Patent number: 7952681Abstract: A spacer structure includes a first substrate, an overcoat layer, first spacers, second spacers, and a second substrate. The first spacers are disposed in a first region, and the overcoat layer has a first thickness in the first region. The second spacers are disposed in a second region, and the overcoat layer has a second thickness in the second region. The first spacers and the second spacers have the same height, and the first thickness is greater than the second thickness. Accordingly, no gap exists between each of the first spacers and the second substrate; however, a gap exists between each or the second spacers and the second substrate.Type: GrantFiled: December 4, 2008Date of Patent: May 31, 2011Assignee: AU Optronics Corp.Inventor: Po-Yuan Shen
