光型方式兩種方式。其中之直下型方式係將多數個光源於基板 上矩陣配置’於自光源設置有某程度空間之位置上配置二散 板,而使亮度均勻化之方式,另一個之邊緣發光型方式則係沿 導光板之一側端(側面或底部)於一直線上空出適當間隔而配 置夕數個光源,使光線自導光板侧面入射,使亮度均勻化後, 使光自導光板之前面向液晶面板射出之方式。 若對採用邊緣發光型方式之液晶顯示裝置進行詳細說明,例 如’如圖1及圖2所示’通常構成為:於框架構件3之突出面 3a之前面側配置液晶面板2,將框架構件3之突出面%夾住, 於液晶面板2之背面側,依序配置光學片4、導光板6及反射 板7’沿導光板6之端緣部空出適當間隔而配置多數個光源5, 以自液晶面板2之前面緣部將該等之側面部覆蓋之方式配置 上底板1,於反射板7之背面側配置下底板8。 100137479 4 201232103 採用如上所述之邊緣發光型方式之液晶顯示裝置中,自光源 5射出之光之一部分藉由導光板6向前面側折射,經由光學片 4供給至液晶面板2,自光源5射出之光之其他部分藉由導光 板6向背面側折射,並藉由反射板7反射,經由導光板6及光 學片4供給至液晶面板2。然而,由於自光源5射出之光中, 存在較多不朝向導光板6而向框架(框)構件3射出之光,故有 "玄。P刀指失之可月b性。因此,先前揭示有:藉由賦予框架(框) 構件3之背面光反射性’而使自光源5向框架(框)構件3射出 之光反射並供給至液晶面板2(參照專利文獻1〜3)。 [先前技術文獻] [專利文獻] 專利文獻1 :日本專利特開2005-327720號公報 專利文獻2 :曰本專利特開2007-108739號公報 專利文獻3:日本專利特開2008-091317號公報 【發明内容】 (發明所欲解決之問題) 然而,已知例如如專利文獻1〜3般賦予框架構件3高反射 率性,則由於晝面中之光源附近會過剩地變得高亮度,產生亮 度之不均勻化,故反而變得較難視認。 因此’本發明嘗試揭示—種可將較多之來自光源之光供給至 液晶面板’且可抑制亮度之不均勻化的新框架構件。 (解決問題之手段) 100137479 5 201232103 本發明者自各種角度對如先前技術般賦予框架構件高反射 率性之情況下(參照例如專利文獻1〜3),晝面中之光源附近過 剩地變得高亮度而產生亮度之不均勻化之原因進行研究。其結 果為’例如,如圖7所示之「反射率99%框架」,於顯示晝面 中’對正交於配置光源之晝面端緣部之長度方向的中央垂直線 上之壳度進行測定後可知:若中央垂直線之光源附近出現之亮 度之峰值鬲於中央垂直線之中央部附近之峰值’則光源附近之 壳度變得過高而產生晝面整體上之亮度之不均勻化。因此,本 發明者將該發現進而發展,完成以下之本發明。 即,本發明揭示有—種框架構件,其係組入邊緣發光型方式 之液晶顯示裝置之構件,具備側壁部之—部分向内部突出之部 刀且,於背面之一部分或整面上,具備波長4〇〇〜8〇〇nm之 平均反射率為10%以上之光反射面,將該框架構件組入液晶顯 不裝置時’於顯不晝面中’自正交於配置光源之晝面端緣部之 長度方向的巾央垂直線上之光源側端部,至僅遠離該中央垂直 線整體長度之5%之長度之位置為止,所測定之最大點亮度係

例如,框架構件之背面之5〇%之面積部分為波長4〇〇〜8〇〇nm 之平均反射率為100%之光反射面,其餘之5〇%之面積部分於 波長400〜800 nm之平均反射率為〇%之情況等情況下,亦可 認為滿足上述本發明之框架構件之條件。 (發明效果) 右,、且入本發明之框架構件而構成液晶顯示裝置,則將光自光 ,朝向框架構件反射’由於可將來自光源之光較多地供給至液

Description of the Invention: [Technical Field] The present invention relates to an optical sheet for use in an edge-emitting type liquid crystal display device for use in order to improve party membership and uniform brightness. And a frame member used for fixing a light guide plate or a chassis. [Prior Art] Generally, the liquid crystal display device is configured such that a backlight unit that supplies light to the liquid crystal panel is disposed on the back side of the liquid crystal panel. In the backlight unit of the liquid crystal display 7F device, there are mainly two methods of a direct type and an edge type. Among them, the direct type method is to arrange a plurality of light sources on a substrate in a matrix to arrange two scattering plates at a position where a certain space is provided from the light source, and to uniformize the brightness, and another edge-emitting type is along the edge. One side of the light guide plate (side or bottom) is disposed at a proper interval on the straight line, and a plurality of light sources are arranged to make the light enter the side of the light guide plate to make the brightness uniform, and then the light is emitted from the front surface of the light guide plate toward the liquid crystal panel. . When the liquid crystal display device of the edge light-emitting type is described in detail, for example, as shown in FIG. 1 and FIG. 2, the liquid crystal panel 2 is disposed on the front side of the protruding surface 3a of the frame member 3, and the frame member 3 is disposed. The protruding surface % is sandwiched, and a plurality of light sources 5 are disposed on the back side of the liquid crystal panel 2, and the optical sheets 4, the light guide plates 6, and the reflection plate 7' are disposed at appropriate intervals along the edge of the light guide plate 6 to The bottom plate 1 is disposed so as to cover the side surface portions of the front surface portion of the liquid crystal panel 2, and the lower substrate 8 is disposed on the back side of the reflection plate 7. 100137479 4 201232103 In the liquid crystal display device of the edge light-emitting type as described above, a part of the light emitted from the light source 5 is partially refracted toward the front side by the light guide plate 6, and is supplied to the liquid crystal panel 2 via the optical sheet 4, and is emitted from the light source 5. The other portion of the light is refracted toward the back side by the light guide plate 6, and is reflected by the reflecting plate 7, and supplied to the liquid crystal panel 2 via the light guide plate 6 and the optical sheet 4. However, since light emitted from the light source 5 has a large amount of light that is emitted toward the frame member 3 without being directed toward the light guide plate 6, there is a "Xuan. P knife refers to the loss of the moon b. Therefore, it has been disclosed that the light emitted from the light source 5 to the frame (frame) member 3 is reflected and supplied to the liquid crystal panel 2 by imparting light reflection on the back surface of the frame (frame) member 3 (see Patent Documents 1 to 3). ). [Prior Art Document] [Patent Document] Patent Document 1: Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. (Problems to be Solved by the Invention) However, it is known that, for example, the frame member 3 is provided with high reflectance as in Patent Documents 1 to 3, and the vicinity of the light source in the kneading surface excessively becomes high in brightness, and brightness is generated. It is not uniform, so it becomes more difficult to visualize. Therefore, the present invention has been attempted to disclose a new frame member which can supply a large amount of light from a light source