The Oil Pavilion, one of the most popular Expo pavilions, earned two Guinness World Records for its huge LED screen and 4D science documentary Sunday -- the last day of Expo 2010.

The pavilion's triangular LED screen is the world's largest screen using polycarbonate sheet technology, and its 4D film "Oil Dream" has been screened 13,166 times during the Expo, setting another record.

The 4D documentary depicts the discovery of petroleum in China.

During the 184-day Expo, the Oil Pavilion received 3,611,388 visitors, topping the list of pavilions with the longest queuing time for 133 days.

The pavilion turned off its lights at 11pm Sunday and the last visitor received a plushy "Oil Baby," the pavilion's mascot.
