LIQUID CRYSTAL DISPLAY ELEMENT

PROBLEM TO BE SOLVED: To provide a liquid crystal display element applicable for such purposes requiring high transmissivity, particularly a transmissive liquid crystal display device, and achieving a novel display medium.SOLUTION: The liquid crystal display element includes a first transparent insulation substrate having a pixel electrode and a second transparent insulation substrate having a common electrode, disposed to oppose to each other at a given interval, and a light-control layer comprising a polymer matrix and a liquid crystal composition disposed between the two substrates or on the first transparent insulation substrate having a pixel electrode and a common electrode. The polymer matrix has a nano cavity in a size of 20 to 400 nm; and the liquid crystal composition comprises a compound represented by formula (G). In the formula, Rrepresents an alkyl group or the like; Aand Aeach independently represent a cyclohexylene ring, a phenylene ring or the like; Zrepresents a single bond, -CH=CH- or the like; and nrepresents an integer of 2 to 4.SELECTED DRAWING: None 【課題】高い透過性が必要とされる用途、特に透過型の液晶表示装置に適用可能で、新規な表示媒体を実現できる液晶表示素子の提供。【解決手段】画素電極を有する第一の透明絶縁基板と、共通電極を有する第二の透明絶縁基板とを一定の間隔で対向に配置し、該二つの基板間又は、画素電極と共通電極を有する第一の透明絶縁基板上に、ポリマーマトリクス及び液晶組成物を含む調光層を配置し、前記ポリマーマトリクスが２０〜４００ｎｍのナノ空隙を有し、該液晶組成物として、式（Ｇ）で表される化合物を含有する液晶表示素子。（ＲＧ１はアルキル基等；ＡＧ１及びＡＧ２は各々独立にシクロヘキシレン環あるいはフェニレン環等；ＺＧ１は単結合、−ＣＨ＝ＣＨ−等；ｎＧ１は２〜４の整数）【選択図】なし
