Abstract:
A method for manufacturing a liquid crystal device involves the forming of a plurality of non-linear devices on a surface of a first substrate in an array and an insulating layer is formed overlying the non-linear devices. In order to minimize the formation of fissures in electrodes which are to be formed in contact with the upper surfaces of the respective non-linear devices arranged in a line and insulated from side surfaces of these devices through the insulating layer, the part of the insulating layer that is parallel to the surface of the substrate is removed by etching in a manner leaving only portions of the insulating layer that extend along the side surface of the device normal to the surface of the first substrate. The method also serves to prevent the effective area of a pixel defined by the electrode from being decreased by the insulating layer.

This is a divisional application of Ser. No. 796,897, filed Nov. 12, 1985, abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a liquid crystal display panel which employs liquid crystal display devices each of which has a nonlinear element having a diode characteristic and a liquid crystal element. The invention also pertains to methods for the manufacture of the liquid crystal display panel. 
     2. Description of the Prior Art 
     Heretofore there has been proposed a display panel which employs m×n (where n≧1 and m≧1) liquid crystal display devices M 11  to M 1n , M 21  to M 2n , . . . and M m1  to M mn . The liquid crystal display device M ij  (where i=1, 2 . . . n, j=1, 2 . . . n) has a nonlinear element U ij  having a diode charateristic and a liquid crystal element L ij . 
     In this display panel, the liquid crystal display device M ij  is connected to a row conductive layer F i  and a column conductive layer H j  at their intersection. 
     With such a display panel, an image display can be provided by driving the liquid crystal devices M 11  to M mn  using the row conductive layers F i  to F m  and the column conductive layers H 1  to H n . 
     However, the conventional display panel is very complex in the structure of the nonlinear element U ij , in the structure of the liquid crystal element L ij  and in the structure for connecting the liquid crystal display device M ij  to the row conductive layer F i  and the column conductive layer H j . 
     On this account, the prior art liquid crystal display panel is difficult to manufacture and expensive. 
     Furthermore, it is difficult to arrange m×n liquid crystal display devices M 11  to M mn  in an (m×n) matrix form with a high density, so that resolution of the image display is relatively low. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the present invention to provide a novel liquid crystal display panel which employs liquid crystal display devices each of which has a liquid crystal element and a nonlinear element having a diode characteristic and connected in series with the nonlinear element. 
     Another object of the present invention is to provide novel methods for the manufacture of such liquid crystal display panel. 
     In accordance with an aspect of the present invention, the liquid crystal display panel comprises (a) first and second substrate members disposed opposite at a predetermined distance in substantially parallel relation to each other and (b) liquid crystal filled between the first and second substrate members. 
     The first substrate member comprises (a) a first substrate having an insulating surface, (b) a plurality m of stripe-like conductive layers F 1 , F 2  F 3  . . . F m  arranged in the first substrate in the column direction and extending in the row direction, (c) a plurality n of layers Q i1  to Q in  arranged on the conductive layer F i  (where i=1, 2 . . . m) in the row direction and having substantially the same width as the later, (d) a conductive layer E ij  being formed on the layer Q ij  (where j=1, 2 . . . m) and having the same width and length as the later, (e) a portion D ij  of the conductive layer F i  underlying the layer Q ij , the layer Q ij  and the conductive layer E ij  constituting a laminate member A ij , (f) insulating layers K ij  and K ij  &#39; each formed over the entire areas of side faces of the laminate member A ij  (or (f)&#39; a insulating layers K i  formed on the first substrate and extending between the laminate member A i1  to A in  and A.sub.(i+1)1 to A.sub.(i+1)n) and (g) a conductive layer C ij  formed on the first substrate and corresponding to the laminate member A ij , the conductive layer C ij  having substantially the same width as the length of the laminate member A ij  and extending on the side face of the insulating layer K ij  and onto the insulating layer K ij , the laminate member A ij  and the insulating layer K ij  &#39;, and the both side faces defining the width of the conductive layer C ij  being substantially in agreement with the both side faces defining the length of the laminate member A ij  (or (g)&#39; a conductive layer C ij  formed on the insulating layer K i  and corresponding to the laminate member A ij , the conductive layer C ij  having substantially the same width as the length of the laminate member A ij  and extending onto the laminate member A ij , and the both side faces defining the width of the conductive layer C ij  being substantially in agreement with the both side faces defining the length of the laminate member A ij ). 
