きる。Next, a method of manufacturing the liquid crystal panel holding frame according to the present invention will be described. Panel fixing plate 2 and support member 3
When heat-sealing (or the case body) by insert molding, first, the panel fixing plate 2 and the supporting member 3 which are formed in advance are set in a mold. At this time, a space having the shape of the elastic member 6 is formed between the end of the panel fixing plate 2 and the opening 5 of the support member 3. In this space portion, except for a portion contacting the panel fixing plate 2 and the support member 3,
A protrusion is provided so as to protrude from the mold so that the elastic member cannot be densely (uniformly) filled. Next, when the thermoplastic elastomer is injected and filled into the space while being pressurized, the elastic member 6 is formed in the space, and the panel fixing plate 2 and the elastic member 6 are joined by heat fusion, and at the same time, the elastic member 6 is formed. And the support member 3 are joined, and as a result, the elastic member 6
The panel fixing plate 2 and the supporting member 3 are joined via the.
The elastic member 6 is formed in a desired hollow shape by the protrusion. According to this manufacturing method, the panel fixing plate 2
Since the time required for joining the support member 3 and the support member 3 is the time for injection molding the thermoplastic elastomer, the time can be significantly shortened as compared with the case of joining with an adhesive.

In this case, the panel fixing plate and the supporting member may be primarily molded, and then the elastic member may be formed by the secondary molding, which is troublesome to set the panel fixing plate and the supporting member in the mold like insert molding. The manufacturing process can be further simplified because the manufacturing process is unnecessary.

を緩和することができる。When the liquid crystal panel is supported by the liquid crystal panel holding frame formed by the above manufacturing method and the liquid crystal panel is transported or used by being incorporated in the liquid crystal device, the liquid crystal panel fixed to the panel fixing plate is elastic. Since the elastic member is supported by the open structure of the supporting member (or case body) via the member and the elastic member has a hollow shape, it is possible to follow the deformation under load even if it receives vibration or impact. Shock can be mitigated.

Further, in the above embodiment, the case where the panel fixing plate and the support member are heat-sealed by the elastic member has been described, but the present invention is not limited to heat-sealing, and also in the case of filling an adhesive. Can be applied. In other words, by projecting a protrusion that does not adhere to the adhesive to be filled in advance in the space between the panel fixing plate and the support member, and removing the protrusion after curing, even if the space is filled with the adhesive, elasticity is obtained. The member can have a hollow shape, and the same effect as that of the above-described embodiment can be obtained.

特性を向上させることができる。Since the present invention is configured as described above, the elastic member for integrally joining the panel fixing plate and the supporting member or the case body is formed in a hollow shape so that the elastic member has sufficient elasticity. It is possible to provide a liquid crystal panel holding frame that can be obtained and can reduce shock and vibration applied to the liquid crystal panel. In particular, in a small liquid crystal display in which the space of the elastic member is small, the effect of relieving vibration and shock is remarkable. Further, since the panel fixing plate and the supporting member or the case main body are integrally formed by heat fusion through the elastic member, not only the impact and vibration applied to the liquid crystal panel supported by the panel fixing plate are alleviated, but also A liquid crystal panel holding frame that can be manufactured in a short time and can be manufactured at low cost, and a manufacturing method thereof can be provided. In addition, since the panel fixing plate, the supporting member, or the case body and the elastic member are assembled in the injection molding die by insert molding, two-color molding, or multicolor molding, the number of manufacturing processes can be reduced. Particularly in two-color molding or multi-color molding, the panel fixing plate and the supporting member can be molded in the same mold, so that the manufacturing process can be further simplified. The vibration absorbing characteristics can be improved by forming the hollow shape of the elastic member into an oval shape, a round shape, a square shape, a mesh shape, or the like so as to more easily follow a load.
