Description

2005. ^ IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a light-emitting device, a backlight core set for a liquid crystal display device ', and a liquid crystal display device. [Prior Art] A liquid crystal display device has a backlight module for illuminating the liquid crystal panel at the back of the liquid crystal panel (refer to Japanese Patent Application Laid-Open No. 2002-258770 or Japanese Patent Laid-Open No. 2003-234012) The backlight module for a liquid crystal display device has a structure as shown in FIGS. 21 and 22, for example. The backlight module 100 shown in the figure has a structure in which a cold cathode lamp L is provided in a casing 101. The housing 101 is a metal lower frame 102 having a cross section of an elliptical shape, and a diffuser plate 103 and an optical film 104 are mounted on the optical film 104. Then, the optical film 104 is covered with a metal upper frame 105. structure. The lower frame 102 is formed into a shape as shown in FIG. 22 by sheet metal processing of a metal plate. That is, the lower frame 102 has a rectangular bottom surface 102a, a side suspension erected from opposite sides stealing from the rectangular bottom surface, and an outer side extending from a difficult upper side to support the diffusion plate 103. Upper surface i〇2c. The lamp tubes L are provided on the bottom surface 102a, and a plurality of lamp tubes L are provided side by side in parallel with the side legs along the length direction. Each of the lamp tubes [is a lamp support body on both sides of which the side 102b is not provided on the bottom surface = supports both ends in the longitudinal direction. In addition, the tube support body 106 is generally formed by molding a synthetic resin. 20053¾ ^ Using a light-emitting device such as a backlight module, the liquid crystal display has a size corresponding to the size of the screen. ^ Module = different 'then the lower frame 1102 that constitutes the housing 101 must be 105; and the size of the ks support body 106 must also be changed to the size of each backlight module. = Frame 105 and tube support 106. Gui is' because LCD TVs are products that require a variety of sizes, even products of the same structure will have different backlight modules with different sizes due to different sizes, and a variety of sizes of the lower frame wood 102 The upper frame 105 and the tube support body 106 are also required. The lower case 1G2, the upper frame 1G5, and the lamp tube support body 106 constitute the county. They are manufactured by the customs. If the size of the shirt is required, it is 1 ^ the number of molds corresponding to the number of size types This will increase the V-cost cost of the scarf. For example, in general, the metal: the frame 102 and the upper frame 105 are made by sheet metal stamping. In addition, in general, the lamp tube support 106 made of resin is made by injection molding. No matter which type is manufactured, the number of molds corresponding to the number of * size types is required. 〃 In recent years, with the increase in the size of LCD TVs, the manufacturing of casing components has also increased in size, and the cost of molds has been high. In addition, the rigidity of the case becomes insufficient when the components are enlarged. In particular, the torsional strength of the wood 1 is weakened, and it is easy to produce the twist as shown in FIG. 23, and the distortion of the lower frame 102 will distort the entire backlight module, thereby distorting the mounting surface of the liquid crystal panel. It is difficult to keep the LCD panel stable in 2005. In order to prevent such distortion, you can consider increasing the thickness of the lower frame 102, the thickness of the Deng piece, or using a material that is not prone to distortion. However, since t-like countermeasures increase the weight of the casing, the weight reduction required for the backlight unit cannot be achieved. In addition, in order to prevent distortion, if the material of the lower frame 102 is changed from light weight to SUS and other materials, it will not only cause weight increase, but also lose the ability to obtain the aluminum lower frame. Good dispersing performance, so it must be set separately on the chin 102 made of SUS; the heat will also increase the weight due to the heat sink. [Summary of the Invention] Therefore, the object of the present invention is to easily solve the problems caused by the diversification of the size of liquid crystal display modules and