HIGH-CONTRAST BISTABLE SCATTERING LIQUID CRYSTAL LIGHT BULB

PROBLEM TO BE SOLVED: To provide a high-contrast bistable scattering liquid crystal light bulb.SOLUTION: A high-contrast bistable scattering liquid crystal light bulb of the present invention comprises: two substrates; two transparent electrode layers that are respectively provided between the two substrates and respectively laminated on the substrates; an intermediate layer that is provided sandwiched between the two electrode layers, the intermediate layer including a plurality of gaps and a plurality of azobenzene cholesteric liquid crystals where nematic liquid crystals and azobenzene chiral molecules are doped and mixed with each other; and two vertical alignment films that are respectively applied between the electrode layers and the intermediate layer. The azobenzene cholesteric liquid crystals can be added to inject application voltages having different frequencies from the two electrode layers before changing the transmittance of the azobenzene cholesteric liquid crystals, and the application voltages can be removed before stably maintaining a scattered state or a transmitted state to significantly reduce energy consumption.SELECTED DRAWING: Figure 1 【課題】高コントラスト双安定散乱型液晶ライトバルブを提供する。【解決手段】本発明の高コントラスト双安定散乱型液晶ライトバルブは、２つの基板と、それぞれ該２つの基板の間に設けられ、それぞれ各該基板に貼合される２つの透明の電極層と、 中間層であり、該２つの電極層の間に挟み設けられ、該中間層は、複数のギャップと、ネマティック液晶及びアゾベンゼンキラル分子が相互にドープ混合された複数のアゾベンゼンコレステリック液晶と、を含む中間層と、それぞれ各電極層及び中間層の間に塗布される２つの垂直配向膜と、を含み、そのうち、該アゾベンゼンコレステリック液晶の添加によって、異なる周波数の高さの印加電圧を該２つの電極層から注入後に該アゾベンゾコレステリック液晶の透過度を変化させ、且つ該印加電圧を除去した後に散乱状態又は透過状態を安定して維持し、エネルギーの消耗を大幅に減少することができる。【選択図】図１
