In such a direct type backlight module, the line light source is provided inside a frame body including a front frame on which a liquid crystal panel is mounted, and a bottomed rear frame that can be separated from the front frame and opened at one end side. In addition, at the front of the rear frame, as disclosed in, for example, Japanese Patent Laid-Open Publication No. 2000-2877877, a reflecting plate that reflects light from a line light source to the panel side is provided. The use of a chirped reflecting plate can improve the Utilization efficiency of light source light. [Summary of the Invention] However, in the above-mentioned conventional device, since the reflecting plate is installed in front of the rear water, and the reflecting plate is supported by the rear frame, a light emitting device with a stone in the rear frame is caused. . _It is the case that the LCD panel needs to respond to the need to increase the hair volume of the device. The second phase is the second phase: ☆ Xi Yue added the material cost of the rear frame, and also needs, towel: The structure of other components of the light-emitting device, such as a frame that can be graveed, has a structural tranquility, which leads to an increase in cost. Fu 1 In view of the above-mentioned question Cong Cong, the purpose of this issue is to provide — 5 200540518 types even when the light emitting area is increased!

In addition to the above description, the light-emitting surface constituent member 4 may include a polarizer and other functions or the same function. In addition, instead of the diffusion sheet 42 described above, the diffusion sheet 42 made of synthetic resin such as acrylic resin or polycarbonate resin or frosted glass may be used instead of the diffusion sheet 42. However, since the diffusion sheet 42 It is thicker and heavier than the diffusion sheet 42. Therefore, from the standpoint of weight reduction of the light-emitting device, the diffusion sheet 42 is preferably used. In addition, in the above description, the lens sheet 4m is double-sided tape 7 The case where one side of the spoon is fixed to the front frame 2 is described as an example, but the method for fixing the light-emitting surface constituent member 4 is not limited to this. For example, the above-mentioned liquid crystal panel is less than 15 pairs (the heat generated by the lamp L and the like is small). It is estimated in advance. When the amount of deformation of the light-emitting surface constituent member 4 is sufficiently small due to the use environment of the light-emitting device ^, all four sides of the constituent member 4 may be fixed to the front frame 2 and / or the frame body 3. In addition, In the case where both sides of the surface constituent member 4 are fixed, it is preferable that the two sides that are perpendicular to each other (such as the above-mentioned left short side and upper long side) are fixed. Further, as described above, one side of the lens sheet is fixed

However, ▲ In the case where the light-emitting surface is composed of a short side with a large amount of deformation and a small side, the ^ Βθ panel has a heavier side, that is, the sky edge of the panel EP (the upper side is ^ to fix only the reaction of gravity) The upper plate 5 has a structure; the upper portion 5 of one of the sections is provided with each lamp L. Moreover, in the "5" surface 5a, the pair 2 is continuously formed only in the longitudinal direction, and the reflecting plate 5 And two inclined inclined side surfaces 5b which are continuous with the inclined side surface 5b, the reflecting plate 5 is inclined with respect to the front and the surface. That is, the opposite two sides of the four sides of 5a expand upward, The front side is bent upward, and the upper part of the oblique side surface 5b forming the above-mentioned rising angle of 90 degrees is folded in a square direction. Next, each of the straight folded side surfaces 5c is bent. Use the double-sided tape 8 above to fix it to the side 5c of the frame _ 1 A. As shown in the same figure, after the county = the inner side 31d, hold it as the oblique side 5b; on the frame 3, the front% and the length The frame ㈣ is the same as that of the part 31 ', the front 5a and the frame 3', because the surface 5a of the plate is tilted. The fixed free state, therefore, in the state where the angle of the reflecting plate 5 can be changed by 3. 