A few cables and hefty display hinge screws hold the display assembly in place, but not for long.

The Retina display LCD is situated in the display assembly, and it's not going anywhere. Chances are if anything related to the display goes bad, you'll be replacing the whole kit'n'caboodle.

Don't forget that the display assembly also includes the FaceTime Camera, WiFi antennas, and Bluetooth antennas.
