1. An organic light emitting display device comprising:

  • a substrate having a plurality of sub-pixel areas;

    a switching thin film transistor formed on each of the sub-pixel areas, wherein the switching thin film transistor has a first control electrode, a first input electrode and a first output electrode;

    a driving thin film transistor connected to the switching thin film transistor, wherein the driving thin film transistor has a second control electrode, a second input electrode and a second output electrode;

    a color filter formed on at least one of sub-pixel areas;

    an insulating layer formed on the switching thin film transistor and the driving thin film transistor, wherein the insulating layer has a groove and a contact hole;

    a pixel electrode electrically connected to the driving thin film transistor through the contact hole, the pixel electrode extending to the groove to be partially contained in the groove;

    wherein the pixel electrode has an edge declined in the groove;

    a cover member covering the edge of the pixel electrode;

    wherein the cover member comprises an organic material and a position of an upper surface of the cover member is substantially the same or is lower than a position of an upper surface of the pixel electrode;

    an organic light emitting member formed on the pixel electrode; and

    a common electrode formed on the organic light emitting member.
