if you could use the USB port power for LCD? that would be shut down / power up by the RPI3 board,
if you use the 5Vpin NOT.

You will need additional external hardware to achieve this.

Pi supply power switch
How does it work?

Once you have finished using your Raspberry Pi, you just shutdown using the sudo halt command, and then a couple of minutes after the full and safe shutdown the Pi Supply Switch cuts the power to the computer. From this point, once again, all you would need to do to restore power to the Pi is touch the on button.

There is also a hard power off button for use in emergencies which immediately cuts the power to your Raspberry Pi. Remember to only use this button when absolutely necessary (e.g. Pi has been frozen for a long time) as it risks corruption of the files on your SD card if done at the wrong moment.

What makes the Pi Supply Switch superior to other makeshift solutions available is that it allows you to restart the Raspberry Pi using the sudo reboot command without the power turning itself off. Perfect!

Or http://www.uugear.com/product/wittypi2/ which includes a RTC and can start/stop your RPi on a timer schedule.
