Earlier in the day, they informed the judge they were unable to reach a unanimous decision on any of three counts against the 79-year-old comedian.
That was apparently not enough for the judge, who sent them back to the jury room and denied a defense request for a mistrial in the case. The panel was sent home at 9 p.m.
Deliberations are scheduled to begin Friday at 9 a.m
Victoria Valentino, one of Cosby's many accusers, was at the courthouse when the deadlock was revealed.
"I just felt dejected," she said. "I just felt, 'My gosh, if they just can't come to some sort of resolution by the end of the day, I just don't know.'"
Another Cosby accuser, Lili Bernard, got into a heated and passionate exchange with supporters of the disgraced comedian.
Cosby spokesman Andrew Wyatt spoke outside the courthouse Thursday.
"He just wants to say again to these jurors, 'Thank you. Keep working. Keep looking at the facts. Keep deliberating.' Hopefully, we get out of here as we came in, as a not guilty, innocent man," he said.
The jury consists of seven men and five women, including two jurors who are African-American.
Cosby has denied all allegations against him.
