Abstract
According to one embodiment, a display device includes, a first transparent substrate having a side surface and a main surface, a first alignment film disposed along the main surface, a first transparent layer located between the first transparent substrate and the first alignment film, a second transparent substrate, a pixel electrode electrically connected to a switching element, a liquid crystal layer, and a light-emitting element opposed to the side surface. The first transparent layer overlaps a part of the pixel electrode and has a lower refractive index than the first transparent substrate.
Claims12
A display device comprising:
- a first substrate;
- a second substrate;
- a liquid crystal layer held between the first substrate and the second substrate and containing a stripe-shaped polymer and liquid crystal molecules;
- a light-emitting element;
- and
- pixels arrayed in a matrix, wherein
- the first substrate comprises a first transparent substrate having a side surface opposed to the light-emitting element, a first alignment film contacting the liquid crystal layer, and a first transparent layer located between the first transparent substrate and the first alignment film,
- the second substrate comprises a second transparent substrate, a second alignment film contacting the liquid crystal layer, and a second transparent layer located between the second transparent substrate and the second alignment film,
- the first transparent layer and the second transparent layer are insulating layers, and
- an installation area per pixel of the first transparent layer is less than an installation area per pixel of the second transparent layer.
