Abstract
A display panel includes a first pixel area and a second pixel area. A division partition wall includes an opening corresponding to at least the first pixel area. A light conversion pattern for changing the color of source light is disposed inside the opening. An optical pattern is arranged to correspond to the second pixel area. The optical pattern transmits the source light therethrough. The optical pattern may have a shape integrally formed with or different from the division partition wall.

A display panel comprising a first pixel area, a second pixel area, a third pixel area, and a peripheral area adjacent to the first, second, and third pixel areas, the display panel comprising:
- a first light emitting element, a second light emitting element, and a third light emitting element, each of which generates source light and which correspond to the first pixel area, the second pixel area, and the third pixel area, respectively;
- a division partition wall in which first openings corresponding to the first pixel area and the second pixel area are defined and which overlaps the peripheral area and the third pixel area;
- a color filter overlapping the first pixel area and the second pixel area;
- a division pattern in which second openings corresponding to at least the first openings are defined;
- a first light conversion pattern disposed inside an opening corresponding to the first pixel area among the first openings, wherein the first light conversion pattern converts the source light generated in the first light emitting element into first color light;
- and
- a second light conversion pattern disposed inside an opening corresponding to the second pixel area among the first openings, wherein the second light conversion pattern converts the source light generated in the second light emitting element into second color light.
A display panel comprising a first pixel area, a second pixel area, and a peripheral area adjacent to the first and second pixel areas, the display panel comprising:
- a first display element and a second display element, each of which provides source light and which correspond to the first pixel area and the second pixel area, respectively;
- a division partition wall which overlaps the peripheral area and in which first openings corresponding to the first pixel area and the second pixel area are defined;
- a division pattern in which a second opening corresponding to at least the first pixel area is defined;
- a light conversion pattern disposed inside an opening corresponding to the first pixel area among the first openings, wherein the light conversion pattern converts a color of the source light received from the first display element;
- and
- an optical pattern disposed inside an opening corresponding to the second pixel area among the first openings, wherein the optical pattern transmits the source light received from the second display element,
- wherein a portion of the optical pattern overlaps the division partition wall in a plan view.
A method for manufacturing a display panel, which comprises a first pixel area, a second pixel area, a third pixel area, and a peripheral area adjacent to the first, second, and third pixel areas, the method comprising:
- providing a division partition wall in which openings corresponding to the first pixel area and the second pixel area are defined and which overlaps the peripheral area and the third pixel area;
- and
- providing light conversion patterns, which convert a color of incident light, inside the openings,
- wherein the providing the light conversion patterns comprises providing a liquid quantum dot composition into the first openings.
A method for manufacturing a display panel comprising a first pixel area and a second pixel, the method comprising:
- providing a division partition wall in which openings corresponding to the first pixel area and the second pixel area are defined;
- providing a light conversion pattern, which converts a color of incident light, inside an opening corresponding to the first pixel area among the openings;
- and
- providing an optical pattern which transmits the incident light to correspond to an opening corresponding to the second pixel area among the openings,
- wherein the providing the light conversion pattern comprises providing a liquid quantum dot composition into the opening corresponding to the first pixel area, and
