ABSTRACT:
In an electron beam generation apparatus for a flat cathode ray tube, line cathodes are stretched in an arc shaped form and held by plural cathode position defining members. The cathode position defining members are disposed along the line cathode in a forward convex arc which protrudes most at its center and less towards its respective ends. An electron beam take-out electrode is placed at a in front side of the line cathode and a back electrode is placed at a back side of said line cathode, the electron beam take-out electrode and back electrode also being arc shaped.
