An organic semiconductor element part formed on a substrate is covered with a planarizing layer, a radiator plate is fixed with an adhesive layer on the planarizing layer, and a shield layer intercepting the adverse effects exerted on the organic semiconductor element part during the curing of the adhesive layer is formed between the adhesive layer and the planarizing layer. When the adhesive layer is a photo-curing adhesive layer, the shield layer prefers to intercept the light used for curing the photo-curing adhesive layer. When the adhesive layer is a thermosetting adhesive layer, the shield layer prefers to intercept the outgassing occurring during the curing of the thermosetting adhesive layer. By adopting this configuration, it is made possible to accomplish infallible interception of oxygen and moisture and effect radiation of heat with high efficiency. It is further made possible to suppress the adverse effect induced during the adhesion of the radiator plate and prevent the organic semiconductor element part (organic EL element) from being deteriorated.

A method for manufacturing an organic thin film element that includes an organic thin film between a pair of thin film electrodes and at least one electrode being a transparent electrode includes forming a transparent electrode by spraying a material liquid containing a transparent electrode formation material on a base material, and forming an organic thin film on the transparent electrode. This method allows for the manufacture of the organic thin film element by which an organic thin film element with high light-extraction efficiency is simply provided. A method for manufacturing an electro-optic device and a method for manufacturing electronic equipment that utilize the method for manufacturing an organic thin film element are described.

Method for manufacturing microlens and method for manufacturing organic electroluminescence element

An organic electroluminescence element having a thin film of organic compound containing at least a light-emitting layer interposed between an anode and a cathode is disclosed. This element is driven by utilizing the sheet resistance of the anode or the cathode in a manner such that the distribution of brightness or color in a single light-emitting plane is modulated with the elapse of time. For example, at least either of the anode and the cathode is furnished with not less than two connecting parts, voltages are applied severally to the connecting parts, and at least one of the factors, i.e. amplitude, frequency, phase, and offset of the voltage applied to each of the connecting parts is modulated. As a result, a completely novel organic electroluminescence element that is capable of causing the brightness and the color to be so modulated as to induce waving in a single light-emitting plane can be realized.

Fullerene compounds such as C60 are dissolved into solvents such as toluene in concentration of 1.times.10-3 mol/L or more. When the solution is coagulated, fullerene associated bodies are formed. After the re-dissolution of the solution, the associated bodies are excited by laser beam, and the resultant is cluster compounds of fullerene having specific number of monomers, such as 23 and 53. The cluster is stable and separable from the solution.
