Abstract
A display device includes a backside and a front-side substrates facing each other with a vacuum space therebetween; and a plurality of electron emission sites provided on the backside substrate. Each electron emission sites includes a bottom electrode formed on a surface of the backside substrate proximate to the vacuum space, an insulator layer formed over the bottom electrode, and a top electrode formed on the insulator layer and arranged individually apart from each other and facing the vacuum space. The display device also includes a plurality of bus electrodes for electrically connecting the neighboring top electrodes; and insulating protective films each provided between the bus electrode and the insulator layer and between the bus electrode and the backside substrate.
