Did I broke touchscreen or touchscreen and LCD?
Modern touchscreens consist of two parts:


The digitizer: This is transparent and detects the touch events.
The LCD: This is the screen and its kinda silver.


The digitizer and LCD are glued and are difficult to separate cleanly. It appears that you've removed a chunk of the LCD as well. The LCD and the digitizer are also sold as a single unit, glued together, so that they are easier to assemble.
