Liquid crystal lens, manufacturing method of liquid crystal lens and display device

Abstract

The invention provides a liquid crystal lens, a manufacturing method of the liquid crystal lens, and a display device, and belongs to the technical field of display. The liquid crystal lens comprises a first substrate, a second substrate, a liquid crystal layer, a first transparent electrode layer, a first liquid crystal alignment layer, a second transparent electrode layer and a second liquid crystal alignment layer, wherein the liquid crystal layer is located between the first substrate and the second substrate, the first transparent electrode layer and the first liquid crystal alignment layer are located on the first substrate and are close to one side of the liquid crystal layer, and the second transparent electrode layer and the second liquid crystal alignment layer are located at the portion, close to one side of the liquid crystal layer, of the second substrate. The liquid crystal lens further comprises a flat layer arranged between the first transparent electrode layer and the first liquid crystal alignment layer. According to the liquid crystal lens, the flat layer is formed between the first transparent electrode layer and the first liquid crystal alignment layer, and the first liquid crystal alignment layer moves the position with the weaker lateral electric field, so that liquid crystal dislocation is reduced, and the refraction effect of the liquid crystal lens is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal lens, a manufacturing method thereof, and a display device. Background technique [0002] Over the years, people have developed various display technologies for visualizing stereoscopic images. The existing stereoscopic display technologies mainly include cylindrical lens grating stereoscopic display, slit grating stereoscopic display and holographic stereoscopic display. These autostereoscopic display systems can display multiple images from different viewpoints in time or space. [0003] In order to achieve a better three-dimensional display effect, at present, the liquid crystal lens adopts the design of oblique electrodes, such as figure 1 As shown, the liquid crystal lens includes a first substrate 1, a second substrate 2, a liquid crystal layer 3 between the first substrate 1 and the second substrate 2, and a first transparent lens located on the side of ...

AI Technical Summary

Problems solved by technology

[0004] like figure 2 As shown, in the liquid crystal lens element with oblique electrodes, there is a large lateral electric field near the electrode, where the liquid crystal pretilt direction conflicts with the electric field direction, thus causing liquid crystal phase misalignment, and the refractive index here The change is not smooth, thus reducing the refraction effect of the liquid crystal lens
