Patent ID: 7705931

Claim:
A planar light-emitting device comprising: a lightguide plate having an upper surface as a light exit surface, a lower surface opposite to the upper surface, and a peripheral edge surface between respective peripheral edges of the upper surface and the lower surface, and a part of the peripheral edge being disposed as a light entrance surface; at least one light-emitting package including a substrate having a mount surface, at least one light-emitting element mounted on the mount surface of the substrate, and a light-transmitting resin provided on the mount surface to seal the light-emitting element, the light-transmitting resin having a rear surface contacting the mount surface and a flat front surface opposite to the rear surface and abutting on the light entrance surface of the lightguide plate; and a reflecting sheet disposed to face at least one of the upper surface and lower surface of the lightguide plate, the reflecting sheet extending beyond the light entrance surface and having a reflecting surface facing both the lightguide plate and the light-transmitting resin.
