Abstract: Disclosed is a display device. The display device includes a display panel, an optical assembly configured to provide blue-based light to the display panel, and a light-absorbing layer located in the path of light provided from the optical assembly to the display panel, the light-absorbing layer being configured to absorb light in a predetermined wavelength range. The light provided to the display panel through the light-absorbing layer has optical characteristics such that the intensity of green-based light is 20 to 70% of the intensity (100%) of the blue-based light and the intensity of red-based light is 20 to 70% of the intensity of the blue-based light.
