PURPOSE: A display device is provided to improve a data drive margin by preventing the distortion of a source voltage duet to a noise which is generated at one of a first and a second source voltage. CONSTITUTION: A printed circuit board includes a first voltage wiring(201), and a second voltage wiring(202). The first voltage wiring supplies a first source voltage to a digital processing unit of a data driver. A second voltage wiring supplies a second source voltage to an analog processing unit of a data driver and is electrically separated from the first wiring.
