[Prior Art] With the expansion of the information society, display devices capable of displaying information have been widely developed. These display devices include liquid display (LCD) devices, organic electroluminescent display devices, plasma display devices, and electroluminescent display devices. In the above display device, the advantages of the LCD device are high luminance, small body φ, and low voltage driving and full color configuration. Therefore, the LCD device can be widely used for mobile phones, navigation systems, portable computers, televisions, and the like. The LCD device requires a backlight unit that emits light when it is illuminated, otherwise does not emit light. Therefore, the LCD device controls the amount of light emitted by the backlight unit to display an image. Fig. 1 is a cross-sectional view showing a related art edge type backlight unit. As shown in FIG. 1, the edge type backlight unit 10 includes: a fluorescent lamp 12 placed on the side of the light guide plate 11, a reflection sheet 14 placed under the light guide plate 11, and an optical sheet placed on the light guide plate 11. 15. The light emitted from the fluorescent lamp 12 enters the light guide plate 11. However, part of the light emitted by the fluorescent lamp 12 does not enter the light guide plate 11 to cause light leakage. To prevent light leakage, a lamp cover 13 with a reflective function is provided to surround the fluorescent lamp 12. Thus, part of the light emitted by the fluorescent lamp 12 directly enters the light guide plate 12, and the remaining light is reflected by the lamp cover 13 into the light guide plate 11. Light entering the light guide plate 11 is directly directed to or reflected by the optical sheet 14. The optical sheet 15 allows light to scatter the liquid crystal panel (not shown) that is irradiated onto the optical sheet 15. On the other hand, another different type of backlight unit 20 includes: a retroreflective sheeting 24 placed on the bottom cover 23, a plurality of fluorescent lamps 22 disposed on the retroreflective sheeting 24, and an optical sheet laminated on the fluorescent lamp 22. 25, as shown in Figure 2. The unexplained number "2" indicates another optical sheet different from the optical sheet 25. The edge type backlight unit described above includes a fluorescent lamp placed on one side of the light guide plate, with the following problems: adjacent to the fluorescent lamp A brightness deviation occurs between the areas far from the fluorescent lamp. This situation gradually deteriorates as the size of the liquid crystal panel increases. 201009457 In the side type backlight unit 7C, the shape of the fluorescent lamp appears (or is displayed) on the liquid crystal panel. In order to emphasize this, the distance between the fluorescent lamp and the optical sheet can be increased. In this case, the backlight unit is thicker, making it difficult to be as thin as the LCD device. [Invention] Therefore, the present embodiment relates to an LCD device. It completely avoids one or more problems caused by the limitations and disadvantages of the prior art. The object of the present invention is to provide a light source plate with a plurality of light guide plates and a light source module for directing light toward the light guide plate to realize thin Dimensions and uniform brightness, as well as a single LCD device with this backlight. β ... this implementation _ traditional features and excellent service in the town description towel _, thus the description will gradually become clear 'or can be practiced by this The object of the present invention and other advantages can be achieved or obtained by the invention and its requirements, the structure specifically referred to in the drawings.

The one-sided portion is not intended to limit the claims. Other aspects and advantages are discussed in connection with the examples. The above general description and the following detailed description of the invention are intended to be illustrative of the invention. [Embodiment] A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described hereinafter are provided by way of example only for transmission to those skilled in the art. Thus, these embodiments may have different forms and are not limited to the described embodiments. Again, the size and thickness of the device can be exaggerated to magnify the reason for the convenience of the figure. Wherever possible, the same reference numerals in the drawings refer to the Fig. 3 is a perspective perspective view of the LCD device of the first embodiment of the present invention. Fig. 4 is a cross-sectional view showing the LCD device of Fig. 3. Fig. 5 is a plan view showing the LCD device of Fig. 3. Fig. 6 is a perspective view of a light source module in the LCD device including Fig. 3. Referring to Figures 3 and 4, the LCD device of the first embodiment of the present invention includes a backlight unit 1 and a liquid crystal panel 200. The backlight unit 100 emits light supplied to the liquid crystal panel 2 . The liquid crystal panel 200 adjusts the transmittance of light from the backlight unit 1 to display an image. 