[Prior Art] A liquid crystal module can be constructed by mounting a frame, a frame, a light guide plate, an optical sheet, and the like on a liquid crystal cell. As shown in Figs. 4(a), (b) and (c), an optical sheet 16 is provided below the liquid crystal cell 12, and a light guide plate 18 is provided below the optical sheet 16. The light 26 propagating through the light guide plate 8 is equally supplied to the liquid crystal cell 12 by the optical sheet 16. The optical sheet 16 includes a diffusion sheet 14 and a cymbal sheet 15. A light source (not shown) such as a fluorescent lamp, a light guide plate 18, and an optical sheet 16 are fixed to the frame 20 to constitute a backlight. A groove 30 for mounting the optical sheet 6 and positioning is provided on the frame 2''. An ear piece (projecting portion) 28' which protrudes a part of the optical sheet 16 is provided and the ear piece 28 is fitted in the groove 30. A frame 22 is provided on the peripheral portion of the frame 20 and the liquid crystal cell 12. The frame 22 is used to concentrate the components of the liquid crystal module 1 into one, or to mount the liquid crystal module on the product frame. In the case of the IPS liquid crystal module, when the bezel 22 is in close contact with the liquid crystal cell 12, and the bezel 22 presses the liquid crystal cell 12, the glass substrate of the liquid crystal cell 12 will be curved. The warpage of the glass substrate causes a change in the thickness of the liquid crystal layer. Therefore, the portion of the liquid crystal cell 12 that is in contact with the bezel 22 causes the white color to fade, thereby degrading the display quality. The liquid crystal cell 12 and the bezel 22 are required to have a gap d. In addition, the TN (twisted nematic) liquid crystal module does not lower the liquid crystal module 1 even if the frame 22 is closely connected to the liquid crystal cell 12.

This is because the liquid crystal alignment of the liquid crystal layer of the TN liquid crystal module is different from that of the ips liquid crystal module. Therefore, even if the thickness of the liquid crystal layer changes, the influence on the liquid crystal alignment is still small. As described above, in order to fix the optical sheet 16 to the frame 2, the groove 30 is cut out on the frame 20. Although the light 26 is led from the light guide plate 18 to the liquid crystal cell 12 by the optical sheet 16, a part of the light 26 leaks from the groove 3〇. Since the material of the frame 22 is stainless steel, pure aluminum, hard aluminum alloy, etc., the leaked light 26 is reflected on the frame 22 and appears in the display area of the night crystal unit 12 from the gap d between the liquid crystal cell 12 and the frame 22. , causing light bubble leakage to reduce display quality. As shown in Fig. 5, in the case where the wall 32 is provided on the groove 30 of the frame 20, the light % can be prevented from reaching the frame 22 by the wall 32. However, since the material of the frame 2 is made of a highly reflective material, the light 26 is reflected at the wall, and the light 26 is leaked from the gap d between the liquid crystal cell 12 and the bezel 22. A method of embedding the elastic member in the gap 4 can be considered. However, since the gap d is 〇. i to G. 2 mm, it is difficult to apply pressure to the liquid crystal cell 12 when the elastic member is buried in the gap d. SUMMARY OF THE INVENTION Light from a liquid crystal cell The object of the present invention is to provide an IPS liquid crystal module that prevents leakage between a backlight and a frame. (Means for Solving the Problem) It comprises: a liquid crystal unit having a protruding portion, the IPS liquid crystal module of the present invention is intended to be used, and an optical sheet is disposed under the liquid crystal unit

O:\89\89749.DOC 1303736 之光源（未圖示）、導光板丨8及光學片16安裝在框架20上即可 構成背光源。在光學片16上設置突出的耳片28，藉由將耳 片28嵌入於溝30内，即可將光學片16固定在框架20上。 光吸收體24a，可由黑色膠帶、黑色印刷、黑色塗飾或錢 鉻所構成。黑色膠帶等，係設計成不密接於液晶單元12。 鑛鉻之顏色係大致接近黑色的濃灰色，其可吸收光26。 當從導光板18藉由光學片16將光26導引至液晶單元12 時，光26就會從框架20之溝30洩漏出。洩漏出的光26，可 由邊框22之内壁的光吸收體24a所吸收，而不會從邊框22與 液晶單元12之間隙d洩漏出。因而，不會降低jpg液晶模組 10之顯示品質。 圖1中，雖在邊框22之内壁全體上設置光吸收體24a，但 是亦可只在從溝30洩漏出之光26照到的部分設置光吸收體 24a 〇 如圖2所示，就在框架2〇之溝3〇設置壁32，使光％不會在 邊框22洩漏出的情況加以說明。該情況，亦利用框架2〇之 i32而使光26反射，並在液晶單元12與邊框22之間使光26 洩漏出。藉由將與圖！相同的光吸收體24b設在壁32上，換 言之設在溝30之内壁上，以防止光26洩漏出。又，亦可以 光吸收體24b來構成壁32之部分。 圖1中雖在邊框22之内壁設置光吸收體24，但是如圖3所 示，亦可以覆蓋光學片16之耳片28之周緣的方式設置光吸 收體24c。藉由以光吸收體24c來覆蓋耳片28之周緣，以防 止光26從光學片1 6洩漏出。A light source (not shown), a light guide plate 8 and an optical sheet 16 of O:\89\89749.DOC 1303736 are mounted on the frame 20 to constitute a backlight. A protruding tab 28 is provided on the optical sheet 16, and the optical sheet 16 can be fixed to the frame 20 by embedding the tab 28 in the groove 30. The light absorbing body 24a may be composed of black tape, black printing, black finishing or chrome. The black tape or the like is designed not to be in close contact with the liquid crystal cell 12. The color of the ore chrome is approximately dark, dark gray, which absorbs light 26. When the light 26 is guided from the light guide plate 18 to the liquid crystal cell 12 by the optical sheet 16, the light 26 leaks from the groove 30 of the frame 20. The leaked light 26 can be absorbed by the light absorbing body 24a on the inner wall of the bezel 22 without leaking from the gap d between the bezel 22 and the liquid crystal cell 12. Therefore, the display quality of the jpg liquid crystal module 10 is not lowered. In Fig. 1, although the light absorbing body 24a is provided on the entire inner wall of the frame 22, the light absorbing body 24a may be provided only in the portion where the light 26 leaking from the groove 30 is irradiated, as shown in Fig. 2, in the frame. The wall 32 is provided in the trench 2, so that the light% is not leaked out of the frame 22. In this case, the light 26 is also reflected by the i32 of the frame 2, and the light 26 is leaked between the liquid crystal cell 12 and the bezel 22. By going with the map! The same light absorbing body 24b is provided on the wall 32, in other words, on the inner wall of the groove 30 to prevent the light 26 from leaking out. Further, the light absorbing body 24b may constitute a part of the wall 32. In Fig. 1, although the light absorbing body 24 is provided on the inner wall of the frame 22, as shown in Fig. 3, the light absorbing body 24c may be provided so as to cover the periphery of the ear piece 28 of the optical sheet 16. The peripheral edge of the tab 28 is covered by the light absorbing body 24c to prevent the light 26 from leaking out of the optical sheet 16.
