Photorecording element and liquid crystal cell comprising the same
 A photorecording element is disclosed which consists of a transparent substrate, a molecular layer of an organic compound with an ability to change structure reversibly by virtue of light and disposed in direct contact with the transparent substrate, and a layer of liquid crystals disposed in direct contact with the molecular layer. A liquid crystal cell comprising the photorecording element is also disclosed. A modification having fine deformations on the surface of the transparent substrate and a modification having a dichroic dye contained in the layer of liquid crystals are embraced by the present invention.
