PURPOSE: An organic light emitting display device and a power supply therefor are provided to reduce manufacturing costs by using one power source for an EL(Electroluminescence). CONSTITUTION: A display unit includes a plurality of pixels. A power supply unit(500) includes an output terminal, a reference terminal, and a bias circuit and generates a first power voltage by receiving an input voltage. A first power voltage and a second power voltage are voltages for driving a plurality of pixels. A bias circuit(520) supplies the second power voltage to the reference terminal and the plurality of pixels based on a ground. A current flows from the pixels to the reference terminal. |
