IPhone 5s screen cracked. Full phone replacement or just LCD and glass?

So I smashed my whole iPhone 5s. Not only is the glass cracked, but the LCD doesn't display any images. It lights up and when touched, it shows cracks in the LCD panel. My question is should I replace my whole phone? Or replace the glass and LCD. I don't want to end up paying money for replacement parts if it isn't going to fix it.
Summary: My glass and screen are cracked and the LCD doesn't display images- it lights up when turned on, but doesn't show anything. Should I replace the parts or the whole phone?

Just the glass
