Problems solved by technology

[0004] Since the pixel electrodes and the common electrodes used to form the horizontal electric field in the blue-phase liquid crystal display device are located on the array substrate, the electric field lines formed between the pixel electrodes and the common electrodes need to penetrate the passivation layer, and the passivation layer will affect the electric field strength. weakening

The blue phase liquid crystal display device is used for displaying an image.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a blue-phase liquid crystal display device and a manufacturing method thereof. Background technique [0002] Blue phase liquid crystal is a phase state with special properties in liquid crystal. When no voltage is applied, the blue-phase liquid crystal has an isotropic refractive index, and the light cannot pass through the display panel, forming a dark field; when a voltage is applied, the blue-phase liquid crystal has an anisotropic refractive index, birefringence occurs, and the light can pass through It penetrates the display panel to realize light transmission, and the anisotropy of the refractive index of the blue phase liquid crystal changes with the applied voltage, and the light transmittance can be adjusted by adjusting the voltage. The display device adopting the blue phase liquid crystal can greatly improve the response speed, and does not need alignment treatment. ...
