    • A light guide plate and a liquid crystal display device having the same. The light guide plate is disposed upstream of a liquid crystal panel to refract light supplied through an edge thereof, toward the liquid crystal panel. In the light guide plate, a plate body is disposed at a side of a light source for supplying light when a supply voltage is applied. A plurality of pyramidal diffusing elements are arrayed in a predetermined pattern on a surface of the plate body. Each of the diffusing elements is rotated clockwise or counterclockwise about an axis extending through a vertex of the diffusing element perpendicularly to the surface of the plate body so that an edge of the diffusing element facing a reference line connecting a central point of the light source to a central point of the plate body is angled 10° to 35° about the reference line.
    • 导光板和具有该导光板的液晶显示装置。 导光板配置在液晶面板的上游侧,将通过其边缘供给的光折射到液晶面板。 在导光板中,当施加电源电压时,板体设置在用于供应光的光源的一侧。 多个金字塔形扩散元件以预定图案排列在板体的表面上。 每个扩散元件围绕延伸穿过漫射元件的顶点的轴线顺时针或逆时针旋转,垂直于板体的表面,使得漫射元件的边缘面向连接光源的中心点的参考线, 板体的中心点围绕参考线倾斜10°至35°。

    • A method for fabricating a liquid crystal display device comprising the steps of forming a patterning layer to be patterned on the a substrate; forming a protective layer on the patterning layer, the protective layer being provided to prevent the occurrence of a poor pattern; depositing a photoresist layer on the protective layer; patterning the photoresist layer to form a patterned photoresist layer; sequentially removing the protective layer and the patterning layer using the patterned photoresist layer as an etching mask; and removing the patterned photoresist layer. The method facilitates the formation of a smooth passivation layer surface since there is no step between the drain and pixel electrodes. As a result, constant brightness and high contrast can be obtained from a TFT-LCD device which is fabricated by the method of the present invention. A film having a low friction coefficient is also used as a protective layer to prevent the formation of a poor pattern, and thus a desired pattern can be obtained.
    • 一种制造液晶显示装置的方法,包括以下步骤:在基板上形成待图案化的图案化层; 在所述图案化层上形成保护层,所述保护层被设置为防止发生不良图案; 在保护层上沉积光致抗蚀剂层; 图案化光致抗蚀剂层以形成图案化的光致抗蚀剂层; 使用图案化的光致抗蚀剂层作为蚀刻掩模顺序地去除保护层和图案形成层; 并去除图案化的光致抗蚀剂层。 该方法有助于形成平滑的钝化层表面,因为在漏极和像素电极之间没有步骤。 结果,可以从通过本发明的方法制造的TFT-LCD装置获得恒定亮度和高对比度。 也可以使用具有低摩擦系数的膜作为保护层,以防止形成不良图案,从而可以获得所需的图案。
