DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for holding a liquid crystal display element used in a display section of an electronic device, such as a small portable terminal device such as a mobile phone, and an electronic device provided with the same.

[0002]

2. Description of the Related Art In recent years, various small portable terminal devices such as portable telephones have been developed. For example, as shown in FIG.
A CD (liquid crystal display) display section 52 is provided.

As shown in FIG. 5, as a schematic configuration, a substrate 53, a holder 54, a light guide plate 55, and an LCD 56 are provided inside a case 50 formed of a base 50A and a cover 50B. Among them, the substrate 53 is fixed to the base 50A,
A holder 54 is fixed to the substrate 53. This substrate 5
3 is fixed to the holder 54 by inserting a pin 54A protruding from the holder 54 into a hole 53A formed on the substrate 53 side. Further, the holder 54 has an LCD
L through a light guide plate 55 for guiding the backlight to
The CD 56 is fixedly held.

Under these circumstances, the rigidity of the case has been reduced and the case has been reduced in thickness. In addition, as the size of the LCD display unit has increased, the weight ratio to the total weight of the LCD display unit has increased. It is conceivable that deformation such as distortion when acting on the part becomes even greater.
