Abstract

A display device includes a display panel having a curved side or a polygonal side, the display panel including a plurality of pixels in a display region, a gate driver including a plurality of normal stages connected to each other for outputting gate signals to the pixels via a plurality of gate lines, and a plurality of dummy stages between some of the normal stages, and a data driver providing data signals to the pixels via a plurality of data lines.

Claims (16)

1. A display device comprising:

a plurality of pixels in a display region to display an image;

a plurality of gate lines;

a plurality of data lines crossing the gate lines; and

a gate driver in a non-display region adjacent to the display region, wherein at least a portion of the non-display region has a curved shape in a plan view,

wherein the gate driver comprises:

a plurality of normal gate drivers each having an output terminal that is electrically connected to a corresponding one of the gate lines; and

a plurality of dummy gate drivers each having an output terminal that is electrically floated in a fixed configuration, at least one of the plurality of dummy gate drivers being located between some of the plurality of normal gate drivers.

2. The display device of claim 1 , wherein a gate signal for driving the pixels is output from the output terminal of each of the normal gate drivers, and the gate signal is not output from the output terminal of any of the dummy gate drivers.

3. The display device of claim 1 , wherein the output terminal of each of the dummy gate drivers is not electrically connected to any of the pixels nor another one of the gate drivers.

4. The display device of claim 1 , wherein each of the dummy gate drivers comprises an input terminal and at least one clock terminal, and a same signal is input to the input terminal and the clock terminal.

5. The display device of claim 4 , wherein each of the dummy gate drivers comprises a first power terminal to which a first gate voltage is input and a second power terminal to which a second gate voltage lower than the first gate voltage is input.

6. The display device of claim 5 , wherein the same signal is a constant voltage.

7. The display device of claim 6 , wherein the constant voltage is the first gate voltage.

8. The display device of claim 1 , further comprising:

a data driver in the non-display region, the data driver being electrically connected to the data lines.
