Display device having light control layer that limits viewing angle and manufacturing method thereof

1 . A display device, comprising:

a light-emitting device disposed on a substrate and including an emission layer; and

a light control layer disposed on the light-emitting device, wherein the light control layer includes:

a plurality of light blocking patterns extending in a first direction and spaced apart from each other in a second direction intersecting the first direction, and

a transmission layer disposed among the plurality of light blocking patterns and including a plurality of transparent organic layers and a plurality of transparent inorganic layers,

ones of the plurality of transparent organic layers and ones of the plurality of transparent inorganic layers are alternately stacked on each other, and

widths of each of the plurality of transparent organic layers in the second direction between neighboring ones of the plurality of light blocking patterns are equal to each other.

2 . The display device of claim 1 , wherein

the transmission layer includes a plurality of protrusions and a plurality of depressions that include a plurality of concave portions and a plurality of convex portions, respectively, on a side extending to the light blocking pattern.

3 . The display device of claim 2 , wherein

each of the plurality of transparent organic layers extend to the light blocking pattern at ones of the plurality of concave portions of the transmission layer, and

each of the plurality of transparent inorganic layers extend to the light blocking pattern at the plurality of convex portions of the transmission layer.

4 . The display device of claim 1 , wherein

a width of each of the plurality of transparent organic layers is different from a width of each of the plurality of transparent inorganic layers.

5 . The display device of claim 4 , wherein

the width of each of the plurality of transparent organic layers is less than the width of each of the plurality of transparent inorganic layers.

6 . The display device of claim 1 , wherein

each of the plurality of transparent organic layers have a greater etch rate than each of the plurality of transparent inorganic layers, and

the light blocking pattern has a striped pattern in a plan view.

7 . The display device of claim 6 , wherein

the transmission layer also has a striped pattern in a plan view, and

the light blocking pattern and the transmission layer are alternately disposed in the second direction.

8 . The display device of claim 1 , wherein

portions of each of the plurality of light blocking patterns do not overlap any of the plurality of transparent inorganic layers in a plan view.

9 . The display device of claim 1 , wherein

each of the plurality of transparent inorganic layers have a width that extends in the second direction between neighboring ones of the plurality of light blocking patterns.

10 . A method for manufacturing a display device, comprising:

forming a light-emitting device on a substrate;

forming an encapsulation layer that covers the light-emitting device;

forming a transparent material layer by alternately stacking a transparent organic layer and a transparent inorganic layer on each other on the encapsulation layer;

forming a hard mask pattern on the transparent material layer,

etching the transparent material layer and forming a transmission pattern with the hard mask; and

applying a light blocking material for filling an opening between the transmission pattern, wherein the transparent organic layer and the transparent inorganic layer are etched simultaneously to form the opening during the etching of the transparent material layer.

11 . The method of claim 10 , wherein

the transmission pattern includes protrusions and depressions on a surface disposed toward the opening.

12 . The method of claim 10 , wherein

a width of the transparent organic layer is less than a width of the transparent inorganic layer.
