Why is my Document Mode: IE7 standards in HTML5 page?

Here is my source code :

<!DOCTYPE html>
<head id="ctl00_ctl00_Head1">                
<title>my page</title>   
<link rel="shortcut icon" href="/favicon.ico" />        
<script type="text/javascript" src="/SiteMain/JS/jquery-1.7.2.min.js"></script>
<script type="text/javascript">


Because you're looking at it from a local or intranet server, and you have the setting 'View all intranet pages in compatibility mode' ticked, probably.
