The first compensation layer 228 or the second compensation layer 232 enables the surface of the under-screen module 230 away from the display screen 210 and the second surface 222 to be flush, so as to reduce the problem that the under-screen module 230 and the protective layer 220 have imprint marks on the display screen 210 due to uneven stress. The compensation shielding colloid 250 is arranged in the gap formed between the first shielding colloid layer 240 and the second shielding colloid layer 226, so that the compensation shielding colloid 250, the first shielding colloid layer 240 and the second shielding colloid layer 226 are matched into a whole, the problem of light leakage of the display screen assembly is avoided, and the display effect of the display screen assembly is ensured.
