To the topic, try rubbing it with some cleaning agent that are for LCD scratches, if the scratch is too deep buffing it might help.
@barbarian thanks bro followed your advise and 80% scratch is gone
thanks for appreciation see u were woorried about ur old lcd and u knew what happened to it . Now think about me what were my feelings when i saw scratch on my core i5 laptop and i rarely used it !!! i never understood how that scratch occurred still a mystery
