Abstract

A holographic image display device according to one embodiment includes: an image display unit on which a holographic image is displayed; and a sense of space providing unit that forms a space surrounding the holographic image, and the sense of space providing unit includes a transparent colored material such that the space It appears colored and the holographic image is recognizable from the outside.

Description

Technical field [0001] The present disclosure relates to a holographic image display device. The present invention requires the priority of Korean Patent Application No. 10-2017-0136878, filed on October 20, 2017, and its full content is incorporated herein by reference. Background technique [0002] The hologram is a record of light (e.g., laser) interference patterns on recording medium (eg, film or photosensitive dry plate). The hologram provides a stereoscopic image of an object. For example, the hologram of the person's head provides a different image according to the viewing position. That is, in one position, I see the left side of the person's head, and see the front side of the person's head at another position, and see the right side of the person's head in yet another position. [0003] In addition, the pseudo hologram refers to a technique that has entered the effect of a hologram, but it is not a hologram. In the pseudo-pendant, a semi-reflective mirror film or trans...
