Abstract
A planar light emitting device includes a light-emitting element having a light-transmitting substrate on one side; and a front film in contact with the light-emitting element on the side of the light-transmitting substrate, the front film includes at least three layers including a substrate film and particle-containing resin layers on both surfaces of the substrate film; wherein the resin layer (a first particle-containing layer) on the light incidence side of the front film contains 1 to 50% by weight of the particles and the resin layer (a second particle-containing layer) on the light exiting side of the front film contains 20 to 80% by weight of the particles.
