Abstract
A display device includes a display plate, a micro light source, a first reflecting element and a second reflecting element. The display plate has a pattern. The micro light source emits a light beam. The first reflecting element is arranged beside a first side of the display plate. A first portion of the light beam is reflected by the first reflecting element. A second portion of the light beam is transmitted through the first reflecting element. The second reflecting element is arranged beside a second side of the display plate to reflect the light beam. The light beam is repeatedly reflected by the first reflecting element and the second reflecting element, so that a multiple-luminous effect of the pattern is provided.
