Driving method for display device

A display device comprising:

• a substrate comprising a plurality of gate lines extended in a first direction, a plurality of drain lines extended in a second direction transverse to the first direction, and a plurality of pixels comprising switching elements respectively and arranged along the first direction and the second direction;
• a plurality of drain driver circuits provided along a first edge of the substrate and each applying gray scale voltage signals on the basis of display data signals acquired thereby to the switching elements of a group of the plurality of pixels corresponding thereto through a group of the plurality of drain lines connected thereto respectively;
• a plurality of gate driver circuits provided along a second edge of the substrate and each controlling the switching elements of the plurality of pixels through the plurality of gate lines;
• a circuit board provided along the first edge of the substrate and comprising a drain driver power supply line for supplying power to the plurality of the drain driver circuits in parallel;
• a plurality of pads electrically connected to the circuit board and formed at the first edge of the substrate;
• and
• a plurality of lines extended toward the second edge from the first edge and formed on the substrate,
• wherein the circuit board comprises a plurality of lines for supplying the signal to the gate driver circuits,
• wherein the plurality of lines on the substrate comprises a first line for supplying the power to the gate driver circuits and a second line for supplying the scan clock signal to the gate driver, which are connected to the pads,
• wherein the distance between the first line and the second line broadens on the way of their lines on the substrate, and
• wherein the first line and the second line comprise a part where an angle is formed between a third direction to which the first line extends and a fourth direction to which the second line extends.
