Zusammenfassung:PURPOSE: An apparatus for testing a liquid crystal display panel is provided to prevent neighboring fine-pitch lines from erroneously coming into contact with each other so as to accurately test a liquid crystal display panel. CONSTITUTION: An apparatus for testing a liquid crystal display panel is constructed in a manner that an output side(24a) of a tape carrier package(24) having a fine pitch is fixed and connected to a gate pad of a TFT substrate(22), and an input side(24b) of the tape carrier package is connected to a test substrate(26), so as to test the TFT substrate. The TFT substrate and the output side of the tape carrier package are connected to each other through an outer lead board. A flexible printed circuit(28) is interposed between the input side of the tape carrier package and the test substrate.
