Abstract

According to an aspect, a display device includes: a plurality of pixels arranged in a first direction; a light source configured to emit light to the pixels; a light-blocking member disposed between the pixels and the light source and provided with slits extending in a direction intersecting the first direction; a first reflector that faces the light-blocking member with the light source in between and reflects light to the light-blocking member; a second reflector that covers at least part of the light source side of the light-blocking member and reflects light to the light source; and a reflective polarizer that is disposed between the first reflector and the pixels, transmits light polarized in a second direction, and reflects light polarized in a direction intersecting the second direction.

Claims (12)

1 . A display device comprising:

a plurality of pixels arranged in a first direction;

a light source configured to emit light to the pixels;

a light-blocking member disposed between the pixels and the light source and having slits extending in a direction intersecting the first direction;

a first reflector that faces the light-blocking member with the light source in between and reflects light to the light-blocking member;

a second reflector that covers at least part of the light source side of the light-blocking member and reflects light to the light source; and

a reflective polarizer that is disposed between the first reflector and the pixels, transmits light polarized in a second direction, and reflects light polarized in a direction intersecting the second direction.

2 . The display device according to claim 1 , wherein the reflective polarizer is disposed between the light-blocking member and the pixels.

3 . The display device according to claim 1 , wherein the reflective polarizer is disposed between the light source and the light-blocking member.

4 . The display device according to claim 3 , wherein the reflective polarizer overlaps a diffusion layer that diffuses light.

5 . The display device according to claim 1 , wherein the light-blocking member covers the second reflector in a plan view from the pixel side.

6 . The display device according to claim 1 , wherein asperities are formed on the light source side of the second reflector.
