件223等,所以其構造非常複 雜。因而有時會因像素電極2〇 丄與诒唬線22 1之短路、TFT223 之閘電極與汲極電極之短路或 ^ ,原極電極與汲極電極之短路 等而發生亮點像素缺陷的情形 一。 〜冗點像素缺陷,係在液晶 顯示器之驅動或非驅動時與正當 ^ 丁,、止吊像素相較其壳度會變高的 缺陷。党點像素缺陷,會使液晶一 日日纟、貝不态之顯不品質顯著降 低。 因而彳必要將该種的免點像素當作滅點像素,而不使 «之缺陷太顯眼。例如圖4(b)所示,在平面切換型液晶顯 『器210之製造中有因異物231混入,使像素電極麗與信 號線22 1短路而產生免點像素缺陷。該情況像素2 11全體會 爻成儿點像素缺陷。但是若例如利用雷射來切斷像素電極 2〇lb,則焭點像素缺陷就可被消除。又,在對像素電極汕^ ,力、电壓的(f況,無法顯示區域會變成像素211之右上方的 區域,即為由共通電極2131)與213〇所包夾的區域(例如,請 參照專利文獻1)。 ,圖6所示之平面切換型液晶顯示器11 〇,係具有與上述型 式之平面切換型液晶顯示器21〇稍微不同的構造。當將像素 111开y成山形時,液晶分子之配向方向就會變成二方向,且 顯示器之視角會變得更寬廣。 平面切換型液晶顯示器丨1〇,係包含有在絕緣基板上互相 平行所形成的複數條閘極線119 ;介以閘極線丨19及絕緣層 而與問極線11 9相對所形成的複數條第五共通電極丨丨4、 114’,以及連接於第五共通電極114、114,間的第六共通電 90331.doc 1241428 極113a、113e ;且形成於以相鄰的二條第五共通電極m lit、及相鄰之二條第六共通電極113^u3e為邊界之區域 上的像素111,係排列成矩陣狀所構成。 像素ill係包含以下之構成所形成。在第六共通電極U3a ” 113c之間,於圖6中第六共通電極i 13b係連接在下側之第 五共通電極114上,而第六共通電極U3b,係連接在上側之第 五共通電極114,上,並與兩側之第六共通電極U3a、u3c 平行形成。第五共通電極114、114,間,形成有與第五共通 電極114、114’平行的CS電極115。又,第六共通電極n 3a 與113c係在像素111之中央由第六共通電極丨134所連接。 更且,在第六共通電極1134與(:^電極115重疊的位置上, 以介電層與CS電極115相對而配置有銲墊電極117,且將cs 兒極115當作相對電極而形成電容器。在銲墊電極丨丨7上像 素電極101a' 101b、l〇lc、101d係與第六共通電極U3a、 113c平行延伸而連接。介以絕緣層與第六共通電極113&、 113c相對而與之平行形成有信號線121,修復線1〇3係與像 素電極ιοί相對而平行連接在銲墊電極117上。又,TFT123, 係將閘極線119當作閘電極,源極電極或沒極電極係與信號 線121相連接,而汲極電極或源極電極係與修復線ι〇3相連 接。在第六共通電極113與像素電極1 〇 1上,層疊有液晶層。 上述平面切換型液晶顯示器1 1 〇之像素丨i 1,亦與平面初. 換型液晶顯示器210之像素211同樣,單位像素可依第六共 通電極113而大致分割成4個區域。以下為了方便起見,將 由第六共通電極丨13&與第六共通電極U3b,所包夹的區域當 90331.doc -10- 1241428 作區域A,將由第六共通電極U3b,與第六共通電極所 包夾的區域當作區域B,將由第六共通電極113 &與第六共通 電極113b所包夾的區域當作區域c。又,將由第六共通電極 U3b與像素電極1〇ld所包夾的區域定義為仏,將由像素電 極101d與第六共通電極ii3c所包夹的區域定義為。 在平面切換型液晶顯示器110中,將對應上述液晶顯示器 21〇兩端之第六共通電極213的第六共通電極113&、u3c, 介以絕緣層與信號線121重疊配置。另一方面如圖4所示, 在平面切換型液晶顯示器21 〇中,於信號線22 1與像素電極 2〇1之間形成有從CS電極215開始分歧而朝像素21丨之長度 方向延伸的第六共通電極213。因而平面切換型液晶顯示器 110之構造,與平面切換型液晶顯示器210相較可採用高的 開口率。又,由於修復線103係與像素電極101d重疊而連接 在銲墊電極117上,所以修復線103不會降低像素Η丨之開口 率 又’像素電極101及弟六共通電極113,多有為了不使 開口率降低而以ITO (Indium Tin Oxide :銦錫氧化物)等的透 明素材形成的情況。 上述之像素111,由於亦與像素211同樣地在同一基板上 採用複雜的構造,所以在製造時容易發生亮點像素缺陷。 例如在發生開關元件123之閘電極與汲極電極之短路的情 況,像素111全體會變成亮點像素。該情況,如圖2(a)所示-, 在點ρι、P2、P3中藉由雷射切斷像素電極101a、101b、l〇lc 即可使區域A、B、C滅點化。又,在P4藉由雷射切斷第六 共通電極113b,區域Di亦可進行滅點化。 90331.doc -11 - 1241428 但是,如上面所述,由於修復線103係與像素電極l〇u 重璺而連接在銲墊電極1 1 7上,所以當在點P4雷射切斷像素 電極10 Id時,會同時破壞修復線1〇3。當破壞由八丨(鋁)等金 屬所形成的修復線103時,因破壞時飛散而會引起其他的像 素111之配向不良或電極間之短路等。因此在點P5不能以雷 射切斷第六共通電極113c,而區域〇2會以亮點而殘留著。 因而先前技術中,由於與源極_電容器間配線相重疊的梳齒 電極無法切斷,所以無法進行完全的滅點化處理。 另一方面,當不將修復線丨03與像素電極丨〇丨d重疊而連接 在銲墊電極117上時,就可不用破損修復線1〇3而切斷像素 電極101d以使區域A進行滅點化。但是該情況有修復線ι〇3 與像素電極ioid未重疊的面積部分會使像素ηι之開口率 降低的情形。 (專利文獻1) 曰本專利特開平11-125840號公報(第五〜6頁、圖υ 【發明内容】 (發明所欲解決之問題) 因此本發明之目的在於提供一種平面切換型液晶顯示器 抑〇儿點之滅點化方法’其不用減少平面切換型液晶顯示 之開口率即可使在顯不器上產生的亮點像素缺陷滅點 化。 (解決問題之手段) 本發明之平面切換型液晶顯示器,係具有:絕緣基板; 象素在上述絕緣基板上由第一共通電極所包圍住而形 90331.doc -12- 1241428 ^述像素包含有·· cs電極,其與上述第—共通電極連 二墊電極,與上述以電極相對;像素電極,從上述銲 極開始延伸;第二共通電極,其從上述第-共通電極 \上迷像素電極而延伸;修復線,具有連接部與開口部, ^亥連接部㈣接上述銲㈣極;_元件,與上述修 ==料接;WaW4於上述第二共通電極 -♦之上,且上述修復線,係使其開口部與上述 2極相對並與該像素電極平行所形成,而上述連接部則 /、該像素電極相對而與上述鋒墊電極連接。 本發明之平面切換型液晶顯示器’其包含有互相平行形 成。巴緣基板上的複數條閘極線、介以上述問極線及絕緣 層:與該閘極線相對所形成的複數條第三共通電極、及連 接複數條上述第三共通電極且互相平行所形成的第四共通 電極’·排列複數個像素,形成於以相鄰之二條上述第三共 通電極、及相鄰之二條上述第四共通電極為邊界的區域 上,上述像素包含有:cs電極,其於上述閘極相鱼該閑 極線平行所形成;輝塾電極,其與⑽電極相對,而形成 y在成為上述像素邊界之二條第四共通電極間之中央的 第四共通電極與上述cs電極所交又的位置上;像素電極, 其連接於上述銲塾電極所形成,且配置於成為上述像素邊 界之第四共通電極與中央之第四共通電極間,並與該第西 共通電極平行而延伸;信號線,與成為上述像素邊界之第 四共通電極相對而與該第四共通電極平行所形成;修復 線,其包含連接部及開口部,並以該連接部來連接上述鋒 9033 l.doc -13- 1241428 墊電極;開關元件,其以上试彳 、 这$極線為閑電極,源極電極 與上述信號線連接,汲搞雷H Φ u /及極電極與上述修復線之開口部連 接’·以及液晶,注入於上诚楚 江第四/、通電極與像素電極之間; 且上述修復線,係、使上述開σ部與上述像素電極相對並盘 該像素電極平行㈣成,上料接部未與該像素電極相對 而與上述知塾電極連接。 