Abstract

A liquid crystal display panel and a method for fabricating the same are provided. The liquid crystal display panel comprises an active device array, a front substrate, at least one first spacer, and a liquid crystal layer. Wherein, the front substrate is disposed over the active device array. The first spacer is disposed between the front substrate and the active device array, and is partially embedded into an opening formed on the active device array. In addition, the liquid crystal layer is disposed between the front substrate and the active device array. Since the first spacer is embedded into the opening, the misalignment between the front substrate and the active device array can be effectively prevented, and the abnormal display due to the misalignment causing by external force can therefore be prevented.

FIG. 1 is a schematic cross-sectional view of a conventional liquid crystal display panel. Referring to Fig. 1, the liquid crystal display panel 100 is composed of a lower substrate 110, a liquid crystal layer 120, and an upper substrate 13A. The liquid crystal layer 120 is sealed between the lower substrate 110 and the upper substrate 130 by a sealant (not shown). In addition, various performances of the liquid crystal display, such as response speed, contrast value, and viewing angle, are related to the hole spacing d. Therefore, the crystal hole pitch d is generally controlled in accordance with the optical characteristics of the liquid crystal material. In addition, if the inter-cell spacing d has a different value, it is easy to cause uneven display, and the visibility of the image will be remarkably lowered. Therefore, a spacer 102 is usually disposed between the lower substrate 11A and the upper substrate 13A to maintain the cell spacing d constant. In the current technology, the spacers 1〇2 are mostly formed on the upper substrate 13〇 in the process of the upper substrate 130, and thus the spacer 1〇2 is referred to as SOC (spacer on c〇l〇r Fiiter). In addition, since the spacers 102 5 1269920 15668twf.doc/g are in complete contact with the contact surface of the lower substrate 110, there is no fixing layer therebetween, and therefore, when the liquid crystal display panel 100 is subjected to the applied lateral force F, It is easy to cause the upper substrate 130 and the lower substrate 110 to be relatively misaligned, thereby generating an abnormal image display. SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a liquid crystal display panel having a relatively uniform cell gap. Another object of the present invention is to provide a method of fabricating a liquid crystal display panel to increase the liquid crystal margin and to avoid light leakage caused by the misalignment of the two substrates after the liquid crystal display panel is assembled. The invention provides a liquid crystal display panel, which is mainly composed of an active device array, a front substrate, at least a first spacer and a liquid crystal layer. The active device array is mainly composed of a substrate, a plurality of scanning wires, a plurality of data wires, a plurality of active components, and a plurality of halogen electrodes. The data wiring system and the scanning wiring distinguish a plurality of halogen regions on the substrate, and the data wiring and/or the scanning wiring system have at least one opening. These active components are arranged in the above-mentioned halogen regions to lightly connect to the corresponding broom wiring and data wiring. The above-described halogen electrodes are also disposed in these pixel regions respectively to engage the corresponding active elements. As described above, the front substrate is disposed above the active device array. The first spacer is disposed between the front substrate and the active device array, and the first spacer is partially intended to be inserted into the opening. The liquid crystal layer is disposed between the = column and the front substrate. In a preferred embodiment of the present invention, the liquid crystal display panel further includes a second spacer </ RTI> disposed between the front substrate and the broom wiring and/or the data line. . Further, in the example, the first spacer and the second spacer described above are, for example, column spacers. In a preferred embodiment of the invention, the depth of the opening is, for example, less than the maximum amount of elastic deformation of the second spacer. In one example, the depth of the opening is, for example, less than 〇·25 μm. In the present invention, preferably, the bottom area of the opening π is greater than or equal to 2/3 of the area of the first spacer contacting the front substrate. In a preferred embodiment of the invention, the front substrate is, for example, a color filter. Further, the active element described above is, for example, a thin film transistor. The invention provides a method for manufacturing a liquid crystal display panel, which first provides an active device array, which is composed of a substrate, a plurality of brooms, wires, a plurality of data wires, a plurality of active components, and a plurality of cymbals. It consists of a prime electrode. Wherein, the data wiring and/or the scanning wiring system has at least one opening i, and the data wiring and the scanning wiring system distinguish a plurality of halogen regions on the substrate, and (4) the silk element and the four-electrode element are respectively disposed on These are all within the prime area. According to the above, at least one first spacer and at least one second spacer are formed on a front substrate, and on the other hand, a liquid crystal layer is formed on the active device array. Thereafter, the front substrate is attached over the active device array such that the first spacer is partially embedded in the opening. In a preferred embodiment of the present invention, before forming the liquid crystal layer, a mask glue is formed on the substrate to surround the liquid crystal layer to cause the liquid crystal layer to be on the array of the movable elements. 