Abstract

The invention discloses a liquid crystal medium of a liquid crystal display panel. A liquid crystal compound based on a tetracene derivative is doped in a liquid crystal mixture, so that the liquid crystal compound based on the tetracene derivative is bonded on the alkenyls of diluent liquid crystal molecules to prevent the alkenyls of the diluent liquid crystal molecules from reacting with a polymerizable compound, thus inhibiting the bonding between the alkenyls of the diluent liquid crystal molecules and the polymerizable compound. The liquid crystal medium can solve the problem of image retention caused by the bonding between polymerizable compound and the alkenyl of the diluent liquid crystal molecules.

Description

technical field [0001] The present invention relates to a liquid crystal layer of a liquid crystal panel, in particular to a liquid crystal medium of a liquid crystal panel, which can improve the problem of image sticking in the liquid crystal screen. Background technique [0002] In the manufacturing process of liquid crystal display panels, there will inevitably be some residues in the liquid crystal layer of patterned vertical alignment (PVA) mode liquid crystal display panels or wide-area vertical alignment (High Vertical Alignment, HVA) mode liquid crystal display panels. A polymerizable compound that is bonded to the alkenyl group of the diluent liquid crystal molecule. The polymerizable compound is a liquid crystal reactive monomer (Reactive Monomer, RM). After driving for a long time, the deterioration of the charged polymerizable compound will generate charged ions, and then the distribution of these charged polymerizable compounds and charged ions will gradually c...
