201106068 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種製作顯示面板之方法，尤指一種對配向膜材 料進行紫外光處理或電漿處理，以鈍化可交聯污染物之製作顯示面 板之方法。 【先前技術】 ® 液晶顯示器係利用液晶分子在不同排列狀態下’對光線具有不 同的穿透量來控制顯示晝素的亮度或色彩’進而使液晶顯示器得以 產生豐富的影像。因此，液晶顯示器中通常具有配向膜，用以讓鄰 近配向膜之液晶分子產生特定配向方向，以便調控晝素内之液晶傾 ’J方向。傳統的配向方法主要可區分為配向膜材料塗布或形成以及 配向處理兩個階段，其中配向膜之材質通常以聚亞醯胺 鲁 (polyamide，PI)為主，在聚亞醯胺塗布於基板後，再進行配向處 理。 針對配向膜材料塗布處理階段，若使用傳統的印刷式塗布處理 中’轉印_rintingr〇lier)表面通常會具有一層光阻層，以作為轉印 之用為了維持良好之印刷效果，轉印輕表面之光阻層通常不會達 到完全交聯的程度，但這些未完全交聯之光阻可能會隨著印刷製程， 4 201106068 一併轉印至基板上，導致污染。即使進行清洗製程，這些可交聯之 .污染物仍不易完全清除。 針對配向處理階段，傳統的刷磨式（rubbing)配向處理係以附 有絨毛刷的滾輪對聚亞醯胺進行刷磨，使聚亞醯胺之高分子主鏈會 延伸而順向排列，達到液晶配向排列的目的。刷磨式配向處理的優 點為刷磨所需之操作時間極短，且在常溫下即可操作，因此具有優 •異之量產特性，然而，傳統的配向方法仍有其缺點，舉例來說，絨 毛刷上無可避免的在製程巾會細污染粒子，間接將此些污染粒子 帶到聚亞醯胺上’造成液晶顯示H顯像產生亮暗不均(mura)。 即使進行祕觸狀触處理，如絲肖⑽伽沾㈣㈣、 離子束配向(ion beam alignment)、電漿束配向(plasma beam alignment) 等處理，可以減少滾輪接觸配向膜之機會，但是這些非接觸式配向 鲁處理仍無法避免塗布製程將可交聯污染物摻雜到配向膜材料的可 月b，且環境中還可能有污染物掉落或接觸至配向膜令。 晴參考第1圖至第3圖，第1圖至第3圖為習知製作顯示面板 的方法示意圖。如第1圖所示，首先提供第一基板1〇，接著於第一 基板10之内表面上形成一層配向膜12，且配向膜12中摻雜了污染 物14。其中，污染物14可能是隨著印刷式塗布處理製程一併轉印 •至第一基板上之可交聯污染物，也可能是利用其他方式掉落至配 - 向膜中之污染物。 201106068 如第2圖所不，之後於第一基板10上滴加液晶材料16，再利 用第3圖所示之步驟進行組裝（assembly)，以組合第一基板1〇與 第一基板18。其中’第二基板18之内表面上亦可先行形成一層配 向膜20 ’且配向膜20亦可能摻雜了污染物14。如第3圖所示，位 於配向膜12與配向膜2G表面之污染物14會受到液晶材料16之張 力影響’因此污染物14容易聚集在液晶材料16之各個小滴的交界 處，而導致亮暗不勻現象（muraeffect)。 尤‘應用至两刀子聚合配向（stabiiize(jaiigj^jent， PSA)裝&時’雖然採用pSA製程之顯示面板可以進行非接觸式配 向處理’但配向膜表面之可交聯污染物卻很容易會影響到液晶材料 中的可又聯單體’使得液晶材料中的可交聯單體與配向膜之污染物 產生反應，導致明顯之亮暗不勻現象。 有鑑於此’如何改善習知的配向膜製程，以減少顯示面板之亮 暗不勻現象，仍為製細示面板之目前之重要課題。 【發明内容】 θ本發明之目的之-在於提供-種製作齡面板之方法，以形成 液晶顯示面板之配向膜，並解決前述習知問題。 201106068 、為達上述目的’本發明之實施例提供一種製作顯示面板之方 法。首先，提供第-基板’接著於第—基板上塗布配向膜材料。其 後，對配向赌料進行蘭烤製程。於觀烤餘之後，對配向膜 材料進行料光處理（uvtrcatme⑷或處理（ρΐ_ ⑽ment) ’以舰摻雜於配向断料中之可交聯污顿^後，提 供第二基板，並於[或第二基板上形成_，然後於第一與第二 基板之間形成液晶層，填充於框膠内。 由於本發啊於職㈣程之後，以及/或形成轉之前，對配 向膜材料進行料光處理或賴處理，鱗化摻雜配向膜材料中 之可交聯污染物’因此可有效減少可交聯污染物導致之亮暗不句現 象。 【實施方式】 為使熟習本發明所屬技術領域之一般技藝者能更進一步了解本 發明’下文特列舉本發明之數個較佳實施例，並配合所附圖式，詳 細說明本發明的構成内容及所欲達成之功效。 請參考第4圖與第5圖，第4圖為本發明第一較佳實施例製作 顯示面板之方法的流程示意圖，而第5圖為根據本發明第一較佳實 施例所製作之顯示面板2〇〇的示意圖。圖式僅以說明為目的，並未 依照原尺寸作圖。 201106068 如第4圖與第5圖所示，莖__^ 弟較佳實施例製作顯示面板的流程 依序如下： 步驟102 :開始； 步驟104 :提供基板； 步驟106 :配向前預清潔（prePlcleaneji);

Description of the Invention: [Technical Field] The present invention relates to a method for fabricating a display panel, and more particularly to a method for performing ultraviolet light treatment or plasma treatment on an alignment film material to passivate cross-linkable contaminants. The method of the panel. [Prior Art] ® Liquid crystal display uses a liquid crystal molecule to control the brightness or color of a display element by different amounts of light in different alignment states, thereby enabling a liquid crystal display to produce a rich image. Therefore, liquid crystal displays usually have an alignment film for causing a liquid crystal molecule adjacent to the alignment film to have a specific alignment direction for regulating the liquid crystal tilting direction in the pixel. The traditional alignment method can be mainly divided into two stages of coating or forming and alignment treatment of the alignment film material, wherein the material of the alignment film is usually polyamide (PI), after the polyimide is coated on the substrate. Then perform the alignment process. For the coating process of the alignment film material, if a conventional transfer coating process is used, the surface of the 'transfer_rintingr〇lier' usually has a photoresist layer for transfer to maintain a good printing effect, and the transfer is light. The photoresist layer on the surface usually does not reach the degree of complete cross-linking, but these incompletely cross-linked photoresists may be transferred to the substrate along with the printing process, 4 201106068, causing contamination. Even if the cleaning process is carried out, these cross-linkable contaminants are not easily removed completely. For the alignment treatment stage, the conventional rubbing alignment treatment uses a roller with a fluff brush to brush the polyamine, so