Abstract: The viewing angle of a Liquid Crystal Display (LCD) apparatus is expanded by means of a sampled light redirecting layer, In one embodiment, the sampled light redirecting layer is formed as a compensation layer disposed between a top polarizing plate and the rest of a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal layer interposed therebetween. The compensation layer includes at least two optical path changing patterns disposed in interleaved manner. The two optical path changing patterns have different refractive indexes. As a result of the different refractive indices and shapes of the at least two different optical path changing patterns some of the light rays sampled out of the output of the rest of a liquid crystal display panel are directed in a first direction by means of reflection or refraction and some are directed in a different second direction, thereby improving a side visibility of the display apparatus.

Abstract translation: 液晶显示器（LCD）装置的视角通过采样的光重定向层扩展。在一个实施例中，取样的光重定向层形成为设置在顶部偏振片和液体的其余部分之间的补偿层 晶体显示面板具有第一基板，第二基板和插入其间的液晶层。 补偿层包括以交错方式设置的至少两个光路改变图案。 两个光路改变图案具有不同的折射率。 由于至少两个不同光路改变图案的不同折射率和形状的结果，从液晶显示面板的其余部分的输出中采样的一些光线通过反射或第二方向被引向第一方向 折射，一些指向不同的第二方向，从而提高显示装置的侧面可视性。
