Abstract: PURPOSE: An etching point detective window of liquid crystal display and etching point detecting method by using the same are provided to detect an etching completion point accurately by using a dummy pattern of the same thickness and material as a real pattern. CONSTITUTION: A dummy pattern(48) has the same thickness and material as a real pattern, and is arranged under an EPD(etching point detective) window(52) on the non-display region of a substrate(18). In process of etching time, a gate insulator(22) is exposed by the complete removal of an organic passivation(46) inside the EPD window(52) and a real pattern window(53). At this time, the density of exhausted SiF4 gas is strikingly reduced or isn't exhausted any more. Therefore, it is possible to detect the exposure time of the gate insulator(22) by the EPD signal proportional to the variation of SiF4 gas. In process of etching time, the dummy pattern(48) and a pad(2a) of a gate line are exposed. At this time, the density of SiF4 gas is strikingly reduced. Therefore, it is possible to detect the exposure time of the dummy pattern(48) and the pad(2a) of the gate line by the EPD signal. The etching completion point of the real pattern window(53) is identical to the etching completion point of the EPD window(52).
