When using a flexible substrate to protect and support various components of an organic light emitting display device, among components including driving elements disposed on each of pixels of the organic light emitting display device, components where a high-level signal is applied during an emission period are grouped and are disposed on one side of the pixels. Further, components where a low-level signal is applied during the emission period are grouped and are disposed on the other side of the pixels. Accordingly, an electric field occurring due to a potential difference in the flexible substrate is minimized and shifting of a threshold voltage Vth of a thin-film transistor may be minimized. Thus, an OLED without an after-image can be provided.
