Abstract: A color display panel comprising a plurality of picture elements arranged in a plurality of rows and a plurality of columns, and a plurality of driving lines disposed substantially along columns of picture elements, each picture element forming a color picture element selected from red picture elements, green picture elements and blue picture elements. Two or three types of color picture elements selected from the red, green and blue picture elements are arranged in a column, and each type of color picture elements among the two or three types of color picture elements arranged in a column are commonly connected to a driving line.

Abstract: A color filter with a good heat resistance is provided on a base plate for a liquid crystal device by vapor deposition of a colorant. Transparent electrodes are formed on the color filter and the thus formed base plate is combined with the other base plate having thereon a TFT circuit for driving a liquid crystal interposed between the base plates. Thus a liquid crystal color display device having a structure suited for driving is provided.

Abstract: A hologram is produced by forming an interference pattern in a recording carrier composed of a polysaccharide made active to radiation in the presence of a compound containing a metal ion.

Abstract: Holograms are produced by exposing a film-like sensitive member composed of polyvinylcarbazole or its derivatives containing an iodine compound to an interference pattern of laser, swelling the sensitive member thus exposed in a first solvent and simultaneously eluting most of the iodine compound, if desired, the iodine compound may be eluted before this swelling treatment, and then shrinking the swollen sensitive member in a second solvent.