to a liquid crystal panel and which can suppress unevenness in luminance. (Means for Solving the Problem) 100137479 5 201232103 In the case where the frame member is provided with high reflectivity as in the prior art (see, for example, Patent Documents 1 to 3), the inventors excessively become near the light source in the kneading surface. The reason for the high brightness and the unevenness of the brightness is studied. As a result, for example, as shown in Fig. 7, the "reflectance 99% frame" is used to measure the shell width on the central vertical line orthogonal to the longitudinal direction of the end edge portion of the surface of the light source. It can be seen that if the peak of the brightness appearing near the light source of the central vertical line 鬲 is at the peak near the central portion of the central vertical line, the degree of the shell near the light source becomes too high, resulting in unevenness of the brightness of the entire surface. Therefore, the inventors of the present invention have further developed the present invention and completed the following invention. That is, the present invention discloses a frame member which is incorporated in an edge-light-emitting type liquid crystal display device, and includes a portion of the side wall portion which protrudes toward the inside and is provided on one or the entire surface of the back surface. a light reflecting surface having an average reflectance of 10% to 8 〇〇 nm of 10% or more, and when the frame member is incorporated into the liquid crystal display device, the surface is self-orthogonal to the surface of the light source. The maximum point brightness measured from the light source side end portion on the vertical line of the longitudinal direction of the edge portion to the length of only 5% of the entire length of the central vertical line is lower than the length of the above 5%. The maximum point brightness at a farther position. The frame member 3 of the present invention proposes a member of a liquid crystal display device of a group edge-light-emitting type, which has a portion in which a portion of the side wall portion protrudes toward the inside, and is a suitable example of the frame member described above. One part of the back surface or the whole society has a wavelength of ~ ̄ then the average reflectance of nm is 1 嶋 light reflection surface. 100137479 201232103 However, the frame member of the present invention is not limited to the frame member 3 as described above. For example, the area of 5 〇% of the back surface of the frame member is a light reflection surface having an average reflectance of 100% at a wavelength of 4 〇〇 to 8 〇〇 nm, and the remaining area of 5 〇 % is at a wavelength of 400 to 800 nm. When the average reflectance is 〇%, the conditions of the frame member of the present invention described above can be considered. (Effect of the Invention) When the liquid crystal display device is formed by the frame member of the present invention, the light is reflected from the light toward the frame member. Since the light from the light source can be supplied to the liquid crystal panel in a large amount, the brightness can be suppressed. The unevenness makes it possible to balance the brightness of the picture. [Embodiment] "The frame member which is an example of the embodiment of the present invention is referred to as "this frame member 3"). The system of the present invention is not limited to the embodiment described below. <This frame member 3 > This frame_piece 3 is based on the edge of the _ mode of the liquid crystal display illusion 2 亮 提 提 纽 亮 亮 亮 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如The protruding part 3a) the two parts ^^^? The light type means that the left and right side ends of the guide wire 6 and the lower side edge portion, and the plurality of light sources 5 are vacant on the straight line" 100137479 201232103 A configuration in which light is incident on the side surface of the light guide plate 6. The side member 3 is characterized in that it has a frame-like side wall portion such as a rectangular frame, and a portion partially protrudes inwardly. ^=3-like edge-lit type liquid crystal display device, in the display edge W from the front edge of the face where the light source 5 is disposed (for example, the length of the screen below the length of the fiscal line vertical line z cut light The maximum point brightness TP measured on the _ end portion to the area (also referred to as the area: ") which is only the position of the length of 5% of the length of the £ is less than the length of the above 5%. The maximum point brightness Tq measured on the far position (also referred to as "area Q"). The back side of the frame member 3 is When the partial or full surface is set to a light reflection surface having an average reflectance of 1% or more at a wavelength of ~800 nm, the brightness is measured in the region P on the central vertical line Z in the display screen. The peak value Τρ shown in Fig. 6 and Fig. 7. Since the peak value is higher than the maximum value Tq of the shell degree measured in the area q, the brightness near the light source becomes too high, resulting in uneven brightness of the entire surface of the knead surface. Therefore, it is