Abstract:
In an electron-emitting device having a pair of electric conductors disposed on a substrate in opposed relationship with each other, and a pair of piled films composed chiefly of carbon and connected to the pair of electric conductors and disposed with a gap interposed therebetween, the piled films contain therein one or more kinds of elements selected from the group of lithium, potassium, sodium, calcium, strontium and barium within the range of 1 mol % to 5 mol % in terms of the percentage to carbon.
