In other words, the bridging electrode 114 is connected across the second sensing electrode 111 in a bridging manner, and is electrically connected to the two first sensing electrodes 110 on opposite sides of the second sensing electrode 111 through the through hole 113.
於本實施方式之此配置下，做為發射電極的第一感應電極110可透過橋接電極114電性連接，其中由於橋接電極114跨越做為接收電極的第二感應電極111，故第一感應電極110與第二感應電極111仍為電性絕緣，如第1A圖所示。於第2A圖之實施方式中，第一感應電極110a與110b之間具有單一的第二感應電極111。詳言之，從第1A圖之側視圖來看，用來電性連接第一感應電極110a及110b之橋接電極114則跨越了單一個的第二感應電極111。但本發明之觸控面板不以此為限，於其他變形例中，兩相鄰之第一感應電極110之間，可設有複數個第二感應電極111，因此橋接電極114則會與複數個第二感應電極111在垂直方向投影方向具有重疊面積。換句話說，用來電性連接兩相鄰之第一感應電極110之橋接電極114可跨越複數個第二感應電極111。 In this configuration of the embodiment, the first sensing electrode 110 as a transmitting electrode can be electrically connected through the bridge electrode 114. The first sensing electrode is connected to the second sensing electrode 111 as a receiving electrode. 110 and the second sensing electrode 111 are still electrically insulated, as shown in FIG. 1A. In the embodiment of FIG. 2A, there is a single second sensing electrode 111 between the first sensing electrodes 110a and 110b. In detail, from the side view of FIG. 1A, the bridge electrode 114 for electrically connecting the first sensing electrodes 110a and 110b spans the single second sensing electrode 111. However, the touch panel of the present invention is not limited thereto. In other variants, a plurality of second sensing electrodes 111 may be disposed between the two adjacent first sensing electrodes 110, so that the bridge electrodes 114 and the plurality The second sensing electrodes 111 have overlapping areas in the vertical direction of projection. In other words, the bridge electrode 114 for electrically connecting the two adjacent first sensing electrodes 110 may span the plurality of second sensing electrodes 111.
於形成橋接電極114的製程中，可先設置第二導體層(未繪示)於絕緣層112上及通孔113內，接著，圖案化第二導體層以形成橋接電極114，使其橋接電極114跨越第二感應電極111，並透過通孔113電性連接第一感應電極110。 In the process of forming the bridge electrode 114, a second conductor layer (not shown) may be disposed on the insulating layer 112 and in the via hole 113. Then, the second conductor layer is patterned to form the bridge electrode 114 to bridge the electrode. The first sensing electrode 110 is electrically connected to the second sensing electrode 111 and is electrically connected to the first sensing electrode 110 .
除此之外，觸控面板100A可更包含色阻層108，其中色阻層108包含色阻109a、109b與109c。色阻109a、109b與109c分別設置於由遮光層104所定義出的畫素區內，且其分 別可為不同顏色之色阻，例如，色阻109a可為紅色(R)、色阻109b可為綠色(G)，而色阻109c可為藍色(B)。 In addition, the touch panel 100A may further include a color resist layer 108, wherein the color resist layer 108 includes color resists 109a, 109b, and 109c. The color resists 109a, 109b, and 109c are respectively disposed in the pixel region defined by the light shielding layer 104, and are divided into Other color resists may be used. For example, the color resist 109a may be red (R), the color resist 109b may be green (G), and the color resist 109c may be blue (B).
請再看到第1A圖、第2C圖與第2D圖。第2C圖繪示第1A圖的觸控面板100A的部分結構的示意圖，其中第2C圖的視角為自第1A圖的第二基板126朝向第一基板102，且顯示介質層122未繪示於第2C圖。亦即，第2C圖僅繪示絕緣層112、橋接電極114、電極層116，其中絕緣層112未被電極層116覆蓋的部分仍以斜線網底繪示之。第2D圖繪示第2C圖的區域D的放大圖，此外，為了方便說明，第2A圖的遮光層104與畫素區(對應之色阻層108)之邊界也以虛線的方式繪示於第2D圖中。 Please see Figure 1A, Figure 2C and Figure 2D again. FIG. 2C is a schematic diagram showing a partial structure of the touch panel 100A of FIG. 1A , wherein the viewing angle of FIG. 2C is from the second substrate 126 of FIG. 1A toward the first substrate 102, and the display medium layer 122 is not shown in FIG. Figure 2C. That is, FIG. 2C only shows the insulating layer 112, the bridge electrode 114, and the electrode layer 116. The portion of the insulating layer 112 that is not covered by the electrode layer 116 is still shown by a diagonal mesh. 2D is an enlarged view of a region D of FIG. 2C. Further, for convenience of explanation, the boundary between the light shielding layer 104 and the pixel region (corresponding color resist layer 108) of FIG. 2A is also shown by a dotted line. In the 2D picture.
