PATTERNING PHASE DIFFERENCE PLATE, PRODUCTION METHOD FOR PATTERNING PHASE DIFFERENCE PLATE, 2D/3D SWITCHING TYPE LIQUID CRYSTAL DISPLAY PANEL, AND 2D/3D SWITCHING TYPE LIQUID CRYSTAL DISPLAY UNIT
PATTERNING PHASE DIFFERENCE PLATE, PRODUCTION METHOD FOR PATTERNING PHASE DIFFERENCE PLATE, 2D/3D SWITCHING TYPE LIQUID CRYSTAL DISPLAY PANEL, AND 2D/3D SWITCHING TYPE LIQUID CRYSTAL DISPLAY UNIT
A first rubbing is performed on the entire surface of an alignment film (22) formed on a substrate (21), and then a mask unit (51a) for masking a first area and an alignment mark forming area by means of a resist layer (51) is formed on the alignment film (22). After performing a second rubbing onto the alignment film (22) through the mask unit (51a), the mask unit (51a) is removed, a liquid crystal layer (23) is formed on the removed portion, and the alignment mark is formed to provide an area different in optical action between its forming area and the surrounding area. Accordingly, it is possible to produce a substrate (21) provided with an alignment mark formed in a location contacting a liquid crystal layer (23) without increasing processing steps.
