Description

Liquid crystal display panel and manufacturing method thereof

technical field

The present invention relates to a liquid crystal display panel and a manufacturing method thereof, and in particular to a liquid crystal display panel using polymer stable alignment technology and a manufacturing method thereof.

Background technique

At present, in liquid crystal display panel technology, the technologies that can meet the requirements of wide viewing angle include twist nematic (TN) liquid crystal plus wide viewing film (wide viewing film), in-plane switching (IPS) ) liquid crystal display panel, fringe field switching (fringe field switching) liquid crystal display panel, multi-domain vertical alignment (multi-domain vertically aligned, MVA) liquid crystal display panel, etc. Among these technologies, the multi-domain vertical alignment liquid crystal display panel has been widely used in various electronic products.

The existing multi-domain vertical alignment type liquid crystal display panel utilizes the configuration of the alignment structure to make the liquid crystal molecules in different regions tilt at different angles, so as to achieve the effect of wide viewing angle. However, the design of the multi-domain vertical alignment liquid crystal display panel still has the problem of poor display contrast. Therefore, a polymer-stablized alignment (PSA) type liquid crystal display panel, which uses a polymer-stabilized alignment process to form a multi-domain alignment alignment method, is proposed.

The polymer stabilized alignment process requires doping reactive monomers into the liquid crystal layer and applying a specific electric field to the liquid crystal layer. When the liquid crystal layer is irradiated with a light or a heat source under the electric field, the reactive monomers will be polymerized and solidified to form polymer stabilized alignment layers on the substrates on both sides of the liquid crystal layer. Among them, the polymer stabilizes the molecules of the alignment layer to present a specific structure, which helps to make the liquid crystal molecules tilt and align in different directions, and achieve a wide viewing angle display effect.

In addition, in order to improve the alignment effect of liquid crystal molecules, the polymer stabilized alignment type liquid crystal display panel also forms micro slits on the pixel electrodes or makes alignment protrusions on the substrate. However, the micro slits on the pixel electrodes will cause the loss of pixel display brightness and affect the display quality. On the other hand, the disposition of the alignment protrusions will discontinuously tilt the direction of liquid crystal molecules located around the alignment protrusions, resulting in light leakage. In this way, the display contrast of the liquid crystal display panel will be reduced, and the extra fabrication of alignment bumps will also cause a burden on the manufacturing process and affect the yield of the manufacturing process.

Please refer to FIG. 1 and FIG. 2A first. The manufacturing method of the liquid crystal display panel 100 of the present invention, for example, firstly provides a panel 100'. The panel 100' includes a first substrate 110, a second substrate 130 and a liquid crystal layer 150. The first substrate 110 has an active device array 110'. The second substrate 130 has a pair of opposite electrodes 132 . The liquid crystal layer 150 is located between the first substrate 110 and the second substrate 130 , and the liquid crystal layer 150 has a plurality of liquid crystal molecules 152 and a polymerizable monomer material 154 .

In detail, the first substrate 110 has a plurality of scanning lines 112 and a plurality of data lines 114, only one scanning line 112 and two data lines 114 are shown in FIG. 1 to clearly represent each component. come out. The scan wires 112 respectively intersect with the data wires 114 to define a plurality of pixel regions P arranged in matrix on the first substrate 110 . The first substrate 110 in each pixel area P also has an active device 116 , a pixel electrode 118 , an auxiliary electrode 120 and a shielding electrode 122 . The active component 116 is coupled to the corresponding scan wiring 112 and the data wiring 114 , and the pixel electrode 118 is coupled to the active component 116 . The auxiliary electrode 120 is located on the pixel electrode 118 and coupled to the pixel electrode 118 , and the shielding electrode 122 is located on the periphery of the pixel electrode 118 and surrounds the auxiliary electrode 120 . It is worth mentioning that the shielding electrode 122 can be used as a capacitor electrode in the liquid crystal display panel 100 , and the shielding electrode 122 and the pixel electrode 118 form a storage capacitor to maintain the display voltage of the pixel electrode 118 .

Next, please refer to FIG. 1 and FIG. 2B at the same time, apply a first curing voltage Vcur1 (or called scanning line curing voltage) to the scan wiring 112, and apply a second curing voltage Vcur2 (or called scanning line curing voltage) to the data wiring 114. data line curing voltage). In addition, the opposing potential of the opposing electrode 132 and the shielding electrode 122 includes a ground potential or a fixed potential. Under such conditions, the second curing voltage Vcur2 is applied to the pixel electrode 118, and an electric field E is generated in the liquid crystal layer 150, so that the liquid crystal molecules 152 are aligned along a pretilt angle.

