A method for manufacturing an organic electroluminescent display device including one or more organic electroluminescent elements arranged on a light-permeable substrate, each element having a cathode, an emitting layer made of one or more organic substances and an anode is capable of forming, at a high accuracy, an emitting layer with various patterns. The method includes the steps of: layering the anode material with a pattern on a light-permeable substrate; layering secondly in turn the one or more organic substances, the cathode material, the protective layer on the anode material and the light-permeable substrate; layering thirdly a resist layer on the layered protective layer to pattern the layered resist layer with a shape corresponding to the emitting layer; dry-etching the layered anode material, the layered one or more organic substances, the layered cathode material and the layered protective layer in accordance with the pattern of the resist layer; and repeating the second and third layering steps and the dry-etching step to make an arrangement of the one or more organic electroluminescent elements.

A method for forming a resonator in a semiconductor laser device comprises the steps of; filling with a resin a gap surrounding the side surfaces of the waveguide for a resonator other than the end-surface to be polished; polishing the end-surface and the resin surrounding it; forming a predetermined optical coating on the polished end-surface and the resin in the state of the laser waveguide and the electrode being embedded; and removing the embedding resin. Both the bending of polished end-surfaces and the entering of the thin film into the side surface of the laser waveguide is prevented so that a high smooth end-surface of mirror coating for resonator is achieved. Furthermore, any crystals are used for a substrate carrying a semiconductor laser structure with a resonator even if that crystal is of non-cleavage, according to that method.