線 上 本毛月之平面切換型液晶顯示器,較佳者係將上述修復 連接4配置於上述液晶之向錯(diselinati⑽)產生位置 \本發明之平面切換型液晶顯示器,其成為上述像素邊界 之第四共通電極亦可為山形。 4本發明之亮點之滅點化方法,係藉由切斷未與上述修復 線相對之像素電極的部分而使在平面切換型液晶顯示器上 所產生的亮點滅點化者。 以下在纟說明書之發明的實施形態中,+面切換型液晶 顯不g ’雖係作為在對像素電極施加電壓的狀態下像素變 成黑,而在施加的狀態下像素變成明亮的正常黑方式之液 2顯示器,而開關元件為了方便起見作為TFT,但是並非限 定本發明之平面切換型液晶顯示器。 【實施方式】 一本發明之實施形態的平面切換型液晶顯示器係如圖斤 不,包含有互相平行形成於絕緣基板上的複數條閘極線 | 乂閘極線1 9與絕緣層與之相對而形成的第一共通電 極14 14 ,以及連接第一共通電極14、14,間的第二共通電 90331.doc -14- 1241428 極13a、13c ;且在由第一共通電極14、14,與第二共通電極 13a、13c所包圍住的區域上形成有像素丨丨❶第二共通電極 13a、13c,例如可為如習知例中所說明的山形。又,第二 共通電極13a、Be亦可在像素U之大略中央的山頂部分利 用第二共通電極13d來連接。 在像素u内,於第-共通電極14、14,間之例如像素_ 大略中央形成有與之平#的以電極15。纟第二共通電極 13a、⑴間從第-共通電極14、14,開始分別延伸設有與第 二共通電極13a、13c平行而位於中央的第二共通電極⑽、 13b’。又,在CS電極15之上方與。電極^相對而形成有銲 塾電極17, CS電極15與鋒塾電極17係形成電容器。更從鲜 ㈣極17開始分別與第二共通電極⑴、Ue平行而延伸設 有像素電極la、lb、1c、Id。像素電極1&、lb、卜、“及 第二共通電極13a、13b、13b,、13d,係例如IT〇等所形成 的透明電極。 、, 在像素U内,與第一共通電極13a、13c相對並與之 平行形成有信號線21。由例如l字型之連接部5與直線之開 口部7所構成的修復線3係利用連接部5而連接在銲墊電極 U上:更將閘極線19當作閘電極,其源極電極或汲極電極 係/、彳。唬線2 1相連接,形成有汲極電極或源極電極與修復 線3之開σ部7連接的TFT23’在第二共通電極與像素電極1 形成有液晶層。信號線21及修復線3,係例如A!(鋁 電金屬所形成。 在本發明之平面切換型液晶顯示器甲,修復線^之開口部 90331.doc 1241428 7:系與㈣電極1d相對而與之平行配置,由於連接部5係成 :例如L子型’所以在未與|素電極id相對的位置上與鲜塾 ,極17相連接。因而如圖2(b)所示,在p5之位置不用破壞修 復線3即可切斷像素電極1。 亦即’如上所述在發生像素電極J與信號線21之短路、開 關元件23之閘電極與沒極電極之短路或源極電極與汲極電 極之短路等的情況’像素11全體就會變成亮點像素。在本 實施形態之情況係如圖2⑻所示,藉由將像素電極I 1c在點Pl、P2、P3中例如制雷射來切斷即可使區域A.

Description of the invention: [Technical field to which the invention belongs] The present invention relates to a flat switching liquid crystal display having a structure capable of extinguishing bright pixels and a method for extinguishing the bright points. [Prior art] There are various liquid crystal display methods for liquid crystal displays used in television or computer monitors. Among them, TN (twistednematlc: twisted nematic) method, (guest-host. Master-slave) method, ECB (electricaUy__tr〇) ❿ ^ b / efringence: electronically controlled birefringence) method is well known. These liquid crystal display methods all adopt an opposing electrode structure in which an applied electric field is perpendicular to the two substrate surfaces sandwiching the liquid crystal layer. On the other hand, in the plane switching type (IPS) method that obtains a wide viewing angle, the applied electric field is parallel to the substrate surface, which is also called the lateral electric field method. / That is, the sharpness of the electric field along the substrate of Li Shaw changes the arrangement of liquid crystal molecules in the substrate surface, and the change in the unique molecular arrangement will produce an epoch-making wide viewing angle that cannot be seen in TN mode . Since the positive and negative electrodes of the planar switching type are comb-shaped in a single substrate, the planar switching type is also referred to as a comb-electrode type in the past. Although there are various creations of the structure of the flat switching liquid crystal display, Japanese Patent Application Laid-Open No. 1 1-125840 (Patent Document 丨) discloses a flat switching liquid crystal display 2 having a structure as shown in FIG. 4 丨〇. In FIG. 4, a pixel 211 of the flat switching liquid crystal display 210 corresponds to an area surrounded by adjacent gate lines 219 and 219 and adjacent signal lines 221 and 221. Rectangular 90331.doc 1241428 221 has sides that are longer than the gate-shaped pixels 2 11, and the sides are formed by lines formed by lines k 221, 219, and 219. From the point of view of the gate electrode 2 1 Q ka & M, the non-polar electrode of the TFT223 (Thin Film D-r :, thin film transistor) with a gate electrode, the pixel electrode 2 is formed by extending in the length direction of the pixel 2m. 