Abstract: A color conversion panel includes a substrate including a display area including a color conversion layer, a first pixel area, a second pixel area, and a non-pixel area, and a plurality of color filter layers on the substrate. The color filter layers include a first color filter layer in the first pixel area and defining in the non-pixel area, a first alignment pattern, and a first opening spaced from the first alignment pattern, the first pixel area and the second pixel area, and a second color filter layer in the second pixel area, covering the first alignment pattern of the first color filter layer and defining in the non-pixel area a second alignment pattern which overlaps the first opening of the first color filter layer and exposes a portion of the first color filter layer at the first opening, to outside the second color filter layer.

Abstract: A color conversion substrate includes a base substrate including a display area and a non-display area which is adjacent to the display area in a first direction, a color filter layer in the display area, a light blocking member in the non-display area, extending in the first direction and defining a pattern groove of the light blocking member, the pattern groove being in the non-display area, and a refractive layer facing the base substrate with both the color filter layer and the light blocking member therebetween. The refractive layer extends into the pattern groove of the light blocking member and fills the pattern groove.

Abstract: A color-converting substrate includes a color-converting part including a wavelength-converting particle configured to change a wavelength of an incident light to emit a light having a color different from the incident light, a color filter pattern filtering the light emitted from the color-converting part, and a light-reflective layer disposed between the color-converting part and the color filter pattern to selectively reflect a light having a wavelength same as the wavelength of the incident light.
