BANK REPAIR METHOD, ORGANIC EL DISPLAY DEVICE, AND PRODUCTION METHOD FOR SAME
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, 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.

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.
