  4. 제3항에 있어서, 상기 다중극렌즈는 4중극렌즈인것을 특징으로하는 컬러디스플레이 시스템.
  5. 3색 전자비임을 발생하여 통로를 따라 스크린에 주사하는 전자총을 구비하고, 상기 전자총은 비임성형부를 구성하는 전극과 주집속렌즈를 형성하는 전극으로 이루어진 음극선관에 있어서, 상기 전자총의 내부에는 비임성형부와 각 전자비임 경로상의 주집속렌즈와의 사이에서 다중극렌즈를 형성하는 전극(42)(44)이 설치되고, 상기 다중극렌즈 형성 전극은 제1의 다중극렌즈 전극(42)과 제2의 다중극렌즈 전극(44)을 가지며, 상기 제2의 다중극렌즈 전극은 상기 주집속렌즈 형성전극 (44)(46)중 하나의 일부이고, 상기 제1의 다중극렌즈전극은 제2의 다중극렌즈전극과 비임성형부 사이에서 제2의 다중극렌즈전극에 근접하여 위치하고, 각각의 다중극렌즈는 주집속렌즈의 강도가 당해 다중극렌즈의 강도와 상관관계를 가지며 변화하도록 주집속렌즈에 근접배치된 것을 특징으로하는 음극선관.
  6. 제5항에 있어서, 상기 다중극렌즈는 상기 제1및 제2의 다중극렌즈 전극 (42)(44)의 대면부(62)(72)로 이루어진 것을 특징으로 하는 음극선관.
  7. 제6항에 있어서, 상기 다중극렌즈는 4중극렌즈인것을 특징으로하는 음극선관.
