BANK REPAIR METHOD, ORGANIC EL DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF
First Claim
1. 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, repairing the bank having the defect portion 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, whereinthe dam, at a portion thereof with lowest height, satisfies (h/H)+0.1 W≧
1.5, 0.5≦
(h/H)≦
2.0, and 5≦
W≦
50, wherea 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 μ

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.
