Abstract: An optical lens, a backlight unit including the optical lens, and a display device including the optical lens are disclosed. The optical lens includes a first surface forming an upper part, a second surface positioned opposite the first surface and forming a lower part, and a third surface connecting the first surface and the second surface. At least a portion of the second surface forms a bottom parallel to the first surface. At least a portion of the second surface is inclined from the bottom toward the third surface.
