  • Patent number: 7952681
    Abstract: 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.

  • Patent number: 7924358
    Abstract: A spacer structure of a display panel includes a first substrate, a second substrate, a spacer, and a spacer pad. The spacer is disposed on a side of the first substrate facing the second substrate, and the spacer pad is disposed between the second substrate and the spacer. The spacer pad has a non-linear structure lodged in the spacer, and therefore restrains the spacer from moving with respect to the second substrate in the plane parallel to the surface of the second substrate.
