Abstract
A display apparatus includes a display panel, a driving integrated circuit (IC), and an anisotropic conductive film. The display panel includes a non-display area adjacent to a display area and an upper substrate and a lower substrate. The driving IC overlaps the non-display area. The anisotropic conductive film attaches the driving IC to the lower substrate and includes conductive balls with diameters that gradually increase toward the display area.
