Abstract: A display device includes a switching transistor, a driving transistor, a storage capacitor connected to the switching and driving transistors, and an organic light-emitting diode connected to the driving transistor. The driving transistor is connected to the switching transistor. The driving transistor includes a semiconductor layer having a channel region, first doped regions at sides of the channel region, and second doped regions doped with impurities of a concentration greater than the first doped regions. A first electrode layer is over an insulating layer, which covers the semiconductor layer. The electrode layer includes convex portions extending toward the first doped regions and covering an end of the channel region. At least one of the convex portions has a width greater than or equal to a width of the end of the channel region.

Abstract: Provided is a method of manufacturing a thin-film transistor substrate, the method includes forming a semiconductor pattern layer on a substrate. A first insulating film is formed on the semiconductor pattern layer. A metal pattern layer including a gate electrode and first and second alignment electrodes respectively spaced apart from two sides of the gate electrode is formed on the first insulating film. A cover layer covering the gate electrode is formed. The first and second alignment electrodes are removed. A first doping process is performed by doping the semiconductor pattern layer with a first impurity by using the cover layer as a mask. The cover layer is removed. A second doping process is performed by doping the semiconductor pattern layer with a second impurity having a lower impurity concentration than the first impurity by using the gate electrode as a mask.