201009457 The LC^ device further includes a driving unit (not shown) for driving the liquid crystal panel 200 to control its light transmittance. The drive unit includes a timing controller, a pole driver, and a data driver. - Whenever the controller receives video data, it controls signals from systems including video cards. Video data package t red (8), green (6) and blue (8) data. The control signal includes a data enable signal EN, a data clock DcJk, a vertical sync signal Hsync, and a horizontal sync signal Hsync. Similarly, the timing controller captures the gate control signals used to drive the gate drivers and the data control signals used to drive the data drivers. Further, the timer reassigns the video material to the appropriate format ' for display on the liquid crystal panel 2'. The gate driver is responsive to the gate control signal from the timing controller and generates a scan signal for scanning the various gate lines on the liquid crystal panel 200. The data driver converts the video data of the timing controller into an analog video voltage in response to the data control signal from the timing controller. The liquid crystal panel 200 is divided into a plurality of pixel regions arranged in a matrix for displaying red materials, green data, and blue data. Finally, the liquid crystal display panel 2 includes a lower substrate 21, an upper substrate 220, and a liquid crystal layer (not shown) which is inserted between the upper and lower substrates 21 and 220 and which is divided into a plurality of liquid crystal cells. The lower substrate 210 may include a plurality of mutually intersecting gate lines and data lines, a plurality of thin film transistors disposed in the insertion regions of the plurality of gates and data lines, and a plurality of pixel electrodes connected to the respective thin film φ transistors. The intersection of the plurality of gates and the data lines defines the lower substrate 210 as a pixel area of a plurality of pixels. Thus, each of the plurality of pixels may include a thin film transistor and a pixel electrode. The upper substrate 220 includes a color filter layer including a plurality of red choppers, green filters, and blue filters corresponding to respective pixel regions. The upper substrate further includes a black matrix disposed between the color multiplexers and a common electrode disposed on the color furnace aperture and the black matrix. The upper substrate 220 can be applied to a liquid crystal panel 2 of a TN (Twisted Nematic) mode. Alternatively, if the liquid crystal panel 20 is in the IPS (Plane Switching) mode, the common electrode of the color filter layer and the upper substrate 220 is formed on the lower substrate 210. In the liquid crystal panel 200, the thin film transistor connected to each of the gate lines can be turned on by the scan signal of the gate driver. Then, the analog data voltage applied to the data line by the data driver is supplied to each pixel electrode via the 201009457 active film. At the same time, a common voltage of direct or optional current is applied to the common electrode. Thus, the liquid crystal molecules of the liquid crystal layer are rearranged based on the analog voltage on the pixel electrode and the common voltage_potential difference on the common electrode. Thereby, the amount of transmission by the backlight unit 100 can be adjusted to display an image. The backlight unit 100 includes a bottom cover 110, a plurality of light source modules 14A, and an optical sheet 15A. The bottom cover ΐ ω accommodates and supports a plurality of light source modules 140, an optical sheet 15A, and a liquid crystal panel 2''. although
