光调制元件

Abstract

The invention relates to a light modulation element comprising a cholesteric liquid crystalline medium sandwiched between two substrates (1), each provided with an electrode structure (2), wherein at least one of the substrates is additionally provided with an alignment layer (3) which is provided with a photoresist pattern consisting of periodic substantially parallel stripes (4). The invention is further related to a method of production of said light modulation element and to the use of said light modulation element in various types of optical and electro-optical devices, such as electro-optical displays, liquid crystal displays (LCDs), non-linear optic (NLO) devices, and optical information storage devices.
本发明涉及一种光调制元件,其包含夹在两个基板(1)间的胆甾醇型液晶介质,各基板提供有电极结构(2),其中该基板中的至少一个额外提供有配向层(3),其提供有由周期性基本上平行的条带组成的光刻胶图案(4)。本发明另外涉及一种制造所述光调制元件的方法,和所述光调制元件在各类光学和电光器件(诸如电光显示器、液晶显示器(LCD)、非线性光学(NLO)器件和光学信息储存器件)中的用途。
