Abstract: The present invention discloses a method for processing a substrate on which transparent electrode made of metal oxide is formed before forming an organic EL element on the transparent electrode. According to the method, the substrate is accommodated in a bake chamber provided with a heater. The substrate is heated while mixed gas of oxygen and nitrogen is introduced into the bake chamber so as to replace the gas in the bake chamber. The mixed gas is introduced into the bake chamber in an amount that is 1/60 or more and 1/15 or less of a whole volume of the bake chamber per minute. According to this method, moisture is removed and an appropriate surface treatment is performed for the transparent electrode of metal oxide at the same time.

Abstract: An organic EL device having a large effective area with improved uniformity in luminescent brightness. A transparent first electrode, an organic EL layer, a second electrode, and a protective film are formed on a glass substrate. A conductive film is formed insulated from the second electrode. The conductive film, which covers the second electrode, is connected to opposite ends of the first electrode. One of the ends of the first electrode includes a connection terminal.

Abstract: A method for manufacturing an electroluminescence panel includes: forming a light emitting portion in each of a plurality of portions of a glass substrate; forming a protective layer of an inorganic material that can be cut apart by a scribe and break method to cover the light emitting portions; providing a scribe line on a surface of the glass substrate opposed to a surface in which the protective layer has been formed and at a position corresponding to the protective layer; and cutting the glass substrate and the protective layer along the scribe line in such a manner as to divide the glass substrate into a plurality of sections each including the light emitting portion. Thus, a scribe clearance for breaking the single glass substrate is decreased.

Abstract: An electrode of the organic EL device includes a substantially rectangular electrode region that contacts an organic layer, a terminal section to which an external drive circuit is connected, and a conductive section that electrically connects the terminal section to the electrode region. The conductive section includes a first joint connected to the terminal section, a second joint connected to the outer periphery of the electrode region, and a conductive section main body that extends between the first joint and the second joint to electrically connect the first joint to the second joint. Therefore, the difference of magnitude between currents flowing at respective positions in a luminous region in the organic EL device is lessened.

Abstract: A hydrogen storage electrode for use as an anode of an alkaline battery and a process for producing such electrode are disclosed. According to the process, firstly particles of hydrogen storage alloy powder with maximum particle size of 50 .mu.m is prepared. The alloy powder particles are then made into microcapsules by electroless plating with copper amounting to 10%-20% by weight with respect to the sum of the alloy powder and the plating copper. With an electric current collector placed in contact with the copper-plated alloy powder set in a die cavity of a molding press, the molding dies are closed to press and the copper-plated powder and the current collector for bonding them together thereby to form the hydrogen storage electrode. Pressure exerted during the pressing is applied to such an extent that the porosity of the resulting compact of the pressed alloy powder falls in the range of 10% to 25%.
