For example, the support structures are, for example, a cylindrical support structure, an elliptical cylindrical support structure, a cross-shaped columnar support structure, an L-shaped columnar support structure, a regular polygonal columnar support structure, and an irregular polygonal columnar support structure. - In a preferred embodiment of the invention, the spacing of the second portions of the support structures is greater than the maximum lateral deformation of the second portions of the support structures. For example, the spacing between the second portions of the support structures is, for example, 1/2 of the width of the third portion of the support structures. The invention provides a liquid crystal display panel, which is mainly composed of a first substrate, a second substrate, a liquid crystal layer and a gap support. The second substrate is disposed above the first substrate, and the liquid crystal layer is disposed between the first substrate and the second substrate. In addition, the gap support is also disposed between the first substrate and the second substrate, and the gap support has a plurality of convex patterns, and the convex patterns are in contact with the first substrate or the second substrate. In a preferred embodiment of the present invention, the minimum height Φ of the raised patterns is, for example, 1/4 of the height of the gap support, and the height maximum of the raised patterns is, for example, the height of the gap support. /4. In a preferred embodiment of the present invention, the raised patterns are, for example, in the form of a column, for example, a cylindrical shape, an elliptical column shape, a ten-shaped column shape, an L-shaped column shape, and a regular polygon. At least one of a columnar shape and an irregular polygonal column shape. In a preferred embodiment of the invention, the spacing between the raised patterns is greater than the maximum amount of lateral deformation of the raised patterns. For example, the pitch between the patterns of these protrusions 1316622 98-3-4 is, for example, 1/2 of the width of the raised patterns. - In a preferred embodiment of the invention, the above-mentioned first substrate is, for example, an active element array substrate ' and is, for example, a thin film transistor array substrate. Further, the second substrate is, for example, a color filter substrate. In an example, the first portion of the above-mentioned branch structure is disposed on a color filter substrate and has a color; the light-receiving substrate includes, for example, a black matrix, and the gap support is disposed therein.

The above and other objects, features, and advantages of the present invention will become more apparent from the understanding of the appended claims appended claims [Embodiment] FIG. 2 is a cross-sectional view showing a liquid crystal display panel in accordance with a preferred embodiment of the present invention. Referring to Fig. 2, the liquid crystal display panel 2 is mainly composed of a first substrate 210, a second substrate 220, a liquid crystal layer 230, and a gap support 240. The second substrate 22 is disposed above the first substrate 21A. In the present embodiment, the first substrate 210 is, for example, an active device array substrate composed of a transparent substrate 212 1316622 98-3-4 and a plurality of active elements 214 and a halogen electrode 2i6 disposed thereon. Moreover, since the reaction speed of the thin film tmnsistor 'TFT is good, the present embodiment uses, for example, a thin film transistor as the active element 214 for driving the liquid crystal display panel 200. In other words, the first substrate 21A of the present embodiment is preferably a thin film transistor array substrate. In addition, the second substrate 220 is, for example, a color filter substrate, which is mainly composed of a transparent substrate 222 and a black matrix 224, a color filter layer 226, and a common electrode 228 disposed thereon. Composition. Those skilled in the art will appreciate that the technique of fabricating a color filter layer on a thin film transistor array (Color Filter on Army 'COA) has been widely applied to many liquid crystal displays, so the present invention does not enclose the first substrate 21 The second substrate 220 is defined by the above-mentioned type. As shown in FIG. 3, the first substrate 21 can also be disposed on the active device array with the color light-emitting layer, and the second substrate 220 is shared by the transparent substrate 222. The electrode 228 is constructed. Referring to FIG. 2, the liquid crystal layer 230 is disposed between the first substrate 21 and the second substrate 220, and the gap support 240 is disposed between the first substrate 210 and the substrate 220 to maintain the A gap between the substrate 21 〇 and the second substrate 220 (that is, the cell gap of the liquid crystal display panel 2 )). Here, the gap support 240 has a plurality of convex patterns 24〇a, and the pitch 屯 between the convex patterns 240a is, for example, larger than the lateral deformation amount of the convex pattern 240a. For example, the pitch 屯 is, for example, 1/2 larger than the width of the convex pattern 240a. Here, the width of the convex pattern 24〇a is, for example, 1.2 μm. 1316622 98-3-4

