Description of the Invention: [Technical Field of the Invention] The present invention relates to a liquid crystal (LiquidCrystal) panel structure, in particular, a 矽-based liquid crystal (four) cannon designed with a partition wall (duai spacer waU). Coffee 'LCoS) display panel structure and its manufacturing method, with a smaller 'single single wafer area, can reduce the glue width and liquid crystal loss, no need to reserve liquid crystal injection port (with drop injection technology) and no need to spray on the enamel substrate Ball spacers and many other advantages. • [Prior Art] Shi Xiji liquid crystal microdisplay is the key technology of reflective LC〇s projector and rear projection television (rear_pr〇jecti〇nteievisi〇n). The biggest advantage of LCoS microdisplays is that they can significantly reduce panel production cost, small size, high resolution and low power. Different from the thin film transistor-liquid crystal display (TFT-LCD), the upper and lower sides of the TFT-LCD are made of glass as a substrate, but LC〇s only - The substrate underneath the glass is based on semiconductor materials. Therefore, the LC〇s process is a combination of LCD and semiconductor complementary semiconductor-xide semiconductor (CMOS) processes. Please refer to FIG. 1 and FIG. 2 , wherein FIG. 1 is a top view of a conventional germanium-based liquid crystal display panel 10, and FIG. 2 is a tangent-based liquid crystal display panel 1 in FIG. Schematic diagram of the section. As shown in Fig. 1 and Fig. 2, the conventional 矽 base liquid 6 1329217 surface (four) 咐 material (four), the _ main secret domain 4 is provided with an array of arsenic electrodes (not shown), - The front panel of the glass is set in parallel; the upper layer of the moonlight board 12 is filled with the liquid crystal layer 18 on the stone backing plate η and the glass front plate% b 1 in addition to the plurality of stone slabs 12 and the glass front plate 16 Spherical spacer 22. The 'backplane 丨 2 includes a plurality of fine semiconductor semiconductor MOS devices for driving the respective halogen electrodes, and the longer sides of the tree back plate 12 are usually provided with a plurality of metal bonding pads ( Bondingp_22. In order to obtain the lack of quality, the thickness of the liquid crystal layer 18, or the gap (4) gap), that is, the transparent conductive button and the semi-conducting county paste must be precisely controlled at the solid value. In the process of the conventional liquid crystal display panel device, in order to maintain the gap, plastic beads (four) coffee bead or glass beads are placed between the upper and lower substrates as the ball type spacers 22. Therefore, the gap size is determined by the diameter of the spherical spacer. In the conventional process, the spherical spacer 22 is dispersed on the Shi Xi•back plate 12 in the manner of spraying spray. However, if the spray is unevenly distributed, where the spherical spacers are clustered, The display quality is significantly degraded and may also result in inconsistent gap sizes of the substrates. In addition, the use of plastic beads or glass beads as a spacer is also costly. In addition, the conventional method of applying the liquid crystal display panel 10 is to first apply a plastic frame 20 around the active area 14 of the back cover 12, and the width of the plastic frame is about 2 micrometers (μπι). At the time of the frame 20, a liquid crystal injection port (not shown) is reserved, and the visibility of the liquid crystal injection port is about 500 micrometers. Therefore, the area of the conventional liquid crystal display panel is relatively large. Moreover, the practice of the Shishiji liquid crystal display panel 10 generally consumes a portion of the liquid crystal when the subsequent vacuum 13292.17 sucks the liquid crystal, and the lost liquid crystal cannot be recycled, which is also the reason why the panel cost cannot be reduced. One. Moreover, after the liquid crystal is injected, the liquid crystal may react with the contacted plastic frame 20, causing contamination or deterioration of the liquid crystal. It can be seen from the above that the structure and practice of the conventional liquid crystal display panel 10 are not perfect, and there is still room for further improvement. The object of the present invention is to further integrate the LC〇s display process to effectively improve the yield and reduce the production. cost. SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide a novel structure and a manufacturing method of a Shiyake-based liquid crystal display panel to solve the above-mentioned problems of the prior art.

