摘要：
The invention provides a display device and a method for manufacturing thereof by increasing a material efficiently as well as simplifying steps. Also, the invention provides a technique for forming a pattern such as a wiring, that is used for forming a display device, to have a predetermined shape with an excellent controllability. The method for manufacturing a display device includes the steps of: forming a lyophobic region; selectively irradiating laser beam in the lyophobic region to form a lyophilic region; selectively discharging a composition, that contains a conductive material, in the lyophilic region to form a gate electrode layer; forming a gate insulating layer and a semiconductor layer over the gate electrode layer; discharging a composition containing a conductive material over the semiconductor layer to form a source electrode layer and a drain electrode layer; and forming a pixel electrode layer on the source or drain electrode layer.
