Description

technical field

[0001] The present invention relates to a field emission element for a background light, in particular to an application for a background light in which the shape of the fluorescent surface of the fluorescent body formed by the field emission element using carbon nanotubes as an electron emission source is a protruding surface, thereby increasing the coating area of ​​the fluorescent body to the emitting element. Background technique

[0002] Recently, as various display devices are developed, the importance of light sources is also being increased. These light sources use various methods such as heating a filament, using gas discharge, and emitting light from a phosphor. These light sources can only be used as simple lighting equipment, but they can also be used as display backlights such as LCDs in the form of surface light sources.

[0003] The backlight of this kind of LCD mainly uses a fluorescent lamp (Flourescent Lamp: FL) that can improve a very hig...
