An electron emission display including a first substrate having at least one electron emission device and a second substrate opposite the first substrate. The second substrate is formed with an effective region and a non-effective region. The effective region includes a fluorescent layer for emitting light by collision with electrons emitted from the electron emission device. The non-effective region includes a region in which a light-shielding layer has a transparent conductive layer and a metal layer. The transparent conductive layer is formed in the effective region where the fluorescent layer is absent. The second substrate improves the brightness of light emitted from the fluorescent layer and prevents a power supply layer, to which a high voltage is applied, from being damaged, because the transparent conductive layer is not formed under the effective region.

Electron emission display

An electron emission display comprising an electron collector or metal member is provided. The electron emission display comprises an electron emission substrate comprising at least one electron emission device and an image forming substrate comprising at least one emission region and at least one non-emission region. Images are formed in the emission regions by the collision of electrons emitted from the electron emission devices with the emission regions. The image forming substrate further comprises a metal layer positioned on at least the emission regions, and at least one electron collector positioned in the non-emission region. The electron collector may comprise first and second ends, wherein the first end is attached to the image forming substrate and the second end faces the electron emission substrate. The electron collector stabilizes the metal layer and fluorescent layers, thereby reducing arc and maintaining uniform brightness by re-directing scattered electrons toward the fluorescent layers.

Electron emission display device with electron collector or metal member

An electron emission display including an electron emission substrate having at least one electron emission device formed thereon and an image forming substrate spaced apart from the electron emission substrate. The image forming substrate includes an effective region where electrons emitted from the electron emission device collide with the effective region to form images and a black region surrounding the effective region. The effective region includes a fluorescent layer formed in an arbitrary pattern and a metal layer formed on the fluorescent layer. The metal layer has a structure extending onto at least a portion of the black region.

An electron emission device and an electron emission display, in which a driving electrode is protected from being damaged when an overcurrent instantly flows therein. The electron emission device includes a first driving electrode disposed on a plate, a second driving electrode disposed on the plate and insulated from the first driving electrode, and an electron emission portion connected to the first driving electrode. The electron emission portion emits electrons in response to a voltage difference between the first driving electrode and the second driving electrode. The second driving electrode has at least two separate portions, and the at least two separate portions are coupled to each other by at least one band having a predetermined width adapted to electrically isolate at least one portion of the second driving electrode from the electron emission portion when an overcurrent is applied between the second driving electrode and the electron emission portion.
