Liquid crystal lens, lens module, and display device

A lens module, comprising a plurality of lens sub-modules configured to be tiled into at least one liquid crystal lens;

• the liquid crystal lens being divided into M dimming areas by at least one horizontal center line and at least one vertical center line;
• a horizontal center line being a straight line passing through an optical center of a liquid crystal lens and extending in a first direction, and a vertical center line being a straight line passing through the optical center of the liquid crystal lens and extending in a second direction;
• the first direction and the second direction being perpendicular to each other;
• a lens sub-module comprising:
• a liquid crystal sub-layer;
• a first electrode sub-layer disposed on a side of the liquid crystal sub-layer;
• in a thickness direction of the liquid crystal lens, the first electrode sub-layer corresponding to N dimming areas of the liquid crystal lens, where N is greater than or equal to 1 and less than or equal to M;
• and
• a second electrode sub-layer disposed on a side of the liquid crystal sub-layer away from the first electrode sub-layer;
• the second electrode sub-layer including an electrode group corresponding to each of the N dimming areas;
• in the thickness direction of the liquid crystal lens, N electrode groups being in one-to one correspondence to the N dimming areas;
• the electrode group includes a row of driving electrodes arranged in the first direction, wherein
• at least one of the N electrode groups is a specific electrode group;
• the specific electrode group includes a plurality of driving electrodes, and tilt angles of the plurality of driving electrodes in the specific electrode group increase in a direction away from the vertical center line in the first direction;
• and a tilt angle of a driving electrode is an included angle between an extending direction of the driving electrode and the second direction.
