Embodiment Construction

[0043] The present invention utilizes the design of the double-sided electrodes, so that a transverse electric field and a vertical electric field can be generated in the liquid crystal cell. Wherein, the transverse electric field is used to make the liquid crystal cell display a good bright state, and the vertical electric field is used to make the liquid crystal cell display a good dark state. The liquid crystal display device according to the present invention will be described in detail below with specific examples in conjunction with the accompanying drawings, but the provided examples are not intended to limit the scope of the present invention, and the description of the structure and operation is not intended to limit it. The sequence of execution, any recombination of components to produce devices with equivalent functions are within the scope of the present invention. The accompanying drawings are for illustration purposes only and are not drawn to original scale.

Abstract

The invention provides a liquid crystal display device which has blue phase liquid crystal. The liquid crystal display device comprises a plurality of electrodes. In the invention, at least one pair of electrodes is arranged on one side of the blue phase liquid crystal to supply a transverse electric field to drive the macromolecular stabilized positive type blue phase liquid crystal for increasing the penetration rate of the light and controlling the bright state of the liquid crystal display device; and at least one pair of electrodes are arranged on the opposite sides of the blue phase crystal liquid to supply a vertical electric field, so the macromolecular stabilized positive type blue phase liquid crystal has excellent optical isotropy in a dark state and light leak in the dark state is reduced.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and in particular to a liquid crystal display device with a blue phase liquid crystal. Background technique [0002] Due to the advantages of low-voltage operation, no radiation scattering, light weight, and small size, liquid crystal display devices have been regarded as the mainstream of display device development in recent years. Known liquid crystal display devices generally use nematic liquid crystals to change the polarization direction or polarization state of transmitted light, and use polarizers to convert the changes into light and dark contrast for display, so the required response time is relatively long. [0003] On the other hand, the blue phase (blue phase) liquid crystal material has a short response time, and its existence has begun to be paid attention to. The blue phase is a liquid crystal phase between isotropic and cholesterolic phases. The blue phase itself can be...
