Embodiment Construction

[0042] Hereinafter, a field emission display including a mesh grid and a manufacturing method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

[0043] Figure 4 is a schematic cross-sectional view of a field emission display according to an embodiment of the present invention.

[0044] refer to Figure 4 , The field emission display including this embodiment has a connection structure of a front substrate 41 and a rear substrate 42, which are separated from each other by a predetermined distance, so that a vacuum space is formed between the two substrates. The spacer 43 is provided for maintaining the space between the front base 41 and the rear base 42 . The cathode 55 is formed inside the rear substrate 42 . The insulator 45 is formed on the cathode 55 . The insulator 45 has holes therein. Emitters 46 serving as electron emission sources are exposed outside through these holes.

[0045]The gate 47 is f...

Abstract

Provided are a field emission display and a method of manufacturing the same. A flat panel display device of the present invention comprises: a first substrate; an electron emission assembly being formed on said first substrate; a second substrate being provided at a predetermined distance from said first substrate, said first and second substrates forming a vacuum space; and an illumination assembly being formed on said second substrate, said illumination assembly being illuminated by electrons emitted from said electron emission assembly; a mesh grid provided above said electron emission assembly.

Description

[0001] This application claims priority to Korean Patent Application No. 2003-3982 filed on Jan. 21, 2003 and Korean Patent Application No. 2003-44534 filed on Jul. 2, 2003 in the Korean Intellectual Property Office, which are hereby disclosed together as a reference. technical field [0002] The present invention relates to a field emission display and its manufacturing method, in particular to a field emission display including a mesh grid and a focusing electrode and its manufacturing method. Background technique [0003] A field emission display (FED) is a device consisting of a front substrate and a rear substrate forming a vacuum chamber. The front substrate includes an anode and phosphors on its inner side. The rear substrate includes the cathode and the emitter on its inner side. Electrons emitted by the emitter are directed at the anode and excite the phosphor, thereby emitting a predetermined light. Field emission displays can be used in car dashboards. [0004...
