Iphone 4 LSD screen is Damaged. What should I do?

The glass on my Iphone is fine as far as I'm concerned, but the screen underneath (I presume) is damaged and there's a blur of colors. I can still see half of the screen, but the left side is dead.

What should I do?

Try fixing it on my own
Pay upward of 90$
or some other method I'm not fimilar with?

Here is a rough image of what it sort of looks like

You can order a replacement screen and iphone tools online,
and search some videos in YouTube to learn how to replace screen by yourself.
It is not difficult. And will save much money too.

The screen damges will waste your money and time,
you'd better protect your screen well by the newest Premium Tempered glass screen protector:
