Flat panel display device

A display device comprising:

• a rear substrate provided with a plurality of cold cathode elements for emitting electrons;
• a display substrate including a light-transmissive substrate disposed to face said rear substrate;
• an electrically conductive sheet provided on a surface of said light-transmissive substrate facing toward said rear substrate, and
• a metal back adapted to be supplied with an anode voltage for leading said electrons from said plurality of cold cathode elements toward said electrically conductive sheet, said metal back being provided on a side of said electrically conductive sheet facing toward said rear substrate;
• wherein said electrically conductive sheet is perforated with a plurality of holes each corresponding to one of said plurality of cold cathode elements, each of said plurality of holes has a phosphor disposed therewithin for generating light when excited by said electrons emitted from said plurality of cold cathode elements, and a thickness of said electrically conductive sheet being greater than a thickness of said phosphors disposed within said plurality of holes;
• and
• wherein said display substrate further includes an adherent layer for affixing said electrically conductive sheet to said light-transmissive substrate.
