Display device

1. A display device, comprising:

a light source;

a light guide including a first surface, a second surface opposed to the first surface, and a side surface connecting the first surface and the second surface, and allowing light from the light source to be emitted from the first surface;

a flexible display panel including a display area on which the light from the first surface is incident; and

a first polarizer between the light guide and the display panel,

wherein

the display panel is opposed to the first surface,

an end portion of the display panel is bent toward the second surface along the side surface, and

the first polarizer faces the side surface.

2. The display device of claim 1 , wherein

the first polarizer comprises:

a first layer allowing a first polarization component of light to be transmitted and absorbing a second polarization component; and

a second layer disposed between the first layer and the side surface to allow the first polarization component of light from the side surface to be transmitted and to reflect the second polarization component.

3. The display device of claim 2 , wherein

the display panel includes a light-shielding layer opposed to the side surface, in a bent area.

4. The display device of claim 3 , further comprising:

a second polarizer,

wherein

the display panel is disposed between the first polarizer and the second polarizer, and

the second polarizer is bent along the side surface.

5. The display device of claim 3 , further comprising:

a second polarizer,

wherein

the display panel is disposed between the first polarizer and the second polarizer, and

the second polarizer is not provided in an area where the display panel is bent.

6. The display device of claim 1 , wherein

the display panel includes a reflective layer which reflects light from the side surface, in a bent area.

7. The display device of claim 6 , wherein

the display panel comprises:

a switching element provided in each of pixels in the display area and including a semiconductor layer; and

a metal layer between the semiconductor layer and the light guide, and

the reflective layer is formed of a same material as the metal layer, in a same layer as the metal layer.

8. The display device of claim 3 , wherein

the display panel and an end portion of the first polarizer are located on a side of the second surface.

9. The display device of claim 8 , wherein

the display panel comprises:

a flexible first substrate;

a flexible second substrate opposed to the first substrate;

a frame-shaped sealing member which sticks the first substrate and the second substrate; and

a liquid crystal layer disposed in space surrounded by the first substrate, the second substrate, and the sealing member, and

the sealing member is located on a side of the second surface.

10. The display device of claim 8 , further comprising:

a reflective member which covers the second surface,

wherein

the end portion of the first polarizer is bonded to the reflective member.

11. A display device, comprising:

a light source;

a light guide including a first surface, a second surface opposed to the first surface, and a side surface connecting the first surface and the second surface, and allowing light from the light source to be emitted from the first surface;

a flexible display panel including a display area on which the light from the first surface is incident; and

a reflective member facing the side surface,

wherein

the display panel is bent along the side surface,

the reflective member is located between the display panel and the side surface, in an area where the display panel is bent, and

a total of a thickness of the display panel and a thickness of the reflective member in the area where the display panel is bent is smaller than or equal to a thickness of the display panel in the display area.

12. The display device of claim 11 , wherein

the reflective member is a reflective polarizer.

13. The display device of claim 12 , wherein

the reflective polarizer comprises:

a first layer allowing a first polarization component of light to be transmitted and absorbing a second polarization component; and

a second layer disposed between the first layer and the side surface to allow the first polarization component of the light from the side surface to be transmitted and to reflect the second polarization component.

14. The display device of claim 11 , wherein

the display panel includes a light-shielding layer opposed to the side surface, in a bent area.

15. The display device of claim 11 , further comprising:

a first polarizer and a second polarizer,

wherein

the display panel is disposed between the first polarizer and the second polarizer, and

the second polarizer is bent along the side surface.

16. The display device of claim 11 , further comprising:

a first polarizer and a second polarizer,

wherein

the display panel is disposed between the first polarizer and the second polarizer, and

the second polarizer is not provided in an area where the display panel is bent.

17. The display device of claim 11 , wherein

an end portion of the display panel is located on a side of the second surface.

18. The display device of claim 11 , wherein

the display panel comprises:

a flexible first substrate;

a flexible second substrate opposed to the first substrate;

a frame-shaped sealing member which sticks the first substrate and the second substrate; and

a liquid crystal layer disposed in space surrounded by the first substrate, the second substrate, and the sealing member, and

the sealing member is located on a side of the second surface.

19. The display device of claim 11 , wherein

the reflective member is in contact with the side surface.

20. The display device of claim 11 , wherein

the reflective member includes a layer formed of a metal material.
