摘要： A hologram diffuser for a liquid crystal display wherein a resin layer with a desired thickness is formed on an upper substrate. A hologram pattern is formed in the resin layer using a hologram plate. A smoothing layer with a desired thickness is formed on the hologram layer provided with the hologram pattern. Accordingly, it is possible to assure a wide visual angle and realize a high picture quality.

摘要： A liquid crystal display (LCD) realizes a high brightness by using cholesteric liquid crystal (CLC) in a color filter and a polarizer, and improves viewing angles by using a hologram diffuser. The LCD includes a back light unit to produce and supply light, and a collimating sheet to collimate the light supplied by the back light unit. A CLC polarizer transmits left-circularly polarized light from the collimating sheet, and reflects other light. A lower substrate is disposed above the CLC polarizer, and an upper substrate is disposed above the lower substrate and includes a holographic diffuser which diffuses light without altering a polarization of the light. A liquid crystal layer is disposed between the lower substrate and the upper substrate, and a color filter layer which transmits only predetermined wavelengths of light is also disposed between the lower substrate and the upper substrate. An upper linear polarizer is located above the upper substrate. Accordingly, the LCD provides enhanced viewing angles via the holographic diffuser. Also, the LCD realizes high brightness via the CLC diffuser and a CLC color filter layer.

摘要翻译：液晶显示器（LCD）通过在滤色器和偏振器中使用胆甾醇型液晶（CLC）实现高亮度，并且通过使用全息图扩散器来改善视角。 LCD包括产生和供应光的背光单元和用于准直由背光单元提供的光的准直片。 CLC偏振器从准直片发射左圆偏振光，并反射其他光。下基板设置在CLC偏振器上方，并且上基板设置在下基板上方，并且包括在不改变光的偏振的情况下漫射光的全息漫射器。在下基板和上基板之间设置液晶层，并且在下基板和上基板之间也设置仅透过预定波长的光的滤色器层。上线偏振器位于上基板上方。因此，LCD通过全息漫射器提供增强的视角。此外，LCD通过CLC扩散器和CLC滤色器层实现高亮度。

摘要： Disclosed is a method for forming a pattern of a LCD device using a printing process, in which additive for detachment corresponding to detachment accelerant is coated in a groove of a cliché filled with ink, thereby easily transferring ink to a layer to be processed. A surface of the layer to be processed is processed chemically or physically to enhance an adhesive force with the ink.