the like, and increase the cost, and to increase the rigidity even in the case of large-scale. The surface dead light device 'is characterized by including a light-emitting component facing the bottom plate, a plurality of divided frames and a hinge body arranged on the above-mentioned hair === bottom and installing the knitted stretched surface, and the pivot body is made of plant-pressed material or, In this structure, the surface components, the bottom frame, and the frame of the light-emitting device are formed. The oblique === pifTdoc 2050 in these parts can be formed with the same extruded material as the extruded material, and the connected points can be appropriately adjusted #m_length body = structure, because of the size of the light-emitting device frame. In addition, 〇 to W is not there, because the splitter body is squeezed to use only one mold (extrusion die and stand-up stretched material, so the splitter body can be length. So / ^ 、 · 桓子) Make a frame of any length. As a result, a variety of molds can be made with a small number of molds. 2 :: The frame of the shape of the light-emitting assembly,?: The frame structure with a large degree: The rigidity of the component or the base plate is insufficient. It can also protect the overall rigid structure of the cancer. ^ Pressing material J extension = Shen material, although resin can be used to squeeze the aluminum, aluminum alloy or magnesium alloy. The above-mentioned frame is preferably connected using a corner connection cutting frame. Although Qiu Ya · ㈣, the above points in the corner can be used with the screw Hi 4 D ^ body and "difficulty _ connection also ... ', dry connection, adhesive bonding, etc., but through the corner connection and it is used to connect Dividing the frame can improve the frame and use the corner connector. Therefore, Ding Cai took the “line light source” from above, and most of the above-mentioned line light sources are located inside the backlight module. The “backlight module” is divided into components to form the interior of the backlight module. On the side of the space, the # 1 surface and the side surface are formed with the above-mentioned linear light source channel portion on the side portion so as to be located on the internal space of the backlight module ... a part of λ, may be located inside the frame, In order to avoid 200535518 15809pif.doc, the linear light source and the light source channel portion are blocked, it is better to install a reflective sheet larger than the side portion on the side portion. When most linear light sources are located in the internal space of the backlight module, the low-luminance parts at the two ends in the length direction will cause the light emitting surface to deteriorate in light quality, so these parts must be hidden. In the case where the divided frame has a side surface portion constituting a side surface of the internal space of the backlight module, a light source channel portion is formed on the side surface 卩, and the light source channel portion located in the internal space of the backlight module is given through this light source channel portion. A part can be located inside the body, so that part can be hidden. At this time, even if the divided frame having the side portion through which the light source thermally passes passes has the same cross-sectional shape as the divided frame having the side portion through which the light source can pass, the divided frame having the side portion through which the light source cannot pass can pass through the reflection sheet. Blocking the light source channel, came to a question. On the other hand, a sub-frame with a side portion through which the light source can pass can also form a linear light source that avoids entering the frame from the interior space of the backlight module, and captures the reflection sheet of the light source channel to solve this problem. Problem, so the commonization of the divided frames can further reduce costs. The above-mentioned light-emitting surface component is composed of a plurality of planar optical components. The above-mentioned divided frame is preferably installed in a state where the periphery and the end portions of the plurality of planar optical components are covered. The optical component holding portions that respectively hold a plurality of planar light preforms are prevented from entering the space between the plurality of planar optical components. The planar optical components referred to here are diffuser plates,

