   BACKGROUND OF INVENTION 
   1. Field of Invention 
   This invention relates to a liquid crystal device and the manufacturing method thereof. Moreover, this invention particularly relates to a liquid crystal device and manufacturing method for simultaneously forming conductive and/or insulating walls using Thin Film Transistor (TFT) Deposition as well as pixel electrode therein. 
   2. Description of Prior Art 
   The present liquid crystal device process comprises forming of Thin Film Transistor (TFT), Liquid Crystal Device (LCD) panel, and liquid crystal module. Common TFT structure includes gate metal layer, semiconductor layer (wherein semiconductor layer includes gate insulating layer, amorphous crystalline layer, and a n+ doping layer), source/drain metal layer, and passivation layer. The forming of TFT process includes repeated rinsing, deposition, yellow light exposure, developing, etching, and lift-off. Take gate metal layer for example, a substrate is rinsed firstly, followed by depositing a metal layer on substrate surface, coating photoresist on the metal layer, exposed under light, developing away the unwanted pattern, etching for desired pattern, and finally lift off the photoresist to form a gate metal layer. Continue on next mask accordingly. 
   The process of forming a LCD panel mainly comprises One Drop Fill process, i.e. ODF process, as shown in  FIG. 1A . A sealant, an Ultraviolet sealant (UV sealant) for example, is applied to a substrate A 1  in an enclosed form, and liquid crystal is dropped from a liquid crystal dispenser to the enclosed area as shown in  FIG. 1B . After forming a uniform liquid crystal layer A 4 , take another substrate A 2  to bond to substrate A 1  that has the liquid crystal layer A 4 , and continue to irradiate (ultraviolet light, for example) the sealant A 3  so as to adhere the two substrates A 1  and A 2  together (as shown in  FIG. 1C ). After an annealing process, the procedure is ultimately done. 
   However, the drawback to this technique is, some part of the liquid crystal layer A 4  would be exposed to lighting when irradiating sealant A 3  in order to adhere substrates A 1  to A 2 , thus liquid crystal suffers from degradation. 
   Moreover, the liquid crystal layer A 4  that contacts with the sealant A 3  is possibly contaminated, which also down-grades display quality. 
   In order to avoid contact contamination between the liquid crystal A 4  and the sealant A 3 , the US patent U.S. Pat. No. 6,219,126 discloses a method using coating or lithography techniques for building an enclosed liquid crystal wall structure that is made of acrylic resin or silicone. Nevertheless, the structure requires excess materials and steps that complicate the process. 
   JP patent JP2001-222017 as well discloses that in order to implement liquid crystal wall equivalency, a pigment-layer of deposited CF (color filter) substrate is used (as shown in  FIG. 3 ). Yet in order to avoid liquid crystal degradation caused by ultraviolet lighting, masking effect has to be tied with pigment color as well as concentration control thereof. 
   Another prior art as shown in  FIG. 4 , a liquid crystal device comprises a TFT substrate B 1  and a Color Filter (CF) substrate B 2  in parallel with a liquid crystal layer B 3  therebetween. When TFT substrate B 1  that is voltage driven has a potential difference from CF substrate B 2 , the transmittance of the liquid crystal molecules is manipulated by voltage difference thereof. Generally, the voltage applied to CF substrate B 2  is fixed as a common voltage Vcom so as to vary voltage V applying to pixel electrode B 11  on TFT (not shown) to generate a potential difference ΔV=V−Vcom. However, there is no terminal to CF substrate B 2 , Vcom voltage has to be provided by TFT. 
   For instance, usually Vcom voltage on TFT substrate B 1  is transmitted to CF substrate B 2  through conductive adhesive B 4 , however, it has to be done outside of sealant B 5  by applying excess conductive adhesive B 4  with an excess device. Obviously there is excess material cost and as well as the process has to be done after sealant is hardened. 
   In addition, as disclosed in US patent U.S. Pat. No. 6,404,480, a conductive spacer B 6  is used to support and conduct TFT substrate B 1  and CF substrate B 2  as well as to be mixed with sealant B 5  (as shown in  FIG. 5 ), so as to perform conducting Vcom voltage. Yet conductive material is required and the process difficulty is raised and all sealant B 5  is possibly not hardened.

   DETAILED DESCRIPTION 
   First Embodiment of the Present Invention: As shown in the  FIGs. from 6A to 6F , a TFT formation process is performed on a substrate  11 . To be simplified, only single TFT is illustrated in this and the other preferred embodiments in this invention. After depositing the gate metal layer  17 , manipulate the mask  13  to at least cover the gate metal layer  17 , and as well superimpose another larger frame mask  14  on the substrate  11  simultaneously. A frame spacing  15  (as shown in top view diagram in  FIG. 6A ) is formed in between the two masks,  13  and  14 . The materials of masks  13  and  14  are those not prone to bond to metal, such as insulator, or processed material so that it does not prone to bond to metal. Notice that manipulation of masks  13  and  14  is automated. 
