Display device and driving method therefor, and display apparatus

A display device comprising:

• a light absorption layer and a liquid crystal element layer disposed on the light absorption layer, the liquid crystal element layer comprising:
• at least two liquid crystal elements stacked, wherein a liquid crystal element of the at least two liquid crystal elements comprises:
• a first substrate, a reflective liquid crystal layer, and a second substrate, wherein the first substrate is located on a side of the reflective liquid crystal layer close to the light absorption layer, and the second substrate is located on a side of the reflective liquid crystal layer away from the light absorption layer;
• operation states of the reflective liquid crystal layer comprise:
• a reflective state and a focal cone state;
• and
• one liquid crystal element of adjacent liquid crystal elements has the reflective liquid crystal layer in the reflective state, with a light reflected by the one liquid crystal element comprising at least a left-handed polarized light;
• other liquid crystal element of the adjacent liquid crystal elements has the reflective liquid crystal layer in the reflective state, with a light reflected by the other liquid crystal element comprising at least a right-handed polarized light.
