Abstract
A liquid crystal device in one aspect of the present disclosure includes a liquid crystal layer, and an electrode layer configured to form an electric field in the liquid crystal layer. The liquid crystal layer includes a liquid crystal composition in which an organic compound having a property of inhibiting a polymerization reaction caused by light action is added to a liquid crystal mixture as a polymerization inhibitor.
Claims19
A liquid crystal device comprising:
- a liquid crystal layer;
- and
- an electrode layer configured to create an electric field in the liquid crystal layer,
- wherein the liquid crystal layer includes a liquid crystal composition in which an organic compound having a property of inhibiting a polymerization reaction caused by light action is added to a liquid crystal mixture as a polymerization inhibitor.
A liquid-crystal-type spatial phase modulator comprising:
- a transparent solid material layer configured to receive an input of light;
- a transparent electrode layer disposed below the solid material layer;
- a first alignment film layer disposed below the transparent electrode layer;
- a liquid crystal layer disposed below the first alignment film layer;
- a second alignment film layer disposed below the liquid crystal layer;