   As deposition is continued within the frame spacing  15  (as shown in  FIG. 6B ), an enclosed metal wall  16  is built after removal of the two masks  13  and  14  in a predetermined period of time. To accomplish the forming of the TFT (as shown in  FIG. 6C ), liquid crystal is dropped to the metal wall  16 , and to enable to form a uniform liquid crystal layer  18 . An ultraviolet sealant  19  is coated on periphery of metal wall  16  (as shown in a top view in  FIG. 6D  and a cross-sectional view in  FIG. 6E ) in order to be pre-sealed to another substrate  12 . Then use UV light hardens the UV sealant  19  so that substrates  11  and  12  are bonded. An annealing process is applied so as to accomplish a liquid crystal display panel (as illustrated in  FIG. 6F ). 
   The metal wall  16  is bonded to both the top and bottom substrates  11  and  12 , thus the liquid crystal layer  18  has no contact to UV sealant  19  so as to avoid contamination of liquid crystal that causes degradation of display quality. 
   Moreover, when UV light irradiates the UV sealant  19  to bond substrates  11  and  12  together, the formation of enclosed metal wall  16  entirely blocks UV light transmitting from either side of the two bonded substrates  11  and  12 , thus degradation of liquid crystal is avoided. 
   Furthermore, the metal wall  16  formed on the substrate  11  contacts another substrate  12  so as to conduct substrate  11  (i.e. TFT substrate) to substrate  12  (i.e. Color Filter, CF substrate), as well as supports the structure, where conductive material, e.g. conducting adhesive or conductive spacer, is not necessary. 
   Second Preferred Embodiment:  FIGS. 7A to 7F  illustrate the formation of TFT on the surface of a substrate  21 . A source/drain metal layer  27  is deposited following by manipulating a mask  23  to at least cover the source/drain metal layer  27 . Another larger frame mask  24  simultaneously superimposes on substrate  21  to form a frame spacing  25  in between the two masks  23  and  24  (as illustrated in a top view in  FIG. 7A ). Notice that the masks  23  and  24  are made of materials that do not prone to bond to metal, insulator for example, or made of processed material that does not prone to bond to metal. Furthermore, the manipulation of masks  23  and  24  is automated. 
   Deposition is continued in the frame spacing  25  (as illustrated in  FIG. 7B ) and an enclosed metal wall  26  is formed after removal of the two masks  23  and  24  so as to complete the TFT formation process (as illustrated in  FIG. 7C ). Dropping liquid crystal to the metal wall  26  and to enable to form a uniform liquid crystal layer  28  is followed by coating UV sealant  29  along periphery of the metal wall  26 . (as illustrated in a top view diagram of  FIG. 7D  and a cross-sectional view diagram of  FIG. 7E ) Another substrate  22  is then adhered and processed the UV light exposure so as to take UV sealant  29  into effect, i.e. bonding substrates  21  and  22  together. The last process step is annealing, thereof a liquid crystal display panel is completed (as illustrated in  FIG. 7F ). 
   For the metal wall  26  is bonded to the top and the bottom substrates  21  and  22 , liquid crystal layer  28  has no contact with UV sealant  29  so that contamination of liquid crystal and degradation of display quality are avoided. 
   In addition, while irradiating UV light to harden UV sealant  29  in order to bond substrates  21  and  22 , UV light is completely blocked by the bonded substrates  21  and  22  from any side, thus degradation of liquid crystal is avoided. 
   Moreover, the metal wall  26  formed on substrate  21  contacts another substrate  21  so as to simultaneously conduct substrate (TFT substrate) to substrate  22  (CF substrate) as well as supports the structure, where conducting adhesive or conducting spacer are not necessary. 
   Third Preferred Embodiment: Referring to  FIGS. 8A to 8F , a TFT forming process is performed on a substrate  31 . After depositing pixel electrode layer (Indium-Tin Oxide, ITO, for example), manipulate a mask  33  to at least cover pixel electrode layer  37 . Manipulating a larger frame mask  34  to simultaneously superimpose on substrate  31 , so as to form a frame spacing  35  between the two masks  33  and  34  (as illustrated in top view diagram in  FIG. 8A ). Notice that materials constituting masks  33  and  34  are those not prone to bond to metal, such as insulator, or processed material that does not prone to bond to metal. Also notice that manipulation of masks  33  and  34  is automated. 
