    Abstract: A display device includes: a substrate including an alignment area in a non-display area, and a display area including a plurality of material layers on the substrate; in the alignment area, a plurality of keys including a first alignment key and a second alignment key. Each alignment key includes a light blocking pattern, a layer pattern and a display pattern. The position of the display pattern within the first alignment key is different from the position of the display pattern within the second alignment key, the layer pattern of the alignment key and one material layer among the plurality of material layers are respective portions of a same material layer on the substrate, and the layer pattern of the first alignment key and the layer pattern of the second alignment key are respective portions of different material layers among the plurality of material layers on the substrate.

    Abstract: A display device includes a lower substrate, a sub-pixel structure, an optical filter layer, a color filter layer, an upper substrate, and an alignment structure. The lower substrate has a display area and a peripheral area surrounding the display area. The sub-pixel structure is disposed in the display area on the lower substrate. The optical filter layer is disposed on the sub-pixel structure. The color filter layer is disposed on the optical filter layer. The upper substrate is disposed on the color filter layer. The alignment structure is disposed in the peripheral area on a bottom surface of the upper substrate, and contains a material equal to a material forming the optical filter layer and the color filter layer.

    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: A display panel including: a first display substrate and a second display substrate. The second display substrate includes: a base substrate; a light control layer disposed on the base substrate and including a first conversion part configured to convert the first color light into a second color light, a second conversion part configured to convert the first color light into a third color light, and a transmission part configured to transmit the first color light; and a nano particle layer disposed between the base substrate and the light control layer and configured to absorb at least one of a first light having an overlapping wavelength range of a wavelength range of the first color and a wavelength range of the third color and a second light having an overlapping wavelength range of a wavelength range of the second color and a wavelength range of the third color.