另外，由於本實施例之間隙支撐物240是形成在彩色 /慮光片基板上’也就疋所謂的S〇C(spacer on color filter) 技術，所以間隙支撐物240的凸起圖案24〇a例如是接觸於第一基板210。當然，熟習此技藝者也可以將間隙支撐物 24〇形成於主動元件陣列基板上，而使間隙支撐物的凸起圖案240a與第二基板220接觸（未繪示），本發明並未對其加以限定。 X 一圖4繪示為本發明之一較佳實施例中間隙支撐物的侧視示意圖。請參照圖4，值得一提的是，間隙支撐物24〇可以是由多數支撐結構242所組成。其中，這些支撐έ士構 242分別具有第一部位242a與第二部位24邡，且這撐結構242的第-部位242a是連接於彼此，而第二部位2仙則是相距-間距+。由此可知’圖2及圖3之間隙支撐物 240的凸起圖案240a即是由這些支撐結構2犯的第二鳩所構成。換言之，在S0C技術中，這些支標結構⑽ 的第一部位242a是配置於彩色濾光片基板上。特別的是，支撐結構242例如是呈柱狀，且其位242a及/或第二部位242b可以是圓柱狀（如圖/ α 橢圓柱狀（如圖6所示）、梯形柱狀（如圖7所示其他規則多邊雜狀與不_多邊雜狀（树=疋本發明並不限定其雜。另外，_支撐物之Μ 如是感光材料，且其例如是利用曝光及顯影的 ^ 成，而支標結構242之第二部位242b (也就是間隙工= 24〇的凸起圖案24〇a)的高度hi即是取決於間隙支稽物 1316622 98-3-4 的材質、顯影製程中所使用的顯影劑以及顯影時間等。值得注意的是’支撐結構242之第二部位242b高度 4是大於或等於支撐結構242之總高度h的1/4 (例如是〇.3微米）。換言之，凸起圖案240a的高度h!是大於或等於間隙支撐物240的總高度h，以使間隙支撐物24〇具有撓性(flexibility)，而在第一基板210與第二基板220承受外加壓力時，容易因應此外力而產生形變。如此一來，在液晶顯示面板200的組立過程中，相關人員即能夠輕易地擠壓液晶顯示面板200，以使其具有適當的晶穴間距。另方面，凸起圖案240a的高度^是小於等於間隙支撐物總高度h的3/4，以避免液晶顯示面板2〇〇承受較大的壓應力時，間隙支撐物240發生側向傾倒或斷裂。由上述可知，本發明之間隙支撐物可以是由多數部分 ^豐的支#結構賴成’耻本發明可靖由控制這些支疊率來增加間隙支職的下底面積’或是縮小率:以Ϊ肽的上底面積，進而得到較佳的支撐力與製程良早以下將以模擬數據說明之。支撐=支撑物與習知間隙支撐物之過程是以的關係曲線圖。值得—提的是，此模擬平方的梯形間隙支樓物作為對 = 千方發明之間隙支榜物A、B处;、二並::面積不同的本底=為，嶋平方的四個支撐結構，藉由下化四個支撐結構的下底重疊率例如是80 12 1316622 98-3-4 %。換言之，間隙支撐物A是具有盘而其下底面積則例如是〗平同之上底面積，是由上述四個支撐結構所隙支樓物β亦而間隙一下底=如==7。%’ 糾知t同支Γ物縮的率支下广間隙支榜:Β的支撐物a的支標面積:小’而間隙支 =合改變間棟支撐物之上底面積的製程t可二:;吏在錯由增加間隙支撐物的下底面積，來增加复支仍可 =高間隙支撐物的支#力，以使液晶顯;;進構Γ ’由於本發明之崎物可；支按、、口構所縣，且各個支#結構㈣二錢 ^連，因此與具有_上底_的習知目較之下，本购之間隙支#物具錄佳的撐物夠在承受小應力時產生形變，而不會斷裂或傾倒。斤以能除此之外’本發日収可以藉紐制來減少間隙支撐物的上底面積，進而提高=== 間隙支撐物之支樓面積與壓縮率的關係曲線習；隙支揮物A’的上底面積例如是習知間隙 ς二 :的叫而間隙支擔物Β，的上底面積例如是； I物之上底面積的89%。此外，這三個_ 下、面積均相同。又琛物的下底由圖9可知，在相同的壓縮率之下，間隙支·Α， 13 1316622 98-3-4 具有最小的上底面積，其次是間隙支撐物B’，而習知的間隙支撐物則是具有最大的上底面積。因此，在這三種間隙支撐物中，間隙支撐物A’具有最佳之撓性，其次則是間隙支撐物B’。由此可知，本發明之間隙支撐物A’與間隙支撐物B’在承受壓應力時，其下底可提供與習知間隙支撐物相同的支撐力，而其上底則因具有較佳之撓性，因此能夠避免其發生斷裂或侧向傾倒的問題。In addition, since the gap support 240 of the present embodiment is formed on a color/light-damping substrate, that is, a so-called spacer on color filter technique, the convex pattern 24 〇a of the gap support 240 For example, it is in contact with the first substrate 210. Of course, those skilled in the art can also form the gap support 24 on the active device array substrate, and the bump pattern 240a of the gap support is in contact with the second substrate 220 (not shown), and the present invention does not Limited. Figure 4 is a side elevational view of a gap support in accordance with a preferred embodiment of the present invention. Referring to FIG. 4, it is worth mentioning that the gap support 24〇 may be composed of a plurality of support structures 242. The support gentlemen 242 have a first portion 242a and a second portion 24, respectively, and the first portion 242a of the support structure 242 is connected to each other, and the second portion 2 is a distance-pitch +. From this, it can be seen that the convex pattern 240a of the gap support 240 of Figs. 2 and 3 is constituted by the second weir which is made by these support structures 2. In other words, in the SOC technology, the first portion 242a of the support structures (10) is disposed on the color filter substrate. In particular, the support structure 242 is, for example, columnar, and its position 242a and/or the second portion 242b may be cylindrical (as shown in FIG. / α elliptical column (as shown in FIG. 6 ), trapezoidal column ( FIG. Other regular polygonal irregularities and non-multilateral hybrids shown in Fig. 7 (tree = 疋 The present invention is not limited to the impurities. In addition, the _ support is, for example, a photosensitive material, and it is, for example, exposed and developed. The height hi of the second portion 242b of the support structure 242 (that is, the bump pattern 24〇a of the gap = 24 〇) is determined by the material of the gap member 1136622 98-3-4 and used in the development process. Developer and development time, etc. It is worth noting that the height 4 of the second portion 242b of the support structure 242 is