    • The present invention relates to a manufacturing method of an optical film, an optical film manufactured by the same, and a liquid crystal display including an optical film. The manufacturing method of an optical film includes the steps of: melting and extruding a non-liquid crystalline thermoplastic resin; and enabling the melted and extruded non-liquid crystalline thermoplastic resin to pass into the space between a first forming roll and a second forming roll. The surface temperatures of the first and second forming rolls are equal to or less than a glass transition temperature (Tg) of the thermoplastic resin. Different shear forces are generated on the surface of the film and the inside of the film according to the operation of the first and second forming rolls to apply a tilt angle to the film. The non-liquid crystalline thermoplastic resin is extruded to form a multi-layered structure.
    • 本发明涉及一种光学膜的制造方法,由其制造的光学膜以及包括光学膜的液晶显示器。 光学膜的制造方法包括以下步骤:熔融并挤出非液晶性热塑性树脂; 并使熔融挤出的非液晶热塑性树脂进入第一成形辊和第二成形辊之间的空间。 第一成形辊和第二成形辊的表面温度等于或小于热塑性树脂的玻璃化转变温度(Tg)。 根据第一和第二成形辊的操作,在膜的表面和膜的内部产生不同的剪切力,以向膜施加倾斜角。 将非液晶热塑性树脂挤出以形成多层结构。

    • PURPOSE: An optical sheet and a backlight unit including the same are provided to solve the increasing problem of the surface resistance value which is caused by a protective film detachment because of excellent surface hardness and an anti-static effect even without a protective film. CONSTITUTION: Base material layers(120a,120b) are laminated on both sides of a brightness increase film(110). Surface layers(130a,130b) are laminated on the base material layer. The thickness ratio of the base material layer and the surface layer is 1:1 or 20:1. The surface layer has a surface hardness of B-2H which is measured by an ASTM D3363. The weight ratio of a thermoplastic resin and an anti-static agent is 1:0.01 or 1:1 on the surface layer.

    • A light guide panel comprising a step structure for a back light unit of a TFT-LCD is provided to obtain the same brightness by having high brightness and excellent uniformity although at least one sheet of a prism sheet or a diffusion sheet is omitted. A light guide panel having a step structure for a back light unit of a TFT-LCD includes a light incident surface(210), a front surface(230), and a rear surface(220). A light from a light source is inputted to the light incident surface. The front surface emits the light. The rear surface has a cross-section structure mixed with a geometric reflective body and a plurality of step shapes for reflecting the light to the front surface. The plurality of step shapes are parallel to the front surface. The plurality of step shapes are constructed such that a distance from the front surface becomes shorter as the light becomes farther from the side surface.
