Problems solved by technology

The disadvantage of this structure is that the images viewed by the left eye and the right eye have a certain height difference (the height of the horizontal or vertical bars), resulting in the superposition of two different images, resulting in blurred images, that is, crosstalk (crosstalk) Phenomena that affect the viewing effect of users

Embodiment 1

[0039] This embodiment provides a phase difference plate, such as figure 2 As shown, it includes: a first substrate 1 and a second substrate 2, a first transparent electrode layer 3 and a second transparent electrode layer 4 are respectively formed under the first substrate 1 and above the second substrate 2, and the first transparent electrode layer 3 and above the second transparent electrode layer 4 are respectively formed with an alignment film 5, wherein the function of the alignment film 5 is to initially align the liquid crystal molecules in the liquid crystal layer 6 in the process of manufacturing the phase difference plate of this embodiment .

[0040] The solidified liquid crystal layer 6 is filled between the two alignment films 5. In order to generate two different phase difference values ​​for the light passing through the liquid crystal layer 6, the present embodiment divides the liquid crystal layer into first regions 61 and second regions 61 arranged in a sta...

[0049] This embodiment provides a method for manufacturing a phase difference plate, such as Figure 5 shown, including:

[0050] Step 101 , forming a first transparent electrode layer and a second transparent electrode layer under the first substrate and above the second substrate, respectively.

[0051] Step 102, forming alignment films under the first transparent electrode layer and above the second transparent electrode layer respectively.

[0052] Among them, the function of the alignment film is to initially align the liquid crystal molecules in the liquid crystal layer, so that the liquid crystal molecules have a certain preliminary alignment direction.

[0053] Step 103 , filling the liquid crystal layer between the two alignment films, and the liquid crystal layer is doped with active mesogenic monomers.

[0054] The characteristic of RM monomer is that when it is exposed to light, for example, under the irradiation of ultraviolet rays, it will polymerize with liqui...

Embodiment approach

[0059] As another embodiment of the present invention, the exposed area and the non-exposed area are "L"-shaped areas arranged in a staggered manner, and each "L"-shaped area corresponds to an area of ​​four pixels.

[0060] Step 105: Apply a second voltage to the first transparent electrode layer and the second transparent electrode layer, and at the same time use a mask to expose the liquid crystal layer for the second time, and the area exposed for the second time is the area not exposed in the first exposure area.

[0061] The second voltage in this embodiment is 2-6V. During the second exposure to the liquid crystal layer, the exposure amount is different from the first exposure, and the exposure amount of the second exposure is 10-15mW / cm2. The RM monomer in the liquid crystal layer corresponding to the second exposure area reacts with the liquid crystal molecules to form a polymer, so that the liquid crystal molecules in the liquid crystal layer corresponding to the se...

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a phase difference plate for three-dimensional liquid crystal display and a manufacturing method thereof. Background technique [0002] At present, the display of three-dimensional images is mainly realized by displaying the views for the left eye and the views for the right eye respectively, and the user obtains a sense of depth and a sense of three-dimensionality after feeling different images through the left eye and the right eye. Users need to wear corresponding glasses when watching, wherein the glasses are divided into liquid crystal switch glasses, polarized light glasses and color filter glasses. Taking polarized glasses as an example, the angles of the polarizers of the left and right eyes of the polarized glasses are generally orthogonal. For example, the polarization angle of the left-eye polarizer is 45 degrees, and the polarization angle of the right-eye polari...
