Another example image 3 As shown, the principle of the crosstalk phenomenon generated by the color filter substrate including the half-wave plate layer shown in Figure 2 is explained. , it means that the viewer's head does not rotate, the image of the display normally passes through the half-wave plate layer 9 and the 3D glasses, the light of the right eye image enters the right eye glass 10, and the light of the left eye image enters the left eye glass 11 (such as image 3 Indicated by the two solid arrows); when When it means that the viewer's head is rotated, due to the oblique incidence of polarized light, the light of the right-eye image will enter the left-eye lens 11 (such as image 3 As shown by the dotted arrow in the center), this will cause crosstalk, and the stereoscopic effect obtained by the viewer will be greatly reduced, which will affect the viewing effect of the viewer

Abstract
The invention relates to the technical field of a liquid crystal display, and particularly discloses a color filter substrate and a manufacturing method thereof as well as a 3D (three-dimensional) liquid crystal display. The manufacturing method comprises the following steps of: step S1, preparing a quarter-wave plate layer on a substrate; step S2, manufacturing a mesh-shaped half-wave plate layer on the quarter-wave plate layer; step S3, preparing a polarizer layer on the mesh-shaped half-wave plate layer; and step S4, manufacturing a three-primary color layer on the polarizer layer. According to the manufacturing method provided by the embodiment of the invention, the mesh-shaped half-wave plate layer and the uniform quarter-wave plate layer are formed on the color filter substrate, so that linear polarization light is converted into circularly polarized light after light is subjected to phase delay through the mesh-shaped half-wave plate layer and the quarter-wave plate layer. Therefore, the occurrence of the crosstalk phenomenon is avoided to a certain extent; and a stereoscopic vision effect of a viewer is ensured.
Description
technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a color filter substrate for 3D display, a manufacturing method thereof, and a 3D liquid crystal display. Background technique [0002] Stereoscopic display technology is a technology that uses a series of optical modulation methods to cause parallax between the left and right eyes of people, so that they can receive different pictures and form a three-dimensional (3D) stereoscopic effect in the brain. Such as figure 1 As shown, it is a schematic diagram of a polarized three-dimensional display in the prior art. A beam of natural light passes through a liquid crystal display (Liquid Crystal Display, LCD) panel 8, and then passes through a half-wave plate layer 9 (retarder). Due to the effect of phase delay, the polarization state of the light will change, and it will be divided into two polarization states 9' and enter the left eye and the right eye respectively,...