圖未示，與底盍Π0匹配並保護液晶面板2⑻的頂箱可進一步包括於LCD 裝置中。 底蓋110包括-平面的第—區域、—由第—區域邊賴斜向上地延伸的 第二區域。在第-區域中，排職數個光賴组14()。第三區域可形成底蓋 ® 110的側壁’允許光學片150和液晶面板200設置在上表面上。在此，液晶 面板200可妓於接觸或分離於光學片⑼。因此，複數個設置於底蓋ιι〇 的第-區域上的光學片15G可與設置於底蓋UG的第二區域相分離。由此， 由光源模組140發射的光線可均勻地照射向光學片15〇。或者，如果由光源 模組14G所射出的級是均勻的，底蓋11()的第二區域可瓣至將光源模 組140與光學片150接觸。 底蓋no的第一區域分割成複數個發光區域a、b、c、d，如第5圖 所不’複數個光源模組14〇可設置於其上。此時，複數個光源模組14〇可 排列為矩陣形。事實上，光源模組140分別地設置在底蓋11〇的發光區域a 瘳至D上。換句話說，光源模組M〇的加矩陣設置於底蓋11〇的第一區域 上。為解釋方便’雖然第一實施例的LCD裝置採用光源模組140的加矩 陣’但不侷限於此。 光源模組140每個包括一導光板13〇和一 LED(發光二極管）陣列12〇, 如第6圖所示。LED陣列12〇設置為導光板13〇的側表面並發射光。更 特別地LED陣列120可分別地設置接近於定義於底蓋11〇的發光區域a 至D的邊界區域，如第5圖所示。例如設置於發光區域a的光源模組 ^ LED P車列可接近於發光區域A至D間邊界區域設置於發光區域b的 光源模組140的另- LED陣列可接近於發光區域B至〇間邊界區域。 LED陣列120包括一沿導光板13〇平行的長度方向延伸的基板似和 複數個安錄基板122的LED 125。基板122上的咖125 互分離地 201009457 設置。基板122可為一包括金屬線設置於其上的印刷電路板（PCB)或一金 屬核心PCB。 LED125可包括紅、綠和藍LED ’或者僅包括複數個白LED。同樣， LED125可為僅向其前方發射模式或向側邊發射模式。雖然沒有詳細地顯示 於圖中，如果前發射模式的LED125用於第一實施例的LCD裝置中，可設 置其前面附有反射材料的反射元件以圍繞LED125，用以將LED125發射的 光導入設置於LED125側方向的導光板130中。相反地，側發射模式的 LED125可應用於第一實施例的LCD裝置，每個LED125可設計為每個 LED125的側面敞開用以輸出光線’而每個LED125的剩餘側面為鏡面塗覆 而沒有輸出光線。由此，由LED陣列120發射的光線可進入導光板13〇， φ 可通過導光板130而亮度均勻地供應於光學片150。 光學片150可包括散射片（圖未示）、稜鏡片（圖未示）和一保護片（圖 未示）。散射片和棱鏡片能夠使導光板130照射的光散射，並會聚到液晶面 板200。保護片用於保護散射片和/或稜鏡片。沒解釋的元件符號“16〇”指的 是反光片，用於反射來自導光板130的光線。 在此方式中，本發明第一實施例的LCD裝置排列複數個光源模組14〇， 每個光源模組140包括導光板130,並因此允許均勻亮度的光線由導光板 130供應於光學片150。我終，均勻免度的光線可照射向液晶面板2〇〇的整 個表面。相反地，現有技術的LCD裝置應用與光源相鄰的導光板的第一區 域和遠離光源的導光板的第二區域的光線亮度不同，因為它僅包括與液晶 ^ 面板相對的單個導光板。特別地，當液晶面板尺寸增加時，第一實施例的 LCD裝置與現有技術的LCD相比，可提供更多亮度均勻的光線。 同樣地’由於現有技術的直接型LCD裝置包括複數個等間隔設置的光 源’低亮度的光線在每個光源的前區域發射，高亮度的光線在光源間區域 發射。由此’必然增加複數個光學片與複數個光源之間的距離。因此，現 有技術的整個直接型LCD裝置厚度增加。 相反地’依照本發明第一實施例的LCD裝置包括複數個應用均勻亮度 的導光板130’以便縮小導光板130和光學片150間的距離。因此，第一實 施例的LCD裝置的整個厚度大大地減小。換句話說，LCD裝置可以更薄。 雖然本發明第一實施例的LCD裝置具有前述優點，其產生的線具有比 8 201009457 導光板130所產生的光線更亮，在LED陣列12〇的長度方向上（也就是， 在導光板130的長度方向上），由於LED陣列12〇設置於發光區域A、B、 C、D之間，如第7圖所示。這是由於導光板13()不存在於LED陣列12〇 中。換句話說，為產生均勻亮度的光線，導光板13〇可覆蓋所有各個發光 區域A、B、C、D。然而，導光板13〇沒設置在各個LED陣列，其設置鄰 近於發光區域A、B、C、D的邊界區域。最後，不同亮度的光線產生於導 光板130和LED陣列所設置的區域中。 同樣，既然LED陣列120必須與導光板130分離地設置’由LED陣列 120發射的部分光線不進入導光板13〇，而是通過LED陣列和導光板 130間隙射向前方。射向前方的光線亮度可高於通過導光板13〇的光線亮度。 ©、進-步地，在本發明第—實施例的LCD裝置中，對應於明亮顯示的區 域的熱點由包括於LED陣列120的複數個LED 125引起的。在此，輿夂個 ㈣125直_爾料絲13G人卿㈣㈣域姆^亮U 因為入射部的部分區域與LED 125相近。同時，與LED 125間相對的每個 導光板130人射部的剩餘部分不亮（或比較暗），這是因為入射部的剩餘部 分與LED 125相距較遠。因此，沿著LED陣列12〇的長度方向在接近各 個LED P車列120的每個導光板13〇的入射部產生熱點的波形流(丽㈣㈣ stream) ° 為此，提出適合防止亮線和熱點的其它LCD裝置。其它實施例的lcd _裝置包括-些與第-實施例具有相同功能和結構的元件。相同的元件標記 與第一實施例相同的數字，將在說明書中簡要地陳述並省略。 "" 第8圖為本發明第二實施例的LCD裝置的分解透視圖。第9圖為第8 圖的LCD裝置的剖視圖。以及，第10圖為包括於第8圖的Lcd裝置中 導光板的透視圖。 參考第8和9圖，本發明第二實施例的LCD裝置包括一背光單元 和-液晶面板400。背光單το 300包括-底蓋310、複數個光源模組·、 和光學片350。液晶面板400和光學片350在說明書中省略，是因為其可 過第一實施例的LCD裝置理解。 光源模組340可設置於定義在底蓋310的複數個發光區域a至l。發 光區域A至L可包括四個定義於第一方向（即，X軸方向上）的區域和三 201009457 光板330 ，同樣地’十二個導光板330可設置於各個絲模組34〇中。事實上， 導光板330排列為四個在X軸方向、三個在γ轴方向。最後，十二個導光 板330總數可設置。 LED陣列320設置於平行於導光板33〇的每個導光板33〇賴表面。 每個LED陣列320可相對於各個光源模組34〇或由複數個χ轴方向的光源 模組所共享’樣，LED陣列320可位於鄰近於發光區域α至l的邊界區 域0 ❹Not shown, the top box that matches the bottom 盍Π0 and protects the liquid crystal panel 2 (8) may be further included in the LCD device. The bottom cover 110 includes a --plane first region, and a second region that extends obliquely upward from the first region edge. In the first-region, a number of posts are ranked 14 (). The third region may form a side wall of the bottom cover ® 110 to allow the optical sheet 150 and the liquid crystal panel 200 to be disposed on the upper surface. Here, the liquid crystal panel 200 can be in contact with or separated from the optical sheet (9). Therefore, a plurality of optical sheets 15G disposed on the first region of the bottom cover ι can be separated from the second region disposed on the bottom cover UG. Thereby, the light emitted by the light source module 140 can be uniformly irradiated to the optical sheet 15A. Alternatively, if the stage emitted by the light source module 14G is uniform, the second region of the bottom cover 11() can be splayed to contact the light source module 140 with the optical sheet 150. The first area of the bottom cover no is divided into a plurality of light-emitting areas a, b, c, and d, as shown in Fig. 5, a plurality of light source modules 14A may be disposed thereon. At this time, the plurality of light source modules 14A can be arranged in a matrix shape. In fact, the light source modules 140 are respectively disposed on the light-emitting areas a to D of the bottom cover 11A. In other words, the adding matrix of the light source module M is disposed on the first region of the bottom cover 11A. For convenience of explanation, the LCD device of the first embodiment employs a matrix of the light source module 140, but is not limited thereto. The light source modules 140 each include a light guide plate 13A and an LED (Light Emitting Diode) array 12A, as shown in FIG. The LED array 12A is disposed as a side surface of the light guide plate 13A and emits light. More specifically, the LED array 120 can be respectively disposed close to the boundary area defined by the light-emitting areas a to D of the bottom cover 11A as shown in Fig. 5. For