Is the LCD on my iPhone 5c broken?

Is the LCD on my iPhone 5c broken?

Its probably your LCD/ Digitizer. The digitizer is what makes the touch screen work, and the LCD is just the display, in most cases they install a new screen LCD and digitizer for around 100 dollers, but you can do it yourself for around 35 by ordering a kit on Ebay/Amazon

I dropped it and now the screen in unresponsive and has white vertical lines running down it on the right hand side. Is this because of the LCD? If i get it replaced will the phone otherwise be fixed?
