Abstract

A display device includes pixels, each including a switching element; a shift register comprising stages coupled with the switching elements and sequentially generating output signals; clock signal lines transmitting clock signals; at least a control signal line transmitting a control signal; and terminal lines connecting the clock signal lines and the control signal with the stages, wherein the terminal lines comprise at least one common terminal line commonly connected with at least two stages.

Claims (40)

1. A display device comprising:

a first pixel comprising at least one switching element;

a second pixel comprising at least one switching element;

at least one gate driver comprising a pair of stages, wherein the pair of stages comprises at least two stages adjacent to each other and electrically connected to the first pixel and the second pixel, respectively;

a clock signal line configured to transmit a clock signal for controlling a gate signal;

at least one gate-off voltage line configured to transmit a gate-off voltage for providing the gate-off voltage to the pair of stages; and

a terminal line comprising at least one common terminal line for connecting the clock signal line or the gate-off voltage line with each stage of the pair of stages,

wherein a portion of the common terminal line is disposed within the pair of stages.

2. The display device of claim 1 ,

wherein the each stage of the pair of stages comprises a plurality of transistors connected to the common terminal line.

3. The display device of claim 2 ,

wherein the plurality of transistors of one stage of the pair of stages and the plurality of transistors of the other stage of the pair of stages are symmetrically disposed with respect to the common terminal line.

4. The display device of claim 3 ,

wherein the plurality of transistors are disposed adjacent to the common terminal line.

5. The display device of claim 2 ,

wherein the plurality of transistors are disposed adjacent to the common terminal line.

6. The display device of claim 2 ,

wherein one of the clock signal line and the at least one gate-off voltage line is located farthest from the pair of stages from among the clock signal lines and the at least one gate-off voltage line.

7. The display device of claim 6 ,

wherein the plurality of transistors of one stage of the pair of stages and the plurality of transistors of the other stage of the pair of stages are symmetrically disposed with respect to the common terminal line.

8. The display device of claim 7 ,

wherein the plurality of transistors are disposed adjacent to the common terminal line.

9. The display device of claim 6 ,

wherein the plurality of transistors are disposed adjacent to the common terminal line.

10. The display device of claim 6 ,

wherein the clock signal line comprises a first clock signal line and a second clock signal line, wherein each of the first clock signal line and the second clock signal line is connected to at least one stage of the pair of stages.

11. The display device of claim 2 ,

wherein the clock signal line comprises a first clock signal line and a second clock signal line, wherein each of the first clock signal line and the second clock signal line is connected to at least one stage of the pair of stages.

12. The display device of claim 1 ,

wherein one of the clock signal line and the at least one gate-off voltage line is located farthest from the pair of stages from among the clock signal lines and the at least one gate-off voltage line.

13. The display device of claim 12 ,

wherein the clock signal line comprises a first clock signal line and a second clock signal line, wherein each of the first clock signal line and the second clock signal line is connected to at least one stage of the pair of stages.

14. The display device of claim 1 ,

wherein the clock signal line comprises a first clock signal line and a second clock signal line, wherein each of the first clock signal line and the second clock signal line is connected to at least one stage of the pair of stages.

15. The display device of claim 1 ,

wherein the display device further comprises an initializing signal line configured to transmit an initializing signal to the pair of stages.

16. The display device of claim 2 ,

wherein one from among the clock signal line and each of the at least one gate-off voltage lines is located farther from the pair of stages than any other one of the clock signal line and each of the at least one gate-off voltage lines.

17. The display device of claim 1 ,

wherein one from among the clock signal line and each of the at least one gate-off voltage lines is located farther from the pair of stages than any other one of the clock signal line and each of the at least one gate-off voltage lines.
