Abstract

Provided are a light emitting device using electron emission with a low driving voltage and high luminous efficiency, and a flat display apparatus using the light emitting device. In addition, a light emitting device using electron emission in which with a nano-sized gap can be formed with repeatability and have reliability is provided. The light emitting device includes: a plurality of PN junctions (34), each including a depletion layer having a predetermined thickness; an anode electrode (12) facing the depletion layer and separated from the depletion layer by a predetermined distance; and a phosphor layer (13) formed on a surface of the anode electrode. The flat display apparatus includes the light emitting device.

Description

[0001] Cross references to patent applications [0002] This application claims the benefit of Korean Patent Application No. 10-2005-0095487 filed with the Korean Intellectual Property Office on Oct. 11, 2005, which is incorporated herein by reference. technical field [0003] Embodiments of the present invention relate to a light emitting device using electron emission and a flat panel display device using the light emitting device, and more particularly to a light emitting device using electron emission having a low driving voltage and high luminous efficiency, and a light emitting device using the light emitting device Flat panel display device. Background technique [0004] A plasma display panel (PDP), which is a flat panel display device, uses electric discharge to form images. DPD is widely used due to its outstanding display characteristics such as high brightness and large viewing angle. PDPs can be classified into a facing discharge type or a surface discharge ty...
