Abstract

A display device is provided. The display device includes: a first base; light-emitting elements on the first base and in the pixels, respectively; a second base facing the first base; and a light-blocking/supporting member between the light-emitting elements and the second base and at a boundary of each of the pixels, wherein the light-blocking/supporting member includes a light-blocking portion and a plurality of supporting portions in the light-blocking portion.

Claims (44)

1. A display device comprising:

a first substrate;

a plurality of light-emitting elements on the first substrate;

an encapsulation layer on the plurality of light-emitting elements;

a filler layer on the encapsulation layer;

a plurality of wavelength conversion patterns on the filler layer and overlapping the plurality of light-emitting elements; and

a plurality of color filters on the wavelength conversion patterns, and a first light-blocking member between adjacent ones of the plurality of color filters,

wherein the filler layer comprises a supporting member overlapping the first light-blocking member in a thickness direction.

2. The display device of claim 1 , wherein the supporting member comprises an acrylic based organic material.

3. The display device of claim 1 , wherein the filler layer further comprises a light blocking portion overlapping the first light-blocking member, and a filler between the light blocking portion, and

wherein the supporting member is on the light blocking portion.

4. The display device of claim 3 , wherein a diameter of the supporting member is the same as or smaller than a diameter of the light blocking portion.

5. The display device of claim 3 , wherein the supporting member comprises a plurality of supporting members in the light blocking portion.

6. The display device of claim 3 , wherein a width of the light blocking portion is the same as or greater than a width of the first light-blocking member.

7. The display device of claim 1 , wherein at least one of the plurality of color filters is on one surface of the first light-blocking member, and

a portion of the color filter on the first light-blocking member overlaps the supporting member.

8. The display device of claim 3 , further comprising: a capping layer on a surface of the wavelength conversion patterns which is opposing the first substrate, and

wherein at least portion of the capping layer contacts the light blocking portion.

9. The display device of claim 1 , further comprising: a second light-blocking member between the supporting member and the first light-blocking member, and

wherein the plurality of wavelength conversion patterns is between the second light-blocking member.

10. The display device of claim 3 , wherein the encapsulating layer comprises a first inorganic encapsulation layer on the light-emitting elements, an organic encapsulation layer on the first inorganic encapsulation layer, and a second inorganic encapsulation layer on the organic encapsulation layer, and

wherein at least portion of the second inorganic encapsulation layer contacts the light blocking portion.

11. The display device of claim 1 , wherein each of the plurality of light-emitting elements comprises a first electrode on the first substrate, an organic light-emitting layer on the first electrode, and a second electrode on the organic-emitting layer, and

wherein at least a portion of the organic light-emitting layer overlaps the supporting member.

12. The display device of claim 11 , wherein the second electrode overlaps the first light-blocking member and the plurality of color filters.

13. The display device of claim 11 , further comprising: a bank layer on the first electrode and overlapping the supporting member.

14. The display device of claim 1 , wherein each of the plurality of light-emitting elements comprises a first electrode, a second electrode spaced apart from the first electrode, and a light-emitting layer between the first electrode and the second electrode.

15. A display device comprising:

a first substrate comprising first areas spaced apart from each other in a first direction and a second direction, and a second area between adjacent ones of the first areas;

a plurality of light-emitting elements on the first substrate and at the first area;

an encapsulation layer on the plurality of light-emitting elements;

a filler layer on the encapsulation layer comprising a filler on the first area and a plurality of supporting members on the second area;

a plurality of wavelength conversion patterns on the filler layer and the first area;

a plurality of color filters on the plurality of wavelength conversion patterns and the first area; and

a first light-blocking member between adjacent ones of the plurality of color filters and on the second area.

16. The display device of claim 15 , wherein the filler layer further comprises a light-blocking portion on the second area, and

wherein the plurality of supporting members are in the light-blocking portion.

17. The display device of claim 15 , wherein at least one of the plurality of supporting members does not overlap the first area in the first direction and the second direction.

18. The display device of claim 15 , wherein at least a portion of the plurality of color filters is on the second area, and

wherein a portion of the plurality of color filters that is on the second area overlaps the first light-blocking member and the plurality of supporting members.

19. The display device of claim 15 , wherein further comprising: a second light-blocking member on the second area; and

wherein the plurality of wavelength conversion patterns are between the second light-blocking member.

20. The display device of claim 15 , wherein each of the plurality of light-emitting elements comprises a first electrode on the first substrate, an organic-emitting layer on the first electrode, and a second electrode on the organic-emitting layer, and

wherein at least a portion of the organic-emitting layer is on the second area.
