By　investigating　the　field　emission　characteristics　of　carbon　nanotubes　(CNTs)　films　fabricated　by　multi-step　screen-printed　process,　it　is　found　that　turn-on　electric　field　could　be　enhanced　by　multi-step　printing　process,　especially　two-step　printing　film　the　best　field　emission　characteristics.　Microstructure　characterization　shows　matching　structure　between　interfaces　of　films　is　created　after　the　second　printing,　and　contact　area　between　printing　film　and　substrate　is　increased.　Electrical　conductivity　and　the　probability　of　forming　ohmic　contact　as　well　as　the　field　enhanced　factor　increase　resulting　from　the　special　structure.　Furthermore,　test　of　CNTs　films　with　different　content　concurrently　shows　that　emission　current　and　luminant　uniformity　of　CNTs　films　are　prominently　enhanced　by　two-step　printing　process.
