Description of the invention (i) [Technical field to which the invention belongs] (Please read the precautions on the back before filling out this page) This invention relates to edge-light type surface light source devices and liquid crystal display devices. In particular, The present invention relates to a surface light source device and a liquid crystal display device in which a frame for accommodating each component constituting these devices is improved. [Related Technology] It is known that a liquid crystal display screen that illuminates a liquid crystal display device with an edge-light type surface light source device. A general edge-light type surface light source device includes a light guide plate and a primary light source that supplies primary light to the light guide plate. A typical primary light source is a rod-shaped fluorescent lamp (cold-cathode tube). The primary light source is arranged along the incident end face of the light guide plate. Most of the side-lighting type surface light source devices include plate members such as a light collecting sheet, a diffusion sheet, and a protective sheet in addition to a light guide plate and a primary light source. These components are housed in a predetermined frame in a frame to constitute an edge-light type surface light source device. If a unit containing a liquid crystal display is added, a liquid crystal display device is constituted. Liquid crystal display devices using these side-light type surface light source devices have the advantage of being printed by consumer cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, resulting in the device being too thick, and they are mostly used in portable personal computer displays. # In recent years, the demand for thinner and lighter weight of these portable devices, including integrated devices including displays, has increased. For this reason, the liquid day-to-day display devices constituting the display, especially the side-light type surface light source devices for liquid crystal display screen lighting, are designed to be lighter and thinner, and the efforts to reduce thickness have not been interrupted. A cross-sectional view of a typical structure of an edge-light type surface light source device suitable for a liquid crystal display device is shown in FIG. 10. In addition, the frame plan used here i paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 public love) ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- PRINTED BY EMPLOYEE CONSUMER COOPERATION COORDINATE (2) As shown in Figure 11. Referring to Fig. 10, the side-light type surface light source device 60 includes: a square-shaped reflecting sheet 62; a light guide plate 63; a diffusion sheet 64; two light collecting sheets 65 and 66; and a retaining sheet 67. These components are stacked and housed in a frame 61 made of a synthetic resin such as polycarbonate. Next to the light guide plate 63 is a rod-shaped light source 68 such as a cold-cathode tube as a primary light source. A light collecting sheet 65 and 66 are used to orient the light emitted from the light guide plate 63 obliquely and preferentially. In order to make more illumination light to the front direction (upper in Figure 10). In this example, the direction in which the light collecting plates 65 and 66 are formed is a direct parent to each other. Again. A liquid crystal display screen 70 in which a liquid crystal display screen unit is placed on top of the protective sheet 67 constitutes a liquid crystal display device. When the rod-shaped light source 68 is lit, light is introduced from the side of the light guide plate 63 to the inside. The light is then transmitted in the light guide plate 63 and gradually emerges from the surface (the exit surface) of the light guide plate 63. The emitted light is supplied to the liquid crystal display screen 70 through the diffusion sheet 64, the light collection sheets 65, 66, and the protective sheet 67. In order to reduce the weight and thickness of these side-light type surface light source devices 60, a frame as shown in Fig. 11 may be used. The frame 61 is a molded body that is one of injection molding applications, and has a thin and thin wall and a complicated shape. For this reason, the manufacturing of molds used for molding requires high technology and expensive expenses, resulting in a high cost of the device 60. Sometimes it is difficult for the mold to make the desired shaped body. The solution to these situations is to prepare a plastic bracket with a mounting part for external fixing, and fix it to the side of the light guide plate with an adhesive material such as double-sided tape. This technique can be found in (Japanese Patent Application Laid-Open No. 1〇 _96921 ^ Paper size is applicable to China National Standard (CNS) A4 specification (210 X 297 mm) 310957 i—ί — ---- --------- Order --------- I is _ W (Please read the precautions on the back before filling out this page) II n-507092 A7 V.