於本實施方式中，電極層116包含共用電極區118與保護電極區120，其中共用電極區118設置於絕緣層112上，而保護電極區120設置於絕緣層112上並覆蓋橋接電極114。此外，於部分實施方式中，共用電極區118的數量可以為1個，而保護電極區120的數量可以與橋接電極114的數量相同，其中「共用電極區118的數量可以為1個」之意思為，於電極層116之中，保護電極區120以外的共用電極區118皆透過實體連接而組合於一體。於本實施方式中，電極層116的共用電極區118與保護電極區120可以是透過同一個導體層(未繪示)，經由一道光罩製程形成。舉例而言，可先於絕緣層112與橋接電極114上設置第三導體層(未繪示)，而此第三導體層係做為電極層116。接著，透過圖案化電極層116，將電極層116形成共用電極區118與保護電極區120，其中共用電極區118與保護電極區 120彼此電性絕緣，換言之，共用電極區118與保護電極區120之間具有間隙、彼此分離。此外，由於電極層116的共用電極區118與保護電極區120是透過圖案化同一層導體層所形成，故電極層116之保護電極區120於絕緣層112的垂直投影會落於電極層116之共用電極區118於絕緣層112的垂直投影之外。 In the present embodiment, the electrode layer 116 includes a common electrode region 118 and a protective electrode region 120. The common electrode region 118 is disposed on the insulating layer 112, and the protective electrode region 120 is disposed on the insulating layer 112 and covers the bridge electrode 114. In addition, in some embodiments, the number of the common electrode regions 118 may be one, and the number of the guard electrode regions 120 may be the same as the number of the bridge electrodes 114, wherein “the number of the common electrode regions 118 may be one” means In the electrode layer 116, the common electrode regions 118 other than the guard electrode regions 120 are integrally combined through a physical connection. In the present embodiment, the common electrode region 118 and the protective electrode region 120 of the electrode layer 116 may be formed through a mask process through the same conductor layer (not shown). For example, a third conductor layer (not shown) may be disposed on the insulating layer 112 and the bridge electrode 114, and the third conductor layer is used as the electrode layer 116. Next, through the patterned electrode layer 116, the electrode layer 116 is formed into a common electrode region 118 and a protective electrode region 120, wherein the common electrode region 118 and the protective electrode region The 120 is electrically insulated from each other, in other words, the common electrode region 118 and the guard electrode region 120 have a gap therebetween and are separated from each other. In addition, since the common electrode region 118 and the protective electrode region 120 of the electrode layer 116 are formed by patterning the same layer of conductor layers, the vertical projection of the guard electrode region 120 of the electrode layer 116 on the insulating layer 112 may fall on the electrode layer 116. The common electrode region 118 is outside the vertical projection of the insulating layer 112.
具體而言，如第1A圖所示，電極層116之保護電極區120透過直接接觸橋接電極114，而將橋接電極114包覆，使得橋接電極114被夾於絕緣層112與電極層116之保護電極區120之間。於本實施方式中，保護電極區120係完全包覆橋接電極114，使得橋接電極114沒有曝露於保護電極區120外，亦即橋接電極114無法與顯示介質124接觸。電極層116的材料可為金屬氧化物，且其可為透明的金屬氧化物，例如銦鎵鋅氧化物(Indium-Gallium-Zinc Oxide；IGZO)、銦錫氧化物(Indium-Tin Oxide；ITO)、銦鋅氧化物(Indium-Zinc Oxide；IZO)或其組合。此外，第一感應電極110與第二感應電極111的材料可以是金屬材料與透明導電材料(如金屬氧化物)的其中至少一者，而橋接電極114於本實施方式中的材料也可選擇性地使用金屬材料與透明導電材料(如金屬氧化物)的其中至少一者。 Specifically, as shown in FIG. 1A, the protective electrode region 120 of the electrode layer 116 is covered by the bridging electrode 114 by directly contacting the bridging electrode 114, so that the bridging electrode 114 is sandwiched between the insulating layer 112 and the electrode layer 116. Between the electrode regions 120. In the present embodiment, the guard electrode region 120 completely covers the bridge electrode 114 such that the bridge electrode 114 is not exposed outside the guard electrode region 120, that is, the bridge electrode 114 cannot be in contact with the display medium 124. The material of the electrode layer 116 may be a metal oxide, and it may be a transparent metal oxide such as Indium-Gallium-Zinc Oxide (IGZO) or Indium-Tin Oxide (ITO). Indium-Zinc Oxide (IZO) or a combination thereof. In addition, the material of the first sensing electrode 110 and the second sensing electrode 111 may be at least one of a metal material and a transparent conductive material (such as a metal oxide), and the material of the bridge electrode 114 in the embodiment may also be selected. At least one of a metal material and a transparent conductive material such as a metal oxide is used.