example, the light source module disposed in the light-emitting area a, the LED P train can be close to the boundary area of the light-emitting areas A to D, and the other-LED array disposed in the light-emitting area b of the light-emitting area b can be close to the light-emitting area B to the daytime Border area. The LED array 120 includes a substrate 125 extending in the longitudinal direction of the light guide plate 13A and a plurality of LEDs 125 of the plurality of recording substrates 122. The coffee makers 125 on the substrate 122 are separated from each other 201009457. The substrate 122 can be a printed circuit board (PCB) or a metal core PCB including a metal line disposed thereon. LED 125 can include red, green, and blue LEDs or only a plurality of white LEDs. Likewise, the LED 125 can be in either a forward mode or a side emitting mode. Although not shown in detail in the figure, if the front emission mode LED 125 is used in the LCD device of the first embodiment, a reflective element with a reflective material attached thereto may be disposed to surround the LED 125 for introducing the light emitted by the LED 125 into the setting. In the light guide plate 130 in the LED 125 side direction. Conversely, the side emission mode LEDs 125 can be applied to the LCD device of the first embodiment, and each of the LEDs 125 can be designed such that the side of each of the LEDs 125 is open for outputting light' while the remaining side of each of the LEDs 125 is mirror coated without output. Light. Thereby, the light emitted by the LED array 120 can enter the light guide plate 13A, and φ can be uniformly supplied to the optical sheet 150 through the light guide plate 130. The optical sheet 150 may include a diffusion sheet (not shown), a cymbal sheet (not shown), and a protective sheet (not shown). The diffusion sheet and the prism sheet can scatter the light irradiated by the light guide plate 130 and converge to the liquid crystal panel 200. The protective sheet is used to protect the diffusing sheet and/or the cymbal sheet. The unexplained component symbol "16" refers to a retroreflective sheeting for reflecting light from the light guide plate 130. In this manner, the LCD device of the first embodiment of the present invention arranges a plurality of light source modules 14A, each of which includes a light guide plate 130, and thus allows light of uniform brightness to be supplied to the optical sheet 150 by the light guide plate 130. . At the end, I can evenly illuminate the entire surface of the liquid crystal panel 2〇〇. In contrast, the prior art LCD device uses a difference in light intensity between the first region of the light guide plate adjacent to the light source and the second region of the light guide plate remote from the light source because it includes only a single light guide plate opposite to the liquid crystal panel. In particular, when the size of the liquid crystal panel is increased, the LCD device of the first embodiment can provide more uniform brightness of light than the prior art LCD. Similarly, since the prior art direct type LCD device includes a plurality of equally spaced light sources, low-intensity light is emitted in the front region of each light source, and high-brightness light is emitted in the inter-light source region. Thus, the distance between the plurality of optical sheets and the plurality of light sources is inevitably increased. Therefore, the thickness of the entire direct type LCD device of the prior art is increased. In contrast, the LCD device according to the first embodiment of the present invention includes a plurality of light guide plates 130' to which uniform brightness is applied in order to reduce the distance between the light guide plate 130 and the optical sheets 150. Therefore, the entire thickness of the LCD device of the first embodiment is greatly reduced. In other words, the LCD device can be thinner. Although the LCD device of the first embodiment of the present invention has the aforementioned advantages, the resulting line has a brighter light than the light generated by the light guide plate 130 of 8 201009457, in the length direction of the LED array 12 (ie, at the light guide plate 130) In the longitudinal direction, since the LED array 12 is disposed between the light-emitting areas A, B, C, and D, as shown in FIG. This is because the light guide plate 13() is not present in the LED array 12A. In other words, in order to generate light of uniform brightness, the light guide plate 13 can cover all of the respective light-emitting areas A, B, C, D. However, the light guide plate 13 is not