Patent ID: 8872421

Claim:
A white LED for a backlight of a liquid crystal display device, comprising at least one light emitting element selected from ultraviolet light emitting diodes, violet light emitting diodes, ultraviolet light emitting lasers and violet light emitting lasers, and a phosphor layer, wherein an emission spectrum of the white LED includes: a first emission peak group comprising at least one emission peak having a maximum intensity in a range of 430 to 470 nm; a second emission peak group having at least one line emission peak having a maximum intensity in a range of 470 to 560 nm; and a third emission peak group having at least one line emission peak having a maximum intensity in a range of 600 to 650 nm, wherein, when maximum intensity P1 of the first emission peak group is determined to be 1, maximum intensity P2 of the second emission peak group is 3≦P2≦5; and maximum intensity P3 of the third emission peak group is 1≦P3≦5.
