Abstract

A panel for a display device is provided, which includes a substrate, a sidewall member formed on the substrate and having a plurality of openings, a plurality of color filters formed into the openings and representing a color by incident light, and at least one inspection pattern inspecting a misalignment of the color filters.

Claims

1. A panel for a display device, comprising:

a substrate;

a sidewall member provided on the substrate and having a plurality of openings;

a plurality of color filters provided in the openings; and

at least one inspection pattern for inspecting a misalignment of the color filters.

3. The panel of claim 1, wherein the sidewall member is a light blocking member.

4. The panel of claim 1, wherein a center of the inspection pattern is positioned along a same line as a center of each of the color filters that are arranged along the same row.

5. The panel of claim 1, wherein the inspection pattern is substantially circular and comprises a plurality of alignment lines having a plurality of divisions.

6. The panel of claim 1, wherein the alignment lines intersect each other.

7. The panel of claim 1, wherein the inspection pattern is larger than a drop of ink.

8. The panel of claim 1, wherein each color filter represents one of a red color, a green color, or a blue color.

9. The panel of claim 8, wherein there is at least one inspection pattern arranged for each color filter row having the same color.

10. The panel of claim 1, wherein the panel is a liquid crystal display panel.

11. The panel of claim 10, further comprising:

a plurality of signal lines;

a plurality of transistors coupled with the signal lines; and

a plurality of pixel electrodes electrically coupled with the signal lines through the transistors.

2. The panel of claim 2, wherein the inspection pattern is provided on an edge portion of the sidewall member or an edge portion of the substrate.

12. A method of manufacturing a panel for a display device, comprising:

depositing ink into an inspection pattern;

inspecting a position of the deposited ink in the inspection pattern;

adjusting a position of a substrate or a head of an inkjet printing device to align a center of the deposited ink with a center of the inspection pattern; and

depositing ink into an opening.

13. The method of claim 12, wherein the ink is one of a red color, a green color, and a blue color.

14. The method of claim 12, wherein the sidewall member is a light blocking member.

15. The method of claim 12, wherein the panel is a liquid crystal display panel or an organic electroluminescence display panel.

16. The method of claim 12, wherein the panel comprises:

a plurality of signal lines;

a plurality of transistors coupled with the signal lines; and

a plurality of pixel electrodes electrically coupled with the signal lines through the transistors.

17. A panel for a display device, comprising:

a substrate;

a sidewall member provided on the substrate and including a plurality of openings;

a plurality of organic light emitters provided in the openings and representing a color, respectively; and

an inspection pattern for inspecting a misalignment of the organic light emitters.

18. The panel of claim 17, wherein the inspection pattern is provided on an edge portion of the sidewall member or an edge portion of the substrate.

19. The panel of claim 17, wherein a center of the inspection pattern is positioned along a same line as a center of each of the organic light emitters that are arranged along the same row.

20. The panel of claim 17, wherein the inspection pattern is substantially circular, and comprises a plurality of alignment lines having a plurality of divisions.

21. The panel of claim 17, wherein the alignment lines intersect each other.

22. The panel of claim 17, wherein the inspection pattern is larger than a drop of ink.

23. The panel of claim 17, wherein each organic light emitter represents one of a red color, a green color, or a blue color.

24. The panel of claim 17, wherein there is at least one inspection pattern arranged for each organic light emitter row having the same color.

25. The panel of claim 17, wherein the panel is an organic electroluminescence display panel.

26. The panel of claim 25, further comprising:

a plurality of signal lines;

a plurality of transistors coupled with the signal lines; and

a plurality of pixel electrodes electrically coupled with the signal lines through the transistors.