In this embodiment, the first curing voltage Vcur1 is substantially greater than the absolute value of the second curing voltage Vcur2. Specifically, when the electric field E is applied to the liquid crystal layer 150 , the voltage difference between the pixel electrode 118 and the counter electrode 132 is, for example, between 5V and 40V. In addition, in this process step, the voltage difference between the first curing voltage Vcur1 and the second curing voltage Vcur2 is, for example, greater than the initial voltage of the active device 116 . In practice, the voltage difference between the first curing voltage Vcur1 and the second curing voltage Vcur2 is, for example, greater than 7V so that the second curing voltage Vcur2 can be passed into the pixel electrode 118 smoothly.

In detail, please refer to FIG. 2A and FIG. 2B at the same time. The method of polymerizing the monomer material 154 in the liquid crystal layer 150 includes irradiating the monomer material 154 with light, such as irradiating ultraviolet light. The light power for the monomer material 154 is, for example, between 50 mW and 1000 mW. In addition, the irradiation time for the monomer material 154 may be between 50 seconds and 500 seconds. In practice, in the step of illuminating the monomer material 154 , the illumination power and illumination time can be adjusted and matched with different process requirements, and the present invention is not limited to the above numerical range. In addition, this embodiment takes the light-reactive monomer material 154 as an example for illustration. When the monomer material 154 is a heat-reactive material or other materials, other methods should be used to polymerize the monomer material 154 .

The manufacturing method of this embodiment is to polymerize the monomer material 154 in the liquid crystal layer 150 under the action of light to form a polymer layer on the inner surfaces of the first substrate 110 and the second substrate 130 . In this way, a first polymer stable alignment layer 162 can be formed between the first substrate 110 and the liquid crystal layer 150 , and a second polymer stable alignment layer 164 can be formed between the second substrate 130 and the liquid crystal layer 150 , where Figure 2B is only for schematic representation. Then, the electric field is removed to complete the liquid crystal display panel 100 .

In the first substrate 110 of this embodiment, the auxiliary electrodes 120 disposed above the pixel electrodes 118 and the pixel electrodes 118 belong to different film layers and are disposed on different planes. Therefore, when the pixel electrode 118 is supplied with the second curing voltage Vcur2, the edge of the auxiliary electrode 120 will generate a marginal electric field effect. In addition, the shielding electrode 122 surrounding the auxiliary electrode 120 will also generate a marginal electric field effect at the edge of the pixel electrode 118 . Therefore, in each pixel area P, the distribution of the electric field E is not uniform.

Under the effect of the fringe electric field provided by the auxiliary electrode 120 and the shielding electrode 122 , the liquid crystal molecules 152 will be arranged in a specific way, such as the state shown in FIG. 2B . In other words, under the structural design of the first substrate 100 , when the pixel electrode 118 is supplied with the second curing voltage Vcur2 , the liquid crystal molecules 152 at different positions will be arranged along different pretilt angles. At this time, the arrangement of the liquid crystal molecules 152 will affect the polymerization process of the monomer material 154 . Therefore, the arrangement of polymers in the first polymer stabilized alignment layer 162 and the second polymer stabilized alignment layer 164 has specific structural features, for example. In the present invention, directly applying the second curing voltage Vcur2 to the pixel electrode 118 can provide a more stable and accurate liquid crystal alignment effect than using a common electrode to couple the curing voltage of the pixel electrode 118 .

After the electric field E is removed, the specific structural features of the first polymer stabilized alignment layer 162 and the second polymer stabilized alignment layer 164 can provide a certain alignment anchoring force to help improve the response rate of the liquid crystal molecules 152 . That is to say, in this embodiment, the polymer stable alignment process can be performed without the design of the micro-slits or micro-protrusions to form the multi-domain alignment liquid crystal display panel 100 and provide a more stable alignment effect. Therefore, in the liquid crystal display panel 100 manufactured according to the above manufacturing process, the response rate of the liquid crystal molecules 152 is good, and the display quality of the liquid crystal display 100 can be further improved without being affected by the micro slits or alignment bumps.

