Abstract: Provided is a display device in a mechanical method using wind, vibration. The mechanoluminescent display device includes a substrate having a predetermined shape, and projections formed with a predetermined pattern on the substrate. The projections are formed of a mixture of a stress luminescent material emitting light by mechanical energy which is applied and a stress transmission material transmitting the mechanical energy applied from the outside to the stress luminescent material.
