Abstract: According to an exemplary embodiment of the present inventive concept, a method of manufacturing a color conversion display panel includes forming a plurality of light blocking members on a substrate to partition a first region, a second region, and a third region. A blue light blocking filter is formed on the substrate of both the first region and the second region. A color conversion layer including quantum dots is formed on the blue light blocking filter. A transmissive layer is formed on the substrate of the third region. Water vapor is supplied to the color conversion layer, and a barrier layer is formed on the color conversion layer and the transmissive layer.
