Abstract

According to an aspect, a display device capable of outputting individual images to a plurality of viewpoints arranged in a predetermined direction, the display device includes: two light-transmitting substrates that face each other with a liquid crystal layer interposed therebetween; a resin layer that is a light-transmitting layer and stacked between the liquid crystal layer and one substrate positioned on a user side of the two light-transmitting substrates; and a light-shielding barrier provided between the one substrate and the resin layer and having a plurality of openings.

Claims (25)

1. A display device capable of outputting individual images to a plurality of viewpoints arranged in a predetermined direction, the display device comprising:

two light-transmitting substrates that face each other with a liquid crystal layer interposed therebetween;

color filters arranged in the predetermined direction;

a black matrix disposed on boundaries of the color filters, the black matrix having BM portions each overlapping a corresponding one of the boundaries of the color filters;

a resin layer that is a light-transmitting layer and stacked between the liquid crystal layer and one substrate of the two light-transmitting substrates, the one substrate being positioned on a user side of the two light-transmitting substrates; and

a light-shielding barrier provided between the one substrate and the resin layer and having a plurality of openings and barrier portions disposed adjacent to at least one of the openings in the predetermined direction,

wherein one of the barrier portions overlaps corresponding ones of the BM portions that are disposed in a layer different from a layer of the barrier portions, in plan view, and

the one substrate, the light-shielding barrier, the resin layer, the black matrix, and the color filters are stacked in an order as listed.

2. The display device according to claim 1 , wherein

the thickness of the resin layer is based on a first condition and a second condition,

the first condition is an angle formed between a line of light passing through one of the openings and reaching one of two viewpoints adjacent to each other in the predetermined direction and a line of light passing through the opening and reaching the other of the two viewpoints adjacent to each other in the predetermined direction, and

the second condition is an arrangement pitch of the color filters in the predetermined direction, the color filters being individually provided for a plurality of respective sub pixels included in the display device.

3. The display device according to claim 2 , wherein

the color filters are disposed between the liquid crystal layer and the resin layer, and

the thickness of the resin layer corresponds to a thickness obtained by subtracting the thickness of each color filter from a thickness calculated based on the first condition and the second condition.

4. The display device according to claim 2 , wherein the color filters are disposed on an other substrate of the two light-transmitting substrates, the other substrate being positioned on an opposite side of the user side.

5. The display device according to claim 2 , wherein the greatest common divisor of the number of kinds of the sub pixels and the number of images simultaneously output in accordance with the number of the viewpoints is one only.

6. The display device according to claim 5 , wherein the sub pixels adjacent to each other in the predetermined direction are used for outputting of respective images to different viewpoints.

7. The display device according to claim 1 , wherein a length of each of the barrier portions in the predetermined direction is greater than a length of each of the BM portions in the predetermined direction.

8. The display device according to claim 1 , wherein

a length of each of the barrier portions in the predetermined direction is greater than a length of each of the color filters in the predetermined direction.

9. The display device according to claim 1 , wherein

one of the barrier portions having a barrier length overlaps corresponding ones of the BM portions each having a BM portion length that is less than the barrier length, in the predetermined direction.

10. The display device according to claim 1 , wherein

one of the barrier portions having a barrier length overlaps corresponding ones of the color filters each having a color filter length that is less than the barrier length, in the predetermined direction.
