<p>A durability-enhanced optical sheet and an edge-type backlight unit having the optical sheet. The edge-type backlight unit includes a light source unit that includes a plurality of light sources, a light guide unit that is disposed adjacently to the light source unit and controls a path of light generated from the light source unit, a diffusion sheet disposed on the light guide plate, and an optical sheet that is disposed on the diffusion sheet and includes a lens unit and a non-lens unit, wherein the non-lens unit includes a first base unit, a second base unit, and a bonding layer for bonding the first and second base units. The optical sheet includes two base unit layers, and thus, sheet waves that can be caused due to heat can be prevented, modulus can be increased, and durability of the optical sheet can be enhanced.</p> |
