摘要：
In a pixel portion, a scan signal line and an auxiliary capacitor line are formed using a second conductive film, and a data signal line is formed using a first conductive film. In a TFT portion, a gate electrode is formed using the first conductive film and electrically connected to the scan signal line formed using the second conductive film through an opening in a gate insulating film. Further, a source electrode and a drain electrode are formed using the second conductive film. In the auxiliary capacitor portion, the auxiliary capacitor line formed using the second conductive film serves as a lower electrode, the pixel electrode serves as an upper electrode, and the passivation film used as a dielectric film is interposed between the capacitor electrodes.
