Zusammenfassung:	The present invention relates to an LCD (Liquid Crystal Display) test system, and more particularly to an in-line LCD test system capable of promptly and accurately testing LCDs. There is provided an LCD test system including a main frame, an index stage located adjacent to the main frame and having a stacker for supplying a plurality of LCD cassettes, a pre-alinger for aligning the LCD supplied from the stacker of the index stage; a carrier for transferring the aligned LCD so as to test the LCD, and a work table unit for setting such that the LCD transferred by the carrier is tested. According the LCD test system thus constructed, the LCD to be tested is automatically aligned, transferred and electrically contacts to the probe pins by the pre-aligner, the carrier and the work table unit, respectively. A series of such processes reduces the time required to test the LCD and increases in an test accuracy.
