  • Patent number: 7674407
    Abstract: 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.

  • Publication number: 20060007520
    Abstract: A method of manufacturing an organic thin film element including an organic thin film between a pair of thin film electrodes with at least one transparent electrode includes forming the transparent electrode by atomizing a material liquid containing a transparent-electrode forming material onto a base material; and forming the organic thin film on the transparent electrode. The organic thin film element is capable of simply providing an organic thin film element having a long element life. A method of manufacturing an electro-optic device as well as a method of manufacturing electronic equipment by using the above method are described.
