A color hologram display comprising a combined reflection and volume type of single layer or multilayer, wherein a color pattern of plane characters or images and a color three-dimensional subject image are reconstructably recorded while spatially superposed one upon another,
- wherein any shadow of said color pattern of plane characters or images is unrecorded.
A process of fabricating a color hologram display, comprising recording a color three-dimensional subject image and a color pattern of plane characters or images as hologram images by exposing said subject image and said color pattern of plane characters to light and recording the interference pattern thereof in the same photosensitive material.
A hologram plate used to fabricate a color hologram display, wherein a subject hologram plate for forming a color three-dimensional subject image and a character hologram plate for reconstructing a color pattern image of plane characters or images are separately made, said subject hologram plate and said character hologram plate are positioned with a given space located therebetween, and diffracted light from said subject hologram plate and said character hologram plate is simultaneously entered in the same photosensitive material to record said color three-dimensional subject image and said color pattern image of plane characters or images as hologram images.
