Abstract: 본 발명은 전자파 필터가 구비된 영상 표시 장치에 관한 것으로, 별도의 구동 수단을 사용하지 않으면서 영구적으로 전자파를 차단하는 효과를 향상시키도록, 공기 유동이 가능한 통공이 다수개 천공되며, 내부에 분말 방식으로 가공된 전기석이 충진된 필터 봉; 그리고 소정 형상의 필터 프레임에서 필터 봉이 정렬되는 전자파 억제 필터가 상기 영상 표시 장치 내부의 고온의 열 유동 경로 상에 설치되는 바, 바람직하게는 전자파 억제 필터가 영상 표시 장치에서 고열이 배출되는 방열구에 설치되는 전자파 필터가 구비된 영상 표시 장치를 제공하여, 외부의 구동 수단을 필요로 하지 않으면서 영상 표시 장치에서 필연적으로 방출되는 고온의 열을 전기석과 접촉시켜 음이온을 활성화시키므로 영상 표시 장치 내부의 전자파가 중화되어 방출이 억제되고, 무동력 상태에서 전자파를 억제하므로 사용자의 신체 기능에 피해를 주는 것을 방지하는 효과가 있다.