7 1269920 15668twf.doc/g In a preferred embodiment of the present invention, the method of bonding the front substrate to the active device array is, for example, first disposing the front substrate on the active device array; 2) the spacer corresponding to the opening . Then, the active component is merged with the rigid substrate, and then the sealant is cured to fix the front substrate above the active second and the soil. Among them, the method of curing the sealant is, for example, a heat curing method or a 疋 ultraviolet curing method. The thunder is used to implement the object, and the active device is an array of thin films, and the front substrate is, for example, a color filter. In addition, in the other two embodiments, the active device array is a laminated color filter array, and the front substrate is composed of a substrate and a common electrode disposed thereon. The present invention is used to form a scan wiring and In the process of data wiring, f is formed with an opening thereon, so that after the liquid crystal display panel is assembled, the first spacer disposed on the board may be partially embedded in the opening. Therefore, the lateral force of the substrate iff is not misaligned with the wire element array. It can be seen that the present invention can display images without causing the above-mentioned and other objects, features and advantages of the present invention to be improved by the fact that the number of masks is increased without the number of masks being misaligned. The special case is better _, and with the following:, as clearly as follows.丨F Ping condition [Embodiment] FIG. 2 is a view showing a liquid crystal display panel in a preferred embodiment of the present invention. FIG. 3 is a partial view of the active device array 210 of FIG. 2 1269920 15668twf.doc/g. Referring to FIG. 2 and FIG. 3 simultaneously, the liquid crystal display panel 2 is mainly composed of an active device array 21A, a front substrate 22A, a first spacer 2〇2, and a liquid crystal layer 230. The active device array 21 is, for example, a thin film transistor array (TFT array), which is composed of a substrate 212, a plurality of scan lines 214, a plurality of data lines 216, a plurality of active elements 218, and a plurality of The pixel electrodes 219 are formed. The scan wiring 214 and the data wiring 216 are disposed on the substrate 212, and a plurality of halogen regions 217 are distinguished on the substrate 212. 2 and 3, the data wiring 216 has an opening 204, which is formed, for example, in the same process as the data wiring 216. In particular, the distance between the opening 204 and the halogen electrode 219 is, for example, greater than 3 μm to avoid affecting the aperture ratio of the liquid crystal display panel 2 . In addition, the active component 218 is, for example, a thin film transistor, and each of the active components 218 is disposed in a pixel region 217 and coupled to the corresponding scan wiring 214 and data wiring 216. The halogen electrode 219 is also disposed in the halogen region 217 and is lightly connected to the corresponding active element 8. The uranium substrate 220 is disposed above the active device array 21A. In this embodiment, the front substrate 220 is, for example, a color filter, which is mainly composed of a plurality of color filter films (c〇1〇r mtermm) 224 of the substrate 22 (only FIG. 2 is drawn) One), a black matrix (BM) 226, and a common electrode 228. The color filter film 224 and the black matrix 226 are disposed on the substrate 221, and the common electrode 228 covers the color filter film 224 and the black matrix 226. Referring to Fig. 2, the first spacer 202 is disposed between the front substrate 220 9 1269920 15668 twf.doc/g ^ array 210, and the first spacer 202 is partially embedded in the strict 幵口. It is worth mentioning that, because the column spacers and the spherical spacers under the 'column spacers can provide a more uniform gap of the liquid crystal display panel, better light transmittance and higher In contrast, in this embodiment, for example, the first spacer is discarded as a column spacer to reach the above point. More specifically, the bottom area of the opening 2〇4 is, for example, greater than or equal to 2/3 of the contact area of the first spacer 202 and the front substrate 220 in order to effectively embed the first spacer 202. As can be seen from the above, the liquid crystal display panel 200 of the present invention is designed such that the first spacer 202 is partially embedded in the opening 2〇4 in the place where the aperture ratio is not affected (that is, on the data wiring 216) to avoid liquid crystal. After the display panel 200 is subjected to an external force, the active device array 21 is misaligned with the front substrate 220, thereby generating an abnormal image display. It is to be noted that in other embodiments, the opening 204 can also be designed on the scan wiring 214, which also does not affect the aperture ratio of the liquid crystal display panel 3, as shown in FIG. Of course, the present invention can also design the opening 204 on the data wiring 216 and the scanning wiring 214 at the same time, as shown in FIG. 6 is a cross-sectional view showing a liquid crystal display panel in another preferred embodiment of the present invention. Referring to FIG. 6, the liquid crystal display panel of the present invention may further include a second spacer 206 to increase the load rigidity of the liquid crystal display panel. The second spacer 206 is disposed between the active device array 210 and the front substrate 220. In more detail, the second spacer is disposed on the front substrate 220 and the scan wiring 214 and/or the data wiring 216. between. It is noted that the second spacer 206 is not embedded in the opening 204 of the scan wiring 1269920 15668 twf. doc/g 214 and/or the data wiring 216. Moreover, those skilled in the art will appreciate that the first spacer 202 and the second spacer 206 are mostly composed of an elastic material, so that during the process of pressing the active device array 210 and the front substrate 220, the second spacer 206 will Deformation caused by external force, thereby causing a height between the first spacer 202 and the second spacer 206

