More Information
Summary:A display device includes: a pixel array disposed in a display area; a connection pad disposed in the pad area; a transfer wire electrically connected to the connection pad to transfer a driving signal or power to the pixel array. The connection pad includes: a conductive dummy pattern disposed under the transfer wire; a pad conductive layer disposed on the transfer wire and electrically connected to the transfer wire; and a passivation layer disposed on the pad conductive layer, covering at least side surfaces of the pad conductive layer, and including an opening overlapping the conductive dummy pattern and the transfer wire. 표시 장치는 표시 영역에 배치되는 화소 어레이, 패드 영역에 배치되는 연결 패드, 연결 패드와 전기적으로 연결되어 화소 어레이에 구동 신호 또는 전원을 전달하는 전달 배선을 포함하고, 연결 패드는, 전달 배선 아래에 배치되는 도전성 더미 패턴, 전달 배선 위에 배치되며, 전달 배선과 전기적으로 연결되는 패드 도전층 및 패드 도전층 위에 배치되며, 패드 도전층의 적어도 측면을 커버하고, 도전성 더미 패턴 및 전달 배선과 중첩하는 개구를 포함한 패시베이션층을 포함한다.
