Screen Blurry and Have Spiders Pattern

In 2012, my Macbook was fall from the closet around 1 meters high. Everything was fine. The laptop keep running although I hear some crack in DVD player. And get small dent in the corner of screen but overall works fine.

In 2016, I was stupid cleaning the screen with alcohol 70%. Back then I did not know that the alcohol is abrasive for lcd screen. The ant come into the back of the glass and crawling there. The alcohol incident left my screen have blurry bottom.

Now in 2020, the LCD screen have block blurry spiders pattern in the Middle of the monitor.

Would anyone advise how to repair it?