顯示介質層122設置於電極層116與第二基板126之間，其中顯示介質層122包含顯示介質124，其中顯示介質124可為電泳微粒、電泳墨水、親疏水性介質等等。 The display medium layer 122 is disposed between the electrode layer 116 and the second substrate 126, wherein the display medium layer 122 includes the display medium 124, wherein the display medium 124 can be an electrophoretic particle, an electrophoretic ink, a hydrophilic/hydrophobic medium, or the like.
於本實施方式中，透明金屬氧化物製成的電極層116有較佳的安定性，故電極層116之保護電極區120可做為橋 接電極114的保護層，使得橋接電極114不會與顯示介質層122的顯示介質124直接接觸，藉以防止顯示介質124與橋接電極114產生不預期的交互作用。例如，當橋接電極114是由金屬材料製成的時候，透過電極層116之保護電極區120的保護作用，可防止橋接電極114發生氧化或是鏽蝕。另一方面，由於使用電極層116之保護電極區120做為橋接電極114的保護層，故可不用額外形成一層保護層於橋接電極114上，藉以簡化觸控面板100A的製程並降低成本。例如，於電極層116之共用電極區118與保護電極區120形成後，可接著填充顯示介質材料於第一基板102與第二基板126之間，以形成顯示介質層122。 In the present embodiment, the electrode layer 116 made of a transparent metal oxide has better stability, so the protective electrode region 120 of the electrode layer 116 can serve as a bridge. The protective layer of the electrode 114 is such that the bridge electrode 114 does not directly contact the display medium 124 of the display medium layer 122, thereby preventing the display medium 124 from unintended interaction with the bridge electrode 114. For example, when the bridge electrode 114 is made of a metal material, the protection of the guard electrode region 120 of the electrode layer 116 prevents the bridge electrode 114 from being oxidized or rusted. On the other hand, since the protective electrode region 120 of the electrode layer 116 is used as the protective layer of the bridge electrode 114, it is not necessary to additionally form a protective layer on the bridge electrode 114, thereby simplifying the manufacturing process of the touch panel 100A and reducing the cost. For example, after the common electrode region 118 of the electrode layer 116 is formed with the guard electrode region 120, the display medium material may be filled between the first substrate 102 and the second substrate 126 to form the display dielectric layer 122.
進一步而言，電極層116的共用電極區118可使用作為共用電極，而電極層116的保護電極區120可使用作為保護橋接電極114，使得電極層116可透過彼此分離(或彼此電性絕緣)的共用電極區118與保護電極區120同時提供兩種功用，進而簡化了過往觸控面板需設置有一層用以保護橋接電極之絕緣層以及一層作為共用電極之電極層的結構。 Further, the common electrode region 118 of the electrode layer 116 can be used as a common electrode, and the guard electrode region 120 of the electrode layer 116 can be used as the protective bridge electrode 114 such that the electrode layer 116 can be separated from each other (or electrically insulated from each other). The common electrode region 118 and the protective electrode region 120 simultaneously provide two functions, thereby simplifying the structure in which the conventional touch panel is provided with an insulating layer for protecting the bridge electrodes and an electrode layer as a common electrode.
