    • PROBLEM TO BE SOLVED: To provide a display having such a photochromic property as to exhibit two or more colors. SOLUTION: The display comprises an arrangement of a plurality of optically anisotropic rotatable elements, each of the rotatable elements has a surface in contact with an enabling fluid, the rotatable elements are electrically dipolar in the presence of the enabling fluid and thus are subject to rotation upon application of an electric field, the rotatable elements are free to rotate in place but not free to translate substantially so as to disrupt the arrangement of rotatable elements, a first portion of the surface of each of the rotatable elements contains a chelating agent and a spiropyran material of formula (1) or (2), wherein (n) is an integer representing the number of repeat -CH2 - units and R is -H or -CH=CH2 , and a second portion of the surface contains substantially no spiropyran.
    • 要解决的问题:提供具有这样的光致变色性能的显示器,以显示两种或更多种颜色。 解决方案:显示器包括多个光学各向异性可旋转元件的布置,每个可旋转元件具有与启用流体接触的表面,可旋转元件在有效流体存在的情况下是电偶极性的,因此被旋转 在施加电场时,可旋转元件自由旋转就位,但不能自由平移,从而破坏可旋转元件的布置,每个可旋转元件的表面的第一部分包含螯合剂和 式(1)或(2)的吡咯啉材料,其中(n)是表示重复-CH 2 - 单元数的整数,R是-H或-CH = CH 2,表面的第二部分基本上不含螺吡喃 。