   As deposition is continued, it is performed within the frame spacing  35 . As the two masks  33  and  34  is removed in a predetermined period of time, an enclosed metal wall  36  is formed and to continue TFT formation process thereof (as illustrated in  FIG. 8C ). Liquid crystal is dropped in metal wall  36  and to enable to form an uniform liquid crystal layer  38 , UV sealant  39  is further coated along metal wall  36  (as illustrated in top view diagram in  FIG. 8D  and cross-sectional diagram in  FIG. 8E ). To pre-seal with another substrate  32 , and UV sealant  39  is hardened by UV irradiation in order to bond substrates  31  and  32  together, and an annealing step is performed therein to complete a liquid crystal display panel (as illustrated in  FIG. 8F ). 
   Since metal wall  36  is bonded to substrates  31  and  32 , liquid crystal layer  38  is blocked by UV sealant so as to avoid contamination of liquid crystal that causes degradation of display quality. 
   Furthermore, the formation of the metal wall  36  on the substrate  31  is to contact another substrate  32  so as to simultaneously conduct the substrate  31  (i.e. TFT substrate) to the substrate  32  (i.e. CF substrate) as well as to support the structure without conductive adhesive or conductive spacer. 
   The Fourth Preferred Embodiment: Referring to the  FIGS. 9A to 9F , TFT formation process is implemented on substrate  41  therein. As semiconductor layer  47  is deposited, manipulate a mask  43  in order to at least cover the semiconductor layer  47 . Also manipulate another larger frame mask  44  to simultaneously superimpose on the substrate  41 . A frame spacing  45  is thus formed between the two masks  43  and  44  (as illustrated in the top view diagram in  FIG. 9A ). Notice that the material to the masks  43  and  44  does not prone to bond to insulator, such as conductive material, or processed material that does not prone to bond to insulator. Also notice that manipulation of masks  43  and  44  is automated. 
   As deposition is continued, deposition is performed within the frame spacing  45  (as illustrated in  FIG. 9B ). An enclosed insulating wall  46  is built after removal of the two masks  43  and  44  in a predetermined period of time. To complete TFT formation process (as illustrated in  FIG. 9C ), liquid crystal is dropped to the insulating wall  46 , and to enable to form a uniform liquid crystal layer  48 . UV sealant  49  is coated along the periphery of the insulating wall  46  (as shown in a top view diagram of  FIG. 9D  and a cross-sectional view diagram of  FIG. 9E ) so as to pre-seal to another substrate  42 . Then UV type sealant is hardened by UV irradiation so as to bond substrates  41  and  42  together. An annealing process is exerted ultimately and thus a liquid crystal display panel is formed thereof (as illustrated in  FIG. 9F ). 
   Since insulating wall  46  is bonded to the substrates  41  and  42 , the liquid crystal layer  48  has no contact to the UV sealant  49 , liquid crystal is free from contamination that degrades the display quality. 
   Furthermore, the insulating layer  46  formed on the substrate  41  manages to support the structure similar to conventional spacer therein. 
   The Fifth Preferred Embodiment: Referring to  FIGS. 10A to 10F , TFT formation process is performing on substrate  51  therein. After a passivation layer  57  is deposited, to manipulate a mask  53  in order to at least cover the passivation layer  57 , and also manipulate another lager frame mask  54  to simultaneously superimpose on the substrate  51 . A frame spacing  55  is thus formed between the two masks  53  and  54  (as illustrated in top view diagram  FIG. 10A ). Notice that material of masks  53  and  54  does not prone to bond to insulator, such as conductive material, or processed material so as to not prone to bond to insulator. Also notice that manipulation of masks  53  and  54  is automated. 
   As deposition is continued, deposition is performed in the frame spacing  55  (as illustrated in  FIG. 10B ). After removal of the two masks  53  and  54  in a predetermined period of time, an enclosed insulating wall  56  is built therein. In order to complete TFT formation process (as illustrated in  FIG. 10C ), liquid crystal is dropped to the insulating wall  56  and to enable to form a uniform liquid crystal layer  58 . UV sealant  59  is coated along periphery of the insulating wall  56  (as illustrated in the top view diagram of  FIG. 10D  and cross-sectional diagram of  FIG. 10E ) so as to pre-seal to another substrate  52 . Then UV sealant is irradiated by UV light so that substrates  51  and  52  are bonded together. An annealing step is ultimately implemented so as to complete a liquid crystal display panel (as illustrated in  FIG. 10F ). 
