PROBLEM TO BE SOLVED: To provide a light source device achieving high and uniform brightness, suitable for a large display device. SOLUTION: The light source device comprises a resin board and a light source. The resin board includes particles whose turbidity (τ) is in the range from 0.05 to 0.4 when the degree of scattering of incident light by the particles is expressed by the turbidity (τ). A light diffusion part is present on the rear surface of the resin board. At least one end surface of the resin board is a light incident surface, and the front of the resin board is a light emitting surface. |
