    Abstract: The present embodiment comprises: a plurality of light-emitting units; and a reflector including reflector units having spaces formed to receive the plurality of light-emitting units, respectively. Each of the plurality of light-emitting units includes an LED package mounted on a substrate and a light diffusion layer having a groove portion formed on a surface opposite to the substrate in the LED package, wherein the outer circumference of the light diffusion layer faces the inner surface of a reflector unit. In the reflector, the plurality of reflector units are integrally formed, the spaces expand along a direction extending away from the substrate, and a wall forming each of the spaces surrounds the outer circumference of each of the LED package and the light diffusion layer.

    Abstract: Provided is a display apparatus. The display apparatus may include a display panel and a backlight provided adjacent the display panel. The backlight may include an optical sheet provided adjacent the display panel, a reflector provided a prescribed distance from the optical sheet, at least one light emitting device provided adjacent the reflector, and a lens provided over a corresponding the light emitting device. The lens may include a lower recess formed on a bottom surface of the lens and provided a prescribed distance over the light emitting device, and an upper recess formed on a top surface of the lens and provided to vertically overlap the bottom recess. The lower recess may include an upper surface that extends from the side surface and having a prescribed shape and curvature. The upper recess may also include a lower surface having a prescribed shape and curvature.

    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.