   Since the insulating wall  56  is bonded to the substrates  51  and  52 , the liquid crystal layer  58  has no contact to the UV sealant  59  so as to avoid contamination that degrades display quality. 
   Furthermore, the insulating wall  56  formed on the substrate  51  manages to support the structure similar to a conventional spacer. 
   The Sixth Preferred Embodiment: Referring to the  FIGS. 11A to 11F , TFT formation process is performed on a substrate  61 . After a conductive layer  67  (gate metal layer, drain/source metal layer or pixel electrode layer, wherein gate metal layer is introduced as an example) is deposited, manipulate a mask  63  that patterned with a specific circuit design is superimposed on the substrate  51 . Notice that material of mask  63  does not prone to bond to metal, such as insulator, or processed material that does not prone to bond to metal. Also notice that manipulation of the mask  63  is automated (as illustrated in  FIG. 11B ). 
   As deposition is continued, after removal of the mask  63  in a predetermined period of time, a pattern of conductive wall  64  is formed therein. In order to complete TFT formation process (as illustrated in  FIG. 1C ), UV sealant  66  is coated along periphery of substrate  61 , and liquid crystal is dropped to the conductive wall  64  and to enable to form an uniform liquid crystal layer  65 . (as illustrated in top view diagram of  FIG. 11D  and cross-sectional view diagram of  FIG. 11E ). To pre-seal another substrate  62 , then UV sealant is exposed to UV light so as to be hardened as well as bonding substrates  61  and  62  together. Ultimately an annealing process is performed to complete a liquid crystal display panel (as illustrated in  FIG. 11F ). 
   Notice that conductive material (e.g. conductive adhesive or conductive spacer) is not required, for the conductive wall pattern  64  that is formed on substrate  61  manages to conduct from substrate  61  (i.e. TFT substrate) to another substrate  62  (i.e. CF substrate) as well as manages to support the structure. 
   The Seventh Preferred Embodiment: Referring to  FIGS. 12A to 12H , process of TFT formation process is performed on a substrate  71 . After insulating layer  711  (semiconductor layer or passivation layer, semiconductor layer is exemplary herein) is deposited, manipulate a mask  73  so as to at least cover the insulating layer  711 , as well as manipulate a larger frame mask  74  to simultaneously superimpose on the substrate  71 . Thus a frame spacing  75  between the two masks  73  and  74  is implemented therein (as illustrated in top view diagram in  FIG. 12A ). The masks  73  and  74  are not prone to bond with insulating materials, for example, a conductive material, or a processed material that does not bond with insulating materials. Notice thattemptemp the manipulation of masks  73  and  74  is automated. 
   As deposition is continued, as well as depositing in the frame spacing  75  (as illustrated in  FIG. 12B ), an enclosed insulating wall  76  is formed after removal of the two masks  73  and  74  in a predetermined period of time. As a conductive layer (a source/drain metal layer or pixel electrode layer, for example) is deposited thereafter, manipulate a specific patterned mask  77  (as illustrated in top view diagram  FIG. 12C ) while deposition is proceeding (as illustrated in  FIG. 12D ), a specific conducting wall pattern  761  is formed on the substrate  71  after removal of the mask  77  in a predetermined of time. To complete process of TFT formation (as illustrated in  FIG. 12E ), liquid crystal is dropped to the insulating wall  76  and to enable to form a uniform liquid crystal layer  78 . An UV sealant  79  is coated along periphery of the insulating wall  76  (as illustrated in top view diagram in  FIG. 12F  and cross-sectional view diagram in  FIG. 12G ). To pre-seal another substrate  72 , then UV sealant  79  is exposed to UV light so as to be hardened as well as bonding substrate  71  and  72  together. Lastly an annealing process is performed to complete a liquid crystal display panel (as illustrated in  FIG. 12H ). 
   Since that the insulating wall  75  is bonded to the substrates  71  and  72 , the liquid crystal layer  78  has no contact to UV sealant  79  so as to avoid contamination of liquid crystal and degradation of display quality. 
   Also that conductive material (e.g. conductive adhesive or conductive spacer) is not necessary, for the conductive wall pattern that is formed on substrate  71  manages to conduct from substrate  71  (i.e. TFT substrate) to another substrate  72  (i.e. CF substrate) as well as manages to support the structure. 
   The Eight Preferred Embodiment: Referring to  FIGS. 13A to 13H , process of TFT formation process is performed on a substrate  81 . After conductive layer  811  (gate metal layer or source/drain metal layer or pixel electrode layer, where gate metal layer is exemplary herein) is deposited, manipulate a mask  83  so as to at least cover the conductive layer  811 . Also manipulate a larger frame mask  84  to simultaneously superimpose on the substrate  81 , thus a frame spacing  85  between the two masks  83  and  84  is formed therein (as illustrated in top view diagram in  FIG. 13A ). The masks  83  and  84  are not prone to bond with conductive materials, for example, an insulating material, or a processed material that does not to bond with conductive materials. Notice that the manipulation of masks  83  and  84  is automated. 
