Flickering LCD on Project

I'm kind of new to this but not THAT new to this :) Yes, I have a breadboard that size, however the power rails are connected all the way through (on both of the boards that I had used)

I'd also like to thank you all for being so patient with me. I am a highschool student, not someone of a legitimate profession in this kind of stuff, but I feel as if you guys treated me like one. I'll be sure to come back to the Arduino.cc forums next time I have a question!

Again, thank you all!
