Abstract
The invention provides a manufacturing method of a quantum dot glue, a quantum dot glue and a quantum dot polarizer. In the manufacturing method, a polyvinyl alcohol glue is added with water-soluble quantum dot materials, and an alkaline solution is used to adjust its pH value to be above 7, so that a quantum dot glue is obtained, the manufacturing process is simple and the obtained quantum dot glue can be used for fabricating a quantum dot polarizer. The quantum dot polarizer is provided with a quantum dot glue layer formed by coating the quantum dot glue, since the quantum dot glue itself is alkaline, an alkali treatment process applied to a bonded layer is eliminated and thus can be directly coated, so that the manufacturing process is simplified. Moreover, since it is added with quantum dot materials, color gamut and display quality of display device can be improved.
