INSPECTION DEVICE OF LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: An inspection device of an LCD device is provided to configure a TG(Transmission Gate) signal applying pad for applying a TG driving signal on the same TFT substrate as an OS(Open Short) pad, and to connect a channel terminal with data lines when the data lines are inspected as being inferior, thereby transmitting a test signal up to the OS pad. CONSTITUTION: A TFT substrate(200) forms a pixel array. A PCB supplies an image signal to the TFT substrate(200). Plural driving ICs(210) receive the image signal from the PCB. A flexible cable film electrically connects the PCB with the driving ICs(210). The TFT substrate(200) is configured by a COG(Chip On Glass) method for directly configuring the driving ICs(210) on the TFT substrate(200). Plural gate lines are arrayed on the TFT substrate(200) in width direction. Plural data lines(DL) are arrayed along a longitudinal direction of the TFT substrate(200) to cross the gate lines.
