WHITE LIGHT EMITTING DEVICE, DISPLAY APPARATUS AND ILLUMINATION APPARATUS

摘要

PURPOSE: A white light emitting device, a display using the same, and a lighting device are provided to improve the transmittance of an LCD by reducing the peak intensity of a color mixing region. CONSTITUTION: A blue light emitting diode emits blue light with a peak wavelength between 430 and 460 nm. A first wavelength conversion material is excited by the blue light and emits green light. A second wavelength material is excited by the blue light and emits red light. White light includes a first peak wavelength in a wavelength band between 525 and 545 nm and a second peak wavelength in the wavelength band between 615 and 650 nm. The lowest relative intensity between the first peak wavelength and the second peak wavelength is 0.08 of the relative intensity of the blue light or less.
