Abstract:
1. 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 across 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 to drain lines connected thereto respectively; a plurality of gate driver circuits provided along a second edge of the substrate and applying a control signal to the 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; a plurality of pads electrically connected to the circuit board and formed at the first edge of the substrate, the plurality of pads including a drain driver power supply pad; a plurality of bumps electrically connected to the pads and formed at the drain driver circuits; and a plurality of lines formed on the substrate and extended toward the second edge from the first edge, 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 a scan clock signal to the gate driver circuits, wherein the drain driver power supply pad electrically connects with a group of bumps of the plurality of bumps, and wherein a width of the drain driver power supply pad is larger than a width of the group of bumps.
