  • Patent number: 6496234
    Abstract: A method of manufacturing a liquid crystal panel prevents the introduction of static electricity from the exterior of a liquid crystal panel. According to the method, edges of a lower glass substrate on which a liquid crystal material layer and an upper glass substrate are disposed are dipped into an etchant. At this time, the ends of the test electrodes formed on the lower glass substrate are removed. The ends of the test electrodes are removed, and consequently an introduction path of stripe-shaped defect is not generated within the liquid crystal panel. Also, the yield of the liquid crystal panel is greatly improved.

  • Patent number: 6204081
    Abstract: A method of manufacturing a substrate of an LCD prevents defective patterning of pixel electrodes and improves an aperture ratio of pixels by simplifying the steps of manufacturing a substrate of an LCD. A protection layer is formed on a substrate and the protection layer includes a light developable organic(BCB) layer which is patterned directly by exposing using a mask instead of patterning with a photo resist. The portion of the light developable organic layer remaining on the bottom part of contact holes after patterning is etched using a gate insulating layer. The etching process using the gate insulating layer is performed partially in order to expose the surface of the gate pad by using a plasma gas having about 85% CF4 and about 15% O2.
