An electron emission source, a composition for preparing an electron emission source, a method for preparing the electron emission source and an electron emission device comprising the electron emission source

摘要

The present invention is a silicon-based material having a carbon-based material, and the following formula (1), a silicon-based material having the formula (2) and the electron emission source, a composition for forming an electron emission source, manufacturing method and the electron emission source of the electron emission source including the cured and heat treated one or more results of the silicon-based material having the general formula (3) relates to an electron-emitting device comprising: ; & Formula 1 & ; & Formula 2 & ; & Formula 3 & ; of the above formula, R ₁ to R ₂₂ , description of m and n shall refer to the detailed description of the invention. Electronic emission source including the cured and heat-treated product of a silicon-based material, as described above, it has excellent adhesion to the substrate, the reliability of the electron-emitting device having the same can be improved.
