Abstract

An embodiment of the invention discloses a blue phase liquid crystal panel, a blue phase liquid crystal device and a manufacture method of the blue phase liquid crystal panel and belongs to the technical field of display. The technical problem that driving voltage required by the existing blue phase liquid crystal is high is solved. A driving electrode is a wall-shaped electrode, and a wrinkle structure is arranged on the surface of the wall-shaped electrode. The wall-shaped electrode can be formed by hard electric conduction photoresist or flexible electric conduction photoresist. The blue phase liquid crystal panel, the blue phase liquid crystal device and the manufacture method of the blue phase liquid crystal panel are applied to modification of the driving electrode.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a blue-phase liquid crystal panel, a device and a manufacturing method thereof. Background technique [0002] With the continuous development of display technologies, liquid crystal panels (Liquid Crystal Display, LCD) have occupied a dominant position in the field of flat panel displays. Blue-phase liquid crystal has the advantages of fast response speed and wide viewing angle, and is a promising liquid crystal display material. However, the blue phase liquid crystal usually needs to be driven by a horizontal electric field, and the required driving voltage is relatively high. [0003] At present, for the problem of high driving voltage of blue-phase liquid crystals, a common solution is to use finger electrodes. In addition, there are wall-shaped electrodes, protruding electrodes, trapezoidal electrodes, corrugated electrodes, etc., but these solutions are still ...
