Narrative:

The first officer landed on runway 24R in lax. I took control of the aircraft on the runway; and exited onto taxiway aa. Tower told us to hold short of 24L. I saw the bars that I thought were the runway clear lines for 24R; just in front of me. I continued forward; focused on a faded line that I somehow mistook for the hold short line. The first officer said for me to stop. I then noticed the red stop lights. I didn't jam on the brakes; which I should have; as I went past the hold short line. I asked him to tell the tower that I was past the hold short line. The tower had cleared [another] aircraft for takeoff around the same time. There was a slight delay for the tower to tell the aircraft to reject the takeoff. Even with that; the aircraft wasn't very far down the runway. I believe they may have pulled off at taxiway whiskey. After that; we were cleared to taxi across runway 24L and turn left onto taxiway echo and taxi and hold just past [taxiway] aa. We were given a phone number to call for a possible deviation.I need to be more alert! I'm sure the first officer assumed I was going to stop at the right place. The first officer said that he was going to push the brakes himself. I told him he should have. I really don't know how this can be prevented in the future as it happened so quickly. Other than help with the brakes when the first officer is seeing something you are not; and vice versa. Totally my fault.
