A power supply circuit (100) drives an LED array (8) including at least one LED, the LED array being provided to the rear surface of a liquid crystal panel (2), and feeds power to a source driver (6) for driving the liquid crystal panel (2). The source driver (6) and the LED array (8) are vertically stacked such that respective power supply currents thereof flow along the same path. Current drivers (161-16n) are provided on paths of LED strings (81-8n) and generate drive currents (IDRV1-IDRVn). A first power supply circuit (10) feeds power between two ends (P1-P2) of a load circuit (7) formed when the LED array (8), the current driver (16), and the source driver (6) are vertically stacked. A second power supply circuit (20) feeds power between two ends (PVDD-PVSS) of the source driver (6). |
