Planar light source and display device using the same

摘要

A planar light source (10) has a solid light-emitting element (1) which emits light by electric energy and an anisotropic scattering color conversion layer (2) formed on the light-emitting side of the solid light-emitting element (1) with substantially no air layer interposed therebetween. The anisotropic scattering color conversion layer (2) has a light-transmitting resin (21), a microregion (22) dispersedly distributed in the light-transmitting resin (21) having birefringence different from that of the light-transmitting resin and at least one light-emitting material (23) incorporated in the light-transmitting resin (21) and/or microregion (22) and the at least one light-transmitting material (23) absorbs light emitted by the solid light-emitting element as excitation light to emit fluorescence or phosphorescence.
