1. A display device, comprising:
a display panel comprising:
a thin film transistor (TFT) array substrate;
a color filter (CF) substrate opposite to the TFT array substrate;
a lower polarizer on a side of the TFT array substrate away from the CF substrate, the lower polarizer defining a first through hole;
an upper polarizer on a side of the CF substrate away from the TFT array substrate, the upper polarizer defining a second through hole, wherein the display panel defines a display area configured for displaying images, a light transmission area surrounded by the display area, and a light shielding area between the display area and the light transmission area, the light shielding area surrounds the light transmission area, the first through hole and the second through hole are aligned with the light transmission area along a thickness direction of the display panel; and
a first light shielding material on a side of the TFT array substrate away from the CF substrate, wherein at least a part of the first light shielding material is in the first through hole, the first light shielding material is aligned with the light shielding area and surrounds the light transmission area, the first light shielding material is configured for absorbing light from a side of the lower polarizer away from the TFT array substrate toward the light transmission area;
a backlight module, wherein the display panel comprises a display surface, the backlight module is on a side of the display panel away from the display surface, the backlight module defines a mounting hole aligned with the first through hole; and
a camera module in the mounting hole;
wherein the backlight module comprises a back plate for carrying optical components of the backlight module, and the back plate comprises a flat plate-shaped bottom plate and a frame connected to the bottom plate, the frame is shaped to define an inner wall of the mounting hole;
wherein the display device further comprises a first light shielding portion, the first light shielding portion is in direct contact with both the display panel and the frame to fix the display panel and the frame; the first light shielding portion is aligned with the light shielding area and surrounds the light transmission area;
wherein the first light shielding material is between the TFT array substrate and the lower polarizer;
the display device further comprises a second light shielding portion, the second light shielding portion is between the lower polarizer and the frame, wherein
the second light shielding portion is in the light shielding area and surrounds the light transmission area; and
the second light shielding portion extends beyond the frame in a direction away from the light transmission area of the frame.
