Claims

[Scope of utility model registration request]

An illumination device in which a light guide plate made of a light guide plate and a transparent material is laminated and arranged in parallel on the rear surface of a display panel, and the display panel surface is illuminated with light emitted from a light source such as a bulb provided in a partially thick part of the light guide plate. A light scattering structure such as stippling, hair lines, or microbubbles is formed on the front surface, rear surface, or thickness of the light guide plate, and the rear surface of the plate including the recess structure formed at an appropriate part of the light guide plate is connected to the light guide plate. A lighting device characterized by being covered with a reflective sheet in close contact with the lighting device.
