Narrative:

B767-300 jfk-lax. Flight, approach, landing (runway 25L) and rollout were normal. Captain took control of the aircraft and turned off at taxiway M. We were issued instructions to hold short of runway 25R. I acknowledged to tower and the captain acknowledged to me. After we turned off and as we began to slow from taxi speed to a stop, I went 'heads down' briefly to initiate the after landing checklist flow. When I looked up we were stopped and the only line I saw ahead of us was the runway edge. I said 'we're past the hold line' to the captain as tower cleared an aircraft for takeoff on runway 25R. Captain said 'call the tower,' which I immediately did. Tower canceled his takeoff clearance and when he acknowledged we were cleared across runway 25R. We were told later he had not started his takeoff roll. Factor: runways at lax are very close together and even an angled taxiway the hold line comes fast -- in a large aircraft you may not even feel your tail is clear of the runway. Lesson: even 5 seconds heads down may be too long! Supplemental information from acn 428213: ground control advised us to call the tower on the phone, which we did.
