Detailed Description
In order to further explain the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, but not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The first embodiment is as follows:
the embodiment discloses a liquid crystal display panel, which at least comprises a liquid crystal box, wherein the liquid crystal box comprises an upper substrate, a lower substrate and a liquid crystal layer clamped between the upper substrate and the lower substrate; the liquid crystal box is provided with a plurality of retaining walls which are continuously arranged along the row direction and/or the column direction on the surfaces of the upper substrate and the lower substrate, which are close to the liquid crystal layer, respectively, wherein the retaining walls are polymers formed by polymerizing reactive liquid crystal monomers. The liquid crystal layer comprises liquid crystal molecules and reactive liquid crystal monomers dispersed in the liquid crystal molecules, and the reactive liquid crystal monomers are polymerized by ultraviolet irradiation to form polymers to form the retaining wall.
FIG. 1 is a schematic cross-sectional view illustrating a first liquid crystal cell of a liquid crystal display panel without being irradiated with UV light according to an embodiment of the present disclosure; fig. 2 is a schematic cross-sectional view of a first liquid crystal cell of a liquid crystal display panel according to an embodiment of the disclosure after being irradiated with ultraviolet light. Referring to fig. 1 to 2, the liquid crystal display panel disclosed in this embodiment includes a first liquid crystal cell 10 for adjusting a viewing angle, where the first liquid crystal cell 10 includes a first substrate 11, a first electrode 12, a first alignment layer 13, a first liquid crystal layer 14, a second alignment layer 15, a second electrode 16, and a second substrate 17, which are sequentially disposed; the first liquid crystal layer 14 includes liquid crystal molecules 141 and reactive liquid crystal monomers 142 dispersed in the liquid crystal molecules 141. The first liquid crystal cell 10 has a plurality of first walls 19 continuously arranged along the row direction and the column direction on the surface of the opposite side of the first alignment layer 13 and the second alignment layer 15, and the first walls 19 are polymers formed by polymerizing the reactive liquid crystal monomer 142.
Specifically, the Reactive liquid crystal monomer (RM) 142 is a double-bond-containing phototaxis monomer, and after uv irradiation, a polymer formed by polymerization of the Reactive liquid crystal monomer is cured to form the first retaining wall 19 structure.
In the embodiment, the liquid crystal display further includes a lower polarizer (not shown) located outside the first substrate 11 and an upper polarizer (not shown) located outside the second substrate 17, and the polarizing axes of the upper polarizer and the lower polarizer are orthogonal.
In this embodiment, the first electrode 12 and the second electrode 16 are viewing angle control electrodes, and the viewing angle adjusting function of the first liquid crystal cell 10 is realized by applying voltages to the first electrode 12 and the second electrode 16 to form different voltage differences.
Specifically, the liquid crystal molecules 141 are positive liquid crystal molecules. In the initial state (i.e. no voltage is applied to the first electrode 12 and the second electrode 16 or the same voltage is applied), the positive liquid crystal molecules in the first liquid crystal layer 14 are in a lying posture parallel to the first substrate 11 and the second substrate 17, and the long axis direction of the positive liquid crystal molecules is substantially parallel to the surfaces of the first substrate 11 and the second substrate 17 (see fig. 1 and 2). In practical applications, the positive liquid crystal molecules in the first liquid crystal layer 14 and the first and second substrates 11 and 17 may have a smaller initial pretilt angle, and the initial pretilt angle may range from greater than or equal to 0 degrees to less than or equal to 10 degrees, that is: 0 DEG < theta < 10 DEG, theta is the initial pretilt angle.
When there is no voltage difference (the voltage difference is 0V) or a small voltage difference (e.g. the voltage difference is less than 1V) between the first electrode 12 and the second electrode 16, the positive liquid crystal molecules in the first liquid crystal layer 14 maintain an initial small tilt angle, and the first liquid crystal cell 10 is in a wide viewing angle mode.
When a large voltage difference (e.g., a voltage difference greater than 2V) exists between the first electrode 12 and the second electrode 16, a strong vertical electric field E is generated in the first liquid crystal layer 14. Since the positive liquid crystal molecules are deflected in a direction parallel to the electric field lines under the action of the electric field, the positive liquid crystal molecules are deflected under the action of the vertical electric field E to increase the tilt angle, so that the first liquid crystal cell 10 has oblique viewing light leakage, the contrast is reduced in the oblique viewing direction, the viewing angle is narrowed, and at this time, the first liquid crystal cell 10 is in a narrow viewing angle mode. As the voltage difference between the first electrode 12 and the second electrode 16 increases, the stronger the vertical electric field E generated in the first liquid crystal cell 10, the larger the tilt angle of the positive liquid crystal molecules with respect to the first substrate 11 and the second substrate 17, and the narrower the viewing angle of the first liquid crystal cell 10 becomes.
In other embodiments, the liquid crystal molecules 141 can also be negative liquid crystal molecules, and the detailed principles are disclosed in the prior art and are not described herein again.

The strength of the first liquid crystal cell 10 can be increased by providing the first columnar spacer. The first columnar spacer is a photoreactive material, so-called photoresist material, which can be divided into positive photoresist and negative photoresist according to different photoreaction mechanisms, and the first columnar spacer is obtained by directly coating the photoresist material on a transparent substrate by photolithography (Photo lithography) and performing exposure, development, baking, etc.
In this embodiment, the first retaining wall 19 is connected to a plurality of first columnar spacers.
In the liquid crystal display panel disclosed in this embodiment, a reactive liquid crystal monomer is added into the first liquid crystal layer, and ultraviolet light is irradiated to the reactive liquid crystal monomer of the first liquid crystal layer, so that the reactive liquid crystal monomer is polymerized on the surface of the opposite side of the first alignment layer and the second alignment layer to form a plurality of first retaining walls continuously arranged along the row direction and/or the column direction. The first retaining wall can effectively control the flowing speed of liquid crystal molecules in the first liquid crystal layer in the first liquid crystal box, reduce the probability of gravity Mura, increase LC Margin, effectively improve the product quality, simultaneously need not to increase the manufacture procedure of extra manufacturing obstacles, greatly reduce the manufacture cost and have higher practicability.

Specifically, the method comprises the following steps: referring to fig. 1 to 3, when the first liquid crystal cell is not irradiated with ultraviolet light UV, the liquid crystal molecules in the first liquid crystal layer and the reactive type liquid crystal monomer 142 are intermingled and mixed. After the ultraviolet light UV irradiates the first liquid crystal layer 14 through the transparent patterns 110 of the first mask 100, the reactive liquid crystal monomers 142 corresponding to the transparent patterns 110 are polymerized on the surfaces of the opposite sides of the first alignment layer 13 and the second alignment layer 15 to form the first retaining walls 19.
The liquid crystal display panel disclosed in this embodiment controls the graph of the first retaining wall by changing the transparent pattern of the first mask plate, so that the first retaining wall can effectively control the flow speed of the liquid crystal molecules 141 in the first liquid crystal layer in the first liquid crystal box 10, reduce the occurrence probability of gravity Mura, increase LC Margin, effectively improve the product quality, and meanwhile, the manufacturing process of extra manufacturing obstacles is not needed to be increased, the manufacturing cost is greatly reduced, and the liquid crystal display panel has higher practicability.
