Abstract

See full text

The invention provides the following advantages: the present invention provides a quantum dot polarizer and manufacturing method thereof. The quantum dot polarizer comprises a first protective layer and a second protective layer, and the first protective layer or the second protective layer being a complex film comprising quantum dots. As such, without increasing the thickness of display, the invention can improve color spectrum and transmittance, and is applicable to ultra-thin display devices at low cost. The manufacturing method adds the quantum dots to the cotton glue for forming protective layers by extension or coating process to obtain quantum dot protective layer used for quantum dot polarizer. As such, the invention can avoid humidity and oxygen affecting the quantum dots and reduce cost by eliminating manufacturing independent quantum dot element separately.
