Abstract:
The present invention relates to a light emitting device, comprising: a LED die (10) having a first surface (12), a second surface (14) and at least one side facet (16) connecting the first and the second surface (12, 14). Further, the LED die comprises a light polarizing layer (20), a light blocking layer (30), and a light reflecting layer (40). The light polarizing layer (20) is arranged on the first surface (12), the light blocking layer (30) is arranged on the at least one side facet (16), and the light reflecting layer (40) is arranged on the second surface (14) of the LED die.
