Abstract

본 발명은 칼라 음극선관용 섀도우마스크를 개시한다.The present invention discloses a shadow mask for color cathode ray tubes.

본 발명은 소정의 패턴으로 다수의 전자빔 통과공이 형성된 유공부와, 이 유공부의 가장자리로부터 연장되는 무공부와, 이 무공부로부터 수직 하방으로 절곡된 스커트부를 구비하여 구성된 칼라 음극선관용 섀도우마스크에 관한 것으로, 상기 유공부가 평면으로 이루어진 평면 영역으로 이루어지고 이 평면영역 상호간의 경계부가 소정의 각도로 절곡된 것에 그 특징이 있으며, 이는 섀도우마스크의 열팽창에 따른 도밍현상을 방지할 수 있는 이점을 가진다.The present invention relates to a shadow mask for a color cathode ray tube comprising a hole formed with a plurality of electron beam through holes in a predetermined pattern, a hole extending from an edge of the hole, and a skirt bent vertically downward from the hole. It is characterized in that the perforated part is made of a planar region consisting of a plane and the boundary portions between the planar regions are bent at a predetermined angle, which has an advantage of preventing the ming phenomenon due to thermal expansion of the shadow mask. .