〇1, 2〇1. A pad electrode 217 is formed near the center with respect to the longitudinal direction. As a capacitor connected to the pixel electrode 201 and as one of the electrodes, the capacitor extends in a direction perpendicular to the longitudinal direction. The “electrode” is formed on the CS (Capacitance Strage) electrode 215 with a dielectric layer and a pad electrode 217 facing each other. In addition, between the pixel electrodes 201 and 201 and between the signal line 221 and the pixel electrode 201 'are branched from the CS electrode 215 and extend in the length direction of the unit pixel to form the eight-way private electrode 2 1 3, 2 13, 21 3. As shown in FIG. 4, the pixel 211 can be roughly divided into four regions according to the common electrode 213. Fig. 5 is a sectional view taken along the line A-A in Fig. 4. Generally, in a flat switching liquid crystal display of 210, a liquid crystal layer 225 is formed on the pixel electrode 201 and the common electrode 213. An electric field 229 is generated between the pixel electrode 201 and the common electrode 213 by applying a voltage to the pixel electrode 201. The electric field 229 is used to control a pretilt angle parallel to the array substrate of the liquid molecules 227 in the liquid crystal layer 225, and display is performed. In the following, for convenience, the flat switching liquid crystal display 210 in this specification is used as a state in which the pixels 2 and 11 are darkened when no voltage is applied to the pixel electrode 201, and the pixels 22 are in a state where voltage is applied. 1 Normally black LCD that turns into bright spots. The pixel 2 11 of the above-mentioned flat switching liquid crystal display 21 0 is formed with a pixel electrode 201, a common electrode 2 1 3, a gate line 2 1 9, a letter 90331.doc 1241428, a CS electrode 215, Switching element? 223 and so on, so its structure is very complicated. Therefore, bright pixel defects sometimes occur due to a short circuit between the pixel electrode 202 and the bluff line 22 1, a short circuit between the gate electrode of the TFT223 and the drain electrode, or a short circuit between the source electrode and the drain electrode. . ~ Redundant pixel defects are defects in which the degree of crustiness of a pixel is higher than that of a legitimate pixel when the LCD is driven or not. Defective pixel defects can significantly reduce the quality of LCDs and the quality of LCDs. Therefore, it is not necessary to use this type of non-dot pixel as a vanishing pixel without making the defects of «too conspicuous. For example, as shown in FIG. 4 (b), in the manufacture of the flat switching liquid crystal display device 210, foreign matter 231 is mixed in, which causes the pixel electrode to be short-circuited with the signal line 22 1 to generate dot-free pixel defects. In this case, all the pixels 2 to 11 will have a pixel defect. However, if the pixel electrode is cut by 20 lbs using a laser, for example, a small pixel defect can be eliminated. In addition, for the pixel electrode, the force and voltage (f condition, the undisplayable area will become the upper right area of the pixel 211, that is, the area surrounded by the common electrode 2131) and 213 (for example, refer to Patent Document 1). The flat switching liquid crystal display 11 