Claim 11:
12. A display device, comprising a display panel having a display side, wherein the display panel comprises:
a liquid crystal layer comprising a plurality of liquid crystal molecules;
a light adjustment layer comprising a plurality of light adjustment portions, wherein each of the light adjustment portions comprises a contact interface facing corresponding part of the liquid crystal molecules comprise a contact interface; and
a reflection layer disposed on a side of the liquid crystal layer and the light adjustment layer away from the display side and corresponding to the light adjustment portions;
wherein when one of a refractive index of the liquid crystal molecules and a refractive index of the light adjustment portions near the display side is greater than one of a refractive index of the liquid crystal molecules and a refractive index of the light adjustment portions away from the display side, the contact interface is for an incident light to be totally reflected on the contact interface, and when one of the refractive index of the liquid crystal molecules and the refractive index of the light adjustment portions near the display side is less than one of the refractive index of the liquid crystal molecules and the refractive index of the light adjustment portions away from the display side, the contact interface allows the incident light to pass through;
wherein the reflection layer comprises a reflective light conversion layer and a reflective sheet located under the reflective light conversion layer, wherein the reflective light conversion layer comprises a plurality of reflective light-conversion portions corresponding to the light adjustment portions;
wherein the display panel further comprises a pixel definition layer and a plurality of light absorption layers near the reflective light conversion layer, each of the light absorption layers comprises a plurality of light absorption portions corresponding to the light adjustment portions, each of light absorption portions absorbs the incident light passing through the contact interface, the pixel definition layer comprises a plurality of grooves, and each of the light absorption portions and each of the reflective light-conversion portions are located in a corresponding one of the grooves.
