An organic light emitting diode display device having a demultiplexing structure is disclosed. One inventive aspect includes a display panel, a scan driver, a data driver, a plurality of demultiplexers and a timing controller. The timing controller includes first, second and third control signal lines. Each demultiplexer includes first, second and third switching elements, and a branch point formed between the control signal lines and the switching elements. The distance between the switching elements and the display panel is less than the distance between the control signal lines and the display panel.
