Weird pixel error?

Hi everyone

long ago I took out my Casio fx-85ES , and got surprised with this weird pixel error :

This one shows even up while the calculator is powered off .

So I tried fixing by removing the glass from the display , which went wrong (I’m a newbie in tech) because I heard something splitter , after turning it on I managed to do this :

The middle row is ripped unfortunately , so I got completely confused .

Thanks for reading / answering !! I’d be glad if someone might help me !

I really don't think these displays are meant to be taken apart at all.
