Abstract
The fabrication method for an organic EL device according to the invention includes: forming a third insulating layer on a first insulating layer; removing the third insulating layer in a first pixel region by etching the third insulating layer; forming a second insulating layer that has different thicknesses in a first pixel and a second pixel and has a flat first surface by forming a precursor insulating layer to continuously cover a first reflection film and a second reflection film and then planarizing an upper surface of the precursor insulating layer; and forming a first pixel electrode and a second pixel electrode on the first surface of the second insulating layer. The first insulating layer is slower in the rate at which the layer is removed by etching than the third insulating layer.
