The surface light source device of side light type comprises a light scattering guide 20 having a light incidence surface 22, a light emission surface 23 and an inclined surface 25. The device further includes a primary light source L arranged around one side of the light incidence surface 22, a silver foil R surrounding the primary light source L, a prism sheet 4 arranged along the light emission surface 23, and a silver foil S arranged along the inclined surface 25. The inclined surface 25 of the light scattering guide 20 composed of three sections I, II and III. The section I is a convex cylindrical surface section having a radius of curvature of 330 mm. The tangential direction at the end of the guide on the side of the light incidence surface 22 is parallel to the light emission surface 23. The tangential direction at the boundary between the sections I and II is inclined at an angle 4.degree. with respect to the light emission surface 23. The sections II and III are straight sections whose inclinations are 4.degree. and 3.6.degree. with respect to the light emission surface 23, respectively. The distribution of emitted light intensity from the surface light source device has a higher luminance around its center. Various distributions of emitted light intensity are provided by varying the transition of inclinations of the inclined surface (particularly refer to FIG. 13).

摘要： A surface illuminate device illuminates a liquid crystal display panel by diffused light produced through a diffusing plate disposed on the front of an illuminant section. A prism sheet having many triangular prisms is disposed on the exit side of the diffusing plate so that the longitudinal direction of each prism is nearly parallel to the plane of polarization of a polarizing plate placed on the prism sheet side of the liquid crystal display panel. Thus, the surface illuminant device can provide bright illumination suitable for the backlight of the liquid crystal display panel.

摘要： An effective radiation region of a rod-type light source 8 having circumferences of electrodes 8A and 8B has a length AR. A light diffusible surface 10D (or 10D′) is formed on the rear surface (or emitting surface) of a light guide plate 10 to which a light is supplied from the rod-type light source 8. The light diffusible surface 10D (10D′) has an emission quantity suppressing region AR1, emission quantity promoting region AR2 and light quantity control region AR3. The emission quantity suppressing region AR1 is formed in the vicinity of an incidence surface of the light guide plate 10 so as to have a dimension nearly equal to AR. The emission quantity promoting region AR2 is formed in the vicinities of both the ends of the emission quantity suppressing region AR1. The emission quantity promoting region AR2 is formed so as to have light scattering power which is increased locally near the incidence surface. The light quantity control region AR3 is formed so that light scattering power is increased gradually according to a distance from the incidence surface. The emission quantity suppressing region AR1 prevents excessive light emission, and the emission quantity promoting region AR2 supplements insufficient light emission in the circumferences of the electrodes 8A and 8B.

摘要： A light regulation element regulates both the travelling direction and diffusion state of a light emitted from a surface light source device. Lights from a cylindrical light source 2 such as a cold cathode tube is introduced in a light guide 1. The light guide 1 has an emission surface 1a on the side opposite to a reflection element 4, and a light regulation element 3 is arranged in opposition to the emission surface 1a. Protrusions 3a are formed on one surface or both surfaces of the light regulation element 3. Coated on the surface on the light emission side of the light regulation element 3 is a light diffusion layer 5. The turbidity of the light diffusion layer 5 falls within a range from 1900 cm−1 to 2400 cm−1 . The light emitted from the emission surface 1a of the light guide penetrates the light regulation element 3, thereby causing the light travelling direction to be regulated. Then, the light whose travelling direction has been regulated penetrates the light diffusion layer 5, thereby causing a light diffusion. The light diffusion layer 5 is formed, for example, by mixing fine particles of a glass having a light penetrability or of a synthetic resin such as acryl and silicone, or fine hollow particles of glass, acryl resin or the like, or air bubbles in a coating material having a light penetrability.
