LL Cool J -- Intruder's Busted Face REVEALED In Court

The 56-year-old alleged burglar who got his ass whooped by LL Cool J last week just appeared in court ... finally revealing his bruises from his painful encounter at the rapper's L.A. home.

The transient in question -- a man named Jonathan Kirby -- is still sporting two black eyes ... presumably from the nose-breaking punch LL delivered on the night Kirby broke into his home last week.

During the hearing, Kirby pled "not guilty" to 1st degree burglary with a person present.

As we reported, the L.A. County District Attorney charged Kirby as a 3rd strike offender, which means Kirby now faces life in prison if convicted.
