Abstract

The embodiment of the invention provides a blue phase liquid crystal panel and a liquid crystal display applying the same, relates to the field of liquid crystal display technology and solves the problem that blue phase liquid crystal in the existing panel cannot be driven by a vertical electrical field to realize gray scale display. The blue phase liquid crystal panel comprises a first substrate, a blue phase liquid crystal layer and a second substrate, wherein the first substrate comprises a lower polarizer, a first quarter-wave plate, multiple substrate reflector plates, an array substrate and a pixel electrode; the second substrate comprises a common electrode, a second quarter-wave plate, an upper polarizer, and also comprises multiple middle reflector plates in the blue phase liquid crystal layer; absorption axes of the lower polarizer and the upper polarizer are in parallel with each other or perpendicular to each other; optical axes of the first quarter-wave plate and the second quarter-wave plate are in parallel with each other, and an included angle between each optical axis and a corresponding absorption axis of the upper polarizer and the lower polarizer is 45 degrees; an included angle formed by the middle reflector plates and the pixel electrode is 45 degrees, and projections of the middle reflector plates on the first quarter-wave plate are in end-to-end connection and coincide with the substrate reflector plates.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a blue phase liquid crystal display panel and a liquid crystal display using the same. Background technique [0002] At present, in order to improve the display quality of liquid crystal displays, blue-phase liquid crystal materials with fast response characteristics are gradually being paid attention to. The blue phase liquid crystal is a phase state with special properties in liquid crystals. It has an isotropic refractive index when no voltage is applied, and it changes into an anisotropic refractive index when a voltage is applied. With the change of the applied voltage , the anisotropy of the refractive index will also change. The display panel using the blue phase liquid crystal can greatly improve the response speed, and does not need alignment treatment. [0003] Since the blue phase liquid crystals are all positive type liquid crystals, the existing disp...
