^照圖2’晝素陣列結構包括多條掃描線2G2、多條 資以及多個畫素結構21G。掃描線2()2與資料線 相父,並圍出多個晝素區P。晝素結構21〇則配置於 畫素區P中。各個畫素結構210包括主動元件212、畫素 電,2M以及儲存電容。主動元件212與對應的掃描線旦2〇2 及資料線204電性連接,而晝素電極214電性 件212» 期^ —儲存電容下電極216配置於晝素區P周邊,且儲存電 ^下電極216與晝素電極m部分重疊以構成儲存電容。 當畫素結構210進行顯示時’儲存電容有助於維持晝素電 8 99-7-16 極214的顯示電壓。因此,應用晝素陣列結構2〇〇的液晶 顯示器所顯示的影像較為穩定,也就是顯示影像中不會發 生殘影或是閃爍的現象。然而,儲存電容下電極216由不 透光的金屬材質製成,所以儲存電容下電極216的配置可 月b會影響晝素結構210的顯示開口率。為解決上述問題, 本發明在此提出以不同膜層分段製作儲存電容下電極 216’使得儲存電容下電極216與鄰近的線路不易發生短路 現象。如此一來,可縮短儲存電容下電極216與鄰近的線 路間的距離以提南顯示開口率,更進一步提高晝素陣列結 構200的製程良率。 具體來說’儲存電容下電極216包括第一線段216A 與第二線段216B。第一線段216A與第二線段216B由不 同膜層所組成。第一線段216A鄰近資料線204配置,而 第二線段216B鄰近掃描線202配置。另外,第一線段216A 與其鄰近的資料線204為不同的膜層而第二線段216B與 其鄰近的掃描線202為不同的膜層。以本實施例而言,儲 存電容下電極216之外形例如為Πί,且儲存電容下電極 216包括二個第一線段216A,而第二線段216B的兩端分 別與此二個第一線段216A交疊。此外,畫素結構21〇中 更包括有位於第一線段216A與第二線段216B交疊處的接 觸窗218 ’且第一線段216A與第二線段216B藉由接觸窗 218電性連接。 當然’本發明之儲存電容下電極216並不限定於门型 外形。在其他實施例中,儲存電容下電極216例如不與主 9 1329776 99-7-16 動元件212相交或重疊而構成接近C字型圖案,圍繞於畫 素區P周邊大部分區域。舉例而言,儲存電容下電極216 例如配置於畫素區P的四周,且具有一對應主動元件212 的開口部位。 圖3繪示為圖2之畫素結構210的上視示意圖。請參 照圖2與圖3,在畫素結構210中,第二線段216B與掃描 線202由不同膜層製作而成。由上視圖觀之,即使縮短第 二線段216B與掃描線202間的距離d,第二線段216B與 掃描線202間仍不易發生短路的問題。因此,相較於習知 的晝素結構110而言’儲存電容下電極216的第二線段 216B部分可以更靠近掃描線202,因而有助於增加晝素結 構210的顯示開口率。此外,第一線段216A與資料線206 亦為不同膜層,因此也有助於提昇晝素結構21〇的顯示開 口率。 根據實際測試結果發現,與習知畫素結構110比較, 本實施例之晝素結構210有較高的顯示開口率(依晝素設 計而定,一般至少大於1%),所以在相同的光源條件下, 應用晝素結構210之液晶顯示面板也具有較高的光線穿透 度。因此,畫素結構210的設計可以提升背光源的光線使 用率,因而有助於降低背光源的能源耗費。換言之,應用 畫素結構210的液晶顯示器不需搭配高亮度的背光模組或 是昂責的增亮骐就可以達到足夠的顯示亮度,以進一步節 省成本。 圖4A〜圖4D繪示為圖2之晝素陣列結構沿剖線AA, 10 1329776 99-7-16 的製作方法剖面圖。請先同時參照圖2與圖4A,在一基板 400上形成一第一金屬層410。第一金屬層410包括一 ^極

連接資料線204之一源極212B以及一汲極212C。源極 212B與汲極212C位於閘極212A上方之圖案化半導體層 430上。第二線段216B藉由接觸窗218電性連接第一線段 216A以形成儲存電容下電極216,其中儲存電容下電極 216位於晝素區p周邊。 由於’相鄰近的掃描線202與第二線段216B分別為 第一金屬層410與第二金屬層44〇,其中第一金屬層41〇 與第二金屬層440之間至少配置有閘絕緣層42〇。因此, 11 1329776 99-7-16 Γ線近的第二線段216B不容易發生短路的現 象,而使晝素陣列結構200具有較高的製程良率。掃描線 202與鄰近的第二線段216B之間的距離可以較f知晝素 結構11G之設計更為縮短’以增加畫素陣列結構遍^顯 π開口率。此外’資料線2〇4與相鄰近的第'線段216八 也是不同的金屬層,所以也具有上述之優點。

In general, a thin film transistor liquid crystal display mainly consists of two substrates each having a halogen array and a color filter array, and a liquid crystal layer disposed between the substrates. Figure 1 is a partial schematic view of a conventional halogen array structure. The pixel array structure 1 includes a plurality of scan lines 102, a plurality of data lines 104, and a plurality of pixel structures 110 electrically connected to the scan lines 1 and 2 and the data lines 104. The scan line 102 intersects the data line 104 to form a plurality of pixel regions P (only one is shown in FIG. 1), and the pixel structure 110 is disposed in the pixel region P. The halogen structure 11 includes an active element 112 and a pixel electrode 114.

