Abstract

The invention discloses a blue phase liquid crystal display device and a manufacturing method thereof, and the method comprises the following steps: configuring a first substrate opposite to and parallel with a second substrate, wherein the first substrate comprises a first electrode, and the second substrate comprises a second electrode; configuring a blue phase liquid crystal layer between the first substrate and the second substrate, wherein the blue phase liquid crystal layer comprises homocercal blue phase liquid crystals and polymer monomers; applying pressure on the first electrode andthe second electrode to form a vertical electric field in the blue phase liquid crystal layer; and enabling a light source to irradiate in the blue phase liquid crystal layer to carry out polymerization on the polymer monomers to generate macromolecule stabilized homocercal blue phase liquid crystals. In addition, a blue phase liquid crystal display device is disclosed in the invention.

Description

technical field [0001] The present invention relates to a display device, and in particular to a blue phase liquid crystal display device. Background technique [0002] In recent years, in order to improve the display quality of liquid crystal displays, blue phase liquid crystal materials with fast response characteristics have gradually attracted attention. The blue phase (Blue Phase) is a state between the isotropic state (Isotropic) and the cholesterol (Cholesteric) phase. The liquid crystal phase exists in a very narrow temperature range, only about 1°C. [0003] The blue phase has three different phases, namely the first blue phase (BP I), the second blue phase (BP II) and the third blue phase (BP III), wherein the first blue phase and the second blue phase are cubic structure (cubic), and the third blue phase is amorphous (amorphous) structure, and the temperature of existence is the highest one among the three phases. [0004] Figure 1a and Figure 1b It is a sche...
