PURPOSE: To test operation without soldering by using terminals of a liquid crystal display where TAB tapes are connected and the dedicated test jig where terminals of a printed wiring board for connection are made to abut.
CONSTITUTION: A panel to be tested where the TAB tapes 2 are connected and fixed is prepared as a liquid crystal display panel 1. Then the panel 1 is incorporated in the internal edge of a support base 200. Then a connection adjusting base 210 is fitted and adjusted by using position adjusting mechanism 211 so that the respective corresponding terminals 20 of the TAB tapes 2 are aligned with and put on the connection terminals 30 of the printed wiring board 3 for connection which are arranged at the upper edge. Then a pressure application base 220 is mounted gently and both terminals are connected electrically. Consequently, connections between both the terminals can be tested without soldering and even if a defect is generated, the replacement is easy and performed in a short period of time.