The present invention proposes a pixel array structure comprising a plurality of scanning lines, a plurality of 6 1329776 99-7-16 lines, and a plurality of pixel structures. The scanning line and the data line enclose a plurality of pixel regions, and the scanning lines and the data lines corresponding to the electrical connection of the pixel elements are located in the corresponding pixel regions. Each of the pixel structures includes a main body, a component, a halogen electrode electrically connected to the active component, and a storage capacitor. The storage capacitor lower electrode is disposed around the halogen region and overlaps the halogen electrode portion to form a capacitor. The storage capacitor lower electrode includes at least a first line segment adjacent to the data line and at least a second line segment adjacent to the scan line. The first line segment and the second line segment are different film layers and the first line segment and the adjacent one of the data lines are different film layers and the second line segment and the adjacent one of the scanning lines are different film layers. The present invention further provides a method of fabricating a pixel array structure comprising the following steps. A first metal layer is formed on a substrate, and the first metal layer includes a plurality of gates, a plurality of scan lines and a plurality of first line segments. The gate is connected to the scan line, and the first line segment is separated from the scan line. Then, a gate insulating layer and a semiconductor layer are sequentially formed on the substrate, and the gate insulating layer covers the first metal layer. Then, a portion of the gate insulating layer and a portion of the semiconductor layer are removed to form a patterned semiconductor layer and a plurality of contact windows. The patterned semiconductor layer is located above the gate of the gate and the contact window exposes the end of the first line segment. A second metal layer is then formed on the substrate. The second metal layer includes a plurality of second line segments adjacent to the scan line, a plurality of data lines adjacent to the first line segment, a plurality of sources connected to the data lines, and a plurality of drains. The data line intersects the scan line to form a plurality of pixel regions. The source and drain are above the gate. The second line segment is electrically connected to the first line segment through the contact window to form a plurality of storage capacitor lower electrodes, wherein the storage capacitor lower electrode is located around the pixel region. 7 1-329776 99-7-16, the different line body of the 阙 material capacitor is also the line segment of each lower electrode and the adjacent scanning and data guides of the pixel array structure of the invention and its situation H ^ It is not easy to have a short circuit with a short circuit in the adjacent line. In addition, the column structure and the _^^ method prevent the short pull 66. The present invention is not required to maintain the h 66 ί and the storage capacitor Tf pole and its _ conductor line. The above and other objects, features, and advantages of the present invention will become more apparent from the aspects of the invention. 2 is a schematic diagram of a structure of a halogen array according to an embodiment of the present invention. 2. The pixel array structure includes a plurality of scanning lines 2G2, a plurality of elements, and a plurality of pixel structures 21G. The scanning line 2() 2 and The data line is the father and encloses a plurality of pixel regions P. The halogen structure 21〇 is disposed in the pixel region P. Each pixel structure 210 includes an active element 212, a pixel power, 2M, and a storage capacitor. 212 is electrically connected to the corresponding scanning line 2 2 and the data line 204, and the halogen electrode 214 is electrically connected to the periphery of the pixel region P, and the storage electrode is disposed. 216 is partially overlapped with the halogen electrode m to constitute a storage capacitor. When the pixel structure 210 is performed When displaying, the 'storage capacitor helps to maintain the display voltage of the halogen battery 8 99-7-16 pole 214. Therefore, the image displayed by the liquid crystal display using the halogen array structure is stable, that is, the display image is not There is a phenomenon of image sticking or flickering. However, the storage capacitor lower electrode 216 is made of an opaque metal material, so the arrangement of the storage capacitor lower electrode 216 may affect the display aperture ratio of the halogen structure 210. To solve the above problems, the present invention proposes to fabricate the storage capacitor lower electrode 216' with different film layers so that the storage capacitor lower electrode 216 and the adjacent circuit are less prone to short circuit. Thus, the storage capacitor lower electrode 216 can be shortened and adjacent. The distance between the lines shows the aperture ratio in the south, and further improves the process yield of the pixel array structure 200. Specifically, the storage