It appears to be a faulty screen. Your iPad should be exchanged for a new one.
Just take it back to the shop if you brogue it from a shop, if online ask for support on getting a new one.
Did it come like that.
My friend bought it from Australia, then I bought from my friend who sent him to the road freight
Well sorry for you
