    Abstract: A display panel includes a first substrate in which first, second and third pixel areas and a light blocking area are defined, and a second substrate. The first substrate includes a base layer, a first wavelength conversion layer disposed under the base layer, a second wavelength conversion layer disposed under the base layer, an optical layer disposed under the base layer, a first partition layer disposed between the first and second wavelength conversion layers and including a first layer including a same material as that of the optical layer and a second layer spaced apart from the base layer with the first layer interposed therebetween, and a second partition layer disposed between the second wavelength conversion layer and the optical layer.

    Abstract: A display panel includes an upper display substrate, a lower display substrate, and a partition wall. The upper display substrate includes a display area and a non-display area adjacent to the display area. The display area includes pixel areas and a light blocking area adjacent to the pixel areas. The lower display substrate includes display elements configured to emit light having a first color and respectively overlapping the pixel areas. The partition wall includes a partition wall part overlapping the light blocking area and a reflection part disposed on the partition wall part. The upper display substrate includes a base substrate, a color filter layer disposed on the base substrate, and a light control layer disposed on the color filter layer. The light control layer is configured to control the light having the first color. The partition wall is disposed on the light control layer.

    Abstract: A display panel includes an upper display substrate. The upper display substrate includes a base substrate and first to fourth color filters. The first and second color filters overlap first and second pixel areas. The third color filter overlaps a light-blocking area and a third pixel area and has a first opening and a second opening corresponding to the first pixel area and second pixel area, respectively. The fourth color filter overlaps the first pixel area and the second pixel area and has a third opening corresponding to the third pixel area.

    Abstract: The display panel includes an upper display substrate including a display area and a non-display area adjacent to the display area and a lower display substrate that faces the upper display substrate to emit first color light, the lower display substrate including a plurality of display elements respectively overlapping the pixel areas. The display area includes a plurality of pixel areas and a light blocking area adjacent to the pixel areas. The upper display substrate includes a base substrate, a first light control layer on the base substrate to control the first color light, a capping layer including an absorption part overlapping the display area and on the first light control layer and a barrier part overlapping the light blocking area and protruding from the absorption part in a thickness direction of the base substrate, and a second light control layer on the barrier part.