     The second substrate member comprises (a) a second substrate having an insulating surface, and (b) a plurality n×q (where q is an integer equal to or greater than 1) of stripe-like conductive layers H 11 , H 12  . . . H 1q  ; H 21 , H 22  . . . H 2q  ; . . . and H n1 , H n2  H n3  . . . H nq  sequentially arranged on the second substrate in the row direction and extending in the column direction, the conductive layers H j1  to H jq  being opposite the conductive layers C 1j  to C mj . 
     The laminate member A ij  forms a nonlinear element U ij . The conductive layer H jr  (where r=1, 2, . . . q), a portion B ijr  of the conductive layer C ij  confronting the conductive layer H jr  and the portion of the liquid crystal filled between the conductive layer H jr  and the portion B ijr  forms a liquid crystal element L ijr . 
     According to such a liquid crystal display panel of the present invention, the liquid crystal element L ijr  can be driven by applying a driving signal to the liquid crystal display element M ijr  via the row conductive layer F i  and the column conductive layer H jr . Accordingly, the liquid crystal display panel provides an image display. 
     Since the liquid crystal element L ijr  is formed by the conductive layer H jr , the portion B ijr  of the conductive layer C ij  facing the conductive layer H jr  and the portion of the liquid crystal between the conductive layer H jr  and the portion B ijr , as mentioned above, the liquid crystal element L ijr  is simple in structure. 
     Furthermore, the nonlinear element U ij  is formed by the aforementioned laminate member A ij , and hence is simple in construction.

     Accordingly, the liquid crystal/display panel of the present invention is far simpler in structure than is conventional, in consequence of which m×(m×q) display crystal elements M 111  to M mnq  can be arranged in an m×(n×q) matrix form with a high density, ensuring to provide an image display with high resolution. 
     Moreover, according to the present invention, the liquid crystal display panel which has the aforesaid excellent feature can be produced by a manufacturing method of the present invention which includes a step of (A) preparing a first substrate member, (B) preparing a second substrate member, (C) turning the second substrate member upside down and disposing the first and second substrate members in opposing and substantially parallel relation to each other and (D) filling liquid crystal in the gap defined by the first and second substrate members.

H nq  sequentially arranged in the row direction and extending in the column direction, the conductive layers H j1 , H j2 , . . . and H iq  corresponding to the conductive layers C 1j , C 2j , . . . and C mj  of the first substrate member. 
     The manufacturing method of the present invention requires only three masks for the fabrication of the liquid crystal display, that is, one for the formation of the laminate member A 1  to A m , one for the formation of the conductive layers C 11  to C mn  and the laminate members A 11  to A mn  and one for the formation of the conductive layers H 11  ˜H 1r  to H n1  ˜H nr .

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIGS. 1 to 5 illustrate an embodiment of the liquid crystal display panel of the present invention, in which a substrate 1 has an insulating surface. The substrate 1 is formed of, for instance, alkaline free glass. 
     The substrate 1 has sequentially arranged thereon in column direction a plurality m of row conductive layers F 1 , F 2  . . . F m . The row conductive layer F i  may preferably be composed of a layer 2 formed of, for example, aluminum and a nontransparent layer 3 formed of, for instance chromium. 
     The row conductive layer F i  has sequentially formed thereon a plurarity of n layers Q i1 , Q i2  . . . Q in  each of which is formed, for example, non-single-crystal semiconductor. The layers Q i1 , Q i2  . . . Q in  have same width as the row conductive layer F i . 
