Abstract: According to one embodiment, an illuminating device includes a lightguide plate including a curved emitting surface, and an incidence surface including a side edge curved along the emitting surface, a printed circuit board facing the incidence surface, and light sources mounted on the printed circuit board. Each light source includes a light-emitting center, a pair of connection terminals, and a central axis extending through the connection terminals and the light-emitting center. The light sources are arranged along a curved mounting line extending along the curved side edge of the incidence surface on the printed circuit board. The light-emitting centers are located on the mounting line, and the central axes are parallel to each other.

Abstract: A display panel includes a light source section, a light guide section, a liquid crystal layer, a partition section, a display section, and a diffraction section. The light source section emits plural lights of different colors. The light emitted from the light source section enters the light guide section. The light that has passed through the light guide section enters the liquid crystal layer. The partition section partitions the liquid crystal layer into plural pixel regions. The partition section includes plural scanning lines and plural black matrices arranged at intervals in an intersecting direction that intersects with a thickness direction of the light guide section. An image formed by the light emitted from the plural pixel regions is displayed on the display section. The diffraction section diffracts the plural lights that have entered the light guide section from the light source section.

Abstract: According to one embodiment, a cover glass has a first side surface and a second side surface facing the first side surface. A reflector is disposed on the second side surface. The reflector is not disposed on the first side surface. Surface roughness of the second side surface is greater than surface roughness of the first side surface.