The present invention further discloses a method for manufacturing a liquid crystal panel, and the package 13292.17 comprises the steps of: providing a --substrate on which a display active region is formed; and a chemical on the surface of the first substrate The vapor deposition method forms a dielectric layer; using a lithography and a surname process, a portion of the dielectric layer is removed, exposing the display main-moving region' and forming a height scale-interval in the _shirt region a wall and an outer partition wall' and a gap between the inner partition wall and the outer partition wall; a glue is applied in the seal groove; _ a person is injected (0_ a process in which a plurality of liquid crystals are inserted into the __, and the second substrate is covered on the first plate of the first plate, so that the second substrate contacts the sealant, and the second substrate is aged Lai Qiqi obtains a branch; and cures the sealant. In order to enable the examiner to further understand the features and techniques of the present invention, please refer to the following detailed description and drawings relating to the present invention. However, the drawings are for reference only and are not intended to limit the invention. [Embodiment] Please refer to FIG. 3 and FIG. 4, wherein FIG. 3 is a top view of the Shiyake liquid crystal display panel 50 according to a preferred embodiment of the present invention. FIG. 4 is the third embodiment of the present invention. Schematic diagram of the XI XI LCD panel 50 along the tangential line ΙΙ-ΙΙ. The Shihki liquid crystal display panel 50 of the present invention comprises a stone back plate 52, which is provided with a display active area (display active - regi〇n) 54 A plurality of matrix electrodes (not shown) arranged in an array, a glass 13292.17 glass front plate 56 are disposed in parallel above the chopping plate 52, and a liquid crystal layer 58 is filled between the back plate 52 and the glass front plate 56. The t-back plate 52 includes a plurality of metal oxide semiconductor (MOS) devices fabricated by standard semiconductor processes for driving the respective pixel electrodes. The main technical feature of the present invention is that the active region 54 of the back plate 52 is formed around Double spacer wall ('丨 spacerr wall) design, in which the inner partition wall (such as ^ spacer _ 丨) 62 is approximately equal to the height of the outer partition wall (〇1^^& 〇£^), and the inner partition wall There is a groove 66 between the 62# and the outer partition wall 64, which can be used to accommodate the sealant 7〇 And increasing the contact area of the backing plate 52 with the sealant 70. The inner partition wall 62 and the outer partition wall 64 respectively have a flat upper surface 62a and 64a. In addition, for connecting the inner integrated circuit of the panel and the external carrier circuit The plurality of metal bond pads 522 are no longer disposed on the longer sides of the back cover 52 and are instead disposed on the shorter sides of the back cover 52. According to the present invention, the inner partition wall 62 and the outer partition wall The 64 series utilizes a semiconductor process at the end of the manufacturing process of the back plate 52, such as a chemical vapor deposition candle (10) (f) vap〇r deposition 'CVD process, chemical mechanical polishing (chemicai mechanjcai contact, CMP) process, lithography Techniques such as (iith〇graphy) and etching are defined around the display active area 54. According to a preferred embodiment of the present invention, both the inner partition wall 62 and the outer spacer 64 are composed of a dielectric material such as dioxygen (10), but this is not earned. In the present invention, the double partition wall structure composed of the inner partition wall 62 and the outer partition wall 64 serves as a support between the moon plate 52 and the glass front plate 56, since the inner partition wall 62 and the outer wall 64 are made by a semiconductor process. Therefore, its height error range is very small, 13292.17, which can precisely control and define the gap between the stone back plate 52 and the glass front plate brother. Therefore, it is no longer necessary to use plastic beads or glass beads in the conventional technique. For the spacer, you can also listen to the knowledge of the art. The dog is evenly distributed. The scales are in the cluster of the spacers, and the quality is not degraded, and the size of the base is not inconsistent. i The invention can save the cost of using plastic beads or glass beads as a medium. However, the width of the partition wall structure of the present invention is that the width of the _7() can be reduced from about 2 micrometers (four) to about 5 micrometers, so that the size