    • The present invention relates to a light guide panel, wherein it is an aim of the present invention to provide a light guide panel for a backlight unit having an integrated optical sheet, as well as a backlight unit comprising the light guide panel, in which an optical pattern formed on a rear surface of the light guide panel is prevented from being displayed on a front surface of an LCD. To accomplish the aim, the light guide panel of the present invention is arranged behind the integrated optical sheet, the rear surface of which has a light-condensing portion having a plurality of prism elements, and the front surface of which has an anisotropic diffusing portion having a plurality of diffusing elements, wherein a lower pattern is formed on the rear surface facing a reflecting panel so as to prevent the pattern on the rear surface of the light guide panel from being displayed on the front surface of the LCD, wherein the lower pattern has a plurality of embossed pattern elements arranged at a predetermined spacing to disperse light.
    • 导光板技术领域本发明涉及一种导光板,其目的在于提供一种具有集成光学片的背光单元的导光板,以及包括导光板的背光单元,其中, 形成在导光板的后表面上的光学图案被防止显示在LCD的前表面上。 为了达到上述目的,本发明的导光板配置在集成光学片的后方,其背面具有聚光部,该聚光部具有多个棱镜元件,前表面具有各向异性扩散部 具有多个漫射元件,其中在面向反射面板的后表面上形成下图案,以防止导光板背面上的图案显示在LCD的前表面上,其中较低的 图案具有以预定间隔布置以分散光的多个压花图案元件。
