    Abstract: Provided is a display panel in which a first pixel region, a second pixel region, a third pixel region, and a light-blocking region may be defined. The first substrate may include a base layer; a first color filter layer overlapping the light-blocking region and the first pixel region; a light blocking layer overlapping the light-blocking region; a second color filter layer overlapping the second pixel region; a third color filter layer overlapping the third pixel region; and a step compensation layer disposed on one surface of the light-blocking layer and configured to cover at least a portion of the light-blocking region adjacent to the first pixel region when viewed in a plane.

    Abstract: A display panel includes an upper substrate to which external light is incident, a sealing member which is in a non-display area and couples the upper substrate to a lower display substrate. The upper display substrate includes: a base substrate; a light shielding layer and filter layer each corresponding to the non-display area and absorbing a portion of external light which is transmitted through the base substrate at the non-display area, the filter layer and the light shielding layer having different colors from each other. In a first non-display area of the base substrate which corresponds to the sealing member, only one among the filter layer and the light shielding layer is disposed. In a second non-display area of the base substrate which is adjacent to the first non-display area, both the filter layer and the light shielding layer are disposed.

    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.

    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.
