2. Description of the Related Art In recent years, transmissive or semi-transmissive liquid crystal displays have been widely used for display devices such as word processors and personal computers. In such a liquid crystal display, illumination is usually arranged on the back surface of the liquid crystal display. For illumination of the back surface, a fluorescent lamp or a discharge type of a cold cathode tube is usually used as a light source. As a lighting method, generally, a light source is arranged directly below the back surface of the liquid crystal display section, and a light source is arranged in a lateral direction of the liquid crystal display section, and a planar light emitting illumination is created using a light guide plate such as acrylic. Is known. The latter is called the side light method.

In the latter structure of the sidelight system, a fluorescent lamp or a cold cathode tube is arranged beside a light guide plate made of acrylic or the like, and the surrounding area is covered with a metal holder such as aluminum. In addition, the light guide plate has a diffusion sheet on its upper surface.
The bottom surface of each of the sheets is coated with a reflection sheet. Then, from both ends of the fluorescent lamp or the cold cathode tube, the lead wire (hard

The present invention includes a light guide plate and
A sidelight device comprising at least a light source provided in proximity to one side surface of the light guide plate, a light source holder provided so as to cover the light source, and a lead wire drawn from the light source. The lead wire is a sidelight device fixed to the light source holder by a clip cut and raised integrally.

According to the present invention, since the lead wire is fixed by the rubber cap and the clip of the holder, the lead wire is not broken even when the lead wire is connected or an intentional force is applied. Don't worry, it won't cause a bad connection. Therefore, workability can be improved, and when used in a liquid crystal display,
The defects caused by the sidelight device are reduced.

A sidelight device according to the present invention is constructed as shown in FIG. 1. Reference numeral 1 in the figure is a light guide plate made of acrylic or the like, and a diffusion sheet 4 is provided on the upper surface of the light guide plate 1 and a lower surface thereof. Reflective sheets 5 are applied to each. A light source 2 such as a fluorescent lamp or a cold cathode tube is provided near one side surface of the light guide plate 1 and lead wires 6 are drawn from both ends of the light source 2. In this case, the lead wire 6 is pulled out by a rubber cap 7 made of silicon or the like.

The light source 2 is covered with a light source holder-3 made of metal such as aluminum. The light source holder-3 serves to collect light from the light source 2 to the light guide plate 1 and to prevent damage to the light source 2. Further, a plurality of clips 8 are cut and raised integrally with the light source holder-3,
The lead wire 6 is pressed by bending the clip 8. That is, in the present invention, the lead wire 6 is fixed to the light source holder-3 by the clip 8. Therefore, when an unnecessary force is applied to the lead wire 6, it is possible to eliminate the lighting failure due to the disconnection or the contact failure.
