Can a Scratch on LCD be repaired

This is probably going to sound insane, but has anyone ever tried something like clear nail polish? To fill in the scratch?

My theory is that if you place a thin glass (an actual aftermarket glass, or a tempered glass) and use a liquid adhesive to stick the thin glass (though the glass should already come with adhesive) the scratches wouldnt be visible anymore. It should work by letting the glue fill the gap and letting the glass keep the gap filled flat with the glue so it keeps the scratches "invisible".

Of course I realize that if your intention is to keep the screen bare, then this answer will not help in anyway. It's just one option to consider. Pls let me know what happens if you decide to try

So bad to hear that but that to remove you have to use some drops of water with tissue paper any other cleaner makes bad on it.

Not likely - Some customers will happily take a discount on the screen repair if you are honest about your mistake - And sometimes it is hardly visible with the glas back on.

But not able to remove it, like others have said

I used feviquick as a paint coat on scratches by use of toothpick sharper side for scratches mede by steel wires (deep enough) and after that screen was same as new while viewing ( satisfaction 95 to 99 %)
