Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a flat display panel for improved production yield by inspecting/correcting a defect before a conductive material film is patterned, so that the cause of an abnormal process is inferred based on the defect information for correcting the process without delay, resulting in prevented occurrence of a defect with a linear pattern electrode. SOLUTION: There are provided a process where the conductive material film is formed on a substrate, an inspection means for inspecting the film before the process for patterning, a delivery means for carrying out the substrate based on the inspection result, and a defect correcting means for the defects occurring at the film. Based on the inspection result with the film, delivery of the substrate and correction of defects are performed.
