Problems solved by technology
[0003] like figure 1 As shown, there is a transparent area between two adjacent circular polarizing areas. This transparent area will prevent part of the linearly polarized light from being transformed into circularly polarized light. Therefore, this part of the linearly polarized light will also pass through the circular polarizing plates in front of the left and right eyes. At the same time, it is observed by human eyes, causing image crosstalk (crosstalk) and affecting the 3D display effect

Abstract
The invention discloses a three-dimensional (3D) liquid crystal display, which comprises a liquid crystal panel, a graphical half-wave plate, a third polarizer and a graphical phase difference plate, wherein the liquid crystal panel comprises a first substrate and a second substrate which are arranged oppositely; a first polarizer and a second polarizer are respectively arranged outside the first substrate and the second substrate; a liquid crystal layer is sandwiched between the first substrate and the second substrate; the graphical half-wave plate, the third polarizer and the graphical phase difference plate are sequentially attached to the outer side of the second polarizer; and the included angle between the optical axis of the third polarizer and the optical axis of the second polarizer is 2 times that between the optical axis of a half-wave plate area in the graphical half-wave plate and the optical axis of the second polarizer. The 3D liquid crystal display can improve the 3D display effect.
Description
technical field [0001] The invention relates to a three-dimensional liquid crystal display. Background technique [0002] The structure of the current film-type patterned retarder (Film-type patterned retarder) three-dimensional liquid crystal display is as follows: figure 1 As shown, a common liquid crystal panel includes an array substrate and a color filter substrate (not shown in the figure) arranged opposite to each other. A first polarizing plate and a second polarizing plate are respectively provided on the outer sides of the array substrate and the color filter substrate. The array substrate A liquid crystal layer (not shown in the figure) is sandwiched between the color filter and the color filter substrate, and a patterned phase difference plate is pasted on the outside of the second polarizer, and the circularly deflected area in the patterned phase difference plate (that is, the quarter wave plate and the area of the three-quarter wave plate) are slightly smal...
