Liquid crystal medium mixture and liquid crystal display using liquid crystal medium mixture

Abstract

The invention provides liquid crystal medium mixture and a liquid crystal display using the liquid crystal medium mixture. The liquid crystal medium mixture comprises at least one kind of anisotropic liquid crystal materials and one kind of polymerizable monomer which can be subjected to polymerization reaction under the irradiation of ultraviolet light; and the polymerizable monomer accounts for 0.1 to 1 percent based on the total weight of the liquid crystal medium mixture. According to the liquid crystal medium mixture and the liquid crystal display using the liquid crystal medium mixture, one kind of the polymerizable monomer which can be subjected to polymerization reaction under the irradiation of ultraviolet light, and an appropriate proportion are adopted, so that polymer prominence which is small in size and high in uniformity can be obtained through polymerization reaction, and the phenomena of poor liquid crystal alignment effect and dark-state bright point of a liquid crystal panel can be avoided; and therefore, the liquid crystal panel is high in response speed, high contrast ratio can be guaranteed, and the stable mass production can be realized.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal medium mixture and a liquid crystal display using the same. Background technique [0002] The liquid crystals used in TN (Twisted nematic) or STN (Super twisted nematic) liquid crystal displays are positive liquid crystals, and the long axis of liquid crystal molecules is parallel to the surface of the substrate when no power is applied. The alignment direction of the liquid crystal molecules on the surface of the substrate is determined by the rubbing direction of the alignment layer (Alignment layer, usually made of Polyimide). In a continuous twisted arrangement. When a voltage is applied, the long axes of the liquid crystal molecules tend to align along the direction of the electric field. The disadvantage of TN / STN liquid crystal displays is that the viewing angle is small, and the brightness difference and color difference are serious under large viewi...

Problems solved by technology

Since the existing liquid crystal media generally contain alkenyl compounds, it is beneficial to obtain low rotational viscosity, thereby improving the response of the liquid crystal medium. Improve the response of the liquid crystal medium, and the alkenyl compound contained in the liquid crystal medium is easy to affect the reaction polymerization of the polymerizable monomer, thereby affecting the alignment of the liquid crystal medium, so it is necessary to select a suitable polymerizable monomer to make the uniformity of the polymer Good, strong alignment and fast response
