Abstract
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. An optical film is disposed above the reflector base, the phosphor layer and the blue LEDs for allowing P-polarized light of the first light beam to pass therethrough and reflecting S-polarized light of the first light beam to the phosphor layer so as to excite the phosphor layer to generate a second light beam of which the wavelengths are different from those of the first light beam. After being reflected to the optical film by the reflector base, the second light beam transmits through the optical film, and mixes with the first light beam to generate white light.
