Title:
METHOD FOR MANUFACTURING POLYMER DISPERSED LIQUID CRYSTAL DISPLAY ELEMENT, AND POLYMER DISPERSED LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/230030
Kind Code:
A1
Abstract:
The present invention, in a method for manufacturing a polymer dispersed liquid crystal display element, identifies a precise manufacturing condition for obtaining a uniform dispersion state, a uniform transparent state, and a uniform drive voltage state, to obtain a polymer dispersed liquid crystal display element having those uniform properties. A highly uniform polymer dispersed liquid crystal display element can be obtained by irradiating a liquid crystal material and a light-conditioning layer formation material containing a polymerizable composition with light under a specific ultraviolet ray irradiation condition to polymerize the polymerizable composition.
