摘要： A surface illuminant device includes a surface illuminant having a light distribution characteristic with no directivity relative to specific directions, and a prism sheet having a plurality of prisms each having a predetermined apical angle. The prism sheet is placed on the light emission side of the surface illuminant. One side of the prism sheet on which a plurality of prisms are placed is opposite to the light emission side of the surface illuminant. Accordingly, light can be emitted in a plurality of specific directions in concentrative manner to enhance luminance in that plurality of directions. Further, the surface illuminant device includes an optical sheet which condenses the incident light. In the luminance distribution (light distribution characteristic) thus obtained, the luminance gently decreases in the vicinity of the directions in which light is emitted in concentrative manner.

摘要： In a surface-area light source device, a light entrance side surface of a light guide plate of a surface-area light source device has a staircase shape having steps in the vertical direction, and light emission diodes are provided at each step. The structure enables the distance between a light emission diode provided at one step and light emission diodes provided at an adjacent step to be maintained greater even if the thickness of the light guide plate is reduced so as to decrease intervals of the light emission diodes in the direction of the thickness of the light guide plate. As a consequence, the amount of transmission and reception of heat produced by the light emission diodes is reduced to prevent an increase in the temperature of the diodes. This allows a reduction in the thickness of the light guide plate with the brightness of light emitted from the light guide plate maintained, enabling the surface-area light source device to be thinned. As a result, a large number of light emitting diodes are provided, so that the brightness of the surface light source device is increased.