Wherein, in order to avoid plastic deformation of the second spacer 206, the wafer gap uniformity of the liquid crystal display panel 7 〇 影响 is affected, and the deformation amount of the second spacer 206 must fall within the range of the elastic deformation region. That is, the depth h of the opening 204 is, for example, smaller than the maximum elastic deformation amount of the second spacer 206. For example, if the maximum amount of elastic deformation of the second spacer 206 is 〇·25 μm, the depth h of the opening 204 needs to be less than 0.25 μm. It is particularly worth mentioning that, as can be seen from the above, after the liquid crystal display panel 700 of Fig. 6 is assembled, a difference in twist between the first spacer 2〇2 and the second spacer 2〇6 is generated. Therefore, if the liquid crystal layer 23 of the liquid crystal display panel 7 is formed by the dropping type implantation method, 余df), the liquid crystal dropping margin can be increased to reduce the incidence of engineering defects. Hereinafter, a liquid crystal display surface having a height difference between spacers will be exemplified, and the active device array of the liquid crystal display panel is the same as the active device array of FIG. 3, FIG. 4 or FIG. 5, and the following assumptions are made. The liquid crystal display panel array is illustrated by the active device array of FIG. 5, but it is not intended to limit the present invention. /, 丄 is - 8 11 1269920 15668twf.doc / g is the same as the active το Array 21 图 of Figure 3, the only difference is only the scanning element of the active device array 610 of Figure 5, line 214 and The data traces 216 each have an opening 204, so the active device array 610 will not be described in detail herein. Next, referring to Fig. 7A, a first spacer 202 and a second spacer 206 are formed on the front substrate 22A. Among them, the first spacer 2〇2 and the second spacer 206 are made of, for example, an elastic material. It should be noted that the present invention is not limited to the number of the second spacer 2〇2 and the second spacer 2〇6, and those skilled in the art can make their own decisions according to actual needs. Further, the front substrate 220 is, for example, a color filter as shown in Fig. 2 . Under this assumption, the first spacer 202 and the second spacer 206 are formed over the black matrix 220 (see Fig. 2), so that the aperture ratio of the liquid crystal display panel is not affected. Then, referring to FIG. 7B, a liquid crystal layer 230 is formed on the active device array 610. It is worth mentioning that before forming the liquid crystal layer 23, the frame glue 62〇 must be formed on the active device array 610, and a liquid crystal injection region 6〇2 is enclosed on the active device array 610 (as shown in FIG. 8). Then, liquid crystal molecules 232 are injected into the liquid crystal injection region 602 by a dropping method to form the liquid crystal layer 230. In this way, the liquid crystal layer 230 can be sealed between the active device array 610 and the front substrate 220 in a subsequent process. Referring to FIG. 7C', the front substrate 220 is disposed above the active device array 610 such that the first spacers 202 correspond to the openings 204 on the active device array 610. Then, the front substrate 220 and the active device array 610 are pressed to partially embed the first spacer 202 in the opening 204 as shown in Fig. 7D. At this time, the second spacer 206 has a deformation amount which is the depth h of the opening 204. As explained in the foregoing embodiment, the depth h of the opening 204 8 12 1269920 15668 twf.doc/g is, for example, smaller than the maximum elastic deformation amount of the second spacer 206. In particular, since the active element array 61 is assembled with the front substrate 220 and has a height difference between the first spacer 202 and the second spacer 206, the present invention can increase the dropping margin of the liquid crystal molecules 232 so that In response to the needs of different models, and thus improve the process yield. Taking a 2-inch liquid crystal display panel as an example, an active device array 61 having an opening of 2 〇 4, for example, can increase the liquid crystal margin by 20%. Thereafter, the sealant 620 of FIG. 7D is cured to fix the relative positions of the active device array 610 and the front substrate 220, which completes the assembly of the liquid crystal display panel 8A. The 'frame glue 620 is, for example, a thermal curing frame glue or a UV curing frame glue, and the method for curing the frame glue 620 is a heat curing method and an ultraviolet curing method according to the characteristics of the frame glue. law. In addition, the subsequent processes of the liquid crystal display panel 800 are as known to those skilled in the art, and will not be described herein. In summary, the present invention has the following advantages: 1. The present invention forms an opening on the active device array to enable liquid crystal display. After the panel is not assembled, the first spacer disposed on the front substrate can be partially embedded. Inside the opening. Therefore, even if the front substrate is subjected to an applied lateral force, it does not cause a misalignment with the active device array. It can be seen from the above that the present invention can avoid abnormal image display caused by misalignment of the front substrate and the active device array. 2. The opening in the active device array of the present invention is located on the scan wiring and/or the data wiring, and the opening is formed in the same process as the scan wiring and/or the data wiring. In other words, the present invention does not require the addition of a reticle to form an opening in the array of active elements on the 8 13 1269920 15668 twf.doc/g. 3. The present invention arranges a first spacer corresponding to the opening of the active device array and a second spacer not corresponding to the opening on the front substrate, thereby increasing the load rigidity of the liquid crystal display panel. Moreover, after the front substrate and the active element are assembled, a height difference will be generated between the first spacer and the second spacer, which can increase the margin in the process of liquid crystal dropping, so that the furnace can be adapted to various different types of machines. Demand, which in turn increases process yield. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and any skilled person skilled in the art can make some modifications and retouchings without departing from the invention. According to the invention: the scope of the can is regarded as the φ which is defined by the special fiber.
