iPad 3 Screen Bleeding Photo

My brand new iPad 3 with plenty of screen bleeding or light bleeding around the edges.

 

All of my iPads, from 1 to 3, including 3 separate iPad 2's, have all had screen bleeding. The iPad 3 has the least of any of the one's I've owned, but I still don't understand why it has to be there. Why can't they just seal it 100% around the edge? Why do they have to leave spaces unsealed for light to pour into the beautiful screen?
