2. Description of the Related Art Generally, in a manufacturing process of a liquid crystal display panel or the like, a display panel before connection of peripheral circuits such as a driving IC tab is inspected for display defects and display quality. In that case, in order to light the display panel, electrode terminals (electrode terminals) arranged and formed on the substrate of the display panel
It is necessary to contact the contact member with. Therefore, conventionally, a needle-shaped or wire-shaped probe or a flexible wiring board formed by forming a contactor pattern on a resin film substrate has been used as a contact member with an electrode terminal. With higher density and finer pitch, flexible wiring boards tend to be adopted from the viewpoint of reliability of contact with electrode terminals, ease of handling, manufacturing cost, and the like.

Further, the present applicant has filed Japanese Patent Application No. 7-53555.
As disclosed in Japanese Patent Application No. 7-100579 and Japanese Patent Application No. 7-100579, a display panel inspection socket capable of performing an inspection such as display quality of a display panel and an aging test for inspecting durability of the display panel at high temperature is proposed. This display panel inspection socket is provided with a substantially rectangular socket body having a panel positioning means for holding a substrate of the display panel, and the socket body is arranged along the arrangement direction of the electrode terminals on the substrate of the display panel. An extending film mounting plate is provided so that its position can be adjusted in the longitudinal direction through position adjusting means, and a flexible wiring board having a contact for contacting an electrode terminal of a display panel is mounted on the film mounting plate. Has been. Therefore, by adjusting the position of the end portion of the film mounting plate with the position adjusting means, the electrode terminals on the substrate of the display panel on the socket body and the contacts on the flexible wiring board mounted on the film mounting plate are aligned. Then, the display panel can be fixed to the socket body by pressing the substrate of the display panel from behind the electrode terminal with the panel pressing member provided in the socket body, and the electrode terminal and The contact element can be kept in contact with a required contact pressure.

[0004]

In the above-mentioned conventional display panel inspection socket, the position adjusting means for adjusting the position of the end of the film mounting plate presses one end of the film mounting plate in the longitudinal direction. Since the urging spring and the adjusting member that comes into contact with the other end of the film mounting plate against the spring force are included, a compressive load acts on both ends of the film mounting plate in the longitudinal direction, and It is conceivable that the load causes the film mounting plate to bend, which adversely affects the alignment accuracy and durability of the contacts of the flexible wiring board mounted on the film mounting plate and the electrode terminals on the display panel. Further, in the liquid crystal display panel, it is common to arrange the electrode terminals along the two sides and the three sides of the substrate. However, similar to the conventional display panel inspection socket described above, the film mounting plate Since it is necessary to dispose the biasing spring and the adjusting member of the position adjusting means at the corners of the socket body on one end side and the corners of the socket body on the other end side of the film mounting plate, respectively. If an urging spring or an adjusting member for adjusting the position of the other film mounting plate is to be arranged at the corner of the socket, there arises a problem that the socket body becomes large.

Therefore, an object of the present invention is to provide a display panel inspection socket which can be easily applied to a display panel having electrode terminals arranged on two or three sides of a substrate. .
