A display device includes an array substrate including a display area and a non-display area, a driving circuit chip disposed on the non-display area and including a bottom surface, a top surface, a first pair of side surfaces extending in a first direction, and a second pair of side surfaces extending in a second direction perpendicular to the first direction, and first, second, and dummy bumps, each disposed on the bottom surface in a single column along the first direction, in which the dummy bumps include first and second dummy bump groups disposed between the first and second bumps along the first direction, the dummy bumps in the first dummy bump group are spaced apart from each other by a first pitch, and the dummy bumps in the second dummy bump group are spaced apart from each other by a second pitch different from the first pitch.

Display device

A display device includes a substrate including a wiring portion, a pad unit provided on the substrate and extended from the wiring portion, an integrated circuit chip electrically connected to the pad unit and mounted on the substrate, and an anisotropic conductive film configured to electrically connect the pad unit and the integrated chip to each other. The anisotropic conductive film includes an adhesive layer provided between the pad unit and the integrated circuit chip and at least one conductive ball scattered in the adhesive layer. A heat generator is also provided on the substrate. The heat generator is configured to come into contact with the anisotropic conductive film to supply heat to the anisotropic conductive film.
