Description

  The present invention is suitably used for thin information devices such as portable telephones and portable information terminals using a liquid crystal display as a display surface, and in particular, structural reinforcement during assembly of a thin liquid crystal display (LCD), The present invention relates to a portable information device capable of preventing cracking and stabilizing quality.

Conventionally, in thin information devices such as portable telephones and portable information terminals, thin liquid crystal displays (LCDs) having advantages such as light weight, color display, low voltage driving, and low power consumption have been widely used. (For example, refer patent document 1 etc.).
This thin LCD has a structure in which a liquid crystal is sandwiched between a pair of glass substrates together with a spacer. However, due to intensifying competition for thinning and an increase in the size of LCDs in recent years, the thickness of the glass substrate is also thin in thin LCDs. The rigidity of the thin LCD itself is lower than the conventional one. Therefore, in the assembly process of the production line, the glass substrate may be inadvertently broken when the worker assembles, and the glass substrate may be broken when the user is handling after shipping the product. .

  However, in the above-described conventional mobile phone 1, the length of the locking claw 4 a on the side surface of the resin frame 4 is set to the thickness of the metal frame 5 for the convenience of locking to the flat portion 5 a of the metal frame 5. Since 4a is involved, there is only a length to which a gap for moving is added.

  In this case, when the resin frame 4 to which the thin LCD 3 is pasted and fixed is fitted into the metal frame 5, the bending allowance of the locking claws 4a formed on the side surface of the resin frame 4 is short. When the claw 4a is locked to the flat portion 5a of the metal frame 5, a considerable amount of pushing force is required, so that an impact force or load is momentarily applied to the thin LCD 3 at the time of locking. As a result, in the assembly process of the production line, the glass substrate is inadvertently broken when an operator assembles, and the glass substrate is broken when the user handles it after shipping the product. .