     The layer Q ij  (where i=1, 2 . . . m and j=1, 2 . . . n) may have, for example, an n-i-n type structure composed of an n-type layer, an i-type layer and an n-type layer, an n-i-p (or p - )-i-n type structure composed of an n-type layer, an i-type layer, a p(or p - )-type layer, an i-type layer and an n-type layer, a p-i-p type structure composed of a p-type layer, an i-type layer and a p-type layer, or a p-i-n(or n - )-i-p type structure composed of a p-type layer, an i-type layer, an n(or n - )-type layer, an i-type layer and an p-type layer. The layer Q ij  also may be only a very thin insulating layer which may pass tunnel current. But FIGS. 1 to 5 show the case where the layer Q ij  has the n-i-n type structure. For the sake of brevity, the following description will be made in connection with the case where the layer Q ij  has the n-i-n type structure. 
     The layer Q ij  has an n-type non-single-crystal silicon layer 21 formed on the row conductive layer F i , an i-type layer 22 of non-single-crystal semconductor formed on the layer 21 and an n-type non-single-crystal silicon layer 23 formed on the layer 22. The layer 22 is formed principally of silicon but contains carbon (C), nitrogen (N) or oxygen (O) in an amount of 1/10 or less relative to the silicon, and hence is formed of non-single-crystal semiconductor expressed by Si x  C 1-x  (where 0&lt;×&lt;1). 
     The layer Q ij  is covered over the entire area of its top surface with a conductive layer E ij . The conductive layer E ij  is formed of, for instance, chromium. 
     The part of the conductive layer F i  underlying the layer Q ij , the layer Q ij  and the conductive layer E ij  make up a layer member A ij . 
     The layer member A ij  are covered over the entire area of its opposite side surfaces with insulating layers K ij  and K ij  &#39;, respectively. The insulating layers K ij  and K ij  &#39; are formed of, for instance, silicon nitride or silicon oxide and have 0.1 to 0.5 μm in thickness. 
     The substrate 1 has arranged thereon in a matrix form m×n (where m&gt;1, and n&gt;1) conductive layers C 11  to C 1n , C 21  to C 2n , C 31  to C n , . . . and C m1  to C mn . 
     The conductive layer C ij  (where i=1, 2, . . . m and j=1, 2, . . . n) is rectangular in shape and has a relatively large area, for example, 100 μm wide and 150 μm long. 
     The conductive layer C ij  extends on the layer member A ij  i.e. the conductive layer E ij  and the insulating layer K ij  and K ij  &#39; through the side surface of the insulating layer K ij  and make contact with the conductive layer E ij . The conductive layer C ij  has substantially same width as the length of the layer member A ij  i.e. the conductive layer E ij  and is formed of, for instance, chromium and is nontransparent. In this case, the opposing side surfaces of the conductive layer C ij , which determine the width of the conductive layer C ij  are substantially aligned with the opposing side surfaces of the layer member A ij , which determine the long of the layer member A ij . 
     Furthermore a relatively thin insulation protecting layer 25 is deposited on the substrate 1 to cover the conductive layer C 11  to C mn , the active layers A 11  to A 1n , A 21  to A 2n  . . . A m1  to A mn , the insulating layer K 11  to K mn  and K 11  &#39; Tto K mn  &#39; and parts of the row conductive layers F 1 , F 2  . . . F m  which are not covered with the conductive layers C 11  to C 1n , C 21  to C 2  . . . C m1  to C mn . 
     The conductive layers F 1  to F m , the layer members A 11  to A mn , the insulating layers K 11  to K mn  and K 11  &#39; to K mn  &#39; and the conductive layers C 11  to C mn  make up a substrate member 7. 
     The substrate member 7 is formed, for example, as follows: 
     A conductive layer F which will ultimately form the row conductive layers F 1  to F m , a layer Q which will utlimately form the layers Q 11  to Q mn  and a conductive layer E which will ultimately form the conductive layers E 11  to E mn  are deposited in that order on the substrate 1, as shown in FIGS. 9A to 9E. The conductive layer F, the layer Q and the conductive layer E make up a layer member A which will ultimately form the layer members A 11  to A mn . 
     The conductive layer F may be formed by a known method, for instance, a sputtering or electron beam evaporation process. 
     The layer Q also may be formed by a known method, for example, a CVD, plasma CVD or photo CVD method. 