除此之外，於橋接電極114及電極層116之保護電極區120的配置關係中，橋接電極114為位於遮光層104與電極層116之保護電極區120之間，其中橋接電極114於第一基板102的垂直投影落於遮光層104於第一基板102的垂直投影內，且電極層116之保護電極區120於第一基板102的垂直投影落於遮光層104於第一基板102的垂直投影內，換言之，橋接電極114、保護電極區120與遮光層104在垂直投影方向上具有 重疊面積。由於此觸控區域設有多層導電層，當施加電壓之後，則會形成電場而影響顯示介質124的排列方向，進而影響觸控面板的顯示品質。詳言之，位於電極層116之保護電極區120與第二基板126之間的顯示介質124受到此觸控區域的影響而產生非正確的顯示畫面，則可藉由遮光層104來遮蔽，進而提升觸控面板100A的顯示品質。此外，於第2D圖所繪的放大圖之中，保護電極區120的面積小於遮光層104的面積。進一步而言，保護電極區120的寬度W(即與橋接電極114之延伸方向垂直的長度)可小於遮光層104的寬度W’(即與橋接電極114之延伸方向垂直的長度)，使得遮光層104可遮蔽保護電極區120所對應的顯示介質124。 In addition, in the arrangement relationship of the bridging electrode 114 and the protective electrode region 120 of the electrode layer 116, the bridging electrode 114 is located between the shielding layer 104 and the protective electrode region 120 of the electrode layer 116, wherein the bridging electrode 114 is first The vertical projection of the substrate 102 falls within the vertical projection of the light shielding layer 104 in the first substrate 102, and the vertical projection of the protective electrode region 120 of the electrode layer 116 on the first substrate 102 falls on the vertical projection of the light shielding layer 104 on the first substrate 102. Inside, in other words, the bridge electrode 114, the guard electrode region 120 and the light shielding layer 104 have a vertical projection direction Overlap area. Since the touch region is provided with a plurality of conductive layers, when a voltage is applied, an electric field is formed to affect the alignment direction of the display medium 124, thereby affecting the display quality of the touch panel. In detail, the display medium 124 located between the protective electrode region 120 of the electrode layer 116 and the second substrate 126 is affected by the touch region to generate an incorrect display image, which can be shielded by the light shielding layer 104. The display quality of the touch panel 100A is improved. Further, in the enlarged view depicted in FIG. 2D, the area of the guard electrode region 120 is smaller than the area of the light shielding layer 104. Further, the width W of the guard electrode region 120 (ie, the length perpendicular to the extending direction of the bridge electrode 114) may be smaller than the width W' of the light shielding layer 104 (ie, the length perpendicular to the extending direction of the bridge electrode 114), so that the light shielding layer The display medium 124 corresponding to the protective electrode region 120 can be shielded.
綜合上述，於觸控面板的結構中，可透過電極層之保護電極區作為橋接電極的保護層，以防止顯示介質層的顯示介質與橋接電極產生不預期的交互作用，進而延長橋接電極的使用壽命。再者，由於使用電極層之保護電極區做為橋接電極的保護層，故於後續製程中，可不用額外形成一層保護層於橋接電極上，藉以簡化觸控面板的製程並降低成本。此外，由於橋接電極與電極層之保護電極區位於遮光層的一側，故若位於電極層之保護電極區與第二基板之間的顯示介質產生漏光，此漏光將可由遮光層遮蔽，以避免影響觸控面板的顯示品質。 In summary, in the structure of the touch panel, the protective electrode region of the electrode layer can be used as a protective layer of the bridge electrode to prevent the display medium of the display medium layer from unintended interaction with the bridge electrode, thereby prolonging the use of the bridge electrode. life. Furthermore, since the protective electrode region of the electrode layer is used as the protective layer of the bridge electrode, in the subsequent process, an additional protective layer can be formed on the bridge electrode, thereby simplifying the process of the touch panel and reducing the cost. In addition, since the protective electrode region of the bridge electrode and the electrode layer is located on one side of the light shielding layer, if the display medium located between the protective electrode region of the electrode layer and the second substrate generates light leakage, the light leakage may be shielded by the light shielding layer to avoid Affect the display quality of the touch panel.
