ABSTRACT:
A planar light-emitting device has a plurality of light-emitting units each having a lightguide plate having an upper surface as a light-exiting surface, a lower surface opposite to the light-exiting surface, a peripheral side surface extending between the respective peripheral edges of the upper surface and the lower surface, and a light entrance surface defined by a part of the peripheral side surface. Each light-emitting unit further has a light-emitting set adjacent to the light entrance surface to emit light into the lightguide plate through the light entrance surface, and a support member that fixedly supports the light source and the lightguide plate. The light-emitting units are arranged side by side so that the light-exiting or upper surfaces of their respective lightguide plates are substantially flush with each other.
