What is an anti aliased line?
Antialiasing is a technique used in digital imaging to reduce the visual defects that occur when high-resolution images are presented in a lower resolution. Aliasing manifests itself as jagged or stair-stepped lines (otherwise known as jaggies) on edges and objects that should otherwise be smooth.

What is antialiasing transparency?
Transparency Anti-aliasing is a technique of smoothing out jagged edges by well making the texture transparent. So transparent texture means the jagged edges are less visible making the image smoother.
Why does anti-aliasing look blurry?
With the post-processing anti-aliasing method, the smoothing out occurs after the image is rendered and blurs perceived edges. While post-process anti-aliasing can eliminate some of those jaggies, it does tend to make your images look blurry. And the more detailed your game is, the more likely you are to notice this.
