    Abstract: A display device includes a display substrate including a display area and a pad region, a first pad portion including a plurality of first pad terminals, the plurality of first pad terminals being arranged in a first direction, and a printed circuit board (PCB) including a base film and a second pad portion. The second pad is electrically connected to the first pad portion. The second pad portion includes a plurality of second pad terminals electrically connected to the plurality of first pad terminals, and a plurality of first test lines. The plurality of second pad terminals includes a plurality of sub-pad terminals. One of the plurality of first lines is connected to a first sub-pad terminal of the plurality of sub-pad terminals, and a second sub-pad terminal of the plurality of sub-pad terminals is not connected to any of the plurality of first lines.

    Abstract: A display device includes a substrate including a display area to display an image and a pad area disposed around the display area; and a first pad unit positioned on the pad area, and including a first terminal region having a plurality of first pad terminals arranged in a first direction, in which each of the plurality of first pad terminals includes: a plurality of first connection pad terminals arranged in a first row disposed at a first angle relative to the first direction; a plurality of second connection pad terminals spaced apart from the plurality of first connection pad terminals, and arranged in a second row disposed at a second angle relative to the first direction; and a first terminal connection line configured to connect one of the plurality of first connection pad terminals and one of the plurality of second connection pad terminals, and having at least one bent shape. The first terminal connection line is disposed in a different layer from that of the first connection pad terminal and the second connection pad terminal.

    Abstract: A display device includes a substrate and a first pad. The substrate includes a display area to display an image, and a pad area outside the display area. The first pad is in the pad area, and includes first pad terminals extending parallel to one another in a first direction. The first pad terminals include: first connection pad terminals arranged along a first column that forms a first slope angle with the first direction; second connection pad terminals spaced apart from the first connection pad terminals and arranged along a second column that forms a second slope angle with the first direction; and a first dummy pad terminal between a pair of adjacent first connection pad terminals among the first connection pad terminals along the first column. The first dummy pad terminal and the first connection pad terminals are in different layers than one another.

    Abstract: A display device includes a display substrate and a printed circuit board (PCB). The display substrate includes a display area to display an image, and includes a pad area outside the display area. The PCB is bonded to a surface of the display substrate in the pad area. The PCB includes a base film, first terminal wires positioned at the base film, second terminal wires positioned at the base film, first sub-pad terminals electrically connected to the first terminal wires through contact holes formed in the base film, and second sub-pad terminals directly and electrically connected to the second terminal wires without contact holes. The first sub-pad terminals and the second sub-pad terminals are alternately arranged. The first terminal wires and the second terminal wires are, in a view normal to the surface, spaced apart from one another.
