Abstract
According to one embodiment, a display device includes a light guide, a first transparent substrate, a second transparent substrate, a plurality of light-emitting elements disposed along a first direction, a liquid crystal layer containing stripe-like polymers and liquid crystal molecules, and a transparent layer. The transparent layer includes a plurality of strip portions disposed along the first direction, extending in a second direction and having a refractive index lower than that of the second transparent substrate. Each of the strip portions includes a first end portion located on a side facing the light-emitting elements and a linear second end portion opposite to the first end portion.
Claims15
A display device comprising:
- a light guide;
- a first transparent substrate;
- a second transparent substrate disposed between the first transparent substrate and the light guide;
- a plurality of light-emitting elements aligned along a first direction;
- a liquid crystal layer disposed between the first transparent substrate and the second transparent substrate and containing strip-like polymers and liquid crystal molecules;
- and
- a transparent layer disposed between the first transparent substrate and the light guide,
- wherein
- the transparent layer comprises a plurality of strip portions disposed along the first direction, extending along a second direction perpendicular to the first direction, and having a refractive index lower than that of the second transparent substrate,
- each of the plurality of strip portions comprises a first end portion located on a light-emitting element side of the respective strip portion and a linear second end portion on an opposite side to the first end portion,
- each of the plurality of strip portions comprises a first portion surrounded by the first end portion and a first edge and a second edge which face each other, and
- the first edge and the second edge extend in directions different from each other.
An illumination device comprising:
- a light guide;
- a plurality of light-emitting elements aligned along a first direction;
- and
- a transparent layer,
- wherein
- the transparent layer comprises a plurality of strip portions disposed along the first direction, extending along a second direction perpendicular to the first direction, and having a refractive index lower than that of the light guide,
- each of the plurality of strip portions comprises a first end portion located on a light-emitting element side of the respective strip portion and a linear second end portion on an opposite side to the first end portion,
- each of the plurality of strip portions comprises a first portion surrounded by the first end portion and a first edge and a second edge which face each other, and
- the first edge and the second edge extend in directions different from each other.