disposed in each of the LED arrays, and is disposed adjacent to the boundary regions of the light-emitting regions A, B, C, and D. Finally, light of different brightness is produced in the area where the light guide plate 130 and the LED array are disposed. Also, since the LED array 120 must be disposed separately from the light guide plate 130, part of the light emitted by the LED array 120 does not enter the light guide plate 13, but is directed forward through the gap between the LED array and the light guide plate 130. The brightness of the light that is directed toward the front can be higher than the brightness of the light that passes through the light guide plate 13 . In the LCD device of the first embodiment of the present invention, the hot spot corresponding to the brightly displayed area is caused by a plurality of LEDs 125 included in the LED array 120. Here, one (four) 125 straight _ er filament 13G person Qing (four) (four) domain m ^ bright U because the partial portion of the incident portion is similar to the LED 125. At the same time, the remaining portion of the human emitter portion of each of the light guide plates 130 opposed to the LEDs 125 is not bright (or relatively dark) because the remaining portion of the incident portion is far from the LEDs 125. Therefore, a waveform stream of a hot spot is generated in the incident portion of each of the light guide plates 13A adjacent to each of the LED P trains 120 along the length direction of the LED array 12A. (For this, it is proposed to prevent the bright lines and the hot spots. Other LCD devices. The lcd_device of other embodiments includes elements having the same functions and structures as the first embodiment. Identical component numbers The same numerals as in the first embodiment will be briefly stated and omitted in the specification.

And, Fig. 10 is a perspective view of the light guide plate included in the Lcd device of Fig. 8. Referring to Figures 8 and 9, an LCD device according to a second embodiment of the present invention includes a backlight unit and a liquid crystal panel 400. The backlight unit το 300 includes a bottom cover 310, a plurality of light source modules, and an optical sheet 350. The liquid crystal panel 400 and the optical sheet 350 are omitted in the specification because they can be understood by the LCD device of the first embodiment. The light source module 340 can be disposed in a plurality of light emitting regions a to 1 defined in the bottom cover 310. The light-emitting areas A to L may include four areas defined in the first direction (i.e., in the X-axis direction) and three 201009457 light plates 330, and similarly, twelve light guide plates 330 may be disposed in the respective wire modules 34A. In fact, the light guide plates 330 are arranged in four in the X-axis direction and three in the γ-axis direction. Finally, the total number of twelve light guide plates 330 can be set. The LED array 320 is disposed on a surface of each of the light guide plates 33 parallel to the light guide plate 33A. Each LED array 320 can be shared with respect to each of the light source modules 34A or by a plurality of light source modules in the x-axis direction. The LED array 320 can be located adjacent to the boundary area of the light-emitting areas α to l.

An incident portion corresponding to the hot spot in the LCD device of the first embodiment is generated. The overlap 11 between the light guide plates 33, the human target portion can be varied in the width of the w-width design, preferably in the range of 3 to 13 mm. The LCD device of the first embodiment of the present invention may further include a reflective iridium 337 disposed on a rear surface of the light guide plate 330 for reflecting light incident from the LED array 32. Each of the reflective films 337 may form a single body in the X direction with respect to the rear surface of the light guide plate. Also, the reflective film may be disposed in relation to the light guide plate 330 disposed in the Y direction. The reflective film 337 may be disposed on each of the light guide plates 330 except for the remaining area of the incident portion (i.e., the pitch from the start line of the incident portion to the edge of the light guide plate 140 with respect to the incident portion). In other words, each of the reflective films 337 is provided to cover the overlapping area between the light guide plates 330. Referring to FIG. 9, the first light source module 340a' including the first LED array 320a and the first light guide plate 330a is disposed on the first light emitting area A of the bottom cover 310.