3% with respect to the front surface, the p-plane is shown in FIG. 3 'in the short side direction of the reflecting plate 5, the front 5a' again There is a bow, and the edge portion is inserted into the groove portion 32f of the frame body 3. The edge portion is connected to the inner surface of the groove portion 32f to prevent the reflection plate 5 from falling / raising or rising. That is, the reflection The front edge of the short-side direction of the plate 5 is abutted on the back and front of the side of the plate 5 by 14 200540518 and supports the inside of the front side and the inside of the rear side of the groove portion 32f. The direction fixed to the point on the long frame portion 3 丨 is combined to 'can prevent the front 3a from sinking or rising due to its own weight, and can prevent the reduction of the reflective function caused by this. In addition,' as a reflection; ^ shirt section It is preferable to provide a groove portion 32f that guides and supports the front surface and the rear surface of the front edge portion as described above, but it is also possible to prevent the reflection plate 5 from hanging down by only guiding the rear support portion. In addition, the reflection plate 5 It is better to choose a sheet with low light transmittance, The light of L will not leak out to the back of the light emitting device (the reverse side of the liquid crystal panel EP) through the reflecting plate 5. That is, the structure of the reflecting plate 5 makes the light leaking to the back as small as possible, thereby preventing the This leakage of light causes a decrease in the brightness of the planar light emitted from the light-emitting surface. In addition to the above description, a reflective plate having a high light transmittance can also be used. However, in this case, it is preferable to reflect the light. The inner side of the reflective surface of the plate is painted black or an aluminum oxide vapor deposition film is provided to absorb light leakage. The above-mentioned lamp L is, for example, a straight tubular linear light source composed of a cold cathode tube, as shown in the example of FIG. Each of the lamps 1 is installed inside the housing 3 with a predetermined interval dimension maintained by the lamp tube partition 12. In addition, "as shown in Fig. 3", in each of the lamps L, rubber supporting frames 11 are mounted on electrodes provided at both ends thereof. This electrode is connected to the inverter 10 fixed to the mounting plate 9 mounted on the rear surface 32b of the short frame portion M, and each lamp L is driven to be turned on by the inverter 10. Each lamp 1 is held at the lamp mounting hole (light source support portion) 32e fitted into the frame 3 by the rubber support frame =

Due to the advantages, each light source supporting portion on the frame body 3 is kept S = one dedicated lamp support can be eliminated, and the number of components of the light-emitting device can be reduced, and the cost can be reduced. In addition to the above description, the conversion unit 10 is mounted on the inner side of the reflecting plate 5 or on the outer side surface 32c next to the front frame 2. The above-mentioned lamp tube partition 12 has a base mounted on the front face 5a of the reflecting plate 5.卩 12a, and two substantially U-shaped holding portions 12b are arranged on the base portion 12a in the short-side direction described above. Hold in the holding portion 12b, the lamp L. Furthermore, the lamp tube partition 12 may be made of resin or rubber, and is preferably made of a material that has shape stability to light, heat, and ultraviolet rays and is not affected by the electric properties of the lamp. In addition, the tube partition 12 should be white or a colorless material with no abnormal light emission, which has the same reflectivity as the reflection, 5. In addition, the holding portion 12b should not hinder the light reflection of the lamp as much as possible, especially in the case of using a white material, as shown in Fig. 2, and its shape does not cover the light-emitting surface of the lamp L. In addition, the lamp tube partition n is integrally provided with a support pin ′ on its base 仏. The support pin 13 is supported on the light-emitting surface constituent member 4. In addition, the two official partition plates 12 and the support pin 13 are each provided, for example, in a square of 3 mm square, and are arranged in a zigzag pattern as shown in FIG. 2. In this way, by avoiding arranging the lamp tube partition 12 and the support pin 13 in a straight line as much as possible, it is possible to make the lamp 1 and the light emitting surface constituting member 4 piercingly supported, thereby greatly suppressing the above-mentioned lamp tube partition 12 and the support. The shadow of the underpin 13 appears on the light-emitting surface. In addition, since the base 2a of the lamp tube partition 2 is mounted on the front surface of the reflecting plate 5, the flatness of the front surface 5a can be more firmly maintained. In short, since the holding portion i2b of the lamp tube partition 12 supports the middle portion of the lamp 12, and both ends of the lamp L are supported by the lamp mounting holes 32e of the frame 3, the lamp 5 and the lamp tube partition are obtained in the front 5a. By supporting the plate 12 and the frame 3, the shape stability of the front face 5a can be improved by these lamps L and the like, and the flatness can be more reliably ensured. In addition to the above description, it is also possible to use a separate lamp partition and support pin.

