Abstract
The present invention provides a liquid crystal additive, a liquid crystal composition and a liquid crystal panel thereof. The liquid crystal additive of the present invention has a higher clear point, so that adding the liquid crystal additive into a liquid crystal composition of a liquid crystal panel can omit the process of forming alignment films to reduce manufacturing costs and time of liquid crystal panels; meanwhile, the MURA phenomenon due to the different effects of liquid crystal molecules and liquid crystal reactive monomers on alignment films is avoided, so as to improve the uniformity of liquid crystal panel.
Claims7
