Try re-booting the iPad again. To do (apologies if you know already):
Hold both the power and home buttons until the screen goes dark and the Apple logo then appears (the slide to unlock screen may or may not appear). Once the logo appears, release the buttons. After a time, your homescreen will appear. Please note that it may take some time for the Apple logo to appear or for your homescreen to appear (or both). This is normal. Eventually, the homescreen will appear.
If the screen still looks like that after the reset/reboot, you'll have to take it in to Apple because then I believe you have a hardware fault. You'll need Apple to repair it or exchange it for a new iPad...