shown in Fig. 6 has a structure slightly different from the flat switching liquid crystal display 21o of the above type. When the pixel 111 is turned into a mountain shape, the alignment direction of the liquid crystal molecules will become two directions, and the viewing angle of the display will become wider. Flat switching liquid crystal display 丨 10, comprising a plurality of gate lines 119 formed parallel to each other on an insulating substrate; a plurality of gate lines 119 and an insulating layer opposite to the interrogation lines 11 9 Fifth common electrodes 4, 4, 114 ', and sixth common currents connected between the fifth common electrodes 114, 114, 90331.doc 1241428 poles 113a, 113e; and formed on two adjacent fifth common electrodes The pixels 111 on the area where m lit and two adjacent sixth common electrodes 113 ^ u3e are boundaries are arranged in a matrix. The pixel ill is formed by the following structure. Between the sixth common electrode U3a and 113c, in FIG. 6, the sixth common electrode i13b is connected to the fifth common electrode 114 on the lower side, and the sixth common electrode U3b is connected to the fifth common electrode 114 on the upper side. , And is formed in parallel with the sixth common electrode U3a, u3c on both sides. Between the fifth common electrode 114, 114, a CS electrode 115 parallel to the fifth common electrode 114, 114 'is formed. Furthermore, the sixth common electrode The electrodes n 3a and 113c are connected in the center of the pixel 111 by a sixth common electrode 134. Further, at a position where the sixth common electrode 1134 and the (: ^ electrode 115 overlap), a dielectric layer is opposed to the CS electrode 115 The pad electrode 117 is arranged, and the cs electrode 115 is used as a counter electrode to form a capacitor. The pixel electrodes 101a '101b, 10c, 101d are on the pad electrode 7 and the sixth common electrode U3a, 113c. Signal lines 121 are formed parallel to the sixth common electrode 113 &, 113c via an insulating layer, and the repair line 103 is opposite to the pixel electrode and is connected in parallel to the pad electrode 117. The TFT123 uses the gate line 119 as a gate. The electrode, the source electrode or the non-electrode system is connected to the signal line 121, and the drain electrode or the source electrode system is connected to the repair line ι03. On the sixth common electrode 113 and the pixel electrode 101, the layers are stacked There is a liquid crystal layer. The pixel of the above-mentioned flat switching liquid crystal display 1 1 〇 i 1 is also the same as the pixel 211 of the flat switching liquid crystal display 210. The unit pixel can be roughly divided into four areas according to the sixth common electrode 113. For the sake of convenience, the sixth common electrode 丨 13 & and the sixth common electrode U3b will be used as the area A between 9031.doc -10- 1241428, and the sixth common electrode U3b will be used in common with the sixth. The area enclosed by the electrodes is referred to as area B, and the area enclosed by the sixth common electrode 113 & and the sixth common electrode 113b is referred to as area c. Furthermore, the area between the sixth common electrode U3b and the pixel electrode 101d is used. The area enclosed is defined as 仏, and the area enclosed by the pixel electrode 101d and the sixth common electrode ii3c is defined as. In the flat switching liquid crystal display 110, a sixth common electrode 