so the panel can be prevented: ϋ9 now and the lion's human part produces a hot spot as described above. Further, (4) η to the second LED array 32, the light emitted from the 32 〇C is irradiated to the fiber through the respective light guide plates 330a, so that the brightness of each of the light guide plates is hooked. Therefore, light of uniform brightness can be irradiated onto the liquid crystal panel 4A. The front surface of each of the optical sheets to be applied in the second real LCD device may have an inclined shape as shown in Fig. 10. Also, each of the light guide plates 331a to 331 (in particular, 330a or 330b) may have a chamfered portion 361 which may overlap with the light guide plate 働 or 330c adjacent to the incident portion thereof. The chamfered portion 361 (e.g., 'the first light guide plate') may include a side surface perpendicular to the bottom cover 310 and a surface having the same slope as the rear surface of the adjacent light guide plate 33b. Thereby, the rear surface ' of the light guide plate 330b or 330c can be placed in contact with the rear surface of the adjacent light guide plate 33a or 33b. More specifically, the reflective film 337 disposed on the rear surface of the light guide plates 330a to 330c (particularly, 33〇b or 33〇c) may be in contact with the bottom surface of the chamfered portion 361 adjacent to the light guide plate 330a or 330b. Referring to Figures 8 and 9, the bottom cover 310 may include an element 313 which supports a plurality of light guide plates 330a to 330c due to the inclined rear surfaces of the light guide plates 33a to 330c. The support member 313 may be formed of a single body or separated from the bottom cover 310. The support member 313 can also be formed to designate two patterned light guide plates 330a to 330c. Further, the front surface of each of the support members 313 may be formed to have the same slope and shape as the rear surface of each of the light guide plates 330a to 330c. Thereby, the front surfaces of the light guide plates 330a to 330c can maintain a uniform level because the light guide plate 33 is applied to 33 ;; supported by the support member 313. The LED arrays 320a to 320c and the light guide plates 330a to 330c may be fixed to (or fixed to) 11 201009457 iim, and each threaded first through hole 333 may be formed in each of the light guide plate arrays: corresponding to the first pass The hole 333 and the second through hole 327 may be formed in each of the respective surfaces to form m, specifically, the substrate of the LED array. Similarly, a third hole (not shown) is provided on the second through hole 327 of the plate 310a to the milk cap 310. Finally, the screw 336 can pass through each of the first through holes 333 on the light guide 丨W 1 and the third hole in each of the T first covers 310 on the stencil, so that the light guide plate is 33 〇. C. The LED arrays 320a to 320c may be fixed to the bottom cover 31A. : « r = plate, 3% to yujin - the fourth pass formed at the edge portion opposite to the human portion is formed on the light guide plate to 33 〇c (in particular, the second and third light guide plates 働 ^ The fourth through hole of the edge portion may be disposed corresponding to the first through hole 333 formed adjacent to the light guide plate and the woven and inserted. Accordingly, the two light guide plates adjacent to each other (for example, 33 and 働 > The first through hole 333 can be formed by the screw 336 passing through a light guide plate through the (four) west through hole and the first through hole 333 of the other light guide plate spot. Therefore, the number of the screws 336 can be reduced. To accommodate the head of the screw 336 so that the head of the screw 336 does not protrude from the first through hole 33> Thus, although the adjacent light guide plate lions and the dirt overlap with the incident portion of the light guide plate application island, the overlapping light guide plates 330b and 330c The bottom surface of the chamfered portion 361 which closely contacts the other light guide plate 33A and the spot can be completed by the head of the screw 336. Fig. 11 is a cross-sectional view showing the LCD device of the third embodiment of the present invention. A perspective view of a light guide plate of the LCD device included in Fig. 11. In addition to the difference in structure of the light guide plate, the third solid The LCD device of the second embodiment and the structural steel of the LCD. Therefore, the LCD device of the third example mainly explains the light guide plate. In the LCD device according to the third embodiment of the present invention, the light guide plates 331ai331c each have a rear surface. It has the same flatness as the inner surface of the bottom cover 310, as shown in the nth and Η. In other words, the rear surfaces of the light guide plates 331a to 331c are not inclined. Similarly, the light guide plates 331a to 331c are each A first chamfered portion 362 