ORGANIC LIGHT EMITTING DISPLAY DEVICE

The present invention relates to an organic light emitting display device capable of compensating the threshold voltage of a driving transistor which drives an organic light emitting element of each pixel to emit light. According to the present invention, the organic light emitting device includes: a display panel which includes a plurality of gate line groups intersecting each other and defining pixel areas, a plurality of data lines, a plurality of dummy lines parallel to the data lines, and a plurality of pixels formed in the pixel areas to connect one gate line group to a data line and a dummy line; a first and a second row driving unit which are connected to one side and the other side of the gate line groups, respectively; a first column driving unit which is connected to the top of each of the data lines and the dummy lines; and a second column driving unit which is connected to the bottom of each of the data lines and the dummy lines. Each of the dummy lines can be separated into an upper part and a lower part by a separation unit.
