There is bleeding/blotch in the LCD after screen replacement

I had my digitizer replaced when it shattered. The lcd wasn't affected as it was a light crack that grew into spider web, however after the replacement, I noticed this small bleeding in the LCD that wasn't there before, so I went and ask the technician about it and he explained it to me that it was normal to have it because of the shattered digitizer. I don't believe him though, but I won't ask him to fix it again for me as I already went back two times first due to the malfunctioning digitizer he first used, second is this, so I'm a bit afraid that the technician will just ruin my iPad. Is there anyway that this can be fixed, or should I get my lcd replaced? PIC
