Abstract
An LCD has a drive power supply structure simplified to simplify manufacturing processes of LCDs and to reduce manufacturing costs thereof. The LCD includes a liquid crystal panel, a drive unit, a controller, a backlight drive unit, and a drive voltage generator. The liquid crystal panel includes image display regions. The drive unit drives gate and data lines in the panel. The controller controls the drive unit using image data and synchronization signals from outside. The drive voltage generator is provided on a system or at least one source printed circuit board on which at least one of the drive unit or the controller is formed and converts a voltage level of a drive power provided from outside to generate drive powers of different voltage levels and provides the drive powers to the drive unit, the controller, and the backlight drive unit.
