Method of manufacturing organic EL panel, organic EL panel, and electronic apparatus
There is provided a method of manufacturing an organic EL panel by using a mask that includes a blocking portion blocking incoming particles and a plurality of opening portions through which the incoming particles can pass. The method includes forming a first light emitting part corresponding to a first color on a substrate by using a first mask, forming a first electrode that is overlapped with the first light emitting part by using the first mask, forming a second light emitting part corresponding to a second color on the substrate next to the first light emitting part so as to cover at least a part of the first electrode by using a second mask, forming a third light emitting part corresponding to a third color on the substrate in a position for facing the second light emitting part with the first electrode interposed therebetween in the plan view so as to cover at least a part of the first electrode or the second light emitting part, by using a third mask, forming a second electrode in an area corresponding to the second light emitting part and the third light emitting part by using a fourth mask, and removing a material that is deposited on the first electrode and the second electrode by using the first electrode and the second electrode as a mask.
