The present invention is to provide a display device, which comprises a display body having two opposite sides adjacent to a periphery thereof and each formed with at least one first positioning element respectively, and at least one detachable decorative member made of an elastic material and formed with a second positioning element in two opposite sides adjacent to two end edges thereof respectively. When the second positioning element is inserted into and engaged with the first positioning element corresponding thereto, the elastic deformation force of the decorative member can generate a clamping force for enabling the second positioning element to firmly clamp the first positioning element, protecting the periphery of the display body from being broken due to external impact or abrasion, using the decorative member as an elastic cushioning for packing the display body into a packing box, and reducing the use of packing materials.
