Abstract:
A backlight unit includes a light-guide plate, a light source, and a phosphor sheet including a red phosphor material. The light source includes blue light emitting diodes, and green semiconductor lasers. The red phosphor material is excited by light from the blue light emitting diodes and emits red light. The phosphor sheet is solid and disposed on a surface of a first principal plane of the light-guide plate to define a first mixing light emission surface on the first principal plane of the light-guide plate from which green light emitted from the green semiconductor lasers and blue light from the blue light emitting diodes are emitted toward the phosphor sheet and a second mixing light emission surface on the phosphor sheet from which red light emitted from the red phosphor material, green light emitted from the green semiconductor lasers, and blue light from the blue light emitting diodes are emitted.

Claim (Index 1):
A backlight unit comprising:\n a light-guide plate having a first principal plane, a second principal plane at opposite side of the first principal plane, and at least one edge; a light source optically coupled with the light-guide plate, with which light is input from a plane of the light-guide plate and white-light is output from the first principal plane of the light-guide plate; and a phosphor sheet including a red phosphor material, wherein the light source comprises\n a plurality of blue light emitting diodes, and \n a plurality of green semiconductor lasers having emission peaks at green light wavelengths, \n wherein the red phosphor material is excited by light from the blue light emitting diodes and emits red light, and \n wherein the phosphor sheet is solid and disposed on a surface of the first principal plane of the light-guide plate to define a first mixing light emission surface on the first principal plane of the light-guide plate from which green light emitted from the green semiconductor lasers and blue light from the blue light emitting diodes are emitted toward the phosphor sheet and a second mixing light emission surface on the phosphor sheet from which red light emitted from the red phosphor material, green light emitted from the green semiconductor lasers, and blue light from the blue light emitting diodes are emitted.