important that the frame member 3 can make the luminance peak value Tp in the region P lower than the luminance maximum value Tq measured in the region Q. From this point of view, it is more preferable that the luminance peak value Tp in the region P is relatively The ratio of the luminance maximum value Tq measured in the region Q is 1.G or less, and further preferably 0.9 to ί. In the frame member 3, it is important that the self-view side (the front side of the liquid crystal panel 2) 100137479 8 201232103 砚 ' 其 部分 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面 背面Improve the brightness of the face. North and then 'If you consider the brightness of the face and the brightness For the suppression of homogenization, the portion or the entire surface of the back surface 3A is preferably a light reflection surface having a wavelength 働 to a fine average reflectance of 10 to 80%, wherein the ratio is 5% or less and further preferably _ or less. However, the area of 5〇% of the back surface 3A of the frame member 3 may be set to an average reflectance of a wavelength of 400 to 800 nm, and the remaining area of the light reflection surface may be an average of the length of the ship. The reflectance is set to 〇%. The shape of the frame member 3 is a side wall portion having a shape of a rectangular frame in a plan view, that is, a side wall portion having a frame shape, and a portion in which one of the side wall portions protrudes inward The job-specific limit m can be exemplified by a shape of a substantially L-shape having a protruding face portion 3a and a hanging edge portion 3b as shown in FIG. 2 when viewed from another side. For example, as shown in FIG. 2, in the case of having a substantially L-shaped shape having a protruding face % and a drooping edge adjacent to 3bb, the entire surface of the protruding face ^ and the sag side and U3b are the above-mentioned light reflecting surface. Moreover, the portion of the back surface of the protruding portion 3a and the hanging edge portion 3b may be protruded, and the entire surface of the back surface of the face portion may be the above-mentioned light reflecting surface, and a part of the back surface of the protruding surface portion is the above-mentioned The light reflecting surface can also be used. For example, the portion of the back surface 3A of the frame member 3 that is disposed in the space surrounded by the light source 5 (in other words, the portion that touches the light source 5 via the space connection 100137479 201232103) may be the light reflecting surface described above. The present frame member 3 is not particularly limited in its material 'which may be formed of a resin or a metal. Further, the frame member is usually colored in a plurality of colors, but the frame member 3 may be colored black or may be colored in other colors. As described above, one or the entire surface of the back surface 3a may be the light reflecting surface described above. The frame member 3 can also be fabricated by attaching a light-reflecting sheet to the back surface of the frame member after the production of a normal frame member, and can also be processed in such a manner that the back surface is shaped into a fine shape after the usual frame member is formed. And made a light reflecting surface. Further, a light reflecting surface may be formed on the back surface of the frame member by metal deposition. As a general method for producing a frame member, for example, particles of a resin composition are injected and filled in a cavity and injection molded. In this case, more specifically, it is preferable to form a frame-like frame (hereinafter also referred to as a flat panel display (FPD) fixing frame) having at least one protrusion or hole or groove for snap fit. For example, it can be produced in the following manner: The burning degree on the test piece of 1.5 mm thickness in the vertical burning test of the specification 1; 1 specification 94 is v_〇, and is not. A pellet composed of a resin composition of a ruthenium compound which is chemically bonded with a gas, a precursor, and a filament is sprayed into the cavity, and the FPD fixing frame is taken out from the cavity. In this case, in addition to the usual injection molding, injection molding: injection molding, gas-assisted injection molding, foaming including injection of a supercritical w body, inlay molding, mold (four) cloth formation, and separation Hot mold forming, rapid heating and cooling mold forming, two-color forming, sandwich secret, and ultra-high speed 100137479 10 201232103 Injection molding. Further, any one of the cold runner method and the hot runner method can be selected. When the light-reflecting sheet is attached to the back surface of the frame member to form the frame member 3, the light-reflecting sheet may be an organic or inorganic filler on the base resin of the resin sheet or a resin which is incompatible with the base resin. A light scattering reflector is produced using the difference between the refractive indices of the base resin and the formulations. Further, by forming a void in the inside of the sheet by stretching the resin sheet, light scattering reflection can be caused by the difference between the refractive index of the void and the base resin.

