  • Publication number: 20200012037
    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.
