A display apparatus includes a first substrate and a second substrate disposed in opposition to one another and connected to one another to form a shroud, the first substrate and the second substrate being connected to form a first joint at a first lateral end of the shroud, a second joint at a second lateral end of the shroud and a third joint formed at a lower portion of the shroud, the third joint including a first base connection member rotatably depending from a lower portion of the first substrate and a second base connection member rotatably depending from a lower portion of the second substrate, the third joint being located at a first position in the shroud with the shroud in a compressed state and being located in a second position in the shroud with the shroud in an uncompressed state. The display apparatus also includes a resilient member connecting the first joint to the third joint and connecting the second joint to the third joint to bias the third joint from the first position to the second position when the shroud is the uncompressed state.
