After seven seasons of playing teenage vampire Jessica Hamby on HBO’s “True Blood,” Deborah Ann Woll is relishing the opportunity to portray a grown-up woman in the new Netflix drama “Marvel’s Daredevil.”

The role of Karen Page — the secretary and future love interest of blind lawyer/vigilante Matt Murdock (aka Daredevil) — holds a personal connection for Woll as well. Her boyfriend of seven years, comedian EJ Scott, has the rare genetic disease choroideremia, which is causing him to lose his eyesight.

“It was intensely interesting to me to have a visually impaired character on television. I think they’re under-represented for sure,” Woll, 30, tells The Post.

“We’re not meant to pity [Daredevil] and we’re not ignoring the fact that he’s blind either. It’s a part of his personality but it doesn’t define him. He’s very capable. As the partner to someone who is legally blind … I am invested in seeing that story told in a compassionate but realistic way.”

“Daredevil” (premiering Friday on Netflix) takes place in modern-day Hell’s Kitchen in the aftermath of a catastrophic incident that has left the West Side a picture of ’70s-era crime and seediness.

The series filmed in New York City, which besides allowing Woll — who was born and raised in Brooklyn — the opportunity to spend time with family and friends, added the authenticity of shooting on real city streets.

“On my way to work I got yelled at by a cab driver so that reminded me that that’s something Karen would have dealt with as well,” she says. “We must have found every remaining dark alley in New York City to shoot in.”

The Page character takes on a much bigger role in the Netflix series than she did in the 2003 film (as portrayed by Ellen Pompeo). After being the victim of a crime, she goes to work for Murdock (Charlie Cox) and his ambulance-chasing partner Foggy Nelson (Elden Henson) as a law secretary at their fledgling firm.

“Even if [Karen] doesn’t have the training, she has the smarts and the wits to help a lot more than the average secretary would be expected to help,” Woll says. “I like that part of her that says, ‘I don’t care if I’m not the lawyer, I’m going to go out and figure this out and you guys aren’t going far enough.’ She won’t let them rest on their laurels.”

Though Page was Daredevil’s longest-running love interest in the comic books — and there are hints of chemistry in the pilot — Woll is mum on whether a romance will develop in the 13-episode first season.

“They need each other and they take care of each other in a way that is sort of deeper than romance,” she says. “That’s not to say that romance and friendship won’t bloom between them all, but in a way it’s more important that they are there for each other as family.”
