Abstract

A liquid crystal panel 11 includes a pair of substrates 18, 19, liquid crystal 20 disposed between the substrates 18, 19, and alignment films 30, 36 provided on the opposed surfaces of the substrates 18, 19. After formation of the alignment film 30 or 36 is completed in a manufacturing process, it is checked by an inspection process whether a pinhole H is formed on the alignment film 30, 36, and further the position of the pinhole H is detected. Thereafter, an alignment film repair filler 50 is applied to the pinhole H by a repair process, so that the pinhole H is repaired.
