Abstract: 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.