請再看到第3圖、第4A圖與第4B圖。第3圖繪示本發明第二實施方式之觸控面板100B的側視示意圖，其中第3圖的視角與第1A圖相同。第4A圖繪示第3圖的觸控面板100B 的部分結構的示意圖，其中第4A圖的視角為自第3圖的第二基板126朝向第一基板102，且僅繪示絕緣層112、橋接電極114與導電層128。於第4A圖中，絕緣層112以斜線網底繪示。第4B圖繪示第3圖的觸控面板100B的部分結構的示意圖，其中第4B圖的視角為自第3圖的第二基板126朝向第一基板102，且顯示介質層122未繪示於第4B圖。亦即，第4B圖僅繪示絕緣層112、橋接電極114、電極層116與導電層128，其中絕緣層112未被電極層116覆蓋的部分仍以斜線網底繪示之。 Please see Figure 3, Figure 4A and Figure 4B again. FIG. 3 is a side view of the touch panel 100B according to the second embodiment of the present invention, wherein the viewing angle of FIG. 3 is the same as that of FIG. 1A. 4A is a diagram of the touch panel 100B of FIG. 3 A schematic view of a partial structure in which the viewing angle of FIG. 4A is from the second substrate 126 of FIG. 3 toward the first substrate 102, and only the insulating layer 112, the bridge electrode 114, and the conductive layer 128 are illustrated. In FIG. 4A, the insulating layer 112 is depicted by a diagonal mesh. FIG. 4B is a schematic diagram showing a partial structure of the touch panel 100B of FIG. 3 , wherein the viewing angle of FIG. 4B is from the second substrate 126 of FIG. 3 toward the first substrate 102 , and the display medium layer 122 is not shown in FIG. Figure 4B. That is, FIG. 4B only shows the insulating layer 112, the bridge electrode 114, the electrode layer 116 and the conductive layer 128, wherein the portion of the insulating layer 112 not covered by the electrode layer 116 is still depicted by a diagonal net.
本實施方式與第一實施方式的至少一個差異點為：觸控面板100B更包含導電層128，其中導電層128設置於絕緣層112與電極層116之共用電極區118之間，並與電極層116之共用電極區118電性連接，且橋接電極114與導電層128彼此電性絕緣。進一步而言，導電層128可由電極層116之共用電極區118覆蓋，使得導電層128被夾於絕緣層112與電極層116之共用電極區118之間。於本實施方式中，導電層128於本體104的垂直投影會落於遮光層104的垂直投影內，使得導電層128沿自第一基板102朝第二基板126的方向可具有不可視性。此外，橋接電極114仍跨越第二感應電極111，並透過通孔113電性連接第一感應電極110。 At least one difference between this embodiment and the first embodiment is that the touch panel 100B further includes a conductive layer 128, wherein the conductive layer 128 is disposed between the insulating layer 112 and the common electrode region 118 of the electrode layer 116, and the electrode layer The common electrode region 118 of 116 is electrically connected, and the bridge electrode 114 and the conductive layer 128 are electrically insulated from each other. Further, the conductive layer 128 may be covered by the common electrode region 118 of the electrode layer 116 such that the conductive layer 128 is sandwiched between the insulating layer 112 and the common electrode region 118 of the electrode layer 116. In the present embodiment, the vertical projection of the conductive layer 128 on the body 104 may fall within the vertical projection of the light shielding layer 104 such that the conductive layer 128 may have invisibility in a direction from the first substrate 102 toward the second substrate 126. In addition, the bridge electrode 114 still crosses the second sensing electrode 111 and is electrically connected to the first sensing electrode 110 through the through hole 113.
於本實施方式中，在進行圖案化第二導體層(未繪示)為橋接電極114之步驟時，可將此第二導體層同時圖案化為橋接電極114與導電層128，其中所形成的橋接電極114與導電層128彼此電性絕緣。也就是說，橋接電極114與導電層128是由同一個導體層，經同一道光罩製程進行圖案化後而形成。但 本發明不以此為限，舉例而言，橋接電極114與導電層128亦可不同之導體材料所形成。 In this embodiment, when the step of patterning the second conductor layer (not shown) as the bridge electrode 114, the second conductor layer can be simultaneously patterned into the bridge electrode 114 and the conductive layer 128, wherein the formed The bridge electrode 114 and the conductive layer 128 are electrically insulated from each other. That is to say, the bridge electrode 114 and the conductive layer 128 are formed by the same conductor layer and patterned by the same mask process. but The invention is not limited thereto. For example, the bridge electrode 114 and the conductive layer 128 may be formed of different conductor materials.
