A display apparatus includes: a display module configured to display an image and to be folded about a folding axis at a folding area defined on a plane; a support member below the display module; and a protective member between the display module and the support member. The support member includes a folding part overlapping the folding area and configured to be folded about the folding axis, and the folding part includes a plurality of joint portions extending parallel to the folding axis and connected to each other. Each of the joint portions includes a support surface supporting the display module, and when the support member is folded, a cusp point is formed between adjacent ones of the support surfaces on a cross-section.
