the patterned pixel electrodes. Each intersected electrode has a first directional portion and a second directional portion interlacing thereto. The stripe electrodes with silts connect the first and/or the second directional portions. When an electric field between the first and the second substrates is substantially zero, liquid crystal molecules near the photo-alignment layer are arranged at a pre-tilt angle, while those disposed at another side near the second substrate are substantially perpendicular to the second substrate. As the liquid crystal layer is driven, the liquid crystal molecules of the liquid crystal layer are substantially arranged along an extending direction of the slits.
