PROBLEM TO BE SOLVED: To provide an illumination display device that can uniform the illuminance of an object for appreciation to which light is applied and suppress the amount of light that leaks outside.SOLUTION: By using specular reflection characteristics in order to uniform illuminance, a cabinet 4 generates outside leak light W that is difficult to be invisible to a user. The generation of the outside leak light W causes the user to extremely dazzle during appreciation, which is unfavorable. As a countermeasure against the outside leak, an LED 2 has predetermined beam characteristics, thereby decreasing specular reflection light. As a further countermeasure, the LED 2 has predetermined beam characteristics and a reflection plate 3 is tilted, thereby improving illuminance by the specular reflection characteristics. |