     In my experiment, the substrate 1 formed hereon the conductive layer F was loaded through a loading and unloading chamber into a first reaction chamber, wherein a glow discharge was produced over the substrate 1 at a high frequency of 13.56 MHz in an atmosphere containing silane SiH 4 , phosphine PH 3  and hydrogen, with the substrate temperature held in the range of 200° to 250° C. As a result of this, an n-type microcyrstalline silicon layer, which had a conductivity of 10 -2  to 10 2  (Ωcm) -1  and contained hydrogen as a recombination center neutralizer, was deposited 300 to 1000 Å thick on the conductive layer F. Next, the substrate 1 was moved from the first reaction chamber into the next second reaction chamber, wherein a gas mixture of silane Si m  H 2m+2  (where m=1, 2, 3, . . . ) (for example, SiH 4 ) and methyl silane SiH n  (CH 3 ) 4-n  (where n=1, 2, 3) was discharged into a plasma, by which an i-type nonsingle-crystal silicon layer of Si x  C 1-x  was deposited 0.2 to 1 μm thick on the n-type layer. After this, the substrate 1 was returned from the second reaction chamber to the first reaction chamber, wherein another n-type layer similar to the above n-type layer was deposited by the same method of the i-type non-single-crystal silicon layer, thus obtaining the laminate member Q having the n-i-n type structure. 
     The conductive layer E may also be formed by a known method, for instance, a sputtering or electron beam evaporation process. 
     Next, the layer member A is subjected to a known pattern process using a first mask, providing m layer members A 1  to A m  of the same pattern as row the conductive layers F 1  to F m , as shown in FIGS. 10A to 10E. 
     Next, a insulating layer K which will ultimately form the insulating layer K 11  to K mn  and K 11  &#39; to K mn  &#39; and which is relatively thin than the layer member A 1  to A m  is deposited by a known method, for example, plasma CVD method on the entire surface of the substrate 1 to cover the active layers A 1  to A m , as shown in FIGS. 11A to 11E. 
     Next, the insulating layer K is selectively etched away by a known method, for example, a plasma etching method to form insulating layers K i  and K i  &#39; on both sides of the laminate member A i  difining the width of the laminate A i , as shown in FIGS. 12A to 12E. 
     Next, a conductive layer C is diposited on the entire area of the substrate 1 to cover the laminate member A 1  to A m  and insulating layers K 1  to K m  and K 1  &#39; to K m  &#39; as shown in FIGS. 13A to 13E. 
     Next, the conductive layer C, the layer Q 1  to Q m  and the conductive layer E 1  to E m  of the layer members A 1  to A m  are patterned by a known method using a second mask into the conductive layers C 11  to C mn , the layers Q 11  to Q mn  and the conductive layers E 11  to E mn  as shown in FIGS. 14A to 14E. In this case, the conductive layer F 1  to F m  are not patterned. The layer Q ij , the part of the conductive layer F i  underlying the layer Q ij  and the conductive layer E ij  make up the laminate member A ij . 
     Next, the insulating layers K 1  to K m  and K 1  &#39; to K m  &#39; are selectively etched away by a known method into the insulating layer K 11  to K mn  and K 11  &#39; K mn  &#39;. 
     Next, the thin insulation protecting layer 25 is deposited on the entire surface of the substrate 1 to cover the conductive layers C 11  to C mn , the layer members A 11  to A mn , the insulating layers K 11  to K mn  and K 11  &#39; to K mn  &#39; and the part of the conductive layer F 1  to F m  which are not covered with the conductive layers C 11  to C nm . 
     Referring now back to FIGS. 1 to 5, another substrate member 11, which is different from the aforementioned substrate member 7 is provided. 
     The substrate member 11 has, on a substrate 12 corresponding to the substrate 1, a plurality of n×q (where q≧1, in this instance q=3) sequentially arranged column conductive layers H 11 , H 12  and H 13  ; H 21 , H 22  and H 23  ; . . . H n1 , H n2  and H n3  which are arranged opposing relation to the conductive layers C 11  to C m1  ; C 12  to C m2  ; . . . C 1n  to C mn , respectively and extend in the column direction. The column conductive layer H j1 , H j2  and H j3  can be obtained by forming a conductive layer through a known method on the substrate 12 and then patterning the conductive layer through a third mask. 
