Why Does My Screen Look Like This?

Why Does My Screen Look Like This?

My chromebook screen randomly had a random glitch effect on it, I have dropped it a couple times, but not recently (maybe a month ago) anyways after it looking normal after me going to sleep last night, randomly I opened it, and it looked crazy. I tried turning it completely off, and it didn’t help, I signed into different accounts, also didn’t help. What is wrong with it, and how do I fix it?