213 corresponding to both ends of the liquid crystal display 21o is described. The sixth common electrode 113 &, u3c is arranged to overlap the signal line 121 via an insulating layer. On the other hand, as shown in FIG. 4, in the flat switching liquid crystal display 21 〇, the signal line 221 and the pixel electrode 2 〇 A sixth common electrode 213 extending from the CS electrode 215 and extending in the length direction of the pixel 21 丨 is formed between 1. Therefore, the structure of the flat switching liquid crystal display 110 can be higher than that of the flat switching liquid crystal display 210. Opening rate. In addition, since the repair line 103 is overlapped with the pixel electrode 101d and is connected to the pad electrode 117, the repair line 103 does not reduce the aperture ratio of the pixel, and the pixel electrode 101 and the common electrode 113 are often used to prevent When the aperture ratio is lowered and formed with a transparent material such as ITO (Indium Tin Oxide). The above-mentioned pixel 111 has a complicated structure on the same substrate as the pixel 211, so that bright-spot pixel defects are liable to occur during manufacturing. For example, when a short circuit occurs between the gate electrode and the drain electrode of the switching element 123, the entire pixel 111 becomes a bright pixel. In this case, as shown in FIG. 2 (a)-, the areas A, B, and C can be extinguished by cutting the pixel electrodes 101a, 101b, and 10lc by laser at the points p1, P2, and P3. In addition, in P4, the sixth common electrode 113b is cut by a laser, and the region Di may be extinguished. 90331.doc -11-1241428 However, as described above, since the repair line 103 is connected to the pad electrode 1 1 7 with the pixel electrode 10u, the pixel electrode 10 is cut off by the laser at point P4. When Id, the repair line 103 will be destroyed at the same time. When the repair line 103 formed of metal such as aluminum (aluminum) is destroyed, it may cause misalignment of other pixels 111 or a short circuit between electrodes due to scattering during the destruction. Therefore, the sixth common electrode 113c cannot be cut by a laser at the point P5, and the area 02 remains with a bright spot. Therefore, in the prior art, since the comb-tooth electrode that overlaps the wiring between the source and the capacitor cannot be cut, it is impossible to perform a complete burn-in treatment. On the other hand, when the repair line 丨 03 is not overlapped with the pixel electrode 丨 0d and connected to the pad electrode 117, the pixel electrode 101d can be cut without damaging the repair line 103 to make the area A extinguish. Point. However, in this case, the area where the repair line ι03 and the pixel electrode ioid do not overlap may reduce the aperture ratio of the pixel ι.

The method for extinguishing bright spots of the present invention is to extinguish the bright spots generated on a flat switching liquid crystal display by cutting a portion of a pixel electrode that is not opposed to the repair line. In the following embodiment of the invention described in the specification, the + plane switching liquid crystal display "g" is a normal black mode in which the pixel becomes black under a state where a voltage is applied to the pixel electrode, and the pixel becomes bright under the applied state. The liquid 2 display, and the switching element is a TFT for convenience, but it is not limited to the flat switching liquid crystal display of the present invention. [Embodiment] A flat switching liquid crystal display according to an embodiment of the present invention includes a plurality of gate lines formed parallel to each other on an insulating substrate. 