Abstract
Provided is a method for manufacturing a flexible film. The method for the manufacturing the flexible film includes providing a parent film on which a plurality of film areas are defined, each of which having a detection pattern formed thereon, applying a voltage to each of the film areas to detect whether a defect exists, removing the detection pattern from respective ones of the film areas on which the defect is detected, and cutting out others of the film areas on which the defect is not detected.

A film package comprising:
- a base substrate having light transmission and flexibility, and on which a plurality of film areas are arranged in one direction, the film areas each comprising a line area, and a test area;
- a plurality of circuit lines at the line area;
- and
- a detection pattern at a test area, comprising a material having a light absorption property, and configured for removal when a defect test determines that a defect exists.
