Abstract:
A liquid crystal display and a light source apparatus capable of improving color reproduction compared to related arts without declining intensity. A light source apparatus includes: a cold cathode fluorescent tube including a B phosphor for blue and a G phosphor for green; and a light emitting diode for red, wherein the G phosphor emits a single-spectrum light with a peak wavelength of 510 to 530 nm, and the light emitting diode emits a single-spectrum light with a peak wavelength of 620 to 650 nm.
