Abstract

An organic light emitting display device includes a plurality of data lines, a plurality of scan lines disposed intersecting with the plurality of data lines, and a plurality of sub-pixels each connected to at least one of the plurality of data lines and at least one of the plurality of scan lines. The plurality of sub-pixels includes at least a red sub-pixel, a plurality of green sub-pixels, and a blue sub-pixel. In an embodiment, a green sub-pixel and a blue sub-pixel are connected to a data line and another green sub-pixel and a red sub-pixel are connected to an adjacent data line. Thus, the sub-pixels can be seen as being disposed irregularly, so that an artifact of a displayed image can be reduced.
