Abstract
A laser-addressed liquid crystal cell is disclosed for recording image information in the form of a plurality of marks selectively positioned in accordance with a predefined pattern of pixels. The cell includes a layer of a liquid crystal material, and an infrared radiation absorbing material for producing heat in response to infrared radiation to create the marks by forming scattering regions in the liquid crystal material. A mark positioning layer is included, having infrared transmissive material and infrared non-transmissive material. These material are arranged within the mark positioning layer such that one of these two materials defines a series of discrete elements corresponding to the pattern of pixels. Such material is surrounded within the positioning layer by the other of the two materials.
