发明名称 ELECTRO LUMINESCENCE PANEL AND METHOD FOR MANUFACTURING ELECTRO LUMINESCENCE PANEL
摘要 The present invention provides an organic EL panel and a manufacturing method of the organic EL layer which can slow the reduction in the light emission lifetime of an organic layer and allow a short-circuit defect to be repaired. Organic EL elements include: an organic EL element including a short-circuit portion, and an altered portion formed to be highly resistive by irradiating a cathode with a laser beam; and an organic EL element which does not include the short-circuit portion. In the organic EL element, an organic EL layer emits light when a voltage higher than or equal to a first voltage is applied. In the organic EL element, the organic EL layer emits light when a voltage higher than equal to a second voltage that is higher than the first voltage is applied.

主权项 1. An organic electroluminescence (EL) panel comprising organic EL elements arranged in a matrix and each including an anode, a cathode, and an organic EL layer provided between the anode and the cathode, wherein the organic EL elements include: an abnormal element including: a short-circuit portion at which the anode and the cathode short-circuit; and a resistive portion which is (i) formed to be highly resistive by irradiating at least one of the anode, the organic EL layer, and the cathode with a laser beam, and (ii) positioned on a current pathway between the short-circuit portion and one of the anode and the cathode; anda normal element which does not include the short-circuit portion, in the normal element, the organic EL layer (i) emits light when a voltage higher than or equal to a first voltage is applied between the anode and the cathode, and (ii) does not emit light when a voltage lower than the first voltage is applied between the anode and the cathode, and in the abnormal element, the organic EL layer (i) emits light when a voltage higher than or equal to a second voltage is applied between the anode and the cathode, and (ii) does not emit light when a voltage lower than the second voltage is applied between the anode and the cathode, the second voltage being higher than the first voltage.
