ABSTRACT:
A pixel unit having a display area is provided. The pixel unit includes a first substrate, a second substrate, a liquid crystal layer, and at least one ultraviolet light (UV) absorption pattern. The second substrate is disposed in parallel to the first substrate, and the liquid crystal layer is disposed between the first substrate and the second substrate. The UV absorption pattern is disposed between the first substrate and the second substrate. A part of the display area overlaps the UV absorption pattern to define at least one first alignment area, while the part of the display area which does not overlap the UV absorption pattern defines at least one second alignment area. The liquid crystal molecules of the liquid crystal layer present different pre-tilt angles in the first alignment area and the second alignment area.