[Measurement and Evaluation Method] r First, the method for measuring the physical property values of the sample shank obtained in the examples and (4) will be described. (Light transmittance) The integrating sphere was mounted on a spectrophotometer ("U-4000", manufactured by Hitachi, Ltd.) to measure the transmittance with respect to light of 550 nm. Further, the photometer was set so that the reflectance of the alumina white plate was 100% before the measurement. (Reflectance): An integrating sphere was attached to a spectrophotometer ("11-4000", manufactured by Hitachi, Ltd.), and the reflectance of light with respect to a wavelength of 400 to 800 nm was measured. Moreover, Table i represents the average reflectance of light with respect to a wavelength of 400 to 800 nm. Furthermore, in the measurement, the photometer was set so that the reflectance of the emulsified whiteboard was 100%. (Brightness) The redundancy is calculated using the Brahman's unevenness meter (CA-2000, manufactured by KONICA MINOLTA Sensing Co., Ltd.) with a standard lens, a measurement distance im, a cumulative number of times of 16137479 14 201232103, and a pixel number tear setting. The measurement was performed to calculate 9 average brightness and overall average brightness of the surface. The 9-point average brightness phase 8 shows a bright average of the dots, and the overall average brightness of the face is the average of the brightness of the entire light-emitting surface. In all the measurements of the examples and the comparative examples, a liquid crystal display device (17 Inno LCD TV) constituted by the configuration shown in Fig. 4 - Fig. is used, and the liquid crystal was removed and used. The member other than the member (brightness enhancement A, cymbal, diffusion sheet, light guide plate, reflection sheet)' directly uses the initial state of the above display. Fig. 4 shows a schematic diagram of the front view of the Weijing TV, and Fig. 5 is a nucleus diagram of the frame 3 of the present invention.

Moreover, the maximum lighting measured in the area (also referred to as "area P") of the position of the length of the grip of the far-length body L only on the central vertical line 邛: 邛, 、, and ratio 5/. The maximum point brightness Tq measured in the area where the length is further moved (also referred to as "area q"). <Example 1> When the "frame member having a reflectance of 32%" was used, the 9-point average brightness of the display was raised to "5147.G", and the brightness unevenness was not expanded. Further, it is confirmed that the maximum brightness Tq measured in the area Q is larger than the maximum point brightness measured in the area ^. Moreover, the unevenness in brightness near the light source is not expanded. 100137479 15 201232103 In this case, as shown in FIG. 2, the frame member having a frame shape of 32% has a frame-shaped side wall portion (a hanging edge portion 3b) and a protruding surface portion 3a on the back surface of the protruding surface portion 3a. Overall, a sheet having a reflectance of 32% was attached to the initial frame member. "32% of the reflectance" is a mixture of COP (ZEONORRCY15, manufactured by Nippon Paint Co., Ltd.) and PP (NOVATEC ΕΑ9, manufactured by Japan Polypropylene Co., Ltd.) at a ratio of 75:25, and is supplied to a heating of 2 〇〇〇c. The extruder was kneaded at 20 (TC) using the extruder, and then the resin composition in a molten state was extruded into a sheet shape by a τ-shaped mold to have a thickness of 165. <Example 2> In the frame member with a reflectance of 57%, the 9-point average brightness of the display is raised to "5268.9", and the brightness unevenness is not expanded. Further, it is confirmed that the area Q is larger than the maximum point brightness Tp measured in the area p. The maximum spot brightness Tq measured in the middle is larger. In addition, the uneven brightness near the light source is not expanded.
