Claim 2:
3. The display module according to claim 2, wherein the display panel further comprises:
a passivation layer, located between the light propagation direction changing structure and the liquid crystal unit; and
a driving electrode, located between the passivation layer and the liquid crystal unit and the driving electrode being configured to drive a deflection of liquid crystal in the liquid crystal unit;
wherein a refractive index of the light propagation direction changing structure is greater than a refractive index of the passivation layer, the refractive index of the passivation layer is greater than a refractive index of the driving electrode, and the refractive index of the driving electrode is greater than a refractive index of the liquid crystal.
