Abstract
A method of manufacturing an upper panel of a field emission type backlight unit. The method includes: sequentially forming an anode electrode and a phosphor layer on a substrate; forming a metal reflection film on the phosphor layer; and annealing a surface of the metal reflection film. The method can increase brightness of an image, can prevent occurrence of an electric arc when a high driving voltage is applied to the backlight unit, and allows removal of residues produced when manufacturing the backlight unit.
