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 including a first signal pad portion including first signal pads, a second signal pad portion including second signal pads, and a first dummy pad portion disposed between the first signal pad portion and the second signal pad portion and including at least one first dummy pad, and a flexible circuit board including a first terminal portion including first terminals, a second terminal portion including second terminals, and a first cut portion disposed between the first terminal portion and the second terminal portion. The flexible circuit board is compressed to the display panel. The first terminals are electrically connected to the first signal pads. The second terminals are electrically connected to the second signal pads. The first cut portion overlaps the first dummy pad portion.
