Abstract
The present invention relates to a polarized light emitting diode (LED) device and the method for manufacturing the same, in which the LED device comprises: a base, a light emitting diode (LED) chip, a polarizing waveguide and a packaging material. In an exemplary embodiment, the LED chip is disposed on the base and is configured with a first light-emitting surface for outputting light therefrom; and the waveguide, being comprised of a polarization layer, a reflection layer, a conversion layer and a light transmitting layer, is disposed at the optical path of the light emitted from the LED chip; and the packaging material is used for packaging the waveguide, the LED chip and the base into a package.
