A backlight module and a liquid crystal display are disclosed. In the backlight module having a reflector base, a phosphor layer is disposed on the reflector base, and a plurality of blue light emitting diode (LEDs) are disposed above the reflector base and the phosphor layer for emitting a first light beam.
