Abstract:
1. A display panel in which a drive IC chip including a circuit for driving a display region where an image is displayed is mounted on a panel substrate, the display panel comprising: a plurality of bump electrodes formed on a surface of the drive IC chip that faces the panel substrate; a plurality of electrode pads formed on the panel substrate such that the electrode pads are electrically connected to the bump electrodes; and an anisotropic conductive film that is interposed between the panel substrate and the drive IC chip and that electrically connects the bump electrodes and the electrode pads together, wherein the anisotropic conductive film is arranged to extend beyond all side surfaces other than one specific side surface of the drive IC chip, the drive IC chip is formed substantially in a shape of a quadrangular prism, the anisotropic conductive film is arranged to extend beyond the three side surfaces other than the one specific side surface, and when accuracy with which the drive IC chip is mounted on the panel substrate, in a direction perpendicular to the specific side surface, is ±a mm, and accuracy with which the anisotropic conductive film is bonded to the panel substrate, in the direction perpendicular to the specific side surface, is ±b mm, a distance of d mm from the specific side surface to at least one of the bump electrodes arranged closest to the specific side surface satisfies equation (1) below
