ABSTRACT:
The present invention provides an array-like flat lighting source, which has an array of field emitter elements. The structure of the array of field emitter elements includes a substrate and a plurality of field emitter elements. The substrate has a plurality of grooves formed thereon and each of the field emitter elements is disposed in one of the grooves. The present field emission lighting source is spacer free, and its upper and lower substrates can be made of a same material to facilitate the maintenance of the vacuum. The array of field emitter elements can have an auxiliary conductive line for repair to guarantee normal operation of the light source if one of electrode lines becomes open.
