Miss Chances (see the wizards site)
Each type of miss chance does not stack with itself. The highest miss chance (or the one that qualifies in any case) takes precedence over the others. Different types are not combined, but are rolled separately.
Type 1: B/c you are difficult or impossible to see.*
ex. Concealment/Cover + Invisibility + Blur + Most Untyped
*A target who is blind ignores this type of miss chance, but has penalties of their own.
Type 2: B/c you are not there, are partially there, are sometimes there, or are sort of there.
ex. Incorporeality + Blink + Flicker + Some Untyped

The maximum for any single roll is 50%. The maximum number of rolls is 2 (one for each type), so the maximum miss chance is 75% (the chance of one of the rolls landing as a miss).

Following these rules displacement would fall under type two, because it makes you appear as if you were 2ft away. However displacement says the bonus is type 1 in its description. As such the displacement ability contradicts itself. By raw it is of both types and therefore does not stack with either.
How does all that work with bestow curse then?
