My iPhone screen has developed a large broken area (see attached photos). The area still responds perfectly to touch input, but obviously I can’t see anything within the area. I’ve tried resetting and restoring the phone but it doesn’t fix the problem. Would a new LCD fix the problem or is the logic board itself broken?

From your pictures it looks like it’s only your screen that is damaged. If the board was damaged it would most likely not provide any video to the screen. Replacing the screen is not very difficult, but will probably run more expensive than getting a newer iPhone 5 or 5s, as this is an old phone. A quick search on this site showed no inventory.
