Fix is below. But don't do this until you've added current-limiting resistors for the backlight! Anywhere from 220 Ohm to 1K should suffice. Failure to do this will burn out the LEDs pretty quickly.
On long breadboards like that, the power rails aren't continuous down the whole length. See the slightly longer gap in the middle? Put jumper wires across there, or just move the +5V across that space.