An optical film (diffuse film, lens film, polarizing film, etc.) has an optical function that plays a certain role in the light emitted from a light source. X In the case where multiple planar optical components overlap to form a light emitting surface, such as 200503551fi fruit dust entering between optical components, dark spots will be generated to reduce the quality of the light emitting. Lets go into human optics;

Special feature: The backlight module for liquid crystal display devices needs to be very high. Therefore, it is necessary to prevent dust from entering the human body, and it is necessary to check whether the light quality is higher than a predetermined quality. , X

Although the dust adhering to the surface of the light-emitting surface constituent member can be removed afterwards, the dust that enters the optical component has to be disassembled before being removed. Therefore, assembly must be performed in a clean environment such as a dean room so that the powder does not enter between the optical components.

Based on such requirements, in the conventional surname structure shown in FIG. 21 to FIG. 23, the structure is easily diffused by the lower frame 102 and the upper frame 105, or the structure of the optical film 104. Therefore, the assembly process of holding the diffuser plate 103 or the optical film 104 with the lower frame 102 and the upper frame must be performed in a high-clean environment such as a clean room. In addition, when the lower frame 102 is connected to the upper frame 105, the lamp support 106 must be attached to the lower frame 102 to support the light source L on the lamp support 106. The final stage of the assembly process of the backlight module. Therefore, the inspection of the light emitting quality is performed only in a state where the backlight module is assembled, so the efficiency is very low. In contrast, the frame is provided with an optical member holding portion that holds the plurality of planar optical members in a state where the peripheral end portions of the plurality of planar optical members are completely covered. The body is equipped with multiple planar optical components, and it is difficult for dust to enter between multiple planar optical components. 12 oc

The light emitting surface constitutes a rectangular shape of the light emitting surface on the light emitting surface; the light emitting surface constitutes a rectangular frame of the component, and the light source supporting the inner space of the frame with the four sides of the component.

The structure is connected at right angles. ‘1 ===== the inside face of the space, and at the same time, _ =: ΐ 二 = the internal space of the body is stretched, and the length of the divided frame is connected to the i portion. ’The shaft has an angle formed by cutting off the side of the upper leg

By dividing each of the C bodies with the inner face facing the inner space of the frame, the body is formed. By constructing a rectangular frame that supports the light-emitting surface of the light-emitting surface that can use the light emitted from the light source, these inner surfaces can form side-reflecting surfaces. There is no need to provide additional components that form side-reflecting surfaces. The structure is simplified. When a divided frame having an inner surface portion that extends into the inner space of the frame body and is disposed obliquely is connected to each other at a corner portion of the frame body to form a right angle, the inner surface portion inclined inwardly will be at the corner portion. The connecting portions conflict with each other, but in the present invention, the corner connecting portions formed by cutting out the inner surface portion are formed at the end portions in the longitudinal direction of the divided frame body, so the divided frames may not be mutually connected at the corner portions. Conflictingly connected. It is preferable to form a notch through which the linear light source passes through the post-processing of extrusion molding or 13 20053mc stretch molding on the inner surface portion of the divided frame. After the processing, a gap through which the linear light source passes is formed, and a split frame that can be passed by the same mold source and a cut frame that cannot be passed by the linear light source can be used. Therefore, the cost can be reduced by the commonization of the molds. It is best that all the divided frame bodies are formed by the same die so as to reduce the cost through the common use of the die. This hair_f light module for liquid crystal display transposition uses the above-mentioned luminous moonlight n, which touches the liquid crystal panel mounting surface of the above-mentioned split body, and is addicted to μ, + m. The light emitted from the light-emitting surface shines at night, day, day, day, day, day, and night. In addition, the present LCD device is a liquid crystal display device having a backlight module on a liquid crystal panel and a night crystal panel, and the above-mentioned light emitting device is particularly used as a backlight module. With the present invention, as the constituent parts of the light-emitting device, that is, the divided frames formed by stretching materials are connected, because:: = :! molds can also form divided frames of various lengths and can be low Cost-effective manufacture of various sizes of frames. In order to make the above and other objects of the present invention easy to understand, the lower female animal and a stove are shown as follows: The details of the embodiment of the present invention will be described with reference to the drawings.

