An electric contact apparatus has a flexible contact sheet 13. A plurality of conductive elements 14 are provided on a front side of the flexible contact sheet 13 and are arranged in parallel with each other along the direction of arrangement of electrodes 4 arranged on an insulating substrate 2 of a liquid crystal display panel 1 so as to be brought into contact with the electrodes 4, respectively. An internally sealed elastic tube 17 is supported in a groove 18 formed on one side of a pressing plate 11 and extends along the direction of arrangement of the conductive elements 14 so as to press a part of each contact region between the conductive elements 14 and the electrodes 4.

Electric contact apparatus for inspecting a liquid crystal display panel

A display panel inspection socket has a socket body for holding a display panel having electrode terminals arranged on at least one side of the surface of an insulating base plate. Contacts are formed on contact films attached to the socket body. An elastic supporting member extends along a direction of arrangement of the electrode terminals and supporting the back surfaces of the contact films is attached to the socket body. A clip member is attached on the side of the socket body so as to grip the socket body and the insulating base plate of the display panel. When the clip member is moved from a releasing position to a pressing position, the back surface of the insulating base plate of the display panel is pressed by the clip member. This moves the electrode terminals of the display panel and the contacts on the contact films are electrically connected under a required contact pressure.
