Liquid crystal display device, and a method of manufacturing the same

Abstract

The present invention provides a liquid crystal display device, which comprises: cholesteric liquid crystals and polymer fragments. By adding polymer fragments, the upper and lower substrates of the liquid crystal display device of the present invention may control the alignment of the liquid crystals and have excellent electro-optical characteristics without the use of an alignment film; furthermore, the polymer fragments are modified with a vertical alignment agent, DMOAP to form a radial structure so as to improve the contrast. The present invention also provides a method for preparing a liquid crystal display device in a simple way, so that the liquid crystal display device has the electro-optical characteristics of high contrast, low threshold voltage, and fast response time.
