By coincidence, I just read this:

  Hidden div's -- don't do it!
  It can be tempting to add all the content relevant for a rich snippet
  in one place on the page, mark it up, and then hide the entire block
  of text using CSS or other techniques. Don't do this! Mark up the
  content where it already exists. Google will not show content from
  hidden div's in Rich Snippets, and worse, this can be considered
  cloaking by Google's spam detection systems. [1]
