1. A photoluminescent display device comprising:

  • a light source; and

    a photoluminescent display panel adjacent to the light source and comprising a transparent substrate, a pixel unit, and a photoluminescent structure;

    wherein;

    the pixel unit and the photoluminescent structure are disposed on the transparent substrate;

    the pixel unit comprises a red pixel region, a green pixel region and a blue pixel region, wherein the red pixel region, the green pixel region and the blue pixel region are arranged adjacent to one another; and

    the photoluminescent structure, which is disposed on the pixel unit and is facing toward the light source, comprises a first light-conversion layer covering both the red pixel region and the green pixel region and exposing the blue pixel region when projected along a normal direction of the transparent substrate, and a second light-conversion layer disposed on the first light-conversion layer and covering the red pixel region and exposing the green pixel region and the blue pixel region when projected along the normal direction.
