Abstract
Disclosed is a backlight panel employing a white light emitting diode. The white light emitting diode includes a blue light emitting diode chip and red and green phosphors positioned over the blue light emitting diode chip. Accordingly, since the backlighting can be performed using white light with distinct red, green and blue wavelengths, the color reproducibility can be enhanced. Further, since the white light can be implemented with a single light emitting diode, the manufacturing costs and thickness of the backlight panel can also be reduced.
