I am not sure about regulatory requirements, but some possible reasons:

- Minimize electrical load on takeoff.
- Reduce chance of sparking / ignition in case of a takeoff or landing
- Increase passenger visibility outside to help evacuate the aircraft.

BTW, I have also noticed that TW and UA ask passengers to leave their
window shades up for takeoff and landing.  Maybe more of the visibility
outside issue.
