Imagine the 3DS screen is split into tiny columns. Half of these are angled so their image enters one of your eyes, and interlaced 1 for 1 with these are ones angled the other way, towards the other eye. This creates the illusion of 3D, but the downside is that your head must remain in a specific position or the effect is lost, the two images blur.

The 3D is how the system doubles the image on the top screen. When the double images overlap, the brain makes it think that there is depth within the screen making it look like the game is in 3D. That is why only the person who is playing can see the 3D features and not the spectators from the side.
