Reflective liquid crystal panel and display device

A display device comprising a reflective liquid crystal panel and a driving module which drives signals to the reflective liquid crystal panel so that the reflective liquid crystal panel displays an image, wherein the reflective liquid crystal panel comprising a first substrate and a second substrate disposed opposite to each other and a liquid crystal layer disposed between the first substrate and the second substrate, a reflection layer being provided on a side, which is close to the liquid crystal layer, of the first substrate, and a polarizing plate being provided on a side, which is away from the liquid crystal layer, of the second substrate,

• wherein, in a direction from the second substrate to the liquid crystal layer, a unidirectional wavelength converting layer and a quantum dot thin film layer are sequentially laminated between the second substrate and the liquid crystal layer;
• and
• wherein the unidirectional wavelength conversion layer made of an up conversion material is used to convert the incident ambient light into a blue light or an ultraviolet light so as to be provided to the quantum dot thin film layer, and
• the quantum dot thin film layer comprises a plurality of light emitting areas which are arranged in array and can be excited to emit lights of different colors, and each of the light emitting areas corresponds to a sub pixel in the liquid crystal panel.
