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.
Claims7
A display device comprising:
- a display panel;
- an optical assembly providing blue-based light to the display panel;
- and
- a light-absorbing layer located in a path of light provided from the optical assembly to the display panel, the light-absorbing layer absorbing light in a predetermined wavelength range, and the light-absorbing layer includes a first light-absorbing layer located between the optical assembly and the display panel and a second light-absorbing layer located between the first light-absorbing layer and the display panel,
- wherein the first light-absorbing layer includes a green phosphor and the second light-absorbing layer includes a red phosphor,
- wherein a thickness of the first light-absorbing layer is at least 10 times thicker than a thickness of the second light-absorbing layer, and the first light-absorbing layer is adhered to the second light-absorbing layer, and
- wherein light provided to the display panel through the light-absorbing layer has optical characteristics such that an intensity of green-based light is 20 to 70% of an intensity (100%) of the blue-based light and an intensity of red-based light is 20 to 70% of the intensity of the blue-based light.
