发明名称 LIQUID CRYSTAL DISPLAY DEVICE AND ITS MANUFACTURING METHOD
摘要 PROBLEM TO BE SOLVED: To provide a normally white mode liquid crystal display device and its manufacturing method which make it secure and easy to change a bright point (a defective pixel always making a white display) into a black dot (conversion into a pixel always making a black display). SOLUTION: When the alignment film in a bright point area 51 (pixel opening regarding a bright point) is irradiated with laser light, a scan with the laser light is made in a rubbing direction. Consequently, notches 61 are arrayed in the nearly entire bright point area 51 at nearly equal intervals. Or a vacuum bubble is formed by laser light irradiation before the scan with the laser light is made. In this case, the scan with the laser light is made while the nearly entire bright point area 51 is covered with the vacuum bubble.
