    Abstract: A backlight unit including a frame having a bottom area and a sidewall area extended from the bottom area; a single substrate located in on the bottom area of the frame, a plurality of optical assemblies being mounted on the single substrate; a reflection sheet located the frame and configured to reflect light emitted by the optical assemblies; and an optical sheet located over the reflection sheet. Further, the reflection sheet a first sheet area corresponding to the bottom area of the frame; a second sheet area corresponding to the sidewall area of the frame; and a cut portion cut from the first sheet at one portion abutting on one side of the single substrate.

    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.