formed at the incident portion, and a second chamfered portion 364 at each of the edge portions of the light guide plate opposite to the incident portion are formed. The first chamfered portion 362 can be formed by cutting The upper and left side edge portions 'the second chamfered portion 364' are formed by going to each of the light guide plates 33u to 3Mc by cutting off the lower and right side edge portions of each of the light guide plates 331a to 331c. At each of the second chamfer portions 364 The upper and side surfaces may be provided with a retroreflective element 347. The formation of the reflective element 12 .201009457 347 may be by adhering the reflective film or by applying the reflective material directly to the second of each of the light guide plates 331a to 331c with respect to the incident portion. The upper and side surfaces of the corners. The reflective material 347 may have two surfaces capable of reflecting light. Thereby, the light entering each of the light guide plates 331 & 331 can be advanced, and can be forwardly reflected by the respective reflective elements 347 (ie, perpendicular to the respective light guide plates) Similarly, the direction of the upper surface of 331a to 331c is output. Similarly, light entering each of the light guide plates 331 & 331c (for example, 331a or 331b) may advance toward the adjacent light guide plates 331b or 331c through the respective light guide plates 33ia or 331b. The second chamfered portion 364 of the light guide plates 331b and 331c is output to the front by the reflection of the light reflecting member 347 of the adjacent light guiding plate 331b or 331c, and overlaps with the respective first chamfered portions 362 of the adjacent light guiding plates 331a and 331. Although the width of the overlapping area of the light guide plates 331a and 331b becomes various types according to the specification of ®, it is preferably 3 to 13 mm. Independent of the reflective element 347, the retroreflective sheeting 360 is disposed on the bottom cover 31A. The reflector 36 〇 can reflect light, and each of the light guides 331 & 331 from the rear direction (continues to advance forward. The first LED P train 320a can be disposed between the first and third light guides 331 & 331b The second LED array 320b can be disposed between the second and third light guide plates 331b and 331c. In other words, the first LED array 320a can be disposed on the second light guide plate 331b because the second light guide plate 33 is disposed. The second corner portion 364 is configured to be detached from the first chamfered portion of the first light guide plate 331a. Similarly, the second LED array 320b may be disposed on the third light guide plate 331cir because the third light guide plate 331c is disposed. The second chamfered portion 364 is configured to overlap with the first chamfered portion of the second light guide plate. The light emitted by the Φ-LED array 32Ga is disposed on the third light guide plate 33. The light reflecting element 34 on the second chamfered portion 364 is reflected so as not to continue forward through the edge regions of the first and second light guiding plates 331a and 331b. Therefore, the above bright line is not generated. Also by the first LED device 331a The emitted light is reflected by the retroreflective element 347 disposed on the second light guide plate. Before the forward output, the region opposite to the gamma incident region of the first light guide plate is advanced. Therefore, more continuations can continue to advance, and the light efficiency can be improved. Further, when the first light guide plate is formed in the incident region of the first light guide plate The chamfered area 362 overlaps with the upper surface of the second chamfered portion of the second light guide plate (10) on which the reflection τ member 347 is disposed, and the light ray 'outputted by the upper surface of the first incident portion' is second by the second light guide plate 331b The reflective film on the upper surface of the chamfer 364 is shielded from continuing forward. Therefore, hot spots are prevented from being generated at the incident portions of the first 13 201009457 light guide plates 331a and 331b. On the other hand, the light emitted from the first LED device 331a is prevented from being emitted. The light loss caused by the incident portion of the first light guide plate 331a not continuing forward is solved by outputting the light emitted from the second LED array to the front through the incident portion and the overlapping portion of the second light guide plate 331b. Further, the light entering the incident portion of the first light guide plate 331a continues forward by the reflection of the light reflecting element 347 on the second chamfered portion 364 of the second light guide plate 331b before the output thereof is directed forward. A large amount of light can continue to advance, and light efficiency can be improved.