that the polymer backbone of the polyamidene is extended and aligned. The purpose of liquid crystal alignment. The advantage of the brush-type alignment treatment is that the operation time required for brushing is extremely short, and it can be operated at normal temperature, so that it has excellent mass production characteristics. However, the conventional alignment method still has its disadvantages, for example, In the fluffy brush, it is inevitable that the process towel will pollute the particles finely, and indirectly bring the contaminated particles onto the polytheneamine, causing the liquid crystal display H to produce bright and dark unevenness (mura). Even if the secret touch treatment, such as silk ray (10) gamma (four) (four), ion beam alignment, plasma beam alignment, etc., can reduce the chance of the roller contacting the alignment film, but these non-contact The type of alignment treatment still cannot avoid the coating process of doping the crosslinkable contaminants into the alignment film material, and the environment may also have contaminants falling or contacting the alignment film. Referring to Figs. 1 to 3, Figs. 1 to 3 are schematic views showing a conventional method of manufacturing a display panel. As shown in Fig. 1, a first substrate 1 is first provided, then an alignment film 12 is formed on the inner surface of the first substrate 10, and the alignment film 12 is doped with the contaminant 14. Among them, the contaminant 14 may be a cross-linking contaminant that is transferred to the first substrate along with the printing coating process, or may be a contaminant that is dropped into the film by other means. 201106068 As shown in Fig. 2, the liquid crystal material 16 is then dropped on the first substrate 10, and assembly is performed by the steps shown in Fig. 3 to combine the first substrate 1 and the first substrate 18. Wherein the inner surface of the second substrate 18 may also be formed with an alignment film 20' and the alignment film 20 may be doped with the contaminant 14. As shown in Fig. 3, the contaminants 14 on the surface of the alignment film 12 and the alignment film 2G are affected by the tension of the liquid crystal material 16 so that the contaminants 14 tend to collect at the boundary of the droplets of the liquid crystal material 16, resulting in brightening. Darkness phenomenon (muraeffect). Especially when applied to two-knife polymerization alignment (stabiiize(jaiigj^jent, PSA) loading & ' although the display panel using pSA process can perform non-contact alignment treatment', but the cross-linking contaminant on the surface of the alignment film is easy It can affect the recombinable monomer in the liquid crystal material to cause the crosslinkable monomer in the liquid crystal material to react with the contaminant of the alignment film, resulting in obvious bright and dark unevenness. In view of this, how to improve the conventional The alignment film process to reduce the unevenness of the display panel is still an important issue for the production of the thin display panel. [Abstract] θ The object of the present invention is to provide a method for manufacturing an age panel to form The alignment film of the liquid crystal display panel solves the above-mentioned conventional problems. 201106068 A method for manufacturing a display panel is provided for the above-mentioned purposes. First, a first substrate is provided, and then an alignment film is coated on the first substrate. Material. Thereafter, the broking process is carried out on the matching gambling material. After the aging, the aligning film material is light-treated (uvtrcatme (4) or processed (ρΐ_ (10)men t) 'after the doping of the cross-linking in the alignment defect, the second substrate is provided, and _ is formed on the [or second substrate, and then a liquid crystal layer is formed between the first and second substrates Filled in the sealant. Due to the light treatment or treatment of the alignment film material after the service (4), and/or before the formation of the rotation, the cross-linkable pollutants in the scaled doped alignment film material 'Therefore, it is possible to effectively reduce the phenomenon of light and darkness caused by cross-linkable contaminants. [Embodiment] The present invention can be further understood by those skilled in the art to which the present invention pertains. