Display device and manufacturing method of display device

A manufacturing method of a display device, comprising:

• providing a display panel having a display area and a non-display area surrounding the display area, wherein the display panel comprises an array substrate and a color film substrate arranged opposite to each other, and the array substrate comprises a gate driving circuit located in the non-display area;
• attaching a first polarizer to the array substrate, and forming a first light shielding layer on one side of the array substrate away from the color film substrate, wherein an orthographic projection of the first light shielding layer on the array substrate is located in the non-display area and at least partially covers the gate driving circuit;
• binding a driving chip on the array substrate to which the first polarizer has been attached, and binding one end of a flexible circuit board on the array substrate and connecting another end of the flexible circuit board to a driving circuit board to form a display module;
• and
• providing a housing and a backlight module, sequentially mounting the backlight module and the display module within the housing, and positioning the color film substrate between the array substrate and the backlight module.
