Abstract: In a stereoscopic image conversion panel and a stereoscopic image display apparatus, the stereoscopic display panel includes a first lens substrate, a second lens substrate, a stereoscopic image lens part and a lens liquid crystal layer. The stereoscopic image lens part is disposed between the first and second substrates, and includes a main lens and sub-lenses with a concave shape. At least one sub-lens is disposed at opposite edge portions of the main lens. The lens liquid crystal layer is received by the main lens and the sub-lenses, is disposed between the first and second lens substrates, and includes liquid crystal molecules having an anisotropic refractive index. The lens liquid crystal layer refracts a polarized light at an interface between the lens liquid crystal layer and the stereoscopic lens part, to convert a flat image into a stereoscopic image. Therefore, the thickness of the stereoscopic image panel can be reduced.
