Field emitting flat light source and method for making the same

A method for making the field emission flat light source comprising the steps of:

• forming an anode member by:
• preparing an anode substrate;
• forming a metal reflective layer and an anode electrode above said anode substrate using vapor plating, electroplating or sputtering method, wherein said anode electrode is a transparent or opaque substantially single anode electrode, wherein, when said substantially single anode electrode is opaque, it is formed from Cr or Mo materials and is sandwiched between said anode substrate and said metal reflective layer, and wherein, when said substantially single anode electrode is transparent, it is formed from an ITO material;
• forming an emitting layer above the metal reflective layer using coating or magnetron sputtering method, wherein said transparent substantially single anode electrode is sandwiched between the anode substrate and said metal reflective layer or between said metal reflective layer and said emitting layer;
• forming a cathode member by:
• preparing an electron emitter on a cathode substrate using spraying or direct growth method;
• and
• assembling the field emission flat light source by:
• placing the anode member on a horizontal operation table,
• subsequently, securing an isolater on a periphery of the anode member,
• subsequently, securing the cathode member on the isolater in a parallel relationship with said anode member,
• leading out the electrodes;
• subsequently, pressing, securing and sealing the light-transmittable panel to the isolater in spaced apart relationship to said anode member, and
• subsequently, sealing and vacuum pumping the assembled field emission flat light source through an exhaust pipe.
