The hinge device foldably combines the first housing and second housing. The flexible display has a folding region folded through the hinge device, a first bending region located at one side of the folding region, and a second bending region located on other side of the folding region, and includes a window layer, a display panel disposed under the window layer, and a support plate disposed under the display panel and including a pattern having at least one opening and/or at least one recess formed at a position corresponding to at least the folding region. The first bending region is configured to refrain from being attached to the first housing and a first hinge plate, and the second bending region is configured to refrain from being attached to the second housing and a second hinge plate.
