Planar light source and display device using the same

摘要

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