Abstract
A display device includes a light emitting unit and a display panel including a first color filter. The light emitting unit includes a light source generating a blue light, and a light-converting part converting the blue light into a white light and emitting the white light to an exterior. The first color filter, through which the white light passes, includes a first coloring agent that absorbs about 95% to about 100% of light having wavelength of about 420 nm to about 470 nm in the white light. Thus, a color reproducibility of the display device may be improved.
