Display device having compensating capacitors for different wiring lengths and method of manufacturing the same
Provided are a display device and a method of manufacturing the same. A display device comprises a display area, a non-display area, signal lines, and compensating capacitors. The display area and the non-display area are defined on a substrate. The signal lines are located within the display area, and their wiring lengths differ depending on location. The compensating capacitors are connected to at least one of the signal lines.
1. A display device comprising:
a display area and non-display area defined on a substrate;
signal lines whose wiring length differs depending on location, which are located within the display area; and
compensating capacitors each connected to at least one of the signal lines,
wherein adjacent N signal lines (N is an integer greater than or equal to 2) are combined into one group, and the compensating capacitor corresponding to the group converges to a single capacitance value.
2. The display device of claim 1 , wherein the compensating capacitors have a different capacitance value depending on the length of the signal lines.
3. The display device of claim 1 , wherein the compensating capacitors are formed so that parasitic capacitors existing between the signal lines have a capacitance value, with variation ranging from 1 to 20%.
4. The display device of claim 1 , wherein the compensating capacitors are arranged in non-display areas provided on the upper and lower sides of the display area.
5. The display device of claim 1 , wherein the compensating capacitors are arranged in non-display areas provided on the left and right sides of the display area.
6. The display device of claim 1 , wherein the compensating capacitors are arranged in non-display areas provided on the upper, lower, left, and right sides of the display area.
7. The display device of claim 1 , wherein one end of the compensating capacitors is connected to at least one of the signal lines, and the other end is electrically floating or connected to a power source.
8. The display device of any one of claim 1 , wherein the display panel has a curved shape.
9. The display device of any one of claim 1 , wherein the display panel has a circular shape.
10. The display device of any one of claim 1 , wherein the display panel has an elliptical shape.
11. A method for manufacturing a display device, the method comprising:
defining a display area and a non-display area on a substrate;
arranging signal lines whose wiring length differs depending on location, within the display area; and
forming compensating capacitors in such a manner that each compensating capacitor is connected to at least one of the signal lines,
wherein adjacent N signal lines (N is an integer greater than or equal to 2) are combined into one group, and the compensating capacitor corresponding to the group converges to a single capacitance value.
12. The method of claim 11 , wherein, in the forming of compensating capacitors, the compensating capacitors have a different capacitance value depending on the length of the signal lines.
