Abstract
An illuminating display device for limiting the travel direction of beams. This device includes a main body which is transparent; a display layer disposed on the surface of the main body and including a display mark composed of a cut-out section; a reflective layer formed in the cut-out section on the surface of the main body and having a pattern including light beams reflecting parts and light beams transmitting parts respectively scattered thereover; and a light source disposed in the main body. In this construction, the main body includes a refracting medium, disposed in a passage for light beams emitted from the light source, for regulating the direction of beams which travel outside the device by refracting the beams.

An illuminating display device comprising:
- a main body which is transparent;
- a display layer disposed in surface contact with said main body and including a display mark including a cut-out section and a reflective layer formed, in said cut-out section, on a front surface of said main body, said reflective layer having a pattern including light beam reflecting parts and light beam transmitting parts, respectively scattered thereover, a thin metal layer being formed between and in surface contact with both said main body and a rear surface of the light beam reflecting parts of said reflective layer;
- and
- a light source disposed in said main body, wherein
- said main body includes a refracting medium disposed in a passage for light beams emitted from said light source, for regulating the travel direction of the beams which are incident thereon by refracting the beams and wherein said thin metal layer completely reflects light beams directed at the rear surface of the light beam reflecting parts of said reflective layer.