capacitor lower electrode 216 includes a first line segment 216A and a second line segment 216B. The first line segment The 216A and the second line segment 216B are composed of different film layers. The first line segment 216A is disposed adjacent to the data line 204, and the second line segment 216B is disposed adjacent to the scan line 202. In addition, the first The segment 216A is a different film layer from its adjacent data line 204 and the second line segment 216B is a different film layer from its adjacent scan line 202. In this embodiment, the storage capacitor lower electrode 216 is shaped as, for example, Πί, and stored. The capacitor lower electrode 216 includes two first line segments 216A, and two ends of the second line segment 216B overlap the two first line segments 216A, respectively. Further, the pixel structure 21〇 further includes a first line segment. The contact window 218 ′ at the intersection of the 216A and the second line segment 216B and the first line segment 216A and the second line segment 216B are electrically connected by the contact window 218. Of course, the storage capacitor lower electrode 216 of the present invention is not limited to the gate type. shape. In other embodiments, the storage capacitor lower electrode 216, for example, does not intersect or overlap with the main 9 1329776 99-7-16 moving element 212 to form a near C-shaped pattern that surrounds a substantial portion of the perimeter of the pixel region P. For example, the storage capacitor lower electrode 216 is disposed, for example, around the pixel region P and has an opening portion corresponding to the active device 212. 3 is a top plan view of the pixel structure 210 of FIG. 2. Referring to FIG. 2 and FIG. 3, in the pixel structure 210, the second line segment 216B and the scan line 202 are made of different film layers. From the top view, even if the distance d between the second line segment 216B and the scanning line 202 is shortened, the problem of short circuit between the second line segment 216B and the scanning line 202 is less likely to occur. Therefore, the portion of the second line segment 216B of the storage capacitor lower electrode 216 may be closer to the scanning line 202 than the conventional halogen structure 110, thereby contributing to an increase in the display aperture ratio of the pixel structure 210. In addition, the first line segment 216A and the data line 206 are also different film layers, and thus also contribute to the display opening ratio of the halogen structure 21〇. According to the actual test results, compared with the conventional pixel structure 110, the halogen structure 210 of the embodiment has a higher display aperture ratio (depending on the design of the element, generally at least greater than 1%), so the same light source is used. Under the condition, the liquid crystal display panel using the halogen structure 210 also has high light transmittance. Therefore, the pixel structure 210 is designed to increase the light usage of the backlight, thereby helping to reduce the energy cost of the backlight. In other words, the liquid crystal display using the pixel structure 210 can achieve sufficient display brightness without the need for a high-brightness backlight module or an acclaimed brightening , to further save costs. 4A-4D are cross-sectional views showing the fabrication method of the pixel array structure of FIG. 2 along the line AA, 10 1329776 99-7-16. Referring to FIG. 2 and FIG. 4A simultaneously, a first metal layer 410 is formed on a substrate 400. The first metal layer 410 includes a cathode 212A, a scan line 202, and a first line segment 216, the gate 212A is connected to the scan line 202, and the first line segment 216A is away from the scan line 202. Actually, the first line segment 216A and the scanning line 202 do not contact or overlap each other, and the extending direction of the first line 4 216A intersects with the extending direction of the scanning line 202. Corresponding to each of the pixel regions P, the first line segment 216A is connected to the first line segment 216A of the adjacent pixel region P, for example. Next, please refer to FIG. 2 and FIG. 4B simultaneously, and sequentially form a substrate 400. The gate insulating layer 420 and a patterned semiconductor layer 43 are covered, and the gate insulating layer 420 covers the gate 212A. In addition, the gate insulating layer 420 has a contact window 218 thereon. The patterned semiconductor layer 43 is located above the gate 212A, and the contact window 218 exposes the end of the first line segment 216A. Then, please refer to FIG. 2 and FIG. 4C simultaneously to form a second metal layer 440 on the substrate 400. The second metal layer 44A includes a second line segment 216B adjacent to the scan line 2〇2, a data line 204 adjacent to the first line segment 216A, a source 212B connecting the data line 204, and a drain 212C. Source 212B and drain 212C are located on patterned semiconductor layer 430 over gate 212A. The second line segment 216B is electrically connected to the first line segment 216A via the contact window 218 to form a storage capacitor lower electrode 