摘要： A display device including a first substrate including a display area and a non-display area, a circuit film connected to the first substrate, a printed circuit board (PCB) connected to the circuit film, and a first inspection pad, a second inspection pad, and a third inspection pad located in the non-display area and a bridge configured to electrically connect the first inspection pad, the second inspection pad, and the third inspection pad. The circuit film includes a first line electrically connected to the first inspection pad, a second line electrically connected to the second inspection pad, a third line electrically connected to the third inspection pad, and a branch point configured to branch at least one line from the first line, the second line, and the third line into two sub-lines. The PCB includes a test pad unit connected to the first line, the second line, and the third line.

摘要： 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 front 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.
