FIELD EMISSION TYPE BACK LIGHT UNIT AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE BACK LIGHT UNIT

摘要

PURPOSE: An LCD device having front emission type backlight unit and a backlight unit are provided to reduce visibility of shade part of the backlight unit, thereby improving the quality of an image. CONSTITUTION: A FED(Field Emission Display)(110) has a light emitting parts(110a) and darkness part(110b). The darkness part exists between the light emitting parts. An optical film(120) is arranged on the FED. The optical film has at least one function among a diffusing function and a refracting function. By an optical film, the emitted light of the FED is dispersed or refracted. Therefore, the visibility of a shade part is demoralized.
