Do I just need the glass repaired or more?

So when looking at my iPad it looks really bad! The screen has a lot of cracks and even some holes on the sides where glass fell off and I can see inside. There are holes around the home bottom as well which makes it hard to press but believe it or not it still works. When the screen comes on it looks great. In the dark you can’t even tell there are cracks. BUT the touch screen has stopped working. I need to type in a password to get in and since the touch screen doesn’t work I can’t get In. I have had this since before my son was born and I have baby pictures on there I want to access. I lost my phone when he was 4 months old and lost most of his new born pics so I would really like to access what is on my iPad. But I’m scared of the cost to fix it… will replaceing the glass make the touch screen work or will it need more? Could it be lcd?
