LIGHT EMITTING APPARATUS, BACKLIGHT APPARATUS, AND DISPLAY APPARATUS

摘要

A light emitting apparatus including a first and a second light source, wherein both light sources have spectral characteristics of blue light having an emission light peak within a first wavelength range, at least one of the light sources further has a spectral characteristic of at least one of green light having an emission light peak within a second wavelength range and red light having an emission light peak within a third wavelength range, and a composite spectral characteristic resulting from light emissions from the both light sources has peaks within the first, the second, and the third wavelength ranges, the peak within the first wavelength range has a larger half-value width than others, and the peak within the first wavelength range has a substantially symmetric shape about the peak wavelength.
