A test method of an LCD panel is provided to efficiently detect a defect coordinate of the LCD panel by detecting a defect of a signal line using a signal application member, and applying an individual test signal to the defective signal line. A liquid crystal display panel(1) includes a plurality of signal lines(22,32), and a plurality of pads connected to the plurality of signal lines, respectively. A single signal application member(40) contacts at least two of the pads. A test signal is applied to the signal application member to detect a defect of the signal lines. An individual test signal is applied to the defective signal line to defect a defect coordinate. |
