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 partitioning 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.
Claims17
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 comprising:
- examining whether or not a bank having a defect portion is present;
- and
- when a bank having a defect portion is present, 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 partitioning 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.
An organic electroluminescence (EL) display device comprising:
- a substrate;
- banks formed over the substrate;
- and
- light-emitting layers disposed in concave spaces defined by the banks, wherein
- a dam is disposed in each of adjacent concave spaces between which a bank having a defect portion is located, a dam disposed in a concave space partitioning a light-emitting layer disposed in the concave space into a first light-emitting layer in a vicinity of the defect portion and a second light-emitting layer outside the vicinity of the defect portion.
A method for manufacturing an organic EL display device by forming banks over a substrate and forming light-emitting layers in concave spaces defined by the banks, the method comprising:
- examining whether or not a bank having a defect portion is present;
- when a bank having a defect portion is present, forming a dam in each of adjacent concave spaces between which the defect portion is located, a dam formed in a concave space partitioning 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;
- and
- forming the light-emitting layers after forming the dam.
