The J light guide (3 1 0) contains a light source that is not shown on the opposite side of the LCD panel (1 G 0). The light source is turned by a tubular light source (3 2). The light selection is a printed pattern for adjusting the milky brightness of the liquid crystal panel (100). Instead of this printed pattern, a light scattering groove may be integrally formed. In addition, the light guide plate (3 1 0) abuts 2 The edges (3 1 1) and (313) form a groove, and an approximately L-shaped tubular light source (3 2 0) may be accommodated in the groove. In this case, it will be formed on the light guide plate (3 1 0 This paper size applies China National Standard (CNS) A4 Specification < 210x297 mm) _ 8-4 5 5 7 2 8 A7 B7 _ 5. The light introduction surface of the groove of the invention description (6)) is defined as the end edge. This resin skeleton (3 3 0) can be formed by holding one of the light guide plates (3 1 0), but it can also be formed by a split type. In addition, the resin skeleton (330) includes support portions for supporting the aforementioned TABs (150) and (160) on a side different from the receiving groove (333) for receiving the tubular light source (320). (351), (353). In addition, one end of the L-shaped tubular light source (3 2 0) is connected to the high-voltage side power wiring (3 2 3) and extends outward, and the other end is connected to the ground power wiring (3 2 5) and is housed in The L-shaped tubular light source (3 2 0>) is formed in the wiring receiving groove (3 3 3) of the resin skeleton (3 3 0), and the tubular light source (3 2 0) faces outward through the resin skeleton (330). It extends in the direction. According to the liquid crystal display device (1) configured as described above, since the L-shaped tubular light source (3 2 0) is used, the light amount of the light source can be increased, thereby achieving high contrast. In addition, each TAB (150) '(160), L-shaped tubular light source (320), power wiring (325), (3 2 3) are not close to each other. Therefore, the surface light source device (the employee of the Central Standards Bureau of the Ministry of Economic Affairs) Printed by the Consumer's Cooperative (please read the precautions on the back before filling out this page) 3 0 0) The image of noise can be fully reduced, which can display high-quality display images. Moreover, the tube light source ( 3 2 0) is also exchanged for the resin skeleton (3 3 G) Removal and fitting of the lampshade (350) can be easily achieved. In this embodiment, since the resin frame (330) is provided with a fitting protrusion (371), the lampshade (350) is made of paper. Applicable to China National Standard (CNS) A4 (210X297mm)-9-455728 A7 B7 V. Description of the invention (7) It is formed by fitting holes (3 5 3), so it is fixed with screws or the like Compared with the method, the number of parts can be reduced. In addition, especially in this embodiment, the receiving groove (331) and the lampshade (350) corresponding to the resin skeleton (330) of the tubular light source (320) are used for the light guide plate, respectively. (310) Because it is formed in the shape of an arc that collects light from the light source, a reflective film is not required, and therefore the exchange of the tubular light source is easier. In this embodiment, its structure is tied in the receiving groove of the resin skeleton (330). The L-shaped tubular light source (3 2 0) is housed, but the L-shaped tubular light source (3 2 0) is housed in the lampshade (3 50) and can be fixed to 0. Furthermore, as shown in FIG. 4, the lamp cover (3 50) Pre-formed and fixed L-shaped tubular light source (3 2 G) Light tube containment ditch (printed by the Consumer Cooperatives of the Central Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) 3 5 5), along with this light tube containment ditch (3 5 5 ) If the wiring receiving groove (357) is formed in advance, the lamp cover (350) and the L-shaped tubular light source (320) can be integrated. Therefore, as long as the resin frame (330) is removed, The fitting projection (37 1) and the fitting hole (3 5 3) of the lamp cover (3 50) can remove the integrated tubular light source (3 2 Q) from the lamp cover (3 50). In addition, only the tube light source (320) arranged in the lampshade (350) is exchanged, and the fitting protrusions are fitted to the resin frame (330) to facilitate the exchange of parts. In the above-mentioned embodiment, it is used. The drive circuit portion is configured by mounting a TAB made of a driver IC on a flexible substrate, but the following configuration may be used instead. This paper size applies the Chinese National Standard (CNS) A4 specification {210X297 mm) _ 10-455728 A7 B7 V. Description of the invention (8) The driving circuit (150) (160) will be driven as shown in Figure 5, (please first (Please read the notes on the back and fill in this page)) It can also be integrated in the manufacturing process of the array substrate (110). That is, the driving circuit portion (150) (160) may be formed using an n-type or P-type TFT having the same structure as the n-type TFT (107) connected to the pixel electrode. In this case, it is preferable to use polycrystalline silicon or single crystal silicon as the active layer in order to sufficiently ensure the operating characteristics. Further, as shown in FIG. 6, a plurality of drives 1C (170) (180) may be directly mounted on the glass substrate (1 0 1).