     The column conductive layers H j1 , H j2  and H j3  are covered over entire surfaces thereof with red, green and blue filters S j1 , S j2  and S j3 , respectively. 
     Furthermore, an insulation protecting layer 26 formed of, for instance, organic region is deposited on the entire surface of the substrate 12 by a known method, for example, coating to cover the filters S 11  to S n1 , S 12  to S n2  and S 13  to S n3 . 
     The substrate member 11 is disposed upside down by a suitable support means (not shown) in opposing relation to the top of the substrate member 7 in parallel thereto. In this instance, the conductive layers C 1j  to C mj  of the substrate member 7 and the column conductive layers H j1 , H j2  and H j3  of the substrate member 11 are held face-to-face with each other. 
     A space defined by the substrate members 7 and 11 is filled with liquid crystal 13. 
     In the structure described above in conjunction with FIGS. 1 through 5, a part 14 of the conductive layer C ij  on the substrate 1 and a part 15 of the conductive layer H jr  (where r=1, 2, 3) on the substrate 12, which are face-to-face with each other and a part 16R of the liquid crystal 13 between the part 14 of the conductive layer C ij  and the part 15 of the conductive layer H jr  constitute a liquid crystal element L ijr  which employs the parts 14 and 15 as its electrodes B ijr  and B ijr  &#39;, respectively. 
     When low voltages are applied across the part 14 serving as electrode B ijr  of the conductive layer C ij  and the part 15 serving as electrode B ijr  &#39; of the conductive layer H jr  ; the liquid crystal element L ije  remain opaque, but when high voltages are applied, it become transparent. 
     The layer member A ij  constitute a nonlinear element U ij  which employs the part 17 of the conductive layer F i  underlying the layer Q ij  and the conductive layer E ij  as its electrodes D ij  and D ij  &#39;, respectively. The element U ij  presents such a nonlinear voltage(V)-current(A) characteristic curves 51 and 61 as shown in FIGS. 6 and 7. The element U ij  has an offset voltage which is intermediate between the voltage that makes the liquid crystal element L ijr  transparent and nontransparent, respectively. 
     The liquid crystal element L ijr  and the nonlinear element U ij  are connected in series with each other, and hence make up a liquid crystal display device M ijr . 
     According to the arrangement described above with respect to FIGS. 1 through 5, the electrode B ijr  of the liquid crystal element L ijr  and the electrode D ijr  &#39; of the nonlinear element U ij  are common each other. The electrode B ijr  &#39; of the liquid crystal elements L 1jr  of the liquid crystal display devices M ijr  is connected to the column conductive layer H jr  and the electrode D ij  of the nonlinear element U ij  is connected to the conductive layer F i . Furthermore, the column conductive layer H j1 , H j2  and H j3  are covered with the red, green and blue filters S j1 , S j2  and S j3 , respectively. 
     Therefore, according to the arrangement described above in connection with FIGS. 1 to 5, since the liquid crystal element L ijr  can be controlled to be transparent or nontransparent, respectively, by applying, through use of row and column decoders 51X and 51Y, across the liquid crystal display device M ij1 , M ij2  and M ij3  via the conductive layers F i  and H j1 , F i  and H j2 , and F i  and H j3  red, as shown in FIG. 8, green and blue drive signals a color display can be provided. 
     Accordingly, the liquid crystal display panel shown in FIGS. 1 to 5 can be provided a color image display. 
     FIG. 15 to 19 illustrate another embodiment of the liquid crystal display panel of the present invention. 
     In FIGS. 15 to 19 like parts corresponding to those in FIGS. 1 to 5 are identified by the same reference numerals and no detailed description will be given of them. 
