摘要

Measure of forming an EL layer by selectively depositing through evaporation a material for forming the EL layer at a desired location is provided. When a material for forming an EL layer is deposited, a mask (113) is provided between a sample boat (111) and a substrate (110). By applying voltage to the mask (113), the direction of progress of the material for forming the EL layer is controlled to be selectively deposited at a desired location.
