Abstract: 본 발명은 TV나 모니터 및 각종 표시장치의 플라즈마 표시 평판(피디피; PDP) 장치에서 전면 유리판에 설치되는 전극 구조이다. 기존의 공면 전극 AC형 피디피는 전면 유리판의 평면상에 방전유지전극이 도포되고 후면판에 신호전극과 격벽이 설치된다. 본 발명은 기존의 AC-PDP에서 생판의 방전유지전극을 개량하여 이중층의 방전유지전극의 구조이다. 즉, 유리판에 투명전극과 전원 연결용 버스전극을 도포하고 그 위에 유전층을 도포하는 방식은 종래 공면형 AC-PDP 전면판의 전극구조와 동일하다. 본 발명은 그러한 전면판의 유전층 위에 추가적으로 불투명 재료의 전극을 단위 방전 화소의 외곽에 수 10 미크론의 높이로 설치하고 전극면 위에 국한하여 유전층을 도포한다. 결과적으로 종래의 투명전극면 위의 유전층이 바닥면이 되고 유전층 위의 외곽에 격벽전극으로 구성된 상자형의 공간을 형성한다. 2개의 층으로 분리된 전극은 전체 패널의 가장자리에서 하나로 이어져서 동일한 전압이 공급되도록 한다. 본 발명은 적당한 전극 간격을 갖는 투명전극 면 사이에서 방전이 유지되며, 유전층 윗면에 상당한 높이의 상자형 벽면 전극에 의하여 방전 공간을 최대한 확보하고 플라스마를 가두는 효과를 위하여 고안되었다. 따라서 기존의 단순 공면 전극구조를 개량하여 3차원의 방전유지전극 구조로서 플라스마의 발생이 용이하고 플라스마의 량이 많고 외곽으로의 플라스마의 손실이 적어서 방전효율의 증대 효과를 갖는다.
