Beschreibung
Zusammenfassung:	A display device includes a display panel on which a signal pad part including signal pads, indentation pads, resistance measurement pads, and alignment pads arranged in a first direction is arranged and a flexible printed circuit board on which a connection pad part including first, second, third, and fourth pads corresponding to the signal, indentation, resistance measurement, and alignment pads, respectively, arranged in the first direction is arranged. The signal, indentation, and resistance measurement pads are arranged in the first direction with a first interval and the first, second, and third pads are arranged in the first direction with a second interval which is smaller than the first interval. Accordingly, the present invention can accurately monitor a contact failure between the display panel and the flexible printed circuit board. 표시 장치는 제1 방향으로 배열된 신호 패드들, 압흔 패드들, 저항 측정 패드들, 및 얼라인 패드들을 포함하는 신호 패드부가 배치된 표시 패널 및 제1 방향으로 배열되어 상기 신호, 압흔, 저항 측정, 및 얼라인 패드들에 각각 대응하는 제1, 제2, 제3, 및 제4 패드들을 포함하는 연결 패드부가 배치된 연성 회로 기판을 포함하고, 상기 신호, 압흔, 및 저항 측정 패드들은 제1 간격을 두고 제1 방향으로 배열되고, 상기 제1, 제2, 및 제3 패드들은 상기 제1 간격보다 작은 제2 간격을 두고 상기 제1 방향으로 배열된다.
