Do you mean turn off the phone, or turn off the screen?
To turn off the screen, just double tap on a blank area of a home screen. (Not where's there's an icon or widget.) This only works with the stock launcher unless you use extra software.
If you truly mean turn the phone off, you can't. You have to use the power button.
