Abstract: A method for repairing a bank during manufacture of an organic EL display device when a bank defect portion is produced due to collapsing of a bank, a foreign particle, or the like. The method includes: detecting a defect portion of a lengthwise bank formed over a ground substrate; and when a defect portion is detected, forming, in each of adjacent concave spaces between which the lengthwise bank having the defect portion is located, a dam partitioning the concave space into a first space in a vicinity of the bank defect portion and a second portion not in the vicinity of the bank defect portion. The shape of the dam is configured so that in ejecting organic functional layer ink in each concave space with a nozzle head, there is an ink dropping point in each of the first space and the second space.

Abstract: An examination is performed of whether or not a bank having a defect portion is present. When a bank having a defect portion is present, the bank having the defect portion is repaired by forming a dam in each of adjacent concave spaces between which the bank having the defect portion is located. A dam formed in a concave space partitions the concave space into a first space in a vicinity of the defect portion and a second space outside the vicinity of the defect portion. The dam, at a portion thereof with lowest height, satisfies (h/H)+0.1W≧1.5, 0.5≦(h/H)≦2.0, and 5≦W≦50, where a ratio of the height h of the dam to a height H of the banks is denoted as h/H, and a width of the dam is denoted as W μm.

Abstract: A bank repair method for repairing a defect portion of a bank in a process of manufacturing an organic electroluminescence (EL) display device including a substrate, banks formed over the substrate, and light-emitting layers formed in concave spaces defined by the banks. The bank repair method includes: examining whether or not a bank having a defect portion is present; and when a bank having a defect portion is present, repairing the bank by applying a repair material containing a gas adsorbent to the defect portion and curing the repair material; and after curing the repair material, baking the repair material by irradiating the repair material with infrared laser light.

Abstract: An organic electroluminescence (EL) element that has an anode; a cathode; an organic light-emitting layer between the anode and the cathode that emits light according to recombination of holes injected from the anode and electrons injected from the cathode; and an electron transport layer between the cathode and the organic light-emitting layer that transports electrons from the cathode to the organic light-emitting layer. The electron transport layer includes an n-type dopant that includes an electron-donating substance, the electron transport layer being doped with the n-type dopant at a doping concentration that is higher than a doping concentration at which light emittance efficiency of the organic light-emitting layer is greatest.
