Display device including first and second light blocking patterns
A display device includes: a base layer including a display area including an emission area and a non-emission area adjacent to the emission area, and a non-display area around the display area; a light emitting element in the emission area on the base layer; a color filter layer located above the light emitting element; and a light blocking pattern on the light emitting element and including a first light blocking pattern in the non-emission area and a second light blocking pattern in the non-display area. The first light blocking pattern and the second light blocking pattern are different in thickness from each other.
1. A display device comprising:
a base layer comprising:
a display area comprising:
an emission area; and
a non-emission area adjacent to the emission area, and
a non-display area around the display area;
a light emitting element in the emission area and on the base layer;
a color filter layer on the light emitting element; and
a light blocking pattern on the light emitting element and comprising:
a first light blocking pattern in the non-emission area, and
a second light blocking pattern in the non-display area,
wherein the first light blocking pattern and the second light blocking pattern are different in thickness from each other, and
wherein the first light blocking pattern and the second light blocking pattern are in the same layer.
2. The display device of claim 1 , wherein the second light blocking pattern is thinner than the first light blocking pattern in thickness.
3. The display device of claim 1 , wherein the second light blocking pattern is 1 μm or less in thickness.
4. The display device of claim 1 , wherein the emission area comprises a first sub-emission area, a second sub-emission area, and a third sub-emission area, which are spaced apart from each other, and
wherein the color filter layer comprises a first color filter, a second color filter, and a third color filter, which are respectively in the first sub-emission area, the second sub-emission area, and the third sub-emission area.
5. The display device of claim 4 , wherein the first light blocking pattern is between two color filters selected from among the first color filter, the second color filter, and the third color filter, or overlaps with an edge of at least one selected from among the first color filter, the second color filter, and the third color filter.
6. The display device of claim 4 , wherein the second light blocking pattern is at a side surface of at least one color filter selected from among the first color filter, the second color filter, and the third color filter adjacent to the non-display area, or overlaps with at least a portion of the first light blocking pattern adjacent to the non-display area.
7. The display device of claim 4 , further comprising:
a color conversion layer on one surface of the color filter layer,
wherein the color conversion layer comprises:
a light scattering layer on one surface of the first color filter, and comprising light scattering particles;
a first color conversion layer on one surface of the second color filter, and comprising first color conversion particles; and
a second color conversion layer on one surface of the third color filter, and comprising second color conversion particles.
8. The display device of claim 7 , further comprising:
an encapsulation layer on the color filter layer,
wherein the color filter layer is on the color conversion layer, and
wherein the encapsulation layer covers surfaces of the first color filter, the second color filter, the third color filter, the first light blocking pattern, and the second light blocking pattern.
