Abstract
A flat panel display device capable of reducing charging of phosphors and disposing spacers easily and accurately. The flat panel display device has a rear substrate including an insulating substrate provided with many cold cathode elements for emitting electrons, a display substrate including a light-transmissive substrate disposed to face the rear substrate, and phosphors disposed on the light-transmissive substrate for generating light when excited by electron beams from the cold cathode elements, and a peripheral frame member. Provided on the light-transmissive substrate is a metal sheet perforated with plural fine holes arranged in a matrix configuration and having the phosphors disposed therewithin to form a light-emissive region.