乂 The gate line 19 is opposite to the insulating layer. The first common electrode 14 14 is formed, and the second common current is connected between the first common electrodes 14, 14 and 9031.doc -14-1241428 electrodes 13a, 13c; and between the first common electrodes 14, 14 and Pixels are formed on the area surrounded by the second common electrode 13a, 13c. The second common electrode 13a, 13c may be, for example, a mountain shape as described in the conventional example. In addition, the second common electrode 13a and Be may be connected with the second common electrode 13d at the top portion of the center of the pixel U approximately. Within the pixel u, an equal electrode # 15 is formed between the first and common electrodes 14, 14, for example, at the center of the pixel_ roughly. The second common electrode 13a and the second common electrode 13a and 14b are respectively provided with second common electrodes ⑽, 13b 'which are parallel to the second common electrode 13a, 13c and located in the center. It is also above the CS electrode 15. The electrodes are opposed to each other to form a welding electrode 17, and the CS electrode 15 and the front electrode 17 form a capacitor. Further, starting from the fresh electrode 17, the pixel electrodes la, lb, 1c, and Id are provided in parallel with the second common electrode ⑴ and Ue, respectively. The pixel electrode 1 &, lb, Bu, "and the second common electrode 13a, 13b, 13b, and 13d are transparent electrodes formed of, for example, IT0. In the pixel U, they are in common with the first common electrode 13a, 13c. Signal lines 21 are formed opposite and parallel to each other. A repair line 3 composed of, for example, a l-shaped connection portion 5 and a straight opening portion 7 is connected to the pad electrode U by using the connection portion 5: the gate electrode is further Line 19 is used as a gate electrode, and its source electrode or drain electrode system is connected to 彳. Line 21 is connected to form a TFT 23 'connected with drain electrode or source electrode and opening σ portion 7 of repair line 3. The second common electrode and the pixel electrode 1 are formed with a liquid crystal layer. The signal line 21 and the repair line 3 are, for example, formed by A! (Aluminum electrometal.) In the flat switching liquid crystal display of the present invention, the opening 9031 of the repair line ^ .doc 1241428 7: It is opposite to the dysprosium electrode 1d and is arranged in parallel with it. Since the connecting portion 5 is formed as: for example, L-shaped ', it is connected to the fresh dysprosium and pole 17 at a position that is not opposite to the prime electrode id. Therefore, as shown in FIG. 2 (b), the pixel electrode 1 can be cut without destroying the repair line 3 at the position p5. That is, as described above, when a short circuit between the pixel electrode J and the signal line 21, a short circuit between the gate electrode and the electrodeless electrode of the switching element 23, or a short circuit between the source electrode and the drain electrode occurs, the entire pixel 11 becomes Bright spot pixels. In the case of this embodiment, as shown in FIG. 2 (a), the area A. C can be destroyed by