摘要:
An active matrix substrate suppresses reduction in production yield and increase in production steps and simultaneously permits both sufficient securing of a storage capacity and improvement of an aperture ratio of a pixel. The active matrix substrate is an active matrix substrate and includes a thin film transistor disposed at an intersection of a scanning signal line with a data signal line on a substrate, the thin film transistor including a gate electrode connected to the scanning signal line, a source electrode connected to the data signal line, and a drain electrode connected to a drain lead-out wiring; a storage capacitor upper electrode connected to the drain lead-out wiring and a pixel electrode; and a storage capacitor wiring overlapping with the storage capacitor upper electrode through an insulating film, wherein the storage capacitor wiring has an extending portion overlapping with the drain lead-out wiring through the insulating film.
