摘要：PURPOSE:To obtain a plane light surface which is large on the whole and reduced in thickness and weight, and to control the quantity and wavelength of light according to in-u conditions and increa the angle of the visual field by guiding the light from a light source efficiently to a light projection surface which has many convex surface shapes through a light guide part and a reflecting layer. CONSTITUTION:Even when the thickness of the guide part 2 is made smaller than the diameter of a fluorescent lamp A, the light from the light source is reflected by reflecting surfaces 4 and 8 and the angle of the visual field of a liquid crystal display 5 is incread by the light projection surface 3 which has many lenticular lens shape and fly-eye shapes 11. When the pitch of the shapes 11 is t to 0.01-10mm, the flatness of the light projection surface and light diffusibility to, specially, right and left are improved. A filter 9 is provided at the periphery of the light source to control the intensity and hue of the light. Thus, the light is guided to the light projection surface efficiently to eliminate an irregularity in illuminance and increa the angle of the visual field, and conquently the whole body is sized large and also reduced in thickness and weight and the quantity and wavelength of the light are adjusted freely according to the in-u conditions.
