How to fix Blurry Top Screen / Blurry 3D Image?

I recently replaced the top screen of my 3DS XL with a brand new screen. Upon putting everything back together and turning the device on, I noticed that the 3D image is very blurry. I tested the 3d screen with different games and it's the same thing each time. I'd like to note that I confirmed this by showing it to different people, just to make sure it's not my eyesight that's screwed up. I've done as much research as I could, and can't seem to find a fix for it.

I've already tried cleaning the screen and even factory resetting the device. Any ideas on what I could do to fix this? Thanks in advance.
