[0001]

TECHNICAL FIELD The present invention relates to a liquid crystal display panel,
A contact film for an electrical component inspection socket, which is suitable for an electrical component inspection socket used for inspection such as display quality of display panels such as electroluminescence panels and plasma display panels, or inspection for semiconductor integrated circuit (IC) operation confirmation, etc. Regarding mounting structure.

[0002]

2. Description of the Related Art Generally, in a manufacturing process of a display panel such as an electric component, for example, a liquid crystal display panel, an electroluminescence panel, a plasma display panel or the like, a display panel before connection of peripheral circuits such as a driving IC tab is required. Inspections such as display defects and display quality are performed.To inspect such display defects and display quality, the display panel is attached to the display panel inspection socket, which is an electrical component inspection socket, and the display panel is turned on. It is done by letting. And to turn on the display panel,
It is necessary to use a contact member that electrically contacts the electrode terminals arranged and formed on the substrate of the display panel. Therefore, conventionally, a display panel inspection socket has a needle-shaped or wire-shaped probe or a resin film substrate as a contact member for electrically contacting an electrode terminal formed on the display panel. Although a contact film having a child pattern is used, due to the high density and fine pitch of the electrode terminals, it is easy to handle when making contact with the electrode terminals, from the viewpoint of manufacturing cost, etc. A contact film having a contact pattern capable of contacting an electrode terminal tends to be adopted. This contact film is fixed to a film mounting plate formed of an insulating substrate such as glass that is slidably arranged in the socket body of the display panel inspection socket.

FIGS. 9 and 10 show a general contact film mounting structure of a conventional display panel inspection socket as an electric component inspection socket. On the film mounting plate 3 which is an insulating substrate such as a long glass which is slidably arranged on the socket body (not shown) of the display panel inspection socket by the double-sided tape 2A as the fixing means 2. , Each contact film 1
The contactor pattern (not shown) formed on the upper surface (front surface) is fixed at a predetermined interval so that the pitch accuracy is about 50 to 100 μm. Further, each contact film 1 is formed so that at least one end portion in the direction orthogonal to the longitudinal direction of the film mounting plate 3 projects from the film mounting plate 3, and is formed on the upper end portion of this projecting portion. The exposed portion of the contact pattern (not shown) is brought into contact with the electrode terminal of the display panel (not shown).

[0004]

However, in the contact film mounting structure of the display panel inspection socket as the conventional electric component inspection socket described above, a plurality of contact films 1 are attached to the film mounting plate 3 by the double-sided tape 2A. Since it is fixed, the film mounting plate 3 is slid along the longitudinal direction of the contact films 1 when the display panel as an electric component is mounted in the display panel inspection socket and the display panel is illuminated. When the position adjusting operation of bringing the contact pattern of the above into contact with the electrode terminal of the display panel is repeated, at least a part of the contact film 1 moves in the longitudinal direction of the film mounting plate 3, and each contact fixed to the film mounting plate 3 is moved. The position of the film 1 is misaligned, and the contact film 1 mounting accuracy As a result, the pitch accuracy of the contact pattern between the contact films is distorted, and part of the contact pattern does not contact the electrode terminals of the display panel. There is a problem that the inspection cannot be properly performed for a long period of time.

Therefore, as a contact film mounting structure of a display panel inspection socket for coping with such a problem, as shown in FIGS. 11 and 12, a plurality of contact films 1 are attached to a film mounting plate by a double-sided tape 2A. After fixing to No. 3, the upper surface of the contact film 1 and the film mounting plate 3 excluding the portions which come into contact with the electrode terminals of the display panel shown in the shaded area in FIG. Adhesive 2B
Although a mounting structure in which the contact films 1 are fixed by means of such a mounting structure is conceivable, it is possible to prevent displacement of the positions of the contact films 1 fixed to the film mounting plate 3 due to repeated position adjusting operations, but the inspection socket. When the test socket is used for inspection such as aging of the display panel, if the inspection socket is exposed to an environmental temperature of up to 80 ° C,
Each contact film 1 fixed to the film mounting plate 3 slightly moves, the distance between the contact films 1 fixed to the film mounting plate 3 is displaced, and the pitch accuracy of the contact pattern of each contact film 1 is deviated. However, there is a problem that a part of the contact pattern does not contact the electrode terminal of the display panel, and as a result, the display panel as an electric component cannot be properly inspected.

Therefore, even when the contact operation of the contact pattern of the contact film of the display panel inspection socket and the electrode terminal of the display panel is repeated, or when the display panel inspection socket is used for inspection such as aging of the display panel. There is a demand for a contact film mounting structure for a display panel inspection socket that can prevent the contact film 1 fixed to the film mounting plate 3 from being displaced.

The present invention has been made in view of these points, and even when the contact pattern of each contact film and the electrode terminal of the display panel are repeatedly used for contact, or when used for inspection such as aging, An object of the present invention is to provide a contact film mounting structure for an electrical component inspection socket, which is capable of preventing a gap between the contact films fixed to the film mounting plate.
