Abstract: Provided are a printed circuit board, a display device and a method of manufacturing a display device. The printed circuit board includes a base film including a first surface and a second surface, lead lines disposed on the first surface of the base film, and a first cover layer that covers at least a part of the lead lines and includes fill-in portions disposed between the lead lines. Each of the fill-in portions has a surface height less than a surface height of each of the lead lines with respect to the first surface of the base film.
