Liquid crystal lens and stereoscopic display device

摘要

A liquid crystal lens is comprises: a plurality of lens units (1), and a driver circuit electrically-connected with the plurality of lens units respectively; each lens unit comprises: a common electrode (11), a signal electrode opposite to the common electrode, and a liquid crystal layer provided between the common electrode and the signal electrode; each signal electrode comprises: one or two conductive wires (25) with one end being electrically-connected to the driver circuit, and a resistive block (22) provided on a second substrate and opposite to the common electrode. The resistive block is electrically-connected with the conductive wire(s). Where the driver circuit applies a drive voltage through the conductive wire(s) to the resistive block, the liquid crystal layer provided between the resistive block and the common electrode has a lens function. A stereoscopic display device comprising a same liquid crystal lens is also disclosed.
