摘要:
The invention relates to a liquid crystal display device which enables a visual field range to be made wide and luminance drops to be reduced, so that bright displayed images can be presented, and provides a liquid crystal display device comprising, in order from a side of backlight 11, backlight 11, scatter plate 12, and liquid crystal element 20, wherein a transmission type of hologram scatter plate 13 is located in front of a display surface of liquid crystal display element 20. Hologram scatter plate 13, because of having been fabricated by means of single-step or two-step exposure, enables light more or less scattered through scatter plate 12 to be limitedly scattered within a given wide visual field range, so that bright displayed images can be presented over a wide visual field range yet with a reduced luminance drop. Scatter plate 12 may be omitted.

摘要:
A multilayered volume hologram structure of the invention comprises a substrate 2 for a certificate or the like, and an adhesive layer 5, a volume hologram layer 5 and a surface protective film 7 laminated on the substrate in the described order. When a multilayer structure consisting of the volume hologram layer 5 and surface protective layer 5 is forcibly released from the substrate for the purpose of making a photograph replacement or falsifying a personal information area, the volume hologram image can break down certainly, thereby ensuring prevention of falsification. A multilayered volume hologram structure-making label is useful for making a multilayered volume hologram structure.
摘要:
The invention provides a hologram-recording subject plate comprising a block and a variety of subjects fixedly contained therein, which ensures easy, stable yet continuous recording of a multiplicity of identical holograms or different holograms reconstructible by illuminating light as is the case with a hologram-replicating method, a hologram-making method using the same, and a hologram-recorded article. The subject plate comprises a transparent solid block 5 and a hologram-recording subject S contained therein. A photosensitive material film 1 is applied directly onto one surface of the subject plate, and the subject plate is then irradiated with laser light 7 through the photosensitive material film 1. Such simple operation enables a multiplicity of identical holograms to be recorded in an easy, stable yet continuous manner.
