Embodiments of an article comprising a cold-formed glass substrate in a curved shape, a plurality of separate mechanical retainers, and a frame are disclosed. The cold-formed glass substrate has a first major surface, and a second major surface opposing the first major surface. In one more embodiments, the plurality of separate mechanical retainers are attached to the second major surface of the cold-formed glass substrate. The mechanical retainers may be attached to the frame to define a position for each of the plurality of mechanical retainers, such that the mechanical retainers define the curved shape. Embodiments of processes to form such articles are also provided. Such processes can include attaching a plurality of separate mechanical retainers to a flexible glass substrate such that the glass substrate maintains its flexibility, and attaching the mechanical retainers to a frame, such that the mechanical retainers attached to the frame define a cold-formed curved shape for the flexible glass substrate.
