Abstract

본 발명의 평면 화상표시장치에 관해 개시한 것으로서 특히 대형의 표시장치에 유리하도록 그 구조가 개량된다. 본 발명은 상,하면에서 서로 직교되게 배열형성되고 전자관통공(50a)이 형성된 절연기판(50)과 배면판(30)사이를 복수의 격벽(60)으로 유지시키고, 격벽과 격벽사이에 복수의 음극선 (33)들을 마련하였는바, 이 음극선(33)은 일정간격으로 마련된 복수의 서포터(32)에 의해 지지된다. 그리고 절연기판(50)과, 전면판(20)사이에는 상기 절연기판(50)의 관통공(50a)에 대응하는 전가 가이드홀(40a)이 형성된 가이드판(40)을 마련하였는 바 이 가이드판(40)은 전면판(20)과 절연기판(50) 사이에 밀착되도록 마련된다.Disclosed is a flat image display device of the present invention, and its structure is improved to be particularly advantageous for large display devices. The present invention maintains a plurality of partition walls 60 between the insulating substrate 50 and the back plate 30, which are arranged to be perpendicular to each other in the upper and lower surfaces and have the electron through holes 50a formed therebetween, and between the partition walls and the partition walls. Cathode rays 33 have been provided, and the cathode rays 33 are supported by a plurality of supporters 32 provided at regular intervals. In addition, a guide plate 40 having a transfer guide hole 40a corresponding to the through hole 50a of the insulation substrate 50 is provided between the insulation substrate 50 and the front plate 20. 40 is provided to be in close contact between the front plate 20 and the insulating substrate 50.
