Also with more graphics power under the hood the iPad 2 can spend some of that smoothing and anti-alias tricks.
The glass is clearly different. Not sure if its Corning or Asahi but the flex tests that have been done by 3rd parties shows it's far more durable then the iPad 1s glass.
The glass is the same from my understanding, but they found a way to make it thinner and stronger. Less glass is less work to get the graphics to shine, and with the better graphics refreshing, a lot better looking. Also, do not forget that as any screen ages, it has a tendency to darken.
If you read Anandtech.com review ... Anand got a glass expert to analyze the strength of the two different cover glass panels. As I recall they are both of the Gorilla Glass family, but the thinner glass is more flexible, has better edge support (adhesive all around 100), but there was reference to some additive chemicals to enhance the chemical structure.

Purely subjective, but I find the newer screen looks better when side by side with an iPad1.
I can accept the screen would darken over time, but that noticeably just over a year?
