摘要： A backlight system (30) includes a light emitting section (31) and an imaging optical system. The imaging optical system includes a first microlens array (MLA1) and a second microlens array (MLA2). The lenses (1A) separates the beams of light emitted from the light emitting section (31) by RGB, and causes them to be converged at a pitch same as a pitch at which the picture elements are arrayed.

摘要： Conventional planar light source devices have a problem that increasing a utilization ratio of light results in a very narrow angle distribution of light. A planar light source device of the present invention has a light source (1), a light guide plate (2) for introducing light coming from the light source via a light-incident plane of the light guide plate and emits the light from almost all area of a light emission plane, and a light source side reflector (3) for reflecting the light coming from the light source and light which comes from the light source and is reflected by the light-incident plane of the light guide plate so that the reflected light is emitted to the light-incident plane of the light guide plate. The planar light source device further includes a lower side reflector (5) for introducing light emitted from the lower plane of the light guide plate into the light guide plate again, and an optical member (4) for changing a traveling direction of first light (10) which is introduced via the light-incident plane to pass through the light guide plate and is emitted from an upper plane of the light guide plate to a vertical upper direction. The lower side reflector is inclined by an angle of 5°-60° with respect to the lower plane of the light guide plate, and θ2=90°−θ1±10° is met where θ1 (°) represents a maximum angle between the upper plane and a direction in which the first light is emitted from the upper plane and θ2 (°) represents an apex angle of the optical member.
