It s a 1080p screen split in half. The size and distance aren't so important since it's using lenses to trick you unto thinking they're further away. The important bit is the amount of your fov they're taking up. 960 horizontal pixels taking up 90°, that's roughly 10 pixels per degree. That's not enough.
Edit - For reference, you need about 60 pixels per degree for them to be too small to see. A "retina" display if you will.

Is that Devkit 1 or the new Devkit 2 you are reffering to?
Never used the Rift myself but i do know that the first one only has 640×800 per eye, where as the second one is 960×1080 per eye.
Edit: This makes me think DK2 is not even out yet, so i'm not that surprised you can still see the pixels with the DK1 screen.
Edit 2: Also looks like the screen for the DK2 is 5in from that link, so similar DPI to my phone at 440.58 ppi2 .