In other words, the LCD device of the fourth embodiment includes a plurality of light guide plates 530a to 530 which are not overlapped with each other as shown in Fig. 14. The light source module 540 can be disposed in a plurality of light emitting regions a to L defined on the bottom cover 51A. The light-emitting areas A to L may include four areas defined in the first direction (i.e., in the z-axis direction) and three areas defined in the second direction (i.e., in the Y-axis direction). In other words, 12 illuminating regions can be defined in the bottom cover 510. Each light source module 540 can include an LED array 520 and a light guide 10 plate 530. Similarly, twelve light guide plates 530 can be included in each of the light source modules 54A. In fact, the light guide plate 530 is arranged to include four in the X-axis direction and three in the γ-axis direction. Finally, a total of twelve light guide plates 330 can be provided. The LED P train 520 is disposed on the side surface of each of the light guide plates 53A of the parallel light guide plates 53A. Each of the LED arrays 520 can be disposed to be shared with respect to each of the light source modules 54A or by a plurality of light source modules 540 in the x-axis direction. As shown in FIG. 14 , the first light source module 54A may include a first LED array 52 and a first light guide plate 530a. The first light source module 540b may include a second LED array 520b and a second The light guide plate 530b, the third light source module 540c may include a third LED array 52〇c and a third light guide plate 530c. The first LED array 520a may be disposed on the 201009457 boundary region of the first and fifth light emitting regions VIII and £. The second LED array 520b may be disposed on the boundary regions of the fifth and ninth light emitting regions E and I. The first to third light guide plates 530a to 530c have accommodations for accommodating the respective LED arrays 520a to 520c, and a chamfered portion 564 as shown in FIG. The chamfered portion 564 is formed by a projection 566 which extends from the top edge of the incident surface of each of the light guide plates 520a to 520c on the side (for example, the γ-axis direction). The protrusions 566 may cover the respective LED arrays 520a to 520c. Extending in the Y-axis direction, the protrusion 566 of the first light guide plate 530a may be disposed near or in contact with the side surface of the second light guide plate 530b with respect to the incident surface of the second light guide plate 530b, as shown in FIG. Similarly, the protrusion 566 of the first light guide plate 530a may extend a length sufficiently long to cover the first LED array 520a. 〇 extending in the Y-axis direction, the protrusion 566 of the second light guide plate 530b may be disposed near or in contact with the third light guide plate 53C side surface of the incident surface of the third light guide plate 530c. Likewise, the protrusion 566 of the second light guide plate 530b can extend a length "long enough" to cover the second LED array 52A. A light reflecting member 547 may be disposed on the rear surface of the protrusion 566 of each of the light guiding plates 530a to 530c. The light reflecting element 547 shields the light emitted by each of the LED arrays 520a to 520c from entering the front area of each of the light guide plates 530a to 530c in the forward direction. A light reflecting member 547 is formed on the rear surface of the protrusion 566 of each of the light guiding plates 530a to 530c by attaching or directly coating the reflecting film. Preferably, the reflective material 547 can have two surfaces that are capable of reflecting light. Thus, the light generated by the first LED array 520a can be reflected by the light reflecting element 547 into the incident surface of the first light guiding plate 520a, and guided in the forward direction by the first light guiding plate 520a. Similarly, the light generated by the second and third LED arrays 520b and 520c is reflected by the respective light reflecting elements 547, and is guided by the first and second light guiding plates 530b and 530e in the forward direction. Therefore, more light can continue to move forward, improving light efficiency. Similarly, the light emitted by the first LED array 520a is reflected by the light reflecting element 547 of the first light guiding plate 53A, continuing to the side by not passing through the boundary regions of the first and fifth light emitting regions. Therefore, it is possible to prevent the above-described bright lines from being generated in the boundary regions of the first and fifth light-emitting regions A and E. Similarly, the above-described bright line can be prevented from being generated in the other boundary region of the fifth and ninth light-emitting regions E and I. Further, the light generated by the first LED array 520a continues to be reflected toward the protrusion 566 via the internal reflection of the first light guide plate 〇a, and is reflected in the forward direction by the other 15 201009457 of the light reflecting element 547 of the first light guide plate 530a. The light of the boundary regions of the first and fifth light-emitting regions VIII and £ has the same brightness as the boundary region light of the fifth and ninth light-emitting regions E and I. In the same manner, the light rays of the other boundary regions of the fifth and ninth light-emitting regions E and I have the same brightness as the light of the boundary regions of all of the fifth and ninth light-emitting regions E and I. Therefore, light of uniform brightness can be irradiated onto the liquid crystal panel 600. The symbol symbols "533" and "527" are indicated in the drawing, and although not explained, mean the through holes on the light guide plates 53a to 530e and the second holes on the LED arrays 520a to 520c. Similarly, a third hole (not shown) is formed on the bottom cover 510. Further, a fourth through hole (not shown) may be formed on the light guide plate as explained in the description of the LCD device of the second embodiment. Therefore, the light guide plates 53A to 53A and the LED arrays 520a to 520c are fixed to the bottom cover 51A by the through holes by being inserted into the third holes. As described above, in the LCD device of the embodiment of the present invention, the light guide plates are arranged to overlap each other to cover the LED arrays that are interposed therebetween, thereby blocking light and preventing light from passing through the portion of the light guide plate disposed on the LED array. Continue from the LED device to the front. Therefore, the LCD device prevents the generation of bright lines. Also, the LCD device forces light into the incident surface of the light guide plate without outputting toward the front side of the incident portion to prevent the generation of hot spots. The step-by-step LCD device allows light of the same brightness to be superimposed and outputted from all of the light guide plates so that the 'LCD device can emit light of uniform brightness on the liquid crystal panel. Various modifications and alterations of the present invention will be apparent to those skilled in the art. The various improvements and modifications (4) that are made to the present invention are within the scope of the present invention.
