Abstract
A new light emitting device is disclosed, including a polarizing surface layer, a light emitting layer which emits light at a wavelength, and a light transformation layer disposed between the light emitting layer and the reflective layer, wherein the light emitting layer is disposed between the reflective layer and the polarizing surface layer, and an optical thickness between the light emitting layer and the reflective layer is less than a value of five times of a quarter of the wavelength.
Claims16
A light emitting device, at least comprising:
- a polarizing surface layer;
- a light emitting layer which emits light at a wavelength;
- a reflective layer, wherein the light emitting layer is disposed between the reflective layer and the polarizing surface layer, and an optical thickness between the light emitting layer and the reflective layer is less than a value of five times of a quarter of the wavelength;
- and
- a light transformation layer disposed between the light emitting layer and the reflective layer, wherein the light transformation layer comprises pores or grooves extending into the reflective layer.
