Abstract
A display device includes a display panel, a printed circuit board, a plurality of semiconductor devices which are film-like substrates with an IC chip, and a monolithic anisotropic conductive film disposed on the printed circuit board. Each of the semiconductor devices has a first side portion and a second side portion opposite to the first side portion. The first side portion is connected to the printed circuit board via the monolithic anisotropic conductive film, and the second side portion is connected to the display panel. Further the first side portion of each of the semiconductor devices is respectively connected at separated portions of the monolithic anisotropic conductive film.
