Abstract

According to one embodiment, a display device includes a first substrate, a second substrate including a first end portion and a second end portion located at a position different from the first end portion, a polymer dispersed liquid crystal layer disposed between the first substrate and the second substrate, a light source device located above the first substrate and disposed along the first end portion, and a light-shielding member disposed on at least a part of the second end portion.

Claims (41)

1 - 20 . (canceled)

21 . A display device, comprising:

a first substrate including a first end portion;

a second substrate including a second end portion adjacent to the first end portion, and a third end portion;

a liquid crystal layer disposed between the first substrate and the second substrate;

a light source device located along the third end portion;

a reflective member; and

a third substrate including a fourth end portion adjacent to the second end portion, wherein

the second end portion and the third end portion are separate from each other, and

the reflective member covers the second end portion, the third end portion, and the fourth end portion.

22 . The display device according to claim 21 , wherein the liquid crystal layer includes a polymer and a liquid crystal molecule.

23 . The display device according to claim 21 , wherein the liquid crystal layer includes a polymer formed of a polymeric material and liquid crystal molecules dispersed in the polymer.

24 . The display device according to claim 21 , wherein the first end portion and the second end portion are parallel in a cross-sectional view.

25 . The display device according to claim 21 , wherein

the second substrate includes a surface intersecting the second end portion, and

the surface, the second end portion, and the fourth end portion form a step.

26 . The display device according to claim 25 , wherein the reflective member is separated on the surface.

27 . The display device according to claim 25 , wherein the reflective member covers the surface.

28 . The display device according to claim 21 , wherein the second substrate and the third substrate face each other without being separated by a polarizer in between.

29 . The display device according to claim 21 , wherein an outer shape of the second substrate has a curved shape.

30 . The display device according to claim 21 , further comprising a diffusing member between the second end portion and the reflective member.

31 . A display device, comprising:

a first substrate including a first end portion;

a second substrate including a second end portion adjacent to the first end portion, and a third end portion;

a liquid crystal layer disposed between the first substrate and the second substrate;

a light source device located along the third end portion;

a diffusing member; and

a third substrate including a fourth end portion adjacent to the second end portion, wherein

the second end portion and the third end portion are separate from each other, and

the diffusing member covers the second end portion, the third end portion, and the fourth end portion.

32 . The display device according to claim 31 , wherein the liquid crystal layer includes a polymer and a liquid crystal molecule.

33 . The display device according to claim 31 , wherein the liquid crystal layer includes a polymer formed of a polymeric material and liquid crystal molecules dispersed in the polymer.

34 . The display device according to claim 31 , wherein the first end portion and the second end portion are parallel in a cross-sectional view.

35 . The display device according to claim 31 , wherein

the second substrate includes a surface intersecting the second end portion, and

the surface, the second end portion, and the fourth end portion form a step.

36 . The display device according to claim 35 , wherein the diffusing member is separated on the surface.

37 . The display device according to claim 35 , wherein the diffusing member covers the surface.

38 . The display device according to claim 31 , wherein an outer shape of the second substrate has a curved shape.

39 . The display device according to claim 31 , wherein the second substrate and the third substrate face each other without being separated by a polarizer in between.

40 . The display device according to claim 31 , wherein the diffusing member is an anisotropically diffusing member.