對於所形成的橋接電極114而言，橋接電極114於第一基板102的垂直投影面積與遮光層104於第一基板102的垂直投影面積之比值可介於0.001至0.1之間。而對於所形成的導電層128而言，導電層128的面積大於橋接電極114的面積，且導電層128於第一基板102的垂直投影面積與遮光層104於第一基板102的垂直投影面積之比值可為大於0且小於等於0.9。本發明所屬技術領域中具有通常知識者可依實際需由而調整此比值，例如，可視感應電極的圖案而設定此比值。 For the formed bridge electrode 114, the ratio of the vertical projected area of the bridge electrode 114 to the first substrate 102 and the vertical projected area of the light shielding layer 104 on the first substrate 102 may be between 0.001 and 0.1. For the formed conductive layer 128, the area of the conductive layer 128 is larger than the area of the bridge electrode 114, and the vertical projected area of the conductive layer 128 on the first substrate 102 and the vertical projected area of the light shielding layer 104 on the first substrate 102 are The ratio can be greater than zero and less than or equal to 0.9. Those skilled in the art to which the present invention pertains can adjust the ratio according to actual needs, for example, by setting the ratio of the pattern of the sensing electrodes.
於本實施方式中，導電層128可具有浮動電位。於此配置下，電極層116之共用電極區118與導電層128可視為並聯，藉以降低其等效電阻並提升電極層116之共用電極區118的電性傳導能力。由於橋接電極114與導電層128是由同一個導體層經同一道光罩製程而形成，故透過導電層128提升電極層116之共用電極區118的電性傳導能力不需再額外增加光罩製程，亦即，其不會對製造成本造成額外負擔。另一方面，本發明所屬技術領域中具有通常知識者可依所選用的共用電極區118的電阻，而選擇適當的導電層128材料，舉例而言，可使用電阻值小於共用電極區118的金屬材料作為導電層128的材料。 In the present embodiment, the conductive layer 128 may have a floating potential. In this configuration, the common electrode region 118 of the electrode layer 116 and the conductive layer 128 can be considered as parallel, thereby reducing their equivalent resistance and enhancing the electrical conductivity of the common electrode region 118 of the electrode layer 116. Since the bridge electrode 114 and the conductive layer 128 are formed by the same conductor layer through the same mask process, the electrical conductivity of the common electrode region 118 of the electrode layer 116 is increased by the conductive layer 128 without additional mask process. That is, it does not impose an additional burden on manufacturing costs. On the other hand, those skilled in the art to which the present invention pertains can select the appropriate conductive layer 128 material depending on the resistance of the common electrode region 118 selected. For example, a metal having a smaller resistance value than the common electrode region 118 can be used. The material acts as a material for the conductive layer 128.
綜上所述，本發明之觸控面板所包含的電極層包含共用電極區與保護電極區，其中電極層的保護電極區可做為橋接電極的保護層，以防止橋接電極與顯示介質層的顯示介質 產生不預期的交互作用，進而延長橋接電極的使用壽命。由於使用電極層之保護電極區做為橋接電極的保護層，故於後續製程中，可不用額外形成一層保護層於橋接電極上，藉以簡化觸控面板的製程並降低成本。此外，於形成橋接電極的步驟中，也可同步透過同一個導體層形成橋接電極與導電層，其中導電層可與電極層之共用電極區為並聯，藉提升電極層之共用電極區的電性傳導能力。由於橋接電極與導電層是由同一個導體層經同一道光罩製程而形成，故不需再額外增加光罩製程。 In summary, the electrode layer included in the touch panel of the present invention comprises a common electrode region and a protective electrode region, wherein the protective electrode region of the electrode layer can serve as a protective layer of the bridge electrode to prevent the bridge electrode and the display medium layer from being Display medium Unexpected interactions occur, extending the life of the bridge electrode. Since the protective electrode region of the electrode layer is used as the protective layer of the bridge electrode, in the subsequent process, an additional protective layer can be formed on the bridge electrode, thereby simplifying the process of the touch panel and reducing the cost. In addition, in the step of forming the bridge electrode, the bridge electrode and the conductive layer may be simultaneously formed through the same conductor layer, wherein the conductive layer may be connected in parallel with the common electrode region of the electrode layer, and the electrical property of the common electrode region of the lift electrode layer is used. Conductivity. Since the bridge electrode and the conductive layer are formed by the same conductor layer through the same mask process, no additional mask process is required.
