ABSTRACT:
A field emission display device having thin film diamond cathodes and a method for producing the display device are disclosed. The field emission display device has an insulating layer having circular pattern apertures, and the field emission diamond cathodes formed in the apertures of the insulating layer respectively. The display device is formed by forming an insulating layer on a cathode layer, etching the insulating layer using a photoresist so as to form the apertures in the insulating layer, removing the photoresist from the insulating layer and forming a separation layer on the insulating layer, forming a plurality of thin-film diamond cathodes in the apertures and, at the same time, forming a diamond layer on the separation layer, and removing the separation layer together with the diamond layer from the insulating layer through a lift off process.
