Abstract: A display device includes a display panel. A light source is configured to output light having a first color. A light guide plate is disposed below the display panel and includes an incident surface into which the first color light is incident, an opposite surface that is opposite to the incident surface, and an emission surface facing the display panel. A color convertor is disposed between the display panel and the light guide plate. The color convertor is configured to absorb the first color light and to output light having a different color to the display panel. A reflector is disposed below the light guide plate. A first reflection area and an adjacent second reflection area are defined on the reflector. A light absorber is disposed on the first reflection area adjacent to the light source. The light absorber is configured to absorb the first color light.

Abstract: 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.