In this embodiment, the pixel electrode 118 is completely disposed in the pixel region P, so when the liquid crystal display panel 100 displays a picture, the liquid crystal molecules in the entire pixel region P can display. Compared with the existing design in which the liquid crystal molecules above the micro slits cannot display, the liquid crystal display panel 100 has better display brightness. In addition, in order to make the liquid crystal display panel 100 present a colorful display effect, the first substrate 110 or the second substrate 130 may further have a plurality of color filter units, which are respectively located in the corresponding pixel regions P. That is, the second substrate 130 may be a color filter substrate or the first substrate 110 may be a color filter layer fabricated on a pixel array (Color filter on Array, COA) or a pixel array fabricated on a color filter layer ( Array on Color filter, AOC) design.

It is worth mentioning that the manufacturing method of this embodiment is not limited to be applied in the liquid crystal display panel 100 shown in FIG. 1 . In other embodiments, the above manufacturing method can also be applied to a liquid crystal display panel without the design of the auxiliary electrode 120 and the shielding electrode 122 . In addition, as can be seen from FIG. 2B, from the perspective of the stacking order of the metal film layers, in the liquid crystal display panel 100, the data wiring 114 is made of the first metal layer directly arranged on the substrate, and the scanning wiring 114 112 is made by disposing the second metal layer on the insulating layer. Meanwhile, the auxiliary electrode 120 and the shielding electrode 122 are made of the third metal layer. However, the present invention is not limited thereto. In other implementations, the data wiring 114 and the scanning wiring 112 can also be made of the second metal layer and the first metal layer respectively.

3A and 3B are respectively a schematic top view and a partial cross-sectional view of the first substrate of a liquid crystal display panel according to another embodiment of the present invention, wherein FIG. 3B is shown along the section lines DD' and EE' in FIG. 3A sectional view. Please refer to FIG. 3A and FIG. 3B at the same time. The first substrate 300 has a plurality of scanning wires 310 and a plurality of data wires 320 , and FIG. 3A takes two as an example. The scan wires 310 respectively intersect with the data wires 320 to define a plurality of pixel regions P on the first substrate 300 . In addition, the first substrate 300 in each pixel region P further has an active device 330 , a pixel electrode 340 , two auxiliary electrodes 350 and a shielding electrode 360 . The coupling relationship of the above components is, for example, the same as that of the components of the first substrate 110 in the previous embodiment. In addition, both auxiliary electrodes 350 are surrounded by a shielding electrode 360 .

In the first substrate 300, when the design of the two auxiliary electrodes 350 is applied to the liquid crystal display panel, the liquid crystal molecules in the liquid crystal display panel can be arranged along more multi-alignment domains. That is to say, the design of the first substrate 300 can further enhance the display effect of the liquid crystal display panel with a wide viewing angle. In addition, in order to match the design of the two auxiliary electrodes 350 , the shielding electrode 360 of this embodiment presents a "day"-shaped design, for example.

Specifically, from the cross-sectional view of FIG. 3B , the scan wiring 310 is made of the first metal layer in this embodiment, the data wiring 320 is made of the second metal layer, and the auxiliary The electrode 350 and the shielding electrode 360 are both made of the third metal layer. In other words, the process sequence of the first substrate 300 is different from the above-mentioned process sequence of the first substrate 110 .

In addition, in the first substrate 300 , the auxiliary electrode 350 and the pixel electrode 340 belong to different film layers and are located on different planes. Therefore, when the pixel electrode 340 is input with a voltage, a marginal electric field effect will be generated between the auxiliary electrode 350 and the pixel electrode 340 . Similarly, a corresponding fringe electric field effect will also be generated between the shielding electrode 360 and the pixel electrode 340 . Therefore, when the first substrate 300 is applied to the manufacturing method of the liquid crystal display panel of the foregoing embodiments, it is helpful to make the liquid crystal layer in the liquid crystal display panel exhibit multi-domain alignment. That is to say, when the first substrate 300 is applied in the aforementioned manufacturing method, it is helpful to increase the response rate of the liquid crystal molecules of the liquid crystal display panel and improve the display quality of the liquid crystal display panel.

To sum up, in the present invention, different curing voltages are respectively input into the scanning wiring and the data wiring, and the curing voltage is directly provided to the pixel electrodes, so as to stabilize the polymer alignment of the liquid crystal display panel without micro-slits and alignment protrusions. Process.
