ABSTRACT:
An LCD test device and a test process thereof are disclosed, in which a defect of an LCD panel is exactly identified through exact electrical connection between an LCD panel and a probe unit. The LCD test device includes a work table on which an LCD panel is mounted, a clamping unit on the work table, clamping a top surface of an edge of the LCD panel mounted on the work table, a probe unit electrically connected with a pad of the LCD panel fixed to the work table by the clamping unit, and a back light unit supplying light to the LCD panel fixed to the work table. Accordingly, since the defect of the LCD panel can be tested exactly, reliability of the test is improved, and it is possible to prevent yield and the cost from being reduced in advance.
