Abstract: A display device includes a display panel including a plurality of panel pads, and a panel alignment mark adjacent to the plurality of panel pads. A connection circuit board is connected to the display panel. The connection circuit board includes a plurality of input/output pads and a plurality of dummy pads adjacent to the plurality of input/output pads. Some of the plurality of dummy pads overlap the panel alignment mark in a thickness direction of the display device

Abstract: A display device includes a display panel having a display region and a pad region. A pad portion is disposed in the pad region. A circuit substrate is electrically connected to the pad portion. An anisotropic conductive film is interposed between the pad portion and the circuit substrate. The pad portion includes a first pad of which a lateral side and a Y axis form a first angle greater than 0°. The anisotropic conductive film includes conductive particles. The conductive particles are disposed at vertices of an imaginary quadrangle having a length of a first diagonal line shorter than a length of a second diagonal line when viewed from above. The second diagonal line and the Y axis form a second angle greater than 0°. The first angle and the second angle are acute angles. The first angle is greater than the second angle.
