| abstract |
The invention relates to a light modulation element, preferably exploiting the flexoelectric effect 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 provided with a photoresist pattern consisting of periodic substantially parallel stripes (3) which is additionally provided with an alignment layer (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. |
