  • Method of fabricating thin liquid crystal display device
    Patent number: 8512580
    Abstract: A method of fabricating a thin liquid crystal display device including a glass substrate having a flat surface. The method includes etching at least one surface of a liquid crystal display, panel, and grinding the surface of the liquid crystal display panel so as to planarize the etched liquid crystal display panel.

  • Manufacturing process of liquid crystal cell for a small size liquid crystal display device
    Patent number: 6731368
    Abstract: In the typical LCD device, the ON/OFF inspection is performed by unit cell. However, in the case of the small size LCD device, since the liquid crystal cell substrate has many unit cells, the total inspection time is too long and the long handling time contributes to increasing the number of inferior cells. To solve these problems, the ON/OFF inspection of the liquid crystal cell for the small size LCD device having many unit cells is simultaneously performed for the entire liquid crystal cell substrate before cutting into the unit cells. Thus, the number of damaged cells during the inspection process and the process time can be reduced, and the yield can increase.