在具有上述結構的本實施例中，由於反射板5安裝成擋住了框體3的後方開口部3b，用該框體3作為反射板5 的支承構件，因此與用具有前面的後框作為反射板的支承 f件的上述習知例不同，即使在發光面的發光面積增大的情況下，也可以大幅度地抑制框體3的重量的增加。另外，由^可以大幅度地抑制反射板5的支承構件（框體3)的重量的增加，因此對於安裝在該框體3上的前框2等豆他各構成構件，也沒有必要再改變其㈣或尺寸框二=加_化其結構。這樣的結果是可以容易“現與液晶顯示裝置的輕量化’同時抑制上述框體光=:牛的材料費用的上升，可以製成成本低廉的發九裝置1與液晶顯示裝置。框本實施例中，由於反射面5的前面5a是在與二：Γ二部31處於脫離的狀態’且在傾斜側面％幺=二變的狀態下安裝在框體3上，因此即 = 發出的熱或因吸水等而發生收縮(變」寸上迷角度可以因應該變形而變化。結果，反射板 17 200540518 5可以維持前面5,平坦狀‘態，米發，生的變形吸收掉，可以防止反射板5發生周該變形而造g的功能降低。、，另外在上述。兄明中，疋對適用於液晶顯示裝置的背光模組的t月況進行的說明，但是本發明的發光裝置只要是原的後方、將光源的光反射至發光面構成構 ^側的反射板，設置於上述發光面構成構件的後方、設有容許射到該發光面構成構件_側的光源光通過的前方開口部的框體’且反射板I在該框體上，擋住該框體 =口部的裝置就可以，而能夠適用於發出平面狀的照明光的知明為具以及其他裝置的光源。另外，也可以不用上述的由冷陰極管構成的直管狀線光源，而用υ形等非直管狀線光源或具有球形發光部分的點光源。而且，在士述說财，是龍用㈣—體結構的情況行《兒Θ i_疋本發明的框體不限於此，也可以採用例如 ^形四邊的各邊部分分別製成，再料些各邊部分結合起來構成的框體。此外’還可以使用例如具有在—個上述的 =邊部分財間部分開有缺π、大致呈c形的平面的框 f。但是，使用上述那樣的™體構成的框體，由於可以容易，提高剛性與（支承）強度，而且又不需要進行框體的所心好是使用1的框體，侧i'在用上述樹脂义成框體日年’因為可以用射出成型方便地製成框體，因此更是合適。另外’在上述說明中，對只在反射板的長邊方向設有 #斜側面與折_面’折回側面固定在框體上的結構進行In the present embodiment having the above-mentioned structure, since the reflecting plate 5 is installed to block the rear opening portion 3b of the frame body 3, and the frame body 3 is used as a supporting member of the reflecting plate 5, it is similar to using a rear frame having a front face as a reflection The above-mentioned conventional example of the supporting member f of the plate is different, and even when the light-emitting area of the light-emitting surface is increased, the increase in the weight of the frame 3 can be significantly suppressed. In addition, since the weight of the support member (frame body 3) of the reflection plate 5 can be greatly suppressed, it is not necessary to change the other structural components such as the front frame 2 mounted on the frame body 3. Its ㈣ or size box two = plus _ to change its structure. As a result, it is possible to easily "currently reduce the weight of the liquid crystal display device" while suppressing the increase of the above-mentioned frame light =: the increase in the material cost of the cow, and it is possible to produce the low-cost hair-receiving device 1 and the liquid crystal display device. In the front surface 5a of the reflecting surface 5 is in a state separated from the two: Γ two parts 31 'and is installed on the frame 3 in a state where the inclined side% 幺 = two changes, that is = the heat or Shrinkage occurs due to water absorption, etc. (The angle of change can be changed due to deformation. As a result, the reflection plate 17 200540518 5 can maintain the front 5, flat state, and the hair deformation can be absorbed to prevent the reflection plate 5 The function caused by this deformation is reduced. In addition, in the above. Xiongming, I will explain the state of the backlight module suitable for the liquid crystal display device, but the light emitting device of the present invention only needs to be the original one. Rear, a reflecting plate that reflects the light from the light source to the light-emitting surface-constituting structure, is provided behind the light-emitting-surface constituting member, and is provided with a front opening that allows the light source light that is incident on the light-emitting-surface constituting member to pass through. The frame of the mouth portion and the reflection plate I on the frame body may be a device that blocks the frame body = the mouth portion, and it can be applied to a light source that emits planar illumination light and other light sources. In addition, Instead of the straight tubular linear light source composed of the cold cathode tube described above, a non-straight tubular linear light source such as a υ-shape or a point light source with a spherical light-emitting portion can also be used. Moreover, in the literature of the scholar, it is a dragon-body structure. Case line "儿 Θ i_ 疋" The frame of the present invention is not limited to this, but can also be made by, for example, each side portion of the ^ -shaped four sides, and then the frame body formed by combining the side portions. In addition, 'can also be used For example, there is a frame f having a plane of approximately π and a substantially c-shape in one of the above-mentioned = edge portions and the inter-financial portion. However, the frame body made of the ™ body as described above can easily improve rigidity and support. ) Strength, and do not need to make the frame. The favorite is to use the frame of 1, the side i 'in the above-mentioned resin is used to define the frame year-by-year' because the frame can be easily made by injection molding, so it is even more Suitable. Also 'in In the above description, the structure in which the #sloping side and the folding surface are provided on the long side of the reflecting plate and the folding side is fixed to the frame is performed.