     The liquid crystal display panel shown in FIGS. 15 to 19 has the same construction as depicted in FIGS. 1 to 5 except the following points: 
     The insulating layers K i1  to K in  and K.sub.(i+1)1 &#39; to K.sub.(i+1)n &#39; in FIGS. 1 to 5 are substituted with a insulating layer K i . The insulating layer K i  extends between the laminate members A i1  to A in  and A.sub.(i+1)1 to A.sub.(i+1)n and substantially flush therewith, therefor the conductive layer C ij  is formed on the insulating layer K i  and extends onto the laminate member A ij  and the insulating layer K.sub.(i-1). 
     Further, the column conductive layer H i1 , Hj2 and H j3  in FIGS. 1 to 5 are substituted with a column conductive layer H j , and therefor the liquid crystal display device M ij1 , M ij2  and M ij3  are substituted with a liquid crystal display device M ij . 
     Furthermore, the filters S 11  to S n1 , s 12  to S n2  and S 13  to S n3  are omitted. 
     According to the arrangment described above with respect to FIGS. 1 through 5, the electrode B ijr  of the liquid crystal element L ij  and the electrode D ij  &#39; of the nonlinear element U ij  are common to each other. The electrode V ij  &#39; of the liquid crystal elements L 1j  of the liquid crystal display devices M ij  is connected to the column conductive layer H j  and the electrode D ij  of the nonlinear element U ij  is connected to the conductive layer F i . Therefore, according to the arrangement described above in connection with FIGS. 15 to 19, since the liquid crystal element L ij  can be controlled to be transparent or nontransparent, respectively, by applying, through use of row and column decoders 51X and 51Y, across the liquid crystal display device M ij , M ij  and M ij  via the conductive layers F i  and H j  drive signal a monocolor display can be provided. 
     Accordingly, the liquid crystal display panel shown in FIGS. 1 to 5 can be provided a monocolor image display. 
     The substrate member 7 dipicted in FIGS. 15 to 19 can be manufactured, for example, as follows: 
     A conductive layer F which will ultimately form the conductive layers F 1  to F n , a layer laminate member which will ultimately form the layer laminate members Q 11  to Q mn  and a conductive layer E, which will ultimately form the conductive layers E 11  to E mn  are deposited in that order on the substrate 1, as shown in FIGS. 21A to 21E as in the case with the example shown FIGS. 9A to 9E. The conductive layer F, the non-single-crystal semiconductor layer Q and the conductive layer E make up a active layer member A which will ultimately form the active layer member A 11  to A mn  as described previously. 
     Next, the active layer member A is subjected to a known pattern process using a first mask, providing m layer members A 1  to A m  of the same pattern as the conductive layers F 1  to F m , as shown in FIGS. 22A to 22E, as is the case with the example shown in FIGS. 10A to 10E. 
     Next, a insulating layer K of photo resist which will ultimately form the insulating layer K i  is deposited by a known method, for example, a plasma CVD method on the entire surface of the substrate 1 to cover the layers A 1  to A m , as shown in FIGS. 23A to 23E. 
     Next, the insulating layer K is irradiated by light 30 without using any mask as shown in FIGS. 23A to 23B and then is developed into the insulating layer K i , as shown in FIGS. 25A to 24E. 
     Next, a conductive layer C is deposited on the entire area of the substrate 1 to cover the laminate member A 1  to A m  and the insulating layer K 1  to K m  as shown in FIGS. 25A to 25E. 
     Next, the conductive layer C, the conductive layers E 1  to E m  and the layers Q 1  to Q m  of the layer member A 1  to A m  are patterned by a known method using a second mask into the conductive layers C 11  to C mn , the layers Q 11  to Q mn  and the conductive layers E 11  to E mn  of the layer member A 11  to A mn , as shown in FIGS. 26A to 26E. 
     Next, the thin insulating layer 26 is deposited on the entire surface of the substrate 1 to cover the conductive layers C 11  to C mn , the layer members A 11  to A mn , the insulating layers K 1  to K m  and the parts of the conductive layers F 1  to F m  which are not covered with the conductive layers C 11  to C mn . 
     It will be apparent that the above embodiment should be construed as merely illustrative of the present invention and should not be construed as limiting the invention specifically thereto and that various modifications and variations may be effected without departing from the scope of the novel concepts of the invention.
