摘要： The present invention aims to form an electron emission film containing an alkali metal compound or the like without causing alkali attack on the metal wiring. An FED display device comprises: an electron source including an electron emission film 13 on the surface thereof; and metal wirings 17, 18 and the like for supplying a signal or the like to the electron source. After forming on the surface of the metal wiring 18 an corrosion resistant film 21 comprising a reactive film or adsorption film with phosphorus, an alkali metal or the like is coated onto or added into the electron emission film 13. The addition of phosphorus is made fewer than the chemical equivalent of the alkali metal salt. Such configuration can improve the electron emission efficiency of the electron source without the metal wiring being corroded by alkali metal or the like.
