Why does my iPhone 6 have rainbow colored lines going vertical?

[iMore Question]

It was in my pocket in gym class when I noticed it. The right side of the phone works but not the left side, which is the side that is affected. Therefore I cannot plug in my password to get in my phone. Does anyone know how this can be fixed, and quick? Thanks a lot.

Seems like you may have damaged the screen/digitizer. I'd make an appointment with Genius Bar at an Apple store or authorized dealer near your area.
