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.
Claims23
In a process of manufacturing a display panel in which liquid crystal is disposed between a pair of substrates arranged opposite to each other and an alignment film is provided on an opposed surface of said substrates, a display panel manufacturing method comprising:
- inspecting said alignment film for a presence of a film defective part by an inspection process;
- detecting a position of said film defective part by a position detection process;
- and
- applying an alignment film repair filler to at least a portion of said film defective part by a repair process, so as to repair said film defective part.
A display panel manufacturing apparatus for a display panel in which liquid crystal is disposed between a pair of substrates arranged opposite to each other and an alignment film is provided on an opposed surface of said substrates, said display panel manufacturing apparatus comprising:
- an inspection device arranged to inspect said alignment film for a presence of a film defective part;
- a position detection device arranged to detect a position of said film defective part;
- and
- a filler application device arranged to apply an alignment film repair filler to at least a portion of said film defective part so as to repair said film defective part.
A display panel comprising:
- a pair of substrates arranged opposite to each other;
- liquid crystal disposed between said substrates;
- an alignment film provided on an opposed surface of said substrates;
- and
- a repair part in which an alignment film repair filler is applied to at least a portion of a film defective part developed on said alignment film.
