Display device and manufacturing method thereof |
摘要 |
It is an object of the present invention to prevent an influence of voltage drop due to wiring resistance, trouble in writing of a signal into a pixel and trouble in gray scales, and provide a display device with higher definition, represented by an EL display device and a liquid crystal display device. In the present invention, a wiring including Cu is provided as an electrode or a wiring used for the display device represented by the EL display device and the liquid crystal display device. Besides, sputtering is performed with a mask to form the wiring including Cu. With such structure, it is possible to reduce the voltage drop and a deadened signal.
