PROBLEM TO BE SOLVED: To provide a mold frame and optical sheets for preventing light leakage, and a backlight unit and a liquid crystal display including the same.SOLUTION: A mold frame includes a first guide A defining the position of a photoconversion layer and at least one of optical sheets disposed on the photoconversion layer. The first guide A includes a first surface facing a liquid crystal panel, a second surface opposite to the first surface, and a third surface extended from the edge of the first surface to the edge of second surface. At least a portion of the second surface is provided with a strip, and the strip overlaps a region adjacent to the edge of the top surface of the optical sheet or the top surface of the photoconversion layer.SELECTED DRAWING: Figure 1 【課題】光漏れを防止するためのモールドフレームおよび光学シートと、これを含むバックライトユニットおよび液晶表示装置を提供する。【解決手段】モールドフレームは、光転換層および光転換層上に配置された一つ以上の光学シートの位置を限定する第１ガイドＡを含み、第１ガイドＡは、液晶パネルに向かう第１表面と、第１表面と反対になる第２表面と、第１表面の角部から第２表面の角部に向かって延長された第３表面とを含み、第２表面の少なくとも一部には、ストリップが提供され、ストリップは、光学シートの最上面または光転換層の最上面のエッジに隣接した部分と重なる。【選択図】図１