Fig. 1 to Fig. 9 show the first group 1A) 1. The light-emitting device shown in the figure is a light device (the back of the diffuser plate 3 of the backlight mold surface is provided with light < ”,, /, are the so-called direct-type backs (Fig. 2), 1 has a surface structure A located at the peripheral end of the light-emitting surface component A on the front side of the light source L, and is located at the back (Fig. 1). (Bottom), the bottom plate C, A, A, and β located at the light source L form the shape of the light-emitting device i ^ two fine A, B, and C constitute the overlapping structure of the film light. 卩 read 3 optical films 4 The diffusion plate 3 is made of resin or glass, and the light emitted can be diffused, so that the second light source L on the light emitting surface can pass through the optical film 4 such as a diffusion film or a lens film, and the optical characteristics can be adjusted. The light from the light-emitting surface is irradiated, so that the liquid crystal panel 2 emits light. The back of the θ panel 2 and the light-emitting layer 2 are formed, and a polarizing film, a specific limitation. @ TmgCUmin) film can be used. The number j: =: The frame B is formed into a 7-rectangular frame shape, which can support the moment to form the end of the four edges of the tear. This frame B consists of two 15 20053 electric The long-side divided frame is composed of 6A, 6B and two short-side divided frames 7A, 7b, which are connected to the divided frame 6A, 6B, 7A, and 7B. In this embodiment, as shown in FIG. The shape of the cross-section is ^. The dagger cuts the frame because it is made by Lü, so its weight is lighter, so the weight is lighter.

A divided frame having such a cross-sectional shape can be produced by applying pressure to a heated billet and extruding from a mold (die) having an outlet shape and a cross-sectional shape as shown in FIG. 3. . In this embodiment, the long-side divided frames 6 and 8] and the short-side divided frame 7B are formed by the same mold. ~ In addition, the divided frame produced by extrusion processing can be subjected to post-processing processes such as cutting processing to form screw holes or notches. In this way, since extrusion processing is used, the eight-cut frames 6A and 6B for the long sides and the divided frames 7a and 7B for the short sides can be formed in the same mold to realize the commonization of the molds.

In addition, since extrusion processing is used, it is possible to produce divided frames with a long production rate. Therefore, according to the f-inch of the light-emitting device (backlight module), divided frames of various lengths can be formed with a common mold. In particular, | the direct type backlight module has the same thickness regardless of its size, so the structure of the frame itself does not need to be changed. As long as the length of the sub-frame = is adjusted, it can meet the needs of various sizes. Mold costs can also become very low. In this way, even when it ’s used in LCD TVs and other day sizes (vertical white 16

Ji: In the case of a variety of commercial light-emitting devices, it is possible to easily solve the problem by adding a lot of cost. The back cut frames 6 and 8 and 7 and 8 are inclined on the side. Outer 2: The portion 12 projects from the back side into the backlight module and protrudes from the back portion 11. The portion on the back portion 11 side is larger than the back portion 11 ′, and is used as a positioning protrusion of the bottom plate C. The light-emitting surface component A, the bottom plate C, and the space enclosed by the light-emitting surface constitute the interior of the backlight module and the surface is within the internal space s. The first source of j ύ and L. is located on the front side of the divided pivots 6Α, 6Β, which is formed with 15 suitable for inserting the light-emitting surface 'two face 12': In fact, as shown in Figs. 1 and 3 = the front end 12a To the backlight module: the: the light-emitting surface of the inner surface Π is formed on the left side of the drawing) extending the support surface [5a / piece A heart support surface ...]. In addition, the first part of the frontal part of the eclipse forms an X point facing 15a and 15b opposite to each other :: ^: 部 15 5 'two supporting faces and two supporting faces ..., 5b Located at ^ = 2. In addition,, the surface moving deep. Component part on light emitting surface

In addition, since the diffuser plate 3 or the optical film 4 must be supported in the plane direction, the holding portion IS must be a supporting structure that can easily solve the problem of shrinkage, that is, shrinkage. The expansion of the optical fiber A is shown in Figure 4. The rectangular frame B is shown in Figure 4.

