A display apparatus includes a silicon oxide film and a silicon nitride film as a base layer placed on an insulating substrate, a polycrystalline silicon electrode placed on the base layer, a gate insulating film placed on the polycrystalline silicon electrode, and a gate metal electrode placed on the gate insulating film at a position opposite to the polycrystalline silicon electrode. The gate metal electrode partly or entirely covers the edge of the polycrystalline silicon electrode when viewed from the top.
