Paz just appeared in criminal court in Manhattan -- where the D.A. filed 5 misdemeanor charges against de la Huerta ... including two counts of 3rd degree assault, 4th degree criminal possession of a weapon, attempted assault, and harassment.
The judge also granted a temporary restraining order against Paz -- which even prohibits Paz from contacting Samantha on Facebook.
As we first reported, Paz allegedly threw a drinking glass at Samantha and punched her in the face during a party at the Standard Hotel on March 22.
Paz is due back in court on May 19.
UPDATE: Prosecutors told the judge Paz trashed Samantha during her stint in the police station on the night of the incident ... saying, "I'm a REAL actress -- HBO! She's a publicity seeker, a FAKE actress."