The ends of the divided frames 6A, 6B, 7A, and 7B are like 4 pieces of the f connector 17 ... and 连接 are connected as shown in FIG. 5

▲ The corner connector 17 is a die casti product made of metal such as an inscription. The corner connector 17 has corners constituting a rectangular frame body b, that is, a connector body 17a having a square (rectangular) front surface, and a first insert piece 17b and a second insert provided on the connector body 17a 'and protruding. Tablet 17c. The two insertion pieces 17b and 17c extend in a direction which is 90 degrees apart. By inserting these insertion pieces 17b and 17c into the inside of the divided frames 6A and 7A, the two divided frames can be connected at right angles. Since the insertion pieces 17b and Uc of the connector 17 are connected to each other so as to fit into the inside of the divided frame body, the divided frame body can be easily and accurately connected. In addition, the insertion pieces 17b and 17c have the same width as the interval between the front portion 10 and the back portion η, and can be inserted against the inside of the outer surface portion 13 while being sandwiched by the front portion 10 and the back portion U. The insertion pieces 17b and 17c are formed with screw holes 18 for inserting screws for joining the divided frame body and the insertion piece. In addition, at both ends in the longitudinal direction of the divided frames 6A, 18 2005358518c 6B, 7A, and 7B, screw holes 19 are also formed at positions corresponding to the screw holes 18 when the insertion pieces 17b and 17c are inserted. The screw holes 19 are formed by post-processing performed after extrusion processing. As described above, by inserting the four divided frame bodies 6A, 6B, 7A, and 7B into the respective insert pieces 17b and nc of the four corner connectors 17, the 1J frame bodies 6A, 6B, 7A, and 7B is fixed to the insertion opening 乜 and i7c 'to form the frame B shown in FIG. 2. By connecting the divided frames 6A, 6B, 7A, and 7B, a solid rectangular frame is formed to obtain a structure that is not easily twisted. Furthermore, the corners of the frame body B are connected by the corner connector 17, so that the distortion of the frame body B can be better prevented, and a structure that is light in weight according to this embodiment and that is not easily distorted even if it is manufactured by injection molding S can be obtained. In addition, the light-emitting device i of this embodiment has a mounting surface B of the liquid crystal panel 2 which is less likely to be distorted in the structure. Therefore, the mounting surface 1G of the liquid crystal panel 2 is not easily distorted and can stably support the liquid crystal panel 2. The inner face 12 of the divided frame is extended toward the inside of the backlight module: Ji ^ If you directly increase the extrusion by 1 to connect the separated body = right angle, the lengthwise end of the inner face 12 will be separated from the other. The lengthwise ends of the inner surface portion 12 of the frame = are in conflict, so f cannot be connected. Therefore, as shown in FIG. 5, the frame bodies 6A, 6B, 7A, and 7B are divided into end portions in the longitudinal direction of the face 12. Cut obliquely to form a corner connecting edge portion i2c at both ends of the inner = long square Λ. Figure 6 shows the wearing view of the part of the divided frame that is not cut. In order to avoid conflicts between the other divided frames of the soldier, the medial part of the inner face and the part of the back 19 20053 are cut away (the dotted line in Figure 6). The cutting of the end portion c is performed in the post-processing after the extrusion processing. sμ, the divided frame bodies 6A and 7A connected at right angles are connected to each other by the σ ^ edge portion 12 formed by being cut to form the shape shown in FIG. 7. 6B 1 to 1 'have the function of holding the cold cathode lamp (linear light source) L. The short-side divided frames 7A and 7B are the same as the long-side divided frames 6A and 1 =. The cold-cathode lamp tube L described above is a straight tube having f ^ poles at both ends in the length direction, and is mounted on a lamp holder (rubber holder) 22, and the electrodes are covered. 