Abstract: The present disclosure relates to an organic light emitting display device which comprises a plurality of sub-pixels each of which comprises an OLED, a driving TFT, a first TFT for applying a data voltage to a gate electrode of the driving TFT, a second TFT for applying a reference voltage to a source electrode of the driving TFT, and a storage capacitor, a data driver for outputting the data voltage to a data line and the reference voltage to a reference line, and a gate driving unit for outputting signals to a first gate line connected to the gate electrode of the first TFT and a second gate line connected to the gate electrode of the second TFT, wherein two adjacent sub-pixels emitting a same color is supplied with the data voltages through different data lines and share the first gate line and the second gate line.

Abstract: A display device includes a substrate which includes a display area and a non-display area adjacent to the display area, a first planarization layer which is at least partially disposed in the display area, a second planarization layer which is disposed in the non-display area and is spaced apart from the first planarization layer, a contact unit disposed between the first planarization layer and the second planarization layer in the non-display area, and a cathode which extends from the display area to the non-display area to be electrically connected to the contact unit. Accordingly, the first planarization layer and the second planarization layer are spaced apart from each other so that a path through which moisture permeates into the display area through the second planarization layer may be blocked.