   As deposition is continued, as well as depositing within the frame spacing  85  (as illustrated in  FIG. 13B ), an enclosed insulating wall  86  is built after removal of the two masks  83  and  84  in a predetermined period of time. As an insulating layer (a semiconductor layer or a passivation layer, for example) is deposited thereafter, to manipulate a specific patterned mask  87  (as illustrated in top view diagram  FIG. 13C ) while deposition is proceeding (as illustrated in  FIG. 13D ), a specific conducting wall pattern  861  is formed on the substrate  81  after removal of the mask  87  in a predetermined of time. To complete process of TFT formation (as illustrated in  FIG. 13E ), liquid crystal is dropped and to enable to form a uniform liquid crystal layer  88 . An UV sealant  89  is coated along periphery of the conductive wall  85  (as illustrated in top view diagram in  FIG. 13F  and cross-sectional view diagram in  FIG. 13G ). To pre-seal another substrate  82 , then UV sealant  89  is exposed to UV light so as to be hardened as well as bonding substrate  81  and  82  together. Lastly an annealing process is executed to complete a liquid crystal display panel (as illustrated in  FIG. 13H ). 
   For the conductive wall  86  are bonded to the substrates  81  and  82 , the liquid crystal layer  88  has no contact to the UV sealant  89  so as to avoid liquid crystal from contamination as well as degradation of display quality. 
   In addition, UV sealant  89  being exposed to UV light for hardening as well as for bonding the substrates  81  and  82 , UV light is entirely blocked from any side of the substrates  81  and  82  for the enclosed conductive wall  86 . (Gate metal layer or source/drain metal layer, for example, yet providing pixel electrode layer being ITO, merely conducting effect takes place instead of masking effect for it is light transmissive.) Thus degradation of liquid crystal is avoided as desired. 
   Also notice that conductive material (e.g. conductive adhesive or conductive spacer) is not required, for the conductive wall pattern formed on substrate  81  manages to conduct voltage from substrate  81  (i.e. TFT substrate) to another substrate  82  (i.e. CF substrate) as well as manages to support the structure. 
   The Ninth Preferred Embodiment: According to the foregoing embodiments and referring to the  FIGS. 14A to 14C , UV sealant  93  optionally coats one substrate  92  such that the UV sealant  93  is located outside of the formed conductive/insulating wall  94  (as illustrated in  FIG. 14A ) as being bonded to another substrate  91 . That is, corresponding to TFT substrate  91 . Liquid crystal is then dropped to the conductive/insulating wall  94  and to enable to form a uniform liquid crystal wall  95  (as illustrated in  FIG. 14B ). To pre-seal the two substrates  91  and  92 , the substrate  92  and the substrate  91  are exposed to UV light so as to harden the UV sealant  93  as well as bonding the two substrates together. A last annealing process is performed and a liquid crystal display panel is thus completed thereby (as illustrated in  FIG. 14C ). 
   The shape and design of a mask (such as a photomask) described in this invention undoubtedly serves to be exemplary and is not necessarily limited to those in foregoing preferred embodiments. Manipulation of masks is automated by any automation equipment. The patterns on a mask serve to this design upon circuitry requirement, whereas the sealant (photo-sealant, e.g. UV sealant, IR sealant, or LASER sealant) also manages to bond to or to form space along with conductive/insulating wall. The formation of the conductive/insulating wall cooperates with any of the deposition steps that form TFT or pixel electrode, i.e. to form at least a single layer/wall (i.e. repeated formation of two or more layers/walls of conductive/insulating structure is possibly introduced). The forming steps, orders and materials arent limited to present invention, for example, to form a conductive/insulating layer on a conductive/insulating layer should be take as one step of forming a conductive/insulating layer, the conductive layer isnt limited to metal, the TFT forming process is not limited to specific masks process and so on. 
   The advantages of the present invention. 
   (1) To form the enclosed wall while to form either layer of TFT on the substrate so as to save additional cost of sealant forming process and material. 
   (2) Enabling to support and conduct without using additional conductive material such as conductive adhesive, conductive spacer and so on. 
   (3) To prevent the liquid crystal from deterioration caused by irradiation of UV light. 
   (4) To prevent the liquid crystal from contamination caused by contact with UV sealant. 
   (5) The liquid crystal can be formed on either one of the two substrates.
