Abstract
An optical device used as an image panel which is allowed to be arranged together with the adjacent one on a display without a gap put therebetween and which is improved to form a stacked body including organic layers without damaging the surface of an already-formed organic layer by a vapor-deposition mask, and a method of manufacturing the optical device. Metal bumps are provided on stripes of transparent electrodes arranged on a glass substrate in such a manner as to be located in non-optical operation regions, and are led on the back surface of the organic EL device. The metal bumps function as spacers upon vapor-deposition of the organic layer or the like, to prevent the contact of a vapor-deposition mask with an already-formed film surface, and are led on the back surface of the organic EL device together with metal electrodes and are connected to an electronic part mounted on the back surface side of the organic EL device.
