Abstract

A probe unit is provided. The probe unit for testing a liquid crystal panel includes a body block configured to have a bottom surface to which a tab IC film for use in the liquid crystal panel is attached while one end of the tab IC film is folded, and allow metal lines formed on the tab IC film to be in one-to-one contact with electrode lines formed on the liquid crystal panel; and a flexible printed circuit board configured to be electrically connected to the other end of the tab IC film and provide a test signal to the liquid crystal panel through the tab IC film.
