Those black lines and shadows suddenly appeared on my screen on July, and did not disappear after rebooting. I used another screen to test, and there was no black lines there. So definitely, there are something wrong with my screen. It makes me sick when looking at it.
Is it a design deficiency?

Hi GreenMaxLeo,
Thanks for the additional information and letting us know how those steps went.
It sounds like an evaluation of your Mac would be the best next step. Depending on your location, this can be done a few different ways. Reaching out to Contact Apple Support to get specifics on what's available in your region would be best.
Take care.
Thanks, Jeff. My MacOS is Catalina 10.15.7 (19H2).
The issue just suddenly appeared without any liquid splashing or setting change, and resetting SMC and NVRAM didn't seem to solve the problem.
Occasionally, it could revert to a normal screen without black lines maybe after dozens of attempts to open the lid extremely carefully, but once the screen was spun a little bit, it would relapse into a black-lined screen.
I saw some posts said that there's a design problem with the flex gate, where a cable connected to the screen was too short that is likely to break after years of closing and opening of the lid.
I highly suspect it's the same issue with the flex cable as said in those posts. However, my apple care will expire on 10th, Nov, 2020, and I am not able to go to any reachable apple shop to check and repair before that date due to the coronavirus pandemic.
So,
Best Regards.
