I'd strongly suggest not cleaning the adhesive off the display with alcohol. Use a heat gun or hair dryer as Billinski suggested, even if you leave a little bit of adhesive behind. The same thing happened to me as to Alex in 2021: using IPA to clean the adhesive left around the frame, alcohol went between the glass and the screen. Display is quite cloudy but functions 100%.

Someone (not me) posted a reddit thread in the /mobilerepair sub titled "Alcohol seeped under my IPad's screen" that describes the same issue, alcohol between screen/glass.
