Abstract

A non-quadrangular display includes a plurality of gate lines and a plurality of signal supply lines connected to the gate lines through corresponding contact points from among a plurality of contact points, and a difference between linear loads based on the signal supply lines and the gate lines connected to two contact points that have a similar symmetrical relationship from among the plurality of contact points is less than a set threshold value.

Claims

1. A non-quadrangular display comprising:

a plurality of gate lines extending along a first direction;

a plurality of signal supply lines extending along a second direction crossing the first direction, and connected to respective ones of the gate lines through corresponding contact points from among a plurality of contact points; and

a display unit comprising a plurality of pixels connected to the gate lines,

wherein the signal supply lines are configured to transmit gate signals to the gate lines via the plurality of contact points.

2. The non-quadrangular display of claim 1, wherein

the two corresponding contact points are provided at a same distance in the first direction with respect to a center of the display unit and are adjacent in the second direction.

3. The non-quadrangular display of claim 1, wherein

a layer on which the gate lines are formed is different from a layer on which the signal supply lines are formed.

4. The non-quadrangular display of claim 1, further comprising

a plurality of data lines extending along the second direction and connected to corresponding pixels from among the plurality of pixels.

5. The non-quadrangular display of claim 1, wherein

6. The non-quadrangular display of claim 5, wherein

the contact points include a plurality of first contact points provided on a first side with respect to a center of the display unit and a plurality of second contact points provided on a second side with respect to the center thereof.

7. The non-quadrangular display of claim 6, wherein

the first contact points become further distant from the center in the first direction and are arranged with each other in the second direction.

8. The non-quadrangular display of claim 6, wherein

the second contact points become further distant from the center in the first direction and are arranged with each other in the second direction.

9. The non-quadrangular display of claim 6, wherein the first contact points comprise one of the two corresponding contact points, and the second contact points comprise another one of the two corresponding contact points.

10. A non-quadrangular display comprising:

a plurality of gate lines;

a display unit including a plurality of pixels connected to the gate lines;
