  • Method for the correction of a defect in a liquid crystal display device
    Patent number: 5926246
    Abstract: Laser beam irradiation spots are formed in a delta arrangement on a defective pixel present in a liquid crystal panel so that liquid crystal molecules in areas surrounding the irradiation spots are oriented vertically. Alternatively, an aligning film in a defective pixel is irradiated with a laser to form minute grooves in a different direction than the rubbing direction of the aligning film, whereby the orientation of the liquid crystal is changed so that the liquid crystal between the aligning films is no longer twisted. Thereby, a defective pixel present in a liquid crystal display panel can be made inconspicuous, and as a result, degradation of the display quality of the liquid crystal display device after correction can be prevented.
