Problems solved by technology
According to the knowledge of liquid crystal electricity, the torque generated by the applied voltage is the driving force for the rotation of liquid crystal molecules, so the director of IPS liquid crystal molecules is basically consistent with the direction of the electric field lines, which will inevitably cause the liquid crystal molecules at the edge of the electrode to be inclined due to the arrangement of the electric field lines phenomenon, so that the transmittance at the edge of the electrode becomes low, so it is necessary to provide a method to solve the above problems

Abstract
The invention provides a liquid crystal polymer and a liquid crystal display panel. The liquid crystal polymer comprises a liquid crystal and an acrylic monomer polymer uniformly mixed with the liquid crystal, wherein the acrylic monomer polymer comprises two or more than two monomer polymers; the monomer polymer is ethylene glycol dimethacrylate with a molecular formula of CH2=C(CH3)COOCH2CH2OCOC(CH3)=CH2, or the monomer polymer is acrylic monomer methyl methacrylate with a molecular formula of CH2C(CH3)COOCH3. According to the liquid crystal display panel provided by the invention, due to a fact that the liquid crystal of the liquid crystal display panel is the liquid crystal polymer, when an electric field is applied, due to the existence of a polymer network, the directors of liquid crystal molecules at an electrode edge are all parallel to griddings, and an oblique phenomenon cannot appear.
Description
technical field [0001] The invention belongs to liquid crystal display technology, in particular to a liquid crystal polymer and a liquid crystal display panel. technical background [0002] Liquid crystal display modes mainly include TN (Twisted Nematic, twisted nematic), VA (Vertical Alignment, vertical alignment technology), IPS (In Plane Switching plane control mode) and other display modes. IPS display mode is characterized by its excellent viewing angle characteristics, dynamic The clarity and color reproduction effect make it an ideal display technology for TFT-LCD for TV. [0003] IPS is a display technology in which liquid crystal molecules rotate in a plane to achieve brightness control. According to the knowledge of liquid crystal electricity, the torque generated by the applied voltage is the driving force for the rotation of liquid crystal molecules, so the director of IPS liquid crystal molecules is basically consistent with the direction of the electric field...
