Abstract:
A surface-emitting unit includes a surface-emitting panel which emits light, a transmissive member which is arranged to face a light-emitting surface and propagates light emitted from the surface-emitting panel, and a reflection member which scatters propagated light. The light-emitting surface has a light-emitting region and a non-light-emitting region. The reflection member is provided on the surface-emitting panel so as to overlap with the non-light-emitting region. When a light distribution curve in a plane perpendicular to the light-emitting surface is drawn for each surface-emitting panel, the light distribution curve has at least a portion in which a condition of L>cos θ is satisfied, with a luminance on a front side along an axis extending in a direction of normal to the light-emitting surface being defined as 1 and L representing a luminance in a direction in which an angle formed with respect to the axis in the plane is θ.
