Title:
ELECTRICAL DISPLACEMENT MATERIAL, OPTICAL ELEMENT USING SAME, MICRO LENS ARRAY, AND METHOD OF DEVELOPING OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2020/138242
Kind Code:
A1
Abstract:
Provided are an electrical displacement material with reduced driving voltage, and technology for applying same. An optical element is developed by placing, between a first electrode and a second electrode, an electrical displacement material obtained by adding an ionic liquid having a negative ion transport number of at least 0.4 at 25 °C, or an ionic surfactant having a negative ion transport number of at least 0.2 at 25 °C, to a gel-like high molecular material. In such optical element, the level of applied voltage that deforms the electrical displacement material is reduced, and with the reduced voltage being applied, an optical scatter body is formed on the surface of the first electrode or the second electrode.
