Abstract

A display device including a protruding-plate includes the protruding-plate, a thin-film-layer, a transparent-base-material, a first-concealing-layer, a light-diffusion-layer, a light-color-toning-layer, and a second-concealing-layer. The first-concealing-layer is disposed closer to the protruding-plate than the second-concealing-layer and the light-color-toning-layer to the protruding-plate. The protruding-plate, the transparent-base-material, the thin-film-layer, and the second-concealing-layer include a greater thickness in this order. The second-concealing-layer, the first-concealing-layer, and the light-diffusion-layer have a same thickness. The light-diffusion-layer is thicker than the light-color-toning-layer. The transparent-base-material and the thin-film-layer have a same light transmittance. The thin-film-layer, the protruding-plate, the light-diffusion-layer, the light-color-toning-layer, the first-concealing-layer, and the second-concealing-layer have a higher light transmittance in this order.