cutting the pixel electrode I 1c at points P1, P2, and P3, for example, by laser. This is the same as the above example. However, in the flat switching liquid crystal display of this embodiment, the connection portion 5 of the repair line 3 is connected to the pad electrode 17 without overlapping the pixel electrode 1d near the pad electrode 17, so it can be connected to the pad electrode 17. Only the pixel electrode ld is cut by the laser. FIG. 2 (c) is an enlarged view showing the & vicinity of the laser cut. Therefore, the area 仏 and 仏 can be simultaneously annihilated without breaking the repair line 3. Because The repair line 3 is not damaged, so it is possible to avoid the misalignment of other pixels 11 or the short circuit between the electrodes due to the fragmentation of the repair line 3 generated when the conventional pixel electrode W performs laser cutting. Repair the connection of line 3 as shown When the arrangement shown in 2 (c) does not overlap with the pixel electrode 1 d, the aperture ratio decreases. When the aperture ratio decreases, it becomes difficult to obtain the brightness required for a liquid crystal display. In the switching liquid crystal display, the applied electric field is parallel to the substrate surface, and the alignment of the liquid crystal molecules can be changed within the substrate surface by using the electric field of 0 / 0ff. However, the alignment of the liquid crystal molecules is in line with the electrode 90331.doc -16- The misalignment near the boundary electrode of 1241428 is likely to be a kind of alignment defect. Fig. 3 is an enlarged view of regions 0 and 01 of the pixel electrode 1 in the mountain-shaped flat switching liquid crystal display 10 of Fig. 2 (b). In order to explain the misalignment, the connection portion 5 of the repair line 3 is not shown in FIG. 3, but only the pixel electrode 丨 and the second common electrode 13 and the liquid crystal molecules 27 are shown. When a voltage is applied between the pixel electrode and the second common electrode ^, most of the liquid crystal molecules are rotated in the direction of the left arrow and aligned in the-direction, for example. However, a voltage is applied to the pixel electrode i at the upper right position in FIG. 3 in a direction different from that of other regions, and liquid crystal molecules 27 are generated in directions different from those of other liquid crystal molecules. As described above, in the mountain-shaped flat switching type liquid crystal display 丨 0, a structure is easily formed in a region where the pad electrode 17 and the pixel electrode 丨 are misaligned in the vicinity of the connection portion of the region D1 without generating a spot. Therefore, as described above, when the connection 邛 5 of the repair line 3 is arranged at the position where the misalignment occurs as shown in FIG. 2 (c), although the aperture ratio is reduced in appearance, the decrease in brightness can be avoided. / As described above, the mountain-shaped flat switching type liquid crystal display 10 of the present invention connects the repair line 3 to the pad electrode 17 without facing the pixel electrode ld, and the connecting portion 5 is formed in an L shape and is disposed on To the wrong position. Since the aperture ratio is not reduced on the solid substrate, the pixel electrode ld may be cut by a laser, for example, so that the entire area of the pixel 11 is destroyed. The shape of the pixel 11 of