  • Patent number: 8097480
    Abstract: A method of making a liquid crystal display having a display region and a non-display region, the method comprises forming a thin film transistor (“TFT”) having a drain electrode on an insulating substrate, forming an inorganic layer and an organic insulating layer sequentially on the TFT, forming an organic insulating layer pattern, by patterning the organic insulating layer, comprising a first organic layer hole to expose the inorganic layer on the drain electrode and a second organic layer hole formed along a circumference of the display region where the organic insulating layer is partially removed, removing the inorganic layer exposed through the first organic layer hole and the organic insulating layer remaining in the second organic layer hole, and forming a sealant in the second organic hole. The present invention thus provides a method of making an LCD to prevent a color filter substrate separating from a TFT substrate using fewer masks.
