摘要： According to one embodiment, a display device includes light sources, light guides, interconnects, first electrodes, a second electrode, an insulating layer and a drive unit. The light guides extend in a first direction. The interconnects extend in a second direction. Each of the first electrodes is connected to each of the interconnects. Slits are provided in each of the first electrodes. The second electrode is provided between the first electrodes and the light guides. The insulating layer is provided between the first and second electrodes. The drive unit is connected to the interconnects and the second electrode. The drive unit creates first and second states by changing a voltage between the first and second electrodes. The light is extracted from the light guides in the first state. An intensity of the light extracted in the second state is lower than that in the first state.

摘要： According to one embodiment, a light guide body includes a light guide plate and a prism array unit. The light guide plate has a major surface, a first side surface, and a second side surface on an opposite side to the first side surface. The prism array unit is provided on the major surface to be in contact with the major surface. The prism array unit includes a plurality of prism bodies. Each of the prism bodies extends along a first direction from the first side surface to the second side surface. The prism bodies are disposed to align along a second direction parallel to the major surface and perpendicular to the first direction. A vertex angle of the prism bodies is a substantially right angle. A refractive index of the prism bodies is higher than a refractive index of the light guide plate.
