NEI doesn't appear in regular creative mode you have to use creative + click the big "C" at the top left of your screen to cycle through the modes: Survival, Adventure, Creative, Creative +
Then the item screen on the right should appear. IF in survival mode and Creative + and it still doesn't show up open your inventor and press the letter " O " That will hide/show the NEI items.
Ohh and here is your screenshot
