Patent ID: 7781759

Claim:
A method for manufacturing a display device, comprising: providing an insulating substrate; forming a plurality of gate lines on the insulating substrate, the plurality of gate lines including a plurality of gate electrodes; forming a gate insulating layer on the insulating substrate, the gate insulating layer covering the plurality of gate lines; depositing sequentially a lower layer on the gate insulating layer and an upper layer on the lower layer; patterning the upper layer and the lower layer to form a plurality of data lines, a plurality of source electrodes and a plurality of drain electrodes being spaced apart from each other to define a channel region disposed therebetween, and a plurality of pixel electrodes simultaneously, wherein the data lines comprise the lower layer and the upper layer and wherein the source electrodes, the drain electrodes, and the pixel electrodes comprise the lower layer; and forming organic semiconductor layers on the channel regions for each pixel and overlapping portions of the source electrode and drain electrode, wherein the organic semiconductor layer, the source electrode, and the drain electrode form a transistor along with the gate electrode.
