ABSTRACT:
A backlight apparatus (and light guide and liquid crystal display apparatus incorporating the same) includes a wedge-type light guide having a refractive index n1,and having a top surface, a bottom surface and a side surface, a light source for directing light to the side surface of the wedge-type light guide, a first light transmission layer having a refractive index n2,which is smaller than said refractive index n1,and having a top surface and a bottom surface, wherein the top surface of the first light transmission layer is attached to the bottom surface of the wedge-type light guide, and a light deflecting layer having a top surface attached to the bottom surface of the first light transmission layer for deflecting the incident light from the first light transmission layer toward the top surface of the wedge-type light guide.
