A light emitting device comprises: a light guiding plate including two facing principal surfaces and circumferential end surfaces connecting the principal surfaces; and a point-like light source facing at least one surface of the circumferential end surfaces of the light guiding plate. One surface of the circumferential end surfaces except the surface where the light source is arranged is a light emitting surface, the thickness of the light guiding plate facing the light source is smaller than the thickness of a portion constituting the light emitting surface and is smaller than the thickness of a light emitting surface of the light source, a diffusing unit is formed on at least one of the principal surfaces; and a reflection member covering peripheries of the light source and the light guiding plate except portions constituting the light emitting surfaces of the light source and the light guiding plate is provided.
