Title:
LIQUID CRYSTAL ELEMENT, DISPLAY PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/220299
Kind Code:
A1
Abstract:
The present invention provides a novel liquid crystal element that is exceptionally reliable and easy to use. Further provided is a novel display panel which is extremely easy to use and highly reliable. The liquid crystal element (75) comprises a first electrode (51), a second electrode (52), and a layer (52) containing a liquid crystal material, the second electrode being arranged so as to form, with the first electrode, an electric field that crosses the layer containing the liquid crystal material. When the electric field is in a first state, the layer containing the liquid crystal material scatters incident light at a first scattering intensity, and when the electric field is in a second state, the layer containing the liquid crystal material scatters incident light at a second scattering intensity. The second scattering intensity is larger than the first scattering intensity. The layer containing the liquid crystal material contains a liquid crystal material and a polymeric material, and the layer containing the liquid crystal material is stabilized by the polymer. The polymeric material is a copolymer of a polyfunctional monomer and a monofunctional monomer, the polyfunctional monomer has a benzoic acid phenyl skeleton, and the monofunctional monomer has a cyclohexylbenzene skeleton.
