摘要
Disclosed are a light guide panel for a TFT-LCD back light unit and a TFT-LCD back light unit and a TFT-LCD device having the same. The light guide panel (30) includes a main light guide member (300) for converting light into uniform plane light and emitting the plane light through an upper surface thereof; and subsidiary light guide member (330), each of which is disposed at the corresponding one of the side surfaces of the main light guide member and is provided with a first surface (331) being close to the corresponding side surface of the main light guide member, a second surface (332) being parallel with the first surface (331), having a height higher than that of the first surface (331), and being close to the corresponding one of light sources (305), and connection surfaces (333, 334) for connecting the first surface (331) and the second surface (332).
