Display device capable of adjusting a viewing angle and method of manufacturing the same
A display device includes a substrate, a light emitting diode disposed on the substrate and light control patterns overlapping the light emitting diode, the light control patterns including at least three light blocking patterns and at least two organic patterns alternately disposed on the light emitting diode and spaced apart from each other.
1 . A display device comprising:
a substrate;
a light emitting diode disposed on the substrate; and
light control patterns overlapping the light emitting diode, the light control patterns including at least three light blocking patterns and at least two organic patterns alternately disposed on the light emitting diode and spaced apart from each other.
2 . The display device of claim 1 , further comprising:
an organic film disposed on the light emitting diode and disposed between adjacent light control patterns.
3 . The display device of claim 2 , wherein the organic film contacts the at least two organic patterns and includes the same material as the at least two organic patterns.
4 . The display device of claim 2 , wherein the organic film covers upper surfaces of the light control patterns.
5 . The display device of claim 1 , wherein the light blocking patterns and the at least two organic patterns included in one of the light control patterns overlap each other.
6 . The display device of claim 1 , wherein the light control pattern includes,
a first light blocking pattern disposed on the light emitting diode;
a first organic pattern disposed on the first light blocking pattern;
a second light blocking pattern disposed on the first organic pattern;
a second organic pattern disposed on the second light blocking pattern; and
a third light blocking pattern disposed on the second organic pattern.
7 . The display device of claim 6 , wherein a thickness of the first organic pattern and a thickness of the second organic pattern are equal to each other.
8 . The display device of claim 6 , wherein a thickness of the first organic pattern and a thickness of the second organic pattern are different from each other.
9 . The display device of claim 1 , wherein the light blocking patterns include a conductive material, a black pigment, or a black dye.
10 . The display device of claim 1 , wherein the light blocking patterns include molybdenum-tantalum oxide (MTO).
11 . The display device of claim 1 , wherein each of the light blocking patterns has a multilayer structure.
12 . The display device of claim 11 , wherein the multilayer structure is at least one selected from the group consisting of MTO/Mo, MTO/Ti, MTO/Al, MTO/Mo/MTO, MTO/Ti/MTO, and MTO/Al/MTO.