23 extends from the electrode of the lamp tube through the lamp tube support 22, and the wiring part 23 Jr. 2: is attached to the connection benefit 24. The connector 24 and the lighting device of the light source are connected to each other by the inverter 32. The cutting frames 7A and 7B are designed to hold the above-mentioned rubber brackets so as to enjoy ^ L. Therefore, in the short-side divided frames 7A and 7B, that is, the carrier, a recessed portion 2 with a rubber bracket 22 is formed. The clothing portion 26 is shown in FIG. 1 Shown are the cut-outs that cut out the inner face 12 into the notch in accordance with the shape of the rubber bracket 22, Fig. 7 and Fig. ". In addition, 'the enemy enters the notch portion 26 (missing = ,, and is performed in the post-processing of the press processing.) / Cheng is inserted into the notch portion 26 of the rubber bracket 22 is also a light source (both ends in the longitudinal direction), located at Umbrella, &, part of the light source channel portion used in the frame B. By passing the rubber bracket 22 into the embedded notch portion through the development L, the two ends in the length direction are divided by a pair of frame 7A, 7 light source L According to Figure 8). In this way, the middle part of the light source L in the length direction = hold (see .77, most of its 20 20053mi points will be located in the internal space S of the backlight module, and a part of the light source B (both ends in the length direction) is located in the frame Inside B. The light source L may be supported by the long-side divided frames 6A and 6B. In addition, when the light source L is a non-straight linear light source such as a U-shape, the light source channel portion 26 may also be used. Inside the curved frame B of the light source L. On the surface of the inner surface portion 12 formed by the above method, a side reflection surface 28 reflecting light from the light source L is formed. The side reflection surface 28 may be a white or metal surface to form a diffuse reflection surface. Or a total reflection surface (specular reflection surface). Specifically, a white reflection sheet (reflection tape) 28 may be affixed to the surface of the inner surface portion 12, or a white coating method may be applied to the inner surface portion 12. In the case of this embodiment, the reflecting sheet 28 has a shape similar to that of _face 12 _. That is, the short-side divided frames 71 and 7B are formed on the short sides of the notch 26 for insertion of the rubber holder 22. Case, anti The radiating sheet 28 needs to be formed with a cutout corresponding to the shape of the cut-out part 26 for human insertion, and it is not necessary to form the reflective sheet 28 without the long-side divided frames 6A and 6B for the cut-out part 26 for insertion. In addition, when the surface of the inner surface portion 12 can be used as the reflective surface, the processing of obtaining the reflective surface 28 is not necessary. Fig. 8 is a band showing that the frame body B and the light-emitting surface component A are assembled into one body. Schematic diagram of the assembly of the frame with the luminous surface. First 'connect the 4 divided frames 6-8, 3, 7-8, and 7 at 21 o'clock 2005200518 Cut the frame 6-8, 7-8, and ^ to form a concave-edge opening In this state, install = as shown in the figure, the diffuser 3 and the optical film 4) from the divided frame 7A, \ R surface constituting part A (the open end of the extension is inserted, thin The light-emitting surface constitutes the edge end of the ㈣-shaped holding portion ls, and is inserted into the perimeter of the insertion direction of the divided frame 6A. Then, the corner connectors 17 and 17 will be multiplied by 15. Connect them to complete the frame B. , So-come; the split frame 6B of Y and the piece A are held in the frame B without making the light emitting surface constitute With the function of holding the light-emitting surface component A. In other words, the frame B has the four sides of the light-emitting surface component A and, because the divided frames are connected to each other as long as they are in the state of being fixed; The portion IS holds the light-emitting surface and constitutes the component A. Therefore, without the frame B, it is possible to form the portion #A that is mounted on the frame B. The smooth structure is also provided by the groove-shaped holding portion (optical component protection / multiple surface shapes).

