The first substrate 101 includes a pixel electrode (not shown in the figure) and a first driving layer 1011. The second substrate 102 includes a common electrode (not shown in the figure). The voltage applied to the liquid crystal layer 103 is controlled by the first driving layer 1011 to deflect the liquid crystal molecules so that the light emitted from the backlight module 20 passes through the liquid crystal layer 103 and is emitted from the color resistance portion 1021 to varying degrees, thereby achieving normal display of the display panel 10.

[0056] It can be understood that, in this embodiment, a first light-emitting device is arranged corresponding to a color resistance portion, and the orthographic projection of the second light-emitting device on the display panel does not overlap with the plurality of color resistance portions.

[0060] It should be noted that the light-shielding wall 203 and the second polarizer 32 can be arranged at intervals, and the light-shielding wall 203 and the second polarizer 32 can also be in contact with each other. The light-shielding wall 203 and the light source assembly 202 can be arranged at intervals, and the light-shielding wall 203 and the light source assembly 202 can also be in contact with each other.
