    Abstract: An optical lens and a display device including the same are provided. An optical lens includes a first surface having a circular cross-sectional shape, a second surface opposite to the first surface, and a third surface configured to connect the first surface and the second surface. The third surface includes a straight surface extending from a boundary of the first surface and a first curved surface extending from the straight surface to the second surface. The straight surface and the first curved surface extending in a path between the first surface and the second surface. The second surface includes a concave recess recessing in a direction of the first surface and the concave recess includes a second curved surface. Light that has passed through the second concave surface changes a path as the light passes through the first curved surface such that light path can be effectively controlled.

    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.
