摘要： A surface light source includes a light source and an optical waveguide plate. The light source serves to emit light. The optical waveguide plate has an incident end face where the light is incident and a light exit surface where the light incident on the incident end face exits. Further, the optical waveguide plate has a refractive index n. The incident end face has a plurality of concave portions. The angle between a plane formed by the plurality of concave portions and a tangent plane of the incident end face is not more than (90−2·arcsin(1/n)) degree.

摘要： A surface light source includes: a light guiding plate including, in a main region, a light emitting surface and a back surface facing the light emitting surface; and a light source being provided on a back surface side in an end region of the light guiding plate, the light source emitting light so that the light emitted from the light emitting surface. The surface light source further includes: an inclining surface being formed along an end section on the light emitting surface side in the end region so that the light guiding plate becomes thinner toward the end section; a reflecting member covering the inclining surface; and a light incident end face being provided on the back surface side and extending along the end section, the inclining surface being formed so that light entering the light incident end face at a right angle is totally reflected by the light incident end face after being reflected by the inclining surface or the reflecting member. With this arrangement, it is possible to realize a surface light source that is larger in size and thinner in thickness, and a display device having a narrower frame.

摘要： A device includes, but is not limited to, a first transistor, a first current mirror circuit, a second transistor, and a first compensation circuit. The first transistor is controlled by a first control voltage. The first current mirror circuit is driven by the first transistor as a first current source. The second transistor is driven by the first current mirror circuit. The second transistor has a first output voltage that varies depending on the first control voltage. The first compensation circuit reduces variations of the first output voltage. The variations of the first output voltage are caused by variations in performance of the first and second transistors.