In addition, in the table, the state that the light emitting surface and the component A are installed after the light source L has been mounted on the frame is shown, but the light source [can also be formed on the light emitting surface. Install after file A. In addition, after the light-emitting surface component A is mounted on the frame B, the quality inspection can be performed between 22,200,53 m of the expanded optical film 4 (a plurality of scales are provided for this inspection). When the inspection light source ^ is used to install the light source L for the backlight module, can the light emitting surface constitute part A due to dust or light,

^ Φ When the light-emitting surface component A is inserted into the holding portion 15, it can also be framed by 1 ^ 3 divided frames, and it can be performed with only 2 divided Lfi. #Of course, you can also do at the same time. The connection of the frame and the insertion of the light-emitting surface component A into the holding portion 15 are 0 π return eggs 1 and FIG. 2. The bottom frame c is mounted on the frame B, which is equipped with the light source 1 source after assembly as shown in FIG. 8. On the surface of the bottom plate c, there is only a single sheet, and the radiating sheet 3G 'constitutes a bottom surface reflection of the light emitted by the reflected light source 1.

The bottom surface c and the diffuse reflection sheet 30 constitute a bottom surface reflection surface component. The bottom surface can be made by coating the surface of the bottom plate C with white. The base plate C is formed of a metal material such as aluminum with high heat dissipation. Although the base plate C is easily twisted, the frame B has sufficient rigidity. Therefore, even if the base plate C is easily twisted, it is mounted on the frame b. You can stop distortion. In addition, the base plate C may be made of a low-rigidity material such as a synthetic resin plate or a thin plate. In this embodiment, 23 200535518 15809pif.doc, which has good heat dissipation properties, such as aluminum, can be used. There is also no need to have a heat sink. Τ, set to 1 large size, because the rigidity of the frame b is increased by 7 pins:, j, " a σ, the thickness of the base plate c to increase the rigidity ', and two liquid crystals with a size of 50 pairs can be used.

A stack of inverters 32 The circuit can also be installed in the frame wL as shown in the bottom reflecting surface components, that is, the bottom plate c and the expansion are formed with the wiring portion 2 3 of the light source L from the bottom reflection port and the notch 34 that passes through to the inside. The assembly 23 completes the assembly of the light-emitting device 1 (backlight module) by using the screws 36 in the state Γ on the base plate C and the diffuse reflection sheet 30 (see FIG. 9). In addition, there are ^ holes 7 'formed on the rw wind hole 37 ~ 舰, and on the frame B. The holes corresponding to the screw holes 37 are also formed at the positions corresponding to the screw holes 37. c After being combined with screws and the like, the rigidity of the entire casing is obtained from Qiu's backlight module 1 (the LCD panel 2 is mounted on the front panel mounting surface of the frame B) 1G ±. The rigidity of the liquid crystal panel m is ensured by the frame B, and the distortion of the liquid crystal panel Anmai surface 10 is small, so the liquid crystal panel 2 can be installed very stably. 24 2005 ¾¾ In addition, the backlight module adopting this embodiment can prevent distortion even if the bottom plate c is thinner than | 乂, so it can be good = as the bottom plate C 'while suppressing the increase in weight and making the structure Early. Special feature] That is, in the backlight module of this embodiment, the frame B has the supporting function of the liquid crystal panel, the supporting function of the light-emitting surface component A, the supporting function of the base plate c, and the light-emitting surface. There are many functions, such as the function of maintaining the interval between 5 pieces A and the bottom plate c, and the number of pieces is reduced. The structure of the other components (the bottom plate C, etc.) is also simplified. 10 to 13 show a light emitting device (a liquid crystal display =: a backlight module) 1 according to the second embodiment. The light-emitting device according to the second embodiment is different from the light-emitting device according to the second and second methods mainly in the cross-sectional shape of the divided frame, and the installation positions of the light source L and the light source L are different. It should be noted that the following descriptions of the provinces are the same as those of the first embodiment. The division frame of the second embodiment is the same as the first embodiment. The storage body has an = side division frame and a long side division frame. Here are two types of division frames. All the shapes are the same. That is to say, the divided frames ΑΑ, 7Α,

