DISPLAY DEVICE AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a structure for a semiconductor device for achieving low power consumption and improvement in yield and reliability even when a screen is enlarged, and to provide a method of producing the same.SOLUTION: A pixel thin-film transistor used in a screen is produced by using a reverse-stagger type thin-film transistor. In the reverse-stagger type thin-film transistor, a source wire and a gate electrode are produced on the same plane. In addition, metal wires connecting between the source wire and the reverse-stagger type thin-film transistor, and between the pixel electrode and the reverse-stagger type thin-film transistor are produced at the same step.
