FIELD EMISSION DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A field emission display device and manufacturing method thereof is provided to improve picture quality characteristics by preventing a crosstalk among R, G and B phosphors. CONSTITUTION: An upper substrate(30) and lower substrate(20) is located oppositely to each other with predetermined distance. A cathode electrode(21) structures are formed on the opposite surface of the lower substrate with stripe shape. An anode electrode(31,310) is formed on the opposite surface of the upper substrate. A black matrixes(32) are formed on the surface of the anode electrode of the upper substrate corresponding to a space between the cathode electrode structures. R, G, and B phosphors(33a,33b,33c) are formed at a space between the black matrixes corresponding to the cathode electrode structures. The black matrixes are bigger than 20um and smaller than distance between the upper and lower substrates
