Semiconductor device and display unit

A display unit provided with a semiconductor device and a display element layer that is configured to be driven by the semiconductor device, the semiconductor device comprising:

• a substrate;
• a transistor including a semiconductor film, a gate insulating film, a first gate electrode, and a second gate electrode, the semiconductor film, the gate insulating film, and the first gate electrode being provided in this order from the substrate, the second gate electrode facing the first gate electrode across the semiconductor film;
• a storage capacitor including a lower electrode and an upper electrode, the lower electrode and the upper electrode being provided in this order from the substrate, the upper electrode facing the lower electrode and including a material a same as a material of the semiconductor film;
• a first insulating layer provided between the second gate electrode and the semiconductor film;
• and
• a second insulating layer provided between the lower electrode and the upper electrode and having a thickness smaller than a thickness of the first insulating layer.
