Brownish specks appear consistently on my screen

After replacing the battery on my iPhone 5, two small patches of brownish specks appeared on my screen, they look sort of like cracker crumbs underneath the screen. During the operation I accidentally started to peel the display assembly apart (the screen and the LCD) also I had to clip in the LCD ribbons a few times. Would the specks most likely be from damage to the ribbons or the LCD itself?

Also the right side of the screen is raised ever so slightly and won't clip in. Would this be from the clip breaking? Thanks in advance, sorry for the long post.

Edit: These are the dots

And the possible broken clip
