    摘要: Disclosed are a white LED, which has color reproducibility comparable with that of a cold-cathode tube and improved brightness, and a backlight and a liquid crystal display device comprising the white LED. The white LED comprises at least one light emitting element selected from ultraviolet light emitting diodes, purple light emitting diodes, ultraviolet light emitting lasers, and purple light emitting lasers, and a phosphor layer. The phosphor layer comprises a green phosphor satisfying formula 1, a blue phosphor satisfying formula 2 or 3, and a red phosphor satisfying formula 4 or 5: a trivalent cerium- and terbium-activated rare earth boride phosphor represented by formula 1: M1-x-yCexTbyBO3 wherein M represents at least one element selected from Sc (scandium), Y (yttrium), La (lanthanum), Gd (gadolinium), and Lu (lutetium); and x and y are respective numbers of 0.03
