DISPLAY DEVICE INCLUDING PROTRUDING PLATE
FIG1B is a sectional view that is taken along line A-A of FIG1A of the display device including the resin component in Exemplary embodiment 1
A state where reinforcing layer 9 illustrated in FIG1B is made of resin by insert molding is illustrated. However, as long as members have both light transmittance and strength such as a resin plate or a glass plate, they may be used. Resin that can be used as the resin material of reinforcing layer 9 is a general-purpose molding resin such as polymethylmethacrylate resin (PMMA resin), acrylonitrile ·butadiene ·styrene resin (ABS resin), polystyrene resin (PS resin), or polycarbonate resin (PC resin). In addition thereto, as the resin material of reinforcing layer 9, it is also possible to deal with resin requiring molding at a high temperature, such as resin for optical applications, super engineering resin, or the like. Therefore, display device 80 using the protruding plate can also be used for a lamp cover or the like. Even if the general purpose molding resin such as the PMMA resin, the ABS resin, the PS resin, or the PC resin, resin for the optical use, or the super engineering resin is used for the resin base material of reinforcing layer 9, similar to the above case, when light source 10 is turned off, only the reflected light of protruding plate 1 can be viewed by the external light. When light source 10 is turned on, it is possible to visually recognize shape 13 of an arbitrary character, mark, or pattern which uniformly emits the light to an arbitrary color on the surface of protruding plate 1.

['1. A display device including a protruding plate, comprising: the protruding plate that has a first surface and a second surface on a side opposite to the first surface, and is made of natural wood; a thin film layer that is disposed on the first surface of the protruding plate; a transparent base material; a first concealing layer; a light diffusion layer; a light color toning layer; and a second concealing layer, the transparent base material, the first concealing layer, the light diffusion layer, the light color toning layer, and the second concealing layer being disposed on a side of the second surface of the protruding plate, wherein the first concealing layer has a dispositional relationship in which 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, wherein the transparent base material, the first concealing layer, the light diffusion layer, the light color toning layer, and the second concealing layer are disposed in an arbitrary order except for the dispositional relationship, wherein the protruding plate, the transparent base material, the thin film layer, and the second concealing layer include a greater thickness in this order, wherein the second concealing layer, the first concealing layer, and the  light diffusion layer have a same thickness, wherein the light diffusion layer is thicker than the light color toning layer, and wherein in light transmittance measured when light from a light source is radiated from the side of the second surface to a side of the first surface of the protruding plate, the transparent base material and the thin film layer have a same light transmittance, and 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.', '2. The display device including the protruding plate of Claim 1, further comprising: the light source that radiates the light from the side of the second surface to the side of the first surface of the protruding plate, wherein the first concealing layer has a first light transmitting portion in a shape of a character, a mark, or a pattern, wherein the second concealing layer has a second light transmitting portion in a shape of a character, a mark, or a pattern, wherein the first light transmitting portion is located at a same position as the second light transmitting portion as viewed from the side of the first surface of the protruding plate, wherein when the light of the light source is radiated from the side of the second surface to the side of the first surface of the protruding plate, the light is transmitted through only the first light transmitting portion of the first concealing layer and the second light transmitting portion of the second  concealing layer, and wherein an outer periphery of the first light transmitting portion is larger than an outer periphery of the second light transmitting portion.']
