Surface-emitting unit having dimming regions

A surface-emitting unit comprising:

• a plurality of surface-emitting panels which are disposed such that light-emitting surfaces are two-dimensionally aligned and emit light toward a front side;
• a transmissive member which is arranged to face the light-emitting surfaces of adjacent surface-emitting panels, propagates light emitted from the surface-emitting panels as being reflected in the transmissive member, and can allow light to exit from a light exit surface;
• and
• a scattering member which is provided to face the light exit surface of the transmissive member and scatters the light emitted from the plurality of surface-emitting panels,
• the transmissive member having a dimming surface provided between a light incident surface on which light emitted from the surface-emitting panels is incident and the light exit surface,
• the light-emitting surface of each of the plurality of surface-emitting panels having a light-emitting region which emits light and a non-light-emitting region which is located around an outer periphery of the light-emitting region and does not emit light, and
• the dimming surface being configured such that a region facing the non-light-emitting region is different in transmittance of light from a region facing the light-emitting region so as to lessen non-uniformity in a front luminance distribution of the light-emitting surfaces generated by a distribution of light emitted from each of the plurality of surface-emitting panels.
