4. The organic light emitting display device of claim 2 ,

wherein the second stage initiation signal is activated when an image is displayed on a portion of the entire display area.

5. The organic light emitting display device of claim 4 ,

wherein the gate driver is configured to provide a light emission control signal for determining whether or not to emit light to the plurality of pixels.

6. The organic light emitting display device of claim 5 ,

wherein the gate driver is configured to provide the light emission control signal having a voltage value of an ON level to the pixels disposed in a part of the display area on which an image is displayed.

7. The organic light emitting display device of claim 1 ,

wherein each of the stages is configured to control whether or not a sequential initiation signal activating the other successively disposed stages is provided.

8. The organic light emitting display device of claim 7 ,

wherein each of the stages is configured to provide the sequential initiation signal when the other successively disposed stages are not directly connected with the second stage initiation line.

9. The organic light emitting display device of claim 1 , wherein the first stage initiation signal and the second stage initiation signal are selectively activated.

10. The organic light emitting display device of claim 1 ,

wherein any one of the at least two stage groups directly connected with the second stage initiation line is the stage group which is directly connected with the first stage initiation line.

11. An organic light emitting display device, comprising:

a display panel comprising a plurality of pixels;

a gate driver comprising a plurality of stage groups, each of the stage groups comprising at least one stage configured to provide a gate signal to the pixels;

a timing controller configured to provide any one of first to third stage initiation signals to the at least one stage and configured to provide a first clock signal or a second clock signal to the at least one stage;

first to third stage initiation lines configured to transmit the first to third stage initiation signals respectively, from the timing controller to the gate driver; and

a first clock signal line and a second clock signal line configured to transmit the first clock signal and the second clock signal respectively, from the timing controller to the gate driver,

wherein:

the first stage initiation line is directly connected with one of the stage groups and is not directly connected with the other stage groups; and

the second and third stage initiation line is directly connected with at least two of the stage groups.

12. The organic light emitting display device of claim 11 , wherein the display panel includes a display area on which an image is displayed by the pixels.

13. The organic light emitting display device of claim 12 , wherein the second stage initiation signal or the third stage initiation signal is activated when an image is displayed on a part of the display area.

14. The organic light emitting display device of claim 12 , wherein:

the first stage initiation line is directly connected with the one stage group;

the second stage initiation line is directly connected with the at least two stage groups; and

the third stage initiation line is directly connected with at least one of the stage groups not directly connected with the second stage initiation line.

15. The organic light emitting display device of claim 14 ,

wherein the second stage initiation signal and the third stage initiation signal are activated at least one time in one frame.

16. The organic light emitting display device of claim 14 ,

wherein:

the gate driver is configured to provide a light emission control signal for determining whether or not to emit light to the plurality of pixels; and

the light emission control signal is provided to the pixels disposed in a part of the display area activated by the third stage initiation signal.

17. The organic light emitting display device of claim 16 , wherein the pixels disposed in a part of the display area activated by the third stage initiation signal receive a predetermined data voltage.
