    Abstract: IMPROVED VISUAL IMAGE DISPLAY DEVICE A visual image display device with improved resolution contains a pair of conductive electrodes in spaced relationship. Adjacent one electrode is a first barrier layer which is typically a resin such as polyamide containing a readily oxidizable and reducible material such as zinc nitrate. Adjacent the other electrode is a thin film of solvent, for example, 1, 2-dichloroethane. Positioned between the film of solvent and the first barrier layer is a second barrier layer which is a normally light transmitting recording medium. The second barrier layer is both photoionizable and capable of electrochemically producing a colored species. Typically the second barrier layer is a solid containing a resin such as polyvinyl butyral, an active material such as l-p-anisyl-3 diethylamino styryl-5-diethylaminophenyl-2-pyrazoline and, in selected embodiments, an activator such as carbon tetrachloride.

    Abstract: An image is formed by exposing to a light pattern a plate comprising a substrate and only a single layer of a photoconductive, non-polymeric, film forming, pyrazoline, oxadiazoles or fluorenone organic compound which has a glass transition temperature below 200 DEG C. and which has both a crystalline phase and an amorphous phase, and developing the plate by causing a selective change in phase between the light exposed and non-exposed areas.
