Back cover and display device including the same

A back cover for a display panel comprises: a plurality of unit plates 110; and a connection unit 120 having one side connected to a first unit plate 111 of the plurality, and another side connected to a second unit plate 112 of the plurality, the second unit plate being spaced apart from, and disposed parallel to, the first unit plate. The connection unit may comprise: first protruding member (121, Figure 2) protruding from the first unit plate; second protruding member (122) protruding from the second unit plate, opposite the first protruding member; and a first elastic member (123) interconnecting the first and second protruding members, and curved toward a side of the first or second unit plate. The connection unit may have a sectional shape of a capital omega "Ω", and may be deformed to withstand tensile or compressive stress from display thermal expansion. The first elastic member may be connected to the first or second protruding member at a first or second angle less than or equal to 90 degrees from the first or second unit plate, first and second angles being relative to a direction in which first and second protruding members are opposite each other.