can be reduced. - The area of the panel, resulting in an increase in the number of panels produced per wafer. Please refer to FIG. 5 to FIG. 9 for a schematic cross-sectional view showing a method of fabricating a bismuth-based liquid crystal panel according to an embodiment of the present invention. As shown in FIG. 5, a surface of the substrate ii has a display active region 154'. The active region 154 includes a plurality of electrodes, a plurality of electrodes electrically connected to the control circuit, and a metal mirror. The figure is not shown). The control circuit includes a plurality of arrayed transistors, such as M〇s transistors, for controlling and driving the plurality of electrodes. After the fabrication of the display active region 154 is completed, a layer of germanium dioxide 112 is deposited on the surface of the germanium substrate 152 by a chemical vapor deposition process, and then a photoresist mask pattern 114 is formed on the germanium dioxide layer 112. The shape and location of the double spacer walls to be formed in the dioxide layer 112 are defined. A protective layer or an alignment film (not shown) may be preliminarily deposited on the surface of the germanium substrate 152 before depositing the germanium dioxide layer U2. 13292.17 As shown in FIG. 6, the dioxing layer 112 not covered by the photoresist mask 114 is removed by using a photoresist engraving process with a photoresist mask ι 4 as a silver 2 hard mask until the lithium substrate 152 is exposed. The wire 'is thus formed to surround the double partition wall structure 16G' around the display active area 154 including the inner wall 162 and the outer partition wall 164. Then, • Remove the photoresist mask ugly 114 again. In accordance with a preferred embodiment of the present invention, the inner partition wall 162 and the outer partition wall (6) are continuous elongated projection structures that surround the periphery of the display active region 154 without fracture or sigma. In this way, the contact area between the sealant and the liquid crystal can be minimized by the inner spacer _wall 162, and even the complete blockage avoids the possibility of contamination or deterioration of the liquid crystal. And as mentioned above, since the inner partition wall 162 and the outer partition wall 164 are made by a semiconductor process, the squeaky smear is often small, and the rider controls and defines between the silk plate 152 and the glass front plate. Clearance. Between the inner partition wall 162 and the outer partition wall 164 is a groove 166 for accommodating the sealant and increasing the contact area between the stone back plate 110 and the sealant. Subsequently, as shown in Fig. 7, performing a drip-injection (〇nediOpfiii, a 〇阳process. The so-called (four) process system, in the process of crystallization, first forming a _off partition wall 162 in the frame of the Shixi base 110 A few drops of liquid crystal 158, in order to replace the conventional technique of vacuum filling (vae_suetio咐 liquid crystal filling. Dropping (GDF) process has the advantage of (four) Wei Jing material, (four) free of the silk screen display method in the follow-up When the liquid crystal is vacuum-injected, the flowing liquid crystal cannot be caused by the problem. Please refer to Fig. 8, and then apply the coating in the groove 66 between the partition wall 162 and the outer partition wall 164 in a vacuum environment or a low pressure. The sealant is 17 〇, wherein the sealant has a volume slightly larger than the volume of the groove 丨 66. According to a preferred embodiment of the invention, the sealant 17 〇 may be a photo-curing sealant or a heat-curing sealant material. A glass front plate 156 is disposed in parallel above the back cover plate 152, and the glass front plate 156 and the base plate 152 are bonded together by the sealant 170, as shown in Fig. 9. Then, a curing process is performed, Irradiated with ultraviolet light or heated In the formula, the sealant 170 is hardened. Incidentally, the fabrication of the liquid crystal based panel of the present invention is performed under wafer scale, and the liquid crystal is dropped (0DF) technology before the wafer is cut. On the surface of the ruthenium substrate, the glass is then combined with the shixi substrate by a sealant, and then the dicing process is performed to form each panel. Compared with the prior art, each gossip wafer can only produce about 89. The panel wafer, the invention adopts a double partition wall design, and the bonding pad is disposed on the shorter side of the panel, so that the productivity of each gossip wafer can be significantly improved (only about 150 wafers per wafer) The panel wafer), together with the drop-injection (〇DF) process, can save a lot of manufacturing costs.
