Display device

A display device comprising:

• a substrate comprising:
• a display area comprising:
• pixels comprising a first pixel array, a second pixel array, and a third pixel array respectively representing different colors;
• and
• signal lines comprising a first signal line connected to the first pixel array, a second signal line connected to the second pixel array, and a third signal line connected to the third pixel array;
• and
• a peripheral area around the display area, and comprising a fan-out portion comprising:
• a first fan-out wire in a gate conductive layer above the substrate, on a gate-insulating layer that is above a buffer layer, and connected to the first signal line;
• a second fan-out wire in a first conductive layer above the substrate, below the buffer layer, and connected to the second signal line;
• and
• a third fan-out wire in a second conductive layer above the substrate, between the first conductive layer and the buffer layer, and connected to the third signal line.

A display device comprising:

• a substrate comprising:
• a display area comprising pixels and signal lines;
• and
• a peripheral area positioned around the display area, and comprising a fan-out portion in which fan-out wires are connected to the signal lines to transmit signals of different voltage ranges;
• and
• a first conductive layer above the substrate;
• a second conductive layer above the first conductive layer;
• a buffer layer above the second conductive layer;
• a gate-insulating layer above the buffer layer;
• and
• a gate conductive layer positioned above the substrate and on the gate-insulating layer,
• wherein the first conductive layer, the second conductive layer, and the gate-insulating layer have respective sheet resistances or specific resistances, and
• wherein the fan-out wires are positioned on respective ones among the first conductive layer, the second conductive layer, and the gate conductive layer depending on a magnitude of voltage ranges of the signals respectively transferred by the fan-out wires.
