摘要： This edge light-type backlight device comprises a light guide plate, a light source disposed at one end part of the light guide plate, a light diffusion sheet and a prism sheet on a light emission face of the light guide plate. The refractive index of the prism sheet exceeds 1.60, a peak of emitted light distribution of a light emission face of the light diffusion sheet in a plane orthogonal to a direction along the one end part of the light guide plate is within an angle range of 48°-58° with respect to a normal direction of the light emission face, and the emitted light of the light emission face of the light diffusion sheet diminishes toward −90° or 90° with respect to the normal line from the angle range of the peak of the emitted light distribution. High frontal brightness and diffusion are realized.

The refractive index of the prism sheet exceeds 1.60, a peak of emitted light distribution of the light emission face in a plane parallel to the one end part of the light guide plate and orthogonal to the light emission face is within an angle ranges of 30°˜45° and −30°˜−45° with respect to a normal direction of the light emission face. The emitted light of the light emission face diminishes toward an emission angle −90° or 90° with respect to the normal line from the angle ranges of the peak of the emitted light distribution. High frontal brightness and diffusion are realized.
