A liquid-crystal or mesomorphic material containing the 2,2'-azoimidazole compounds and electrooptical device comprised of such mesomorphic material are disclosed. The electrooptical devices are useful for systems of electronic representation and processing of information. The compounds therein have two spectrally spaced absorption bands in the visible part of their spectrum such that their position insures the contrast required for the human eye to be able to readily recognize the difference in color. |
