Abstract
A backlight assembly includes a plurality of lamps, a first reflecting plate and an optical member. The lamps are disposed substantially parallel with each other and generate light. The bottom reflecting plate is disposed under the lamps to reflect the light. The first reflecting plate is disposed over the lamps to transmit and reflect the light and has a plurality of penetration holes for transmitting the light. The optical member is disposed over the first reflecting plate. The formation density of the penetration holes increases as a position of the penetration holes approaches an intermediate region between adjacent lamps from a region corresponding to a position of the lamps.
