After this step, you will need a torx bit smaller than a T-4. The circled display assembly can be replaced as a unit if you wish. In that case, this is the final step.
Some kits do not have a bit small enough bit for these screws. If you do not have the proper bit, you should either buy one or simply replace the whole screen and digitizer assembly.
The silver plate may be covering up the screws. If you do not see them, slide it to the other end of the assembly.
The entire back of the screen is glued to the assembly, making it more difficult to remove. Since this part is already broken, don't be afraid to force it out.
