BACKLIGHT UNIT AND LIQUID CRYSTAL DISPLAY DEVICE |
| 摘要 |
The backlight unit includes two or more light sources, and a wavelength conversion member positioned on each of optical paths of light emitted by the two or more light sources, wherein the wavelength conversion member includes a wavelength conversion layer containing at least a phosphor emitting green light when excited with exciting light and a phosphor emitting red light when excited with exciting light, and at least either maximum emission wavelengths or angles of incidence of entry into the wavelength conversion member of the light emitted by the two or more light sources differ. |
