BACKLIGHT DEVICE AND LIQUID CRYSTAL DISPLAY APPARATUS

摘要

A backlight device (100) includes a first light source (20a, 20b) and a second light source (10) . The first light source (20a, 20b) emits a first light ray (22a, 22b) which is a red laser light ray. The second light source (10) emits a second light ray (13) which is a cyan light ray in a complementary relationship with the laser light ray. The second light source (10) includes a light emitting diode for emitting a blue light ray and a fluorescent substance for absorbing the blue light ray to emit a green light ray.
