An electron emission source and a field emission display using the electron emission source are provided to increase an aspect ratio and electric field by using a DLC(Diamond-Like Carbon) film layer. An electron emission source is comprised of a substrate and a film structure deposited on the substrate. The film structure is made of a DLC film layer(31). The film structure of the DLC film layer is arranged on the substrate to configure a petal shape. A lateral height of the film structure is from 0.5 to 4.0mum. The substrate is made of a semiconductor material, a metal material, an insulation material, or a glass material. The film structure is a curved film structure, a long-strip film structure, or a combination thereof. A thickness of the film structure is 0.005 to 0.1mum.
