Abstract
An exemplary field emission cathode includes an electrically conductive layer and an electron-emitting member formed thereon. The electron-emitting member includes an electron-emitting material configured for emitting electrons and a getter material configured for collecting outgassed materials. An exemplary planar light source includes an anode and a cathode spaced apart from the anode. The anode includes a first electrically conductive layer and a fluorescent layer formed on an inner surface of the first electrically conductive layer. The cathode includes a second electrically conductive layer and an electron-emitting member formed on an inner surface of the second electrically conductive layer which faces toward the fluorescent layer. The electron-emitting member includes an electron-emitting material and a getter material.
