Abstract
A polarizing light emitting plate includes a polarizing layer having a polarizing axis substantially parallel to a first direction, a quantum rod layer including quantum rods aligned in the first direction, and an attachment layer between the polarizing layer and the quantum rod layer and comprising an adhesive material.
Claims25
A polarizing light emitting plate comprising:
- a polarizing layer having a polarizing axis substantially parallel to a first direction;
- a quantum rod layer comprising quantum rods aligned in the first direction;
- and
- an attachment layer between the polarizing layer and the quantum rod layer,
