摘要：In an electron emission device, the surface roughness of a substrate with driving

electrodes and an insulating layer is optimized. The electron emission device includesfirst and second substrates facing each other with a predetermined distance

therebetween. An electron emission unit is formed on a surface of the first substratefacing the second substrate, and includes electron emission regions, a plurality of drivingelectrodes, and an insulating layer for insulating the driving electrodes from each other.A light emission unit is formed on a surface of the second substrate facing the firstsubstrate, and includes phosphor layers and an anode electrode. The first substratesatisfies the following condition: 0.5 nm≦Ra≦1.8 nm, where Ra indicates the averageroughness of the surface of the first substrate facing the second substrate.
