摘要： Provided is an LED package and a method for manufacturing the same wherein, if its sealing resin containing phosphor particles each having a coating layer is cut or ground, age deterioration of the phosphor particles in the cut or ground surface is prevented. The method includes: mounting LED elements on a substrate; filling a first resin on the substrate to seal the LED elements, the first resin being transparent or translucent and containing wavelength conversion particles configured by forming a coating layer on at least part of the surface of each phosphor particle which converts the wavelength of light emitted from the LED elements; cutting or grinding the first resin; and forming a protective layer with a second resin on a cut surface of the first resin exposed as a result of the cutting or on a ground surface of the first resin, the second resin not containing the wavelength conversion particles.

摘要： A planar light unit is provided that suppresses appearance of a bright line when viewed from the side of the emission surface of the light guide plate. The planar light unit includes a light source, and a light guide plate including an incident surface for receiving light emitted from the light source, an emission surface from which the light introduced through the incident surface is emitted, an opposing surface disposed so as to oppose the emission surface, and a side surface disposed along an outer periphery of the emission surface and the opposing surface. The emission surface has a non-rectangular outer shape, and at least a part of the side surface is formed as a diffusing surface.
