Abstract
The present invention provides a color mixing lens which can improve color reproducibility, be made slim and adjust an emission pattern; and a liquid crystal display device having the same. The color mixing lens includes a light receiving portion having light receiving recesses which respectively house light emission diodes formed at a side surface thereof for positioning at least two light emission diodes at the side surface for producing color lights different from each other, a color mixing portion formed on the light receiving portion for mixing the lights from the light emission diodes into a white color light, and a light emission portion formed on the color mixing portion for emitting the white light from the color mixing portion through a top surface thereof.
