According to the present invention, provided are a data driving unit and a display device using the same. The display device comprises: a digital to analog conversion unit configured to convert a digital signal into either a positive polarity analog signal or a negative polarity analog signal; and an output circuit unit configured to output either the positive polarity analog signal or the negative polarity analog signal, as an output signal, to a transistor which supplies a current to an organic light emitting diode (OLED). Therefore, the display device can delay deterioration of the transistor. |