greater than or equal to 1/4 of the total height h of the support structure 242 (for example, 〇.3 μm). In other words, convex The height h! of the pattern 240a is greater than or equal to the total height h of the gap support 240 to make the gap support 24〇 flexible, and when the first substrate 210 and the second substrate 220 are subjected to an applied pressure, It is easy to deform in response to the external force. In this way, in the liquid crystal display During the assembly process of the panel 200, the relevant person can easily press the liquid crystal display panel 200 to have an appropriate hole spacing. On the other hand, the height of the convex pattern 240a is equal to or less than the total height h of the gap support. 3/4, to prevent the liquid crystal display panel 2 from being subjected to a large compressive stress, the gap support 240 is laterally dumped or broken. As can be seen from the above, the gap support of the present invention may be a branch of most parts. #结构赖成' shame The invention can control the rate of these substations to increase the area of the bottom area of the gap support' or the reduction rate: the upper base area of the quinone peptide, thereby obtaining better support and good process The following will be explained by the simulation data. Support = the relationship between the support and the conventional gap support is a graph of the relationship. It is worth mentioning that this simulated square trapezoidal clearance branch is used as the pair = the gap between the inventions Supporting the A and B sites; and the second:: The different backgrounds of the area = the four support structures of the square, the lower bottom overlap ratio of the four support structures by the lowering is, for example, 80 12 1316622 98-3 -4 %. In other words, between The gap support A has a disk and the lower bottom area is, for example, the same as the upper bottom area, and the above four supporting structures are used to support the structure β and the gap is lower than the bottom ====7.%' Knowing that the ratio of the same branch is the same as that of the branch: the support area of the support a: the small 'and the gap support = the process of changing the bottom area of the support of the intermediate support can be two:; In the wrong case by increasing the area of the bottom of the gap support, to increase the complex support can still be = the support of the high gap support, so that the liquid crystal is displayed; the structure Γ 'because of the invention of the goods; The mouth of the county, and each branch # structure (four) two money ^ connected, so compared with the knowledge of the _ upper base _, the purchase of the gap branch #物具的好物 enough to withstand small stresses Deformation occurs without breaking or pouring. In addition to the above, the 'this day's daily income can be used to reduce the upper base area of the gap support, and then increase the === relationship between the area of the support and the compression ratio of the gap support; The upper base area of A' is, for example, the conventional gap :2: and the gap support Β, the upper base area is, for example, 89% of the top surface area of the object. In addition, these three _, the same area. The bottom of the object is also shown in Fig. 9. Under the same compression ratio, the gap support, 13 1316622 98-3-4 has the smallest upper base area, followed by the gap support B', and the conventional The gap support has the largest upper base area. Therefore, in these three gap supports, the gap support A' has the optimum flexibility, and secondly the gap support B'. Therefore, it can be seen that when the gap support A' and the gap support B' of the present invention are subjected to compressive stress, the lower bottom can provide the same supporting force as the conventional gap support, and the upper bottom is better to be scratched. Sex, so it can avoid the problem of its fracture or lateral dumping.

更特別的是，由於間隙支撐物A，與間隙支撐物B’的撓性佳，因此在組立液晶顯示面板的過程中，工作人員能夠適當地擠壓面板，使其具有適當的晶穴間距。換言之，本發明能夠提高液晶顯示面板之液晶滴下式注入的製程良率，進而避免造成液晶垂流或產生氣泡的現象。另外值得一提的是’本發明之液晶顯示面板可以依據兩基板上的膜層厚度，而配置不同高度的間隙支撐物，以增加製程良率，並且使液晶顯示面板受到外力壓迫時，仍可維持一定的晶穴間距。More specifically, since the gap support A is excellent in flexibility with the gap support B', the worker can appropriately press the panel to have an appropriate hole pitch during the assembly of the liquid crystal display panel. In other words, the present invention can improve the process yield of the liquid crystal dropping type injection of the liquid crystal display panel, thereby avoiding the phenomenon of causing liquid crystal sag or bubble generation.
