Embodiment Construction

[0052] As mentioned in the background art section, the utilization rate of the optical path difference of the liquid crystal lens in the prior art is relatively low.

[0053]The inventors found that the reason is that the utilization rate of the optical path difference of the liquid crystal lens is determined by the properties of the liquid crystal molecules in the liquid crystal layer and the voltage applied across the liquid crystal layer. When all the liquid crystal molecules in the liquid crystal layer are reversed, the optical path difference of the liquid crystal lens is the maximum optical path difference: the refractive index Δn of the liquid crystal molecules in the liquid crystal layer is multiplied by the thickness d of the liquid crystal lens. However, when a voltage is applied to both ends of the liquid crystal layer, since the liquid crystal layer is provided with an alignment film facing the upper substrate and the lower substrate, the molecules in the liquid cry...

Abstract

The invention discloses a liquid crystal lens manufacturing method and a liquid crystal lens. The method comprises a first step of obtaining an ideal distribution curve of optical path differences of different positions of the liquid crystal lens away from the center of the liquid crystal lens, and marking the ideal distribution curve as an ideal curve; a second step of manufacturing a second transparent high-resistance layer according to the ideal curve, enabling impedance distribution in the second transparent high-resistance layer to be matched with optical path difference distribution in the ideal curve; and a third step of utilizing the second transparent high-resistance layer to manufacture the liquid crystal lens. According to the liquid crystal lens and the manufacturing method for manufacturing the liquid crystal lens, the impedance distribution in the second transparent high-resistance layer to be matched with the optical path difference distribution in the ideal curve, so that in the liquid crystal lens manufactured by utilizing the second transparent high-resistance layer, a distribution curve of optical path differences at different positions away from the center of the liquid crystal lens and the ideal distribution curve of the different positions of the liquid crystal lens away from the center of the liquid crystal lens are high in goodness of fit, and the utilization rate of the optical path differences in the liquid crystal lens is improved.
