LCD broken while trying to repair screen?

I have a tablet that was dropped onto the floor and the screen cracked. Originally it appeared only the digitizer was broken and the LCD was fine because I was still able to turn it on and navigate the device using the cracked digitizer.

So I bought a digitizer online and tried to replace it, but when I assembled everything, I saw a white background with a bunch of lines and some dark areas on the side. So was the LCD damaged during the repair process?

I did notice that if I pressed down on the digtizier (not fully glued in yet), I saw a vague image of an icon but still had some fuzziness to it. So am I suppose to be able to see something coherent if the digitizer is not glued tightly to the LCD or does some sort of pressure need to be applied to really see something?