the flat switching liquid crystal display 10 of the present invention is not limited to the shape of the mountain shown in FIG. In a comb electrode structure in which the pixel electrode and the second common electrode are nested, misalignment is easily generated in the liquid crystal near the corner of the electrode. Therefore, the shape of the pixel 11 of the + plane switching type liquid crystal display of the present invention may be other polygonal 90331.doc -17-1241428 shapes such as a quadrangle and a triangle. As for the pixel u of the flat switching liquid crystal display 10 of the present invention, as long as the opening 7 of the repair line 3 is opposite to the pixel electrode ld, the connection portion 5 is connected to the pad electrode 17 without being opposed to the pixel electrode, and the connection portion 5 is arranged The position where the liquid crystal misalignment occurs is not particularly limited by size, shape, material, and the like. In the above-mentioned embodiment, although the connection portion 5 is L-shaped, the shape of the connection portion 5 is not limited as long as the connection portion 5 connects the opening portion 7 and the pad electrode 17 and is disposed at the position where the misalignment occurs. The connecting portion 5 may have any other shapes such as a U-shape, a V-shape, and an arc shape. The switching element that applies a voltage between the electrodes in the flat switching liquid crystal display 10 of the present invention is not limited to the D-FT, and may be replaced by other means. The pixel electrode and the common electrode are not limited to the IT0 transparent electrode, and may be formed of other materials. Moreover, in the method for turning off the bright spot of the present invention, the cutting method is not limited to laser cutting by laser irradiation. / This invention can also be implemented by applying various improvements, amendments, and changes based on the knowledge of those skilled in the art without departing from the spirit of the invention. (Effects of the Invention) The flat switching liquid crystal display of the present invention is usually a wiring between a source electrode or a drain-capacitor electrode (pad electrode 17 in this specification) which is overlapped and wired (repair line 3 in this specification) The comb-shaped electrode I τ 0 (pixel electrode 1 in the present specification) is arranged so as not to overlap a part near the capacitor electrode. Therefore, in the case where the pixel U becomes a bright spot pixel defect, the pixel electrode, which is, for example, an IT0 electrode, can be cut without breaking the repair line 3 of 90331.doc 1241428. Therefore, the dot defects of the bright spots of the pixels can be processed on the entire area of the pixels. Further, the flat switching liquid crystal display of the present invention is configured by arranging the connection portion 5 of the pixel electrode j and the pad electrode 丨 7 of the repair line 3 which does not overlap with each other at the liquid crystal misalignment generating position. Therefore, in the method for destroying a flat switching liquid crystal display of the present invention, the connection portion 5 of the repair line 3 can perform the erasing treatment on the area where the erasing treatment cannot be performed without reducing the aperture ratio of the pixel. It has made considerable contributions to the relief of out-of-specification defects.
