An active matrix substrate includes a load circuit including a first active element performing a switching operation of a load, the first active element including a semiconductor film of a substantially polycrystalline state; a drive circuit including a second active element controlling driving the load, the second active element including a semiconductor film of a substantially single crystalline state, a hole being provided to one of a part and a peripheral part of the semiconductor film, the hole functioning a starting point for crystallizing the semiconductor film; and a substrate on a same plane of which the load circuit and the drive circuit are formed.
