Abstract
A flexible printed circuit board includes a base film made of an insulating material, a power application wiring disposed on a first surface of the base film, a bypass wiring disposed on a second surface, opposite the first surface, of the base film, a first connection wiring which electrically connects the power application wiring to the bypass wiring, a second connection wiring spaced apart from the first connection wiring and which electrically connects the power application wiring to the bypass wiring, and a first cover film disposed on the first surface of the base film to cover at least a first portion of the second connection wiring. At least a first portion of the first connection wiring is exposed through the first cover film.
Claims22
A flexible printed circuit board comprising:
