wordpress site not displying properly on android phone

Hi, my site is not displaying properly on an android device. When you go to it, it’s just displaying the top left hand corner of the site. Clicking to another page makes it use the Woothemes Canvas responsive menu and is ok, but it really doesn’t look good when you first click on it.

How do I make it look great right from the first time you look at it? http://www.ad-extra.com.gridhosted.co.uk
