[0007] However, because the liquid crystal molecules are affected by the alignment film and the liquid crystal molecules on the edge of two adjacent lens units are pushed against each other, when the maximum voltage is applied to the strip electrodes on the edge of two adjacent liquid crystal lenses, the two The liquid crystal molecules corresponding to the strip electrodes on the edge of the adjacent liquid crystal lens cannot stand completely straight, and the situation cannot be improved by increasing the voltage, resulting in the actual n eff greater than n 0 , and then cause 3D crosstalk, etc., affecting the 3D display effect

Abstract
The invention discloses a liquid crystal lens and a liquid crystal display device. The liquid crystal lens comprises a first substrate and a second substrate arranged oppositely, and a liquid crystal layer clamped between the first substrate and the second substrate. A metal layer, an insulating layer and an electrode layer are laminated on one side, adjacent to the first substrate, of the second substrate, the electrode layer comprises multiple spaced electrodes, and the electrodes, applied with the highest voltage, in the spaced electrodes are lower than the adjacent electrodes. The actual effective refractive index of liquid crystals corresponding to the electrodes applied with the highest voltage and liquid crystal molecules corresponding to the electrodes applied with the highest voltage is approximate to the actual effective refractive index under the ideal condition, 3D (three-dimensional) crosstalk can be reduced, and 3D display effect is improved.
Description
technical field [0001] The present application relates to the technical field of display equipment, in particular to a liquid crystal lens and a liquid crystal display device. Background technique [0002] Stereoscopic display devices usually use naked-view 3D (tree dimensions, 3D) display, which mainly converts the left and right parallax displayed on the display panel to The images are sent to the user's left and right eyes respectively, and then fused by the brain, so that the viewer can obtain stereoscopic perception. [0003] Among them, optical splitting devices such as liquid crystal lenses mainly use transparent materials to make cylindrical lens arrays of a certain size, and through their refraction, the light of different pixels in the display panel is emitted in different polarization directions, thereby obtaining the separation of parallax images. [0004] see figure 1 , figure 1 It is a structural schematic diagram of an embodiment of a lens unit of a liquid ...
