The present invention provides a photosensitive material for use in electrophotography which is prepared by forming a barrier layer containing a peptide polymer between a conductive support and a photosensitive layer. This photosensitive material impedes unnecessary charge infiltration through the conductive support, maintains an appropriate charge acceptability, imparts an adhesive property of the photosensitive layer in relation to the support or flexibility of the photosensitive material, and prevents deterioration of such characteristics as photosensitivity, residual potential, etc. When some acceptor or donor is additionally mixed in said barrier layer, the electrification property thereof is improved.
摘要:
A liquid crystal color display device for displaying a color image represented by an applied image signal, including a liquid crystal cell, one or two polarizers, and a fluorescent light-emitting means. The liquid crystal cell and one polarizer disposed on one side thereof, or the liquid crystal cell and the two polarizers sandwiching the same, jointly constitute a switching element responsive to the image signal applied to the liquid crystal cell for passing electromagnetic radiation in a pattern representing the image given by the image signal. The fluorescent light-emitting means has a fluorescent layer and a lamp for generating electromagnetic radition, and may additionally include a color filter. The fluorescent layer is responsive to the electromagnetic radiation from the lamp for emitting chromatic fluorescent light. Where the fluorescent light-emitting means has the color filter, the fluorescent light passes through the color filter to display the image.
