摘要： The present invention relates to an optical sheet and an LCD apparatus using the same. An LCD apparatus according to the present invention comprises an LCD panel to display a picture thereon; a lamp unit emitting light; a light guide plate to guide the light from the lamp unit toward the LCD panel evenly; an optical sheet provided between the LCD panel and the light guide plate and including a condensing layer condensing the light from the light guide plate on the LCD panel, and a reflective polarizing layer attached to the surface of the condensing layer facing the LCD panel and selectively transmitting and reflecting the light condensed by the condensing layer. With this configuration, the present invention provides an optical sheet and an LCD apparatus using the same, in which a bright-line is decreased, brightness are enhanced, and the optical sheet is prevented from shrinking.
摘要翻译：本发明涉及一种光学片及使用其的液晶显示装置。根据本发明的LCD装置包括：LCD面板，用于在其上显示图像; 发射光的灯单元; 导光板，用于将来自灯单元的光均匀地引向LCD面板; 设置在LCD面板和导光板之间的光学片，包括聚集来自LCD面板上的导光板的光的聚光层和附着在面向LCD面板的聚光层的表面的反射偏振层，并且选择性地透射和反射由聚光层冷凝的光。采用这种结构，本发明提供一种光学片和使用该光学片的LCD装置，其中亮线减小，亮度提高，防止光学片收缩。
