摘要： A display device includes a backlight assembly including a light emitting unit to emit a light and a display panel receiving the light and displaying an image. The light emitting unit includes a light emitting diode package, an optical lens, and a reflective layer. The light emitting diode package includes at least two light emitting diodes to emit lights having different colors. The optical lens covers the light emitting diode package and includes a first lens surface and a second lens surface changing an optical path of the light incident through the first lens surface. The reflective layer is partially disposed on the first lens surface.
