Abstract

The invention belongs to the technical field of stereoscopic display and provides a liquid crystal lens. The liquid crystal lens comprises a first substrate and a second substrate opposite to the first substrate. The first substrate is provided with multiple first electrodes, and the first electrodes are arranged at intervals. When the liquid crystal lens is used for stereoscopic display, multiple liquid crystal lens units which are of the same structures and are arrayed are formed between the first substrate and the second substrate, and every two adjacent liquid crystal lens units share one first electrode. Multiple second electrodes are arranged on the side, facing the first substrate, of the second substrate and arranged at intervals, an opening part is formed between every two adjacent second electrodes, and the center lines of the opening parts and the center lines of the corresponding first electrodes located on the edges of the liquid crystal lens units are located on the same straight line. When the liquid crystal lens is used for stereoscopic display, the crosstalk phenomenon existing at the junction of every two adjacent liquid crystal lens units is obviously reduced. The invention further provides a stereoscopic display device with the liquid crystal lens. The stereoscopic display effect is improved.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to a liquid crystal lens and a stereoscopic display device including the liquid crystal lens. Background technique [0002] The three-dimensional display device that adopts liquid crystal lens to realize three-dimensional display mainly uses two substrates on both sides of the liquid crystal layer to respectively arrange a common electrode and a plurality of driving electrodes, apply a corresponding driving voltage to each driving electrode and apply a common voltage to the common electrode , so that vertical electric fields with different electric field strengths are formed between the two substrates to drive liquid crystal molecules to align to form a variable-focus liquid crystal lens. Therefore, it is only necessary to control the voltage distribution of the driving electrodes, and the refractive index distribution of the liquid crystal lens will change ...
