摘要： A color filter layer covering both a thin film transistor and a pixel electrode which are formed on a lower substrate. A portion of the color filter layer positioned on the thin film transistor serves a protection layer of the thin film transistor and the other portion of the color filter layer serves a conventional color filter layer which were conventionally formed on an upper substrate opposite to the lower substrate. Therefore, the process number for the LCD is decreased and thus the manufacturing cost of the LCD is reduced.
