Display device and method for manufacturing the same

A display device, comprising:

• an insulating substrate;
• a plurality of gate lines formed on the insulating substrate, the plurality of gate lines including a plurality of gate electrodes;
• a gate insulating layer covering the plurality of gate lines;
• a plurality of data lines formed on the gate insulating layer and comprising a lower layer and an upper layer;
• a plurality of source electrodes and a plurality of drain electrodes formed on the gate insulating layer and being spaced apart from each other to define a channel region disposed therebetween;
• an organic semiconductor layer formed on the channel region for each pixel, and physically in contact with the source electrode and the drain electrode, a predetermined portion of the organic semiconductor layer overlapping portions of the source electrode, and the drain electrode, to form a transistor along with the gate electrode;
• and
• a plurality of pixel electrodes formed directly on the gate insulating layer,
• wherein the source electrodes, the drain electrodes, and the pixel electrodes are formed with the same layer as the lower layer of the data lines.
