PURPOSE: A fluorescent indication panel is provided to enable fine patterns by arranging a grid in a lattice configuration for controlling and lighting electrons. CONSTITUTION: A first grid(50) and a second grid(52) are arranged between an anode(40) and a cathode(30) to intersect with each other with a predetermined distance. The first and the second grids(50,52) diffuse thermal electrons emitted from the cathode(30) by acceleration or interrupt the same. The first and the second grids(50,52) are applied with electric power through a number of lead lines(60) provided to the rear panel(22). The first and the second grids(50,52) can be modified to have smaller dimensions such as diameter of a line so that fine pixel may be obtained.
