Abstract
A reflective liquid crystal panel including a first substrate and a second substrate disposed opposite to each other and a liquid crystal layer. A reflection layer is provided on the first substrate, and a polarizing plate is provided the second substrate. A unidirectional wavelength converting layer and a quantum dot thin film layer are sequentially laminated between the second substrate and the liquid crystal layer. 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. The quantum dot thin film layer includes a plurality of light emitting areas which are arranged in array and can be excited to emit light with different colors. A display device including the reflective liquid crystal panel as mentioned above is also disclosed.
