Abstract: A display device includes a light guide plate, a first light source, a second light source, and a light transmitting portion. The light guide plate includes a first reflecting prism and a second reflecting prism. The first reflecting prism has an inclined surface that reflects the light incident from the first side surface toward the main surface. The second reflecting prism has an inclined surface that reflects the light incident from the second side surface toward the main surface. The longitudinal direction of the inclined surface of the first reflecting prism is parallel or substantially parallel to a line connecting the second light source and the inclined surface of the first reflecting prism.

Abstract: A display device including (i) a light source and (ii) a light guide body which guides light emitted by the light source, and includes: a light guide leg that guides the light entering through a light entrance surface; and a light exit portion connected to the light guide leg and including a reflection design portion which reflects, in a first direction, a portion of the light guided by the light guide leg and another reflection design portion which reflects, in the first direction, another portion of the light. When viewed in the first direction, the reflection design portion is disposed in a first region on a second direction side with respect to a connecting portion of the light exit portion connected to the light guide leg, and the other reflection design portion is disposed in a second region on a third direction side with respect to the connecting portion.

Abstract: A display apparatus includes: a light guide plate; a light source that causes light to be incident on an end surface of the light guide plate; a hiding plate that is provided on a side of an emission surface of the light guide plate, and that includes a light transmission part which transmits light emitted from the emission surface and a light shielding part which has lower light transmittance than the light transmission part; and a colored board that has light reflectance closer to light reflectance of the light shielding part than light reflectance of the light transmission part in each wavelength, and that is provided on a side of a reflection surface of the light guide plate so as to overlap the light transmission part of the hiding plate when viewed from a direction perpendicular to the emission surface of the light guide plate.

Abstract: A display device capable of displaying a desired pattern using a light guide plate in which plural patterns are recorded. In a light guide plate, light sources allowing light to be incident on a first side surface and a second side surface, first incidental side surface light is reflected to an upper surface side by first reflection parts formed on a bottom surface to display a first pattern, and second incidental side surface light from the second light sources is reflected to the upper surface side by second reflection parts formed on the bottom surface to display a second pattern, in which slopes are provided at parts of the first side surface and the second side surface of the light guide plate, and light reflected on a facing reflection surface and propagating in the light guide plate again is reduced by the slopes.

Abstract: A multicolor display apparatus displays a design pattern by reflecting light beams which are incident into a light guide body by arrays of fine shapes and emitting the reflected light beams from the light emission surface, in which, when it is assumed that the gradation values of red, green, blue, and white at a point where a specific color (to be displayed) of the design pattern of the light guide body is displayed using red, green, blue, and white light are set as I(r). I(g). I(b), and I(w), respectively, and when it is assumed that the gradation values of red, green, and blue in the case of displaying a color close to the specific color using only red, green, and blue light without white light are set as Ir, Ig, and Ib, respectively, the fine shapes for each of red, green, blue, and white colors have a height or a pitch which corresponds to the gradation values I(r), I(g), I(b), and I(w) as follows: I(w)=min(Ir, Ig, Ib), ×A/100; I(r)=Ir?I(w); I(g)=Ig?I(w); I(b)=Ib?I(w). Here, A/100 is less than 1.
