Abstract
A manufacturing method of an array substrate includes the steps of providing a base plate and forming a thin-film transistor (TFT) layer on the base plate; forming a quantum dot layer on the TFT layer; and forming a protective filter layer on the quantum dot layer to provide protection to the quantum dot layer. The protective filter layer also provides an effect of light filtering in order to prevent ultraviolet light or blue light from transmitting therethrough.