It is a poor inner eve side portion 12, and its length in the direction of the bottom plate c during the extrusion process is Hi-straight to the bottom plate C (the bottom plate reflection surface 30). In the engineering, the short-side divided frame 7A, 7B of the first embodiment is cut out, and the portion 12 is formed as a rubber bracket for the light source channel portion, and the long-side divided frame of the first embodiment is formed. 25 200535511 of 6A, 6B, the notch portion 26 is not formed on the inner surface portion 12. The presence or absence of these cutout portions 26 is a difference between the shapes of the two divided frames 6A, 6B, 7A, and 7B. In the divided frames 6A, 6B ′ 7A, and 7B of the second embodiment, the inner side portions 12 of the short-side divided frames 7A and 7B and the long-side divided frames 6A and 6B extend only to the rubber of the light source L ( Stand 22) high position. In the embodiment shown in FIG. 10, the length of the inner surface portion 12 of the short-side divided frames 7A and 7B in the direction of the bottom plate C is only to the extent that it is in contact with the rubber bracket 22, and the inner sides of the long-side divided frames 6A and 6B are inside. The face 12 has the same length (see FIG. 13). By shortening the inner surface portion 12 of the short-side divided frames 7A and 7B, a gap is not formed between the inner surface portion 12 and the bottom plate C (the bottom plate reflection surface 30), and a light source passage portion for ensuring the passage of the light source L can be formed. 50 (see Figure 12). The light source channel portion 50 allows the light source L to pass through, and there is a gap between the light sources L. On the surface of the inner surface portion 12, a side reflection sheet 28 for reflecting light is adhered with a double-sided tape or the like. This side reflection sheet 28 not only covers the surface of the inner side surface portion 12, but also has a shape that avoids the light source L and blocks the light source passage portion 50. That is, the width L2 of the side reflection sheet 28 is larger than the width L1 of the inner surface part 12, so that it can cover not only the inner surface part 12 but also the light source channel portion 50. Specifically, the side reflection sheet 28 extends almost to the bottom plate C (base plate reflecting surface 30). That is, the side reflection sheet 28 has almost the same width as the inner surface portion 12 of the first embodiment (see Figs. 12 and 13). 26 200 ^ 3 ^ ^ 4i ^ 〇c There are also 'notches 52' formed at the two ends of the light source L of the side reflection sheet 28 of the inner surface portion 12 of the divided frames 7A, 7B to avoid the light source L ( (See Figure 11 and Figure 12). The width L3 of the reflection sheet 28 in which the notch 52 is present is preferably equal to or greater than the width L1 of the inner surface portion 12. That is, it is better to satisfy L1 $ L3 < L2. On the other hand, there is no need to form the above-mentioned notch 52 on the inner surface portion 12 of the divided housings 6A, 6B where the two ends of the light source L in the longitudinal direction are not located (see Fig. 13). In this way, it is not necessary to form a notch 26 for passing (or fixing) the light source L in the inner surface portion 12 of the short-side divided frames 7A, 7B of the second embodiment in the post-processing after the extrusion processing. . Due to the short length, the divided frame bodies 7A, 7B and the long-side divided frame bodies 6A, 6B can solve the problems caused by the existence of the light source L by using the shape change of the reflective sheet 28 which is easy to process, so the manufacturing cost can be reduced. In the light-emitting device of the second embodiment, the light source L is mounted on the base plate C. That is, as shown in FIG. 10 and FIG. U, on the bottom plate [, end portions of both ends in the longitudinal direction of the light source L are provided with side walls as the light source holding wall 54 and rubber brackets 22 at both ends of the light source L. The rubber bracket 22 formed on the light source holding wall 54 is inserted into the groove *, so that both ends of the light source L in the longitudinal direction are held on the bottom plate c. In addition, a side wall constituting the light source holding wall 54 is formed with a screw hole 5 and a bottom plate c, which are secured by screws (not shown). On the outer surface 13 of the divided frame 6A, 6B, 7A, 7B, a screw hole 13a is also formed at a position corresponding to the upper screw hole 54b, and the outer portion 27 of the frame ^ 20053m side portion u and the bottom plate c are formed. The sidewall 54 is fixed. In addition, the side wall 54 of the bottom plate c can be placed not only on the short side of the bottom plate where the two ends in the length direction of 総 L are located, but also on the long side of the bottom plate, and the side wall 54 and the long side can be fixed with screws or the like.
