My iphone 5 was dropped, if I replace the screen, will this fix my issue?

I dropped my iphone 5 and now it has colourful lines on the left side of the screen. If I replace the screen will it it fix it? If not, how will I fix it?

Added (1). The screen is all so cracked a little from one side too another around the top

Change the screen and its fixed

As long as there's no damage to the logic board a new screen should fix it. The repairer would check this anyway
