Abstract

본 발명은 칼라 음극선관용 섀도우마스크를 개시한다. 본 발명은 다수의 전자빔 통과공이 형성된 유공부와, 이 유공부의 가장자리로부터 소정길이 연장되는 무공부와, 이 무공부로부터 직각으로 절곡된 스커트부를 구비하여 된 음극선관용 섀도우마스크에 관한 것으로 무공부와 스커트부의 절곡부에 이를 따라 소정 깊이와 폭을 가진 홈이 형성된 것에 특징이 있으며, 섀도우마스크의 포밍시 스커트부의 스프링 백 현상을 방지할 수 있는 이점을 가진다.The present invention discloses a shadow mask for color cathode ray tubes. The present invention relates to a shadow mask for a cathode ray tube comprising a hole formed with a plurality of electron beam through holes, a hole extending a predetermined length from an edge of the hole, and a skirt portion bent at right angles from the hole. A groove having a predetermined depth and width is formed along the bent portion of the skirt portion, and has an advantage of preventing spring back phenomenon of the skirt portion when forming the shadow mask.
