1. A backlight assembly comprising:
a waveguide plate guiding light; a first light-emitting module disposed on a first side of the waveguide plate, the first light-emitting module including a plurality of first light-emitting blocks; a second light-emitting module disposed on a second side of the waveguide plate, the second light-emitting module including a plurality of second light-emitting blocks; and a plurality of optical drivers controlling luminance levels of the first light-emitting blocks and the second light-emitting blocks, wherein at least one of the first light-emitting blocks, at least one of the second light-emitting blocks, and at least one of the optical drivers are electrically connected to each other, wherein a first end of the at least one first light-emitting block is electrically connected to the at least one optical driver, a second end of the at least one first light emitting block is connected to a first end of the at least one second light-emitting block, and a second end of the at least one second light-emitting block is electrically connected to the at least one optical driver, wherein the electrical connection between the second end of the at least one first light emitting block and the first end of the at least one second light-emitting block is not through the at least one optical driver and traverses across the waveguide plate, wherein the electrical connection does not pass through a ground, and wherein a voltage provided by the at least one optical driver is supplied to the at least one first light-emitting block through the at least one second light-emitting block.
