Abstract

본 발명은 전계방출 표시소자의 주공간의 진공을 용이하게 실시하기 위하여 하부기판의 배면에 반구형의 내부를 갖는 보조용기를 부착시키고, 상기 보조용기를 통해 주공간과 보조용기 내부의 공기를 배출시킴으로써, 전계방출 표시소자의 내부를 용이하게 고진공으로 만들수 있으며, 보조용기내에 보조스페이서를 설치할 필요가 없는 전계방출 표시소자를 제공한다.The present invention relates to a field emission display device in which an auxiliary container having a hemispherical inner surface is attached to the rear surface of a lower substrate to easily perform a vacuum between the main surfaces of the field emission display device and air is discharged from the main space and the auxiliary container through the auxiliary container, There is provided a field emission display device which can easily make the inside of the field emission display element highly vacuum and does not need to provide auxiliary spacers in the auxiliary vessel.
