Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 低駆動電圧かつ高電荷保持率のホログラフィ ック高分子分散液晶光学素子を提供する。 【解決手段】 色素材料を含有した高分子樹脂中に液晶 材料が滴状に規則的に配列した調光層を、電極層を有す る透明性基板と電極層を有する光吸収基板で挟持した構 造であり、前記色素材料が高分子樹脂と光重合による共 重合により固定化されていることを特徴とする液晶光学 素子。 (57) [Problem] To provide a holographic polymer dispersed liquid crystal optical element having a low driving voltage and a high charge retention rate. SOLUTION: This structure has a structure in which a light control layer in which liquid crystal materials are regularly arranged in a drop shape in a polymer resin containing a dye material is sandwiched between a transparent substrate having an electrode layer and a light absorbing substrate having an electrode layer. A liquid crystal optical element, wherein the pigment material is fixed by copolymerization with a polymer resin and photopolymerization.