216, wherein the storage capacitor lower electrode 216 is located around the pixel region p. Since the adjacent scan lines 202 and the second line segments 216B are the first metal layer 410 and the second metal layer 44, respectively, at least the gate insulating layer 42 is disposed between the first metal layer 41 and the second metal layer 440. Hey. Therefore, 11 1329776 99-7-16 The second line segment 216B near the twist line is not prone to short circuit, and the halogen array structure 200 has a high process yield. The distance between the scan line 202 and the adjacent second line segment 216B can be made shorter than that of the design of the pixel structure 11G to increase the aperture ratio of the pixel array structure. In addition, the data line 2〇4 and the adjacent ''line segment 216' are also different metal layers, so they also have the above advantages. Furthermore, please refer to FIG. 2 and FIG. 4D simultaneously, a protective layer 450 is formed on the substrate to cover the second metal layer 44 (), and a plurality of halogen electrodes 2 are formed on the protective layer 45. The electrical connection is not poled 21 and the edge of the pixel electrode 214 and the storage capacitor lower electrode 216 are substantially partially formed to constitute a storage capacitor. Thus, the halogen array structure 200 is formed in the present embodiment, and the contact window 218 and the patterned semiconductor layer 43 are formed, for example, by the half-transparent cover shown in the off-state 5. Referring to FIG. 4D and FIG. 5 simultaneously, the translucent cover has a plurality of transparent regions T of different transmittances. Corresponding to the single halogen region p, the light transmitting region T1 corresponds to the upper side of the contact window 218. The light transmitting region T2 corresponds to the upper portion of the patterned semiconductor layer 43A, and the light transmitting region T3 is located for other regions. In detail, the method of forming the patterned semiconductor layer 430 and the contact window 218 is as shown in Figs. 6A to 6E. First, referring to FIG. 6A, a gate insulating layer 420, a semiconductor layer 432, and a photoresist layer (not shown) are sequentially formed on the substrate 400. At the same time, a photoresist layer (not shown) is patterned using the translucent cover 500 to form a patterned photoresist layer 610. The gate insulating layer 420 and the semiconductor layer 432 cover the 12th 99-7-16 = genus layer 41. In the present embodiment, the semiconductor layer 43 (four) layer 436. Incoming amorphous dream = when a medium-prepared method such as 疋 is doped to dope the dopant into the amorphous material ===== two = two and the layer (10) has at least one opening 612 = first region 6 4 and opening The secret 614 outside the 612 and the first position correspond to the gate 212A of the first line 616 ° opening 612 of the first line segment 216. At the end of w, the first region 614 corresponds to the house, and the patterned photoresist layer 610 has a thickness in the first region 614 that is greater than the thickness in the second region 616. Then, referring to Fig. 6B, the exposed portion σ & ^^ s conductor layer 432 and the half exposed by the intermediate drawer 4fn 612 are, for example, subjected to a side-side process to form a contact window 218. The step of the step and the patterning of the semiconductor diode region 616 of the faint layer ★ the resist layer 61 〇 3 = the body layer 432 and the gate insulating layer (four) to avoid the secret = /, the lower + conduction 弁 reference map, remove the first Part of the second region (4) 荦 = layer: This step is, for example, a picture: a portion of the patterned photoresist layer (10) of the germanium region 616 has = degrees, and a portion of the first region 014 is blocked by A u With thickness. Therefore, when the second region of the photoresist layer 610 has a thicker portion of the patterned photoresist layer 610, the first region 614 is completely removed during the ash 29776 99-7-16 process. There are still some parts that have not been removed, so as to follow the first (4) as the first mask, please refer to FIG. 6D and FIG. 6E, and use the first area 614 i to remove the resist layer 610 as a mask. Part of the semiconductor layer 432. The patterned photoresist layer 51 of the first region 214 is removed from the layer 430. The semiconductor layer 432 3 in the second region 616 is removed, leaving only over the gate 212A = two without the need for a different mask: this helps to save on the cost of the purchase and the mask. Of course, under different process designs, the present invention 2 is divided into different masks to form 218 and patterned semiconductor layer 430, respectively, in different processes. ^ Riding in the painting material hiding method of the present invention and the manufacturing method thereof, each line segment of the lower electrode of the thinking storage valley is different from the adjacent metal line, or the storage capacitor lower electrode and the adjacent metal line, for example, sweep = A short circuit is unlikely to occur between the lines.