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings in detail. FIG. 4 and FIG. 5, FIG. 4 is a first preferred embodiment of the present invention. A schematic diagram of a method of the method, and FIG. 5 is a schematic view of a display panel 2A made in accordance with a first preferred embodiment of the present invention. The drawings are for illustrative purposes only and are not plotted in accordance with the original dimensions.

In other embodiments, the first substrate 202 may also be an array substrate having a thin film transistor and may have a pixel electrode at the inner surface. Then, according to step 106, a forward pre-cleaning step can be performed, so that the first substrate 2〇2 can have a clean surface, thereby promoting the bonding stability of the first substrate 202 and the subsequent alignment film, and reducing the possibility of contamination of the alignment film. Sex. 201106068 Next, in accordance with step 108, an alignment film material is applied on the first substrate 2〇2, at which time the alignment film material exhibits an unaligned state. Wherein, the alignment film material 11 〇 may comprise a siloxane material material such as polyplyamic acid (pAA) or poly _ (pdyimide ' P〇 material.

When the alignment ruthenium material is formed by the ink-jet coating method, the opportunity for the transfer light or the like to contact the alignment film material and the first substrate 2 〇 2 can be avoided, so that it has a better effect for the purpose of the dyeable material. w Then, according to step 110, the temperature of the pre-bake process of the alignment film material is essentially 5 (rc to wc ^: and = will make:::=:: go to the part of the film material (four) 201106068 After the prebaking process, the alignment film material is passivated according to step ll〇a, such as uv treatment or plasma treatment to purify the doped alignment film. Crosslinkable contaminants in materials, the so-called passivation means that the cross-linking contaminants or other contaminants make it difficult to chemically or physically change, or the chopped contaminants or other contaminants may be cleaved and volatilized. In short, avoid pollution. The object affects the image quality of the liquid crystal display H. In order to passivate the crosslinkable contaminant without destroying or changing the characteristics of the alignment film material, the ultraviolet light intensity of the ultraviolet light treatment of the present invention should preferably be controlled to be greater than per square The centimeters are in the range of milliwatts (〇mW/cm2) and less than or equal to mW/cm2, and the energy intensity should preferably be controlled to be greater than or equal to 3 joules per square centimeter (3 J/cm 2 ) and less than or equal to 30 J/cm 2 , and the wavelength range Better should be controlled Between 300 nm and 450 nm. According to the above process parameters, the alignment film material is continuously subjected to ultraviolet light treatment for about 100 seconds to effectively passivate the crosslinkable contaminant, preferably 150 seconds, but is not limited thereto. The ultraviolet light intensity, energy intensity and wavelength range of the ultraviolet light treatment of the present invention are not limited to the foregoing values as long as the ultraviolet light treatment of the alignment film material has the effect of passivating the crosslinkable contaminants. When plasma treatment is used to passivate crosslinkable contaