Abstract
The present disclosure relates to a light-emitting diode (LED), including: a grating layer; and a light reflecting layer, wherein a light-emitting component is disposed between the grating layer and the light reflecting layer; and wherein the grating layer is configured to let linearly polarized light perpendicular to a grating direction of the grating layer in light emitted from the light-emitting component transmit through the grating layer, and reflect linearly polarized light parallel to the grating direction of the grating layer in the light emitted from the light-emitting component.
