Claim 17:
18. A display device comprising:
a liquid crystal panel; and
a light source plate disposed behind at least the liquid crystal panel and configured to provide the liquid crystal panel with light,
wherein the light source plate includes:
a printed circuit board (PCB) comprising a mounting surface;
a light emitting diode (LED) chip;
a transparent resin disposed on at least the LED chip to substantially surround the LED chip;
a light conversion layer configured to convert a wavelength of light emitted from the LED chip, the light conversion layer substantially surrounding an outer surface of the transparent resin;
a barrier layer covering the light conversion layer from an outside; and
an auxiliary light conversion layer at least partially inside the transparent resin and configured to convert a wavelength of light emitted from the LED chip, and
wherein the device is configured so that light reflected from the auxiliary light conversion layer is to pass through the transparent resin and then pass through the light conversion layer.
