Abstract
PURPOSE: To execute uniform face illumination having a high light flux application rate from. a light source by providing the illumi-nator with a light transmitter formed by plural transparent plate-like body, a light source, a light reflector arranged on the light projection side of the light transmitter so as to have an inclination angle from the transparent plate-like bodies and a plate-like body capable of converting reflected light into diffused light and brought into facially contact with the transmitter. CONSTITUTION: Incident light A from a long light source 101-1 such as a fluorescent lamp to the incident face of the light transmitter 102-1 goes forward in transparent plate-like bodies 108 while repeating total reflection in the inside without being leaked to the outside. After going out from a light projection face, the light A is reflected upward by a light reflector 103-3, reached to a diffusion plate 104-1 through a transparent or translucent body 104-2 and the light illuminates a liquid crystal panel 106 from its rear side as diffused light. Since a light scatter 104 is brought into contact with the face of the light transmitters 102-1, 102-2 and adhesively fixed, the light scatter 104 is not oscillated even at the time of receiving a drop impact and excess impact acceleration is not applied to the panel 106. Consequently face illumination with extremely uniform brightness can be attained.
