ABSTRACT:
A light source device which is uniform in the intensity of distribution of an emitted light and high in the optical utilization efficiency, a display device which is high in recognability and is energy-saving, and an information terminal are provided. A reflecting portion is formed on a surface opposed to an emitting surface of a linear light guide. The reflecting portion is periodically formed with a total reflecting surface guiding a light incident on a linear light guide from a point light source, a light extracting surface allowing the light to reflect in such a way as to emit the light guiding the linear light guide from the emitting surface, and a re-incidence plane which takes the light transmitted but not reflected on the light extracting surface into the linear light guide again. By changing the size of the light extracting surface and the re-incidence plane, the intensity of distribution of the emitting light from the linear light guide can be made uniform.
