Abstract
Provided is a field emission lamp (FEL), which includes a plurality of cathode electrodes formed above a first substrate, an anode electrode formed under a second substrate to face the cathode electrode, a fluorescent layer composed of red, green and blue (RGB) patterns formed alternately on the anode electrode in an oblique direction, and a plurality of emitters formed on the cathode electrodes to correspond to the RGB patterns. According to the present invention, as an FEL having a fast response time is used as a backlight unit, a color breaking phenomenon can be prevented in a color sequential driving method.

A field emission lamp, comprising:
- a first substrate;
- a second substrate;
- a plurality of cathode electrodes formed above the first substrate;
- an anode electrode formed under the second substrate to face the cathode electrodes;
- a fluorescent layer composed of red patterns, green patterns and blue patterns (RGB patterns) formed alternately in an oblique direction;
- and
- a plurality of emitters formed on the cathode electrodes to correspond to the RGB patterns,
- wherein the cathode electrodes, the emitters and the fluorescent layer form at least one unit block,
- further wherein each of the RGB patterns of one of the at least one unit block is continuous, unbroken and has a longest dimension thereof extending in the oblique direction.
