Abstract: A backlight unit and an LCD having the same are provided to improve the assemblage deflection related to twist of a reflection plate, which is caused by a human factor while attaching the reflection plate to a lower cover, by using an aligning member which positions the reflection plate below a light guiding plate without twisting the reflection plate. A lower cover(132) includes a lateral face and a bottom face. A lamp housing member(134) has a lamp(130) for emitting light. A light guiding plate is disposed above the bottom face of the lower cover to guide the light emitted from the lamp. A reflection plate is disposed between the bottom face of the lower cover and the light guiding plate to reflect the light emitted from the lamp. An aligning member(138b) is extended from at least one side of the reflection plate and contacted with a lateral face of the light guiding plate. The aligning member aligns the reflection plate and the light guiding plate. A main support(148) is positioned at lateral faces of the lamp housing member and the reflection plate. An LCD panel(150) is formed above the light guiding plate to receive the light emitted from the lamp.
