Abstract

A display device is provided, which includes, a substrate, a plurality of gate lines formed on the substrate, a gate driver disposed on the substrate and transmitting gate signals to the gate lines, a repair gate driver disposed on the substrate and having a structure substantially the same as that of the gate driver, and a signal line coupled to the gate driver and the repair gate driver and transmitting at least one control signal to the gate driver.

Claims (14)

1. A display device comprising:

a substrate;

a plurality of gate lines formed on the substrate;

a gate driver disposed on the substrate and configured to transmit gate signals to the gate lines;

a repair gate driver disposed on the substrate and having a substantially similar structure as the gate driver;

a clock signal line having a first portion connected to certain stages of the gate driver, and a second portion connected to corresponding stages of the repair gate driver, the first portion being electrically disconnected from the second portion but configured for electrical connection to the second portion; and

a signal line connecting the gate driver with the repair gate driver, and configured to transmit at least one control signal to the gate driver;

wherein the gate driver and the repair gate driver each respectively comprise a plurality of the stages; and

first and final stages of the repair gate driver and first and final stages of the gate driver are each coupled to the signal line.

2. The device of claim 1 , wherein the gate driver comprises a plurality of stages each configured to output the gate signals based on the control signal.

3. The device of claim 2 , wherein the signal line coupled to at least one of the stages and the control signal comprises a scanning start signal.

4. The device of claim 3 , wherein the gate driver and the repair gate driver are coupled to the gate lines.

5. The device of claim 4 , wherein the gate driver and the repair gate driver are integrated in the substrate.

6. The device of claim 5 , wherein the gate driver and the repair gate driver are positioned at opposite sides of the substrate.
