Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a supporting diffusion plate, and more particularly to a supporting diffusion plate applied to a liquid crystal display. [Prior technology] Because the Liquid Crystal Display (LCD) has an all-plane and thin body, it saves space and weight, plus a large display range, no flicker on the daytime, low power consumption, low electromagnetic wave radiation, The advantages of low heat radiation and so on make it gradually replace the traditional Cathode Ray Tube (CRT) display as the standard equipment of the computer. For large-size LCD monitors or TV (τν) monitors that are generally larger than 20 inches, a support plate is required above the light source of the backlight module to carry the weight of the large-size display panel, and to strengthen the main structure of the liquid crystal display. . The configuration of the support plate can avoid the bending and deformation of the large-sized display panel, thereby affecting the display quality of the liquid crystal display. Please refer to FIG. 1, which is an exploded view of a conventional liquid crystal display. In FIG. 1, the liquid crystal display 1000 includes at least a liquid crystal display panel 110 and a direct type backlight module 120. The backlight module 120 can provide uniform and sufficient light to the liquid crystal display panel 110 to perform better display quality. The backlight module 120 includes an optical sheet consisting of a prism and a diffuser sheet, a diffuser plate 112, a diffuser plate 113, a reflective sheet Π5, and a plurality of light sources. 114 and a lamp holder 116. The light source 1 1 4 is a plurality of cold cathode tubes arranged in parallel, and the lamp holder 116 is used to place a plurality of light sources 11 4. In light source 丨 i 4

Description of the invention (2) A reflecting sheet 11 5 is arranged below to reflect light. The support plate 3 is disposed on the light source 114 to support the weight of the liquid crystal display panel 110 and strengthen the main structure of the liquid crystal display 100. The optical sheet 111 and the diffusion plate 112 are disposed on the supporting plate 11 3 'to uniformly expand and guide the light emitted from the light source 114 to the liquid crystal display panel 110. However, most of the current supporting plate 113 is made of plastic materials such as acrylic (PMM A). Due to the relatively weak stress strength of the material nature of acrylic, 'If the support plate is to bear the weight of the entire display panel 110,' it must be achieved with a considerable thickness of acrylic. For example, the thickness of the general support plate 113 is about 8 mm (mm) to 10 mm (mm). In addition, spacer pins are generally used to reinforce its support force to avoid warp. Furthermore, since the acrylic material is gradually yellowed after being used for a period of time, the supporting plate 113 is more likely to yellow and become brittle after being used for a period of time. In addition, due to the poor heat resistance of the acrylic material, when the cold cathode tube used as the light source 114 emits light, the high 'temperature' generated by the electrode heating is likely to cause the support plate 113 and the optical sheets ill and the diffusion plate thereon. 11 2 and other components are deformed due to heat, which affects the display quality of the entire liquid crystal display and reduces the production yield. … [Summary of the Invention] In view of this, the object of the present invention is to provide a support diffusion plate that is formed by using an atomized glass, which has the function of diffusing light and supporting the display panel at the same time, and can avoid thermal distortion And yellowing. Replace the conventional support plate and diffuser plate to reduce the number of modules
