Claim Text:
1. A manufacturing method of a light-transmitting conductive film, comprising: forming a light-transmitting conductive film on an insulating layer by a sputtering method in an atmosphere including a rare gas; and performing heat treatment on the light-transmitting conductive film, wherein the light-transmitting conductive film is electrically connected to one of a source electrode and a drain electrode of a transistor through an opening in the insulating layer, wherein the light-transmitting conductive film comprises conductive oxynitride including zinc and aluminum, wherein the sputtering method is carried out using a target including zinc oxide and aluminum over which a chip of aluminum nitride is set, and wherein an amount of aluminum included in the chip of aluminum nitride is larger than an amount of aluminum included in the target including the zinc oxide and the aluminum.
