Lcd half dead after digitizer replacement, can someone help me?

Hello everybody!

I just tried to fix my iPad mini after my father broke the digitizer.

So....where do I start??

• First time I do this kind of operation, purchased all the items from the iFixit store in EU besides the digitizer which was not available.
• Removed the broken digitizer (that was messy...glass shattered everywhere!)
• Removed the lcd and shield plate
• Disconnected broken digitizer, lcd and battery
• Cleaned up everything
• Connected the new digitizer, lcd and battery
• Tested the iPad to see if everything was working
• PROBLEM!

There is no backlight but you can see the icons on the lcd, the problem is that the left half of the screen is dead!

I tried to disconnect and re-connect the lcd again but nothing changed, have I damaged something while I was removing the lcd??

Please find attached some photos of the lcd
