LIQUID CRYSTAL DISPLAY PANEL, METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY PANEL, AND PHOTO-ALIGNMENT PROCESSING DEVICE

摘要

The disclosure provides a liquid crystal display panel having excellent light utilization efficiency and display uniformity. The disclosure is a liquid crystal display panel including, in the following order, a first substrate including a first photo-alignment film, a liquid crystal layer, and a second substrate including a second photo-alignment film. Given an alignment vector in which a major axis edge of the liquid crystal molecules closer to the first substrate is set to a start point and a major axis edge of the liquid crystal molecules closer to the second substrate is set to an end point, the first and second photo-alignment films are subjected to an alignment process such that first to fourth domains are formed in a display unit region overlapping with one of the plurality of pixel electrodes in a longitudinal direction of the display unit region. In a plan view, the alignment vectors of the first and second domains are mutually perpendicular with the end points facing each other, the alignment vectors of the second and third domains are mutually parallel with the start points facing each other, and the alignment vectors of the third and fourth domains are mutually perpendicular with the end points facing each other.
