  • Patent number: 9235997
    Abstract: Provided is an image display panel, image display panel installation equipment, and a manufacturing method for an image display panel, which display an image by using reflective light and realize a high reproducibility of a base image with a simple method. An image is displayed by a plate-like body processed through carving work. The plate-like body has a main portion made of a metal reflecting light and a surface layer portion made of a material absorbing light more than the main portion. The carving work forms linear V-shaped grooves on the front surface side of the plate-like body such that each minute section includes a plurality of grooves. Shading of the image is expressed by the depths of the V-shaped grooves. The image is displayed by light absorption on the surface layer portion and light reflection on the V-shaped grooves.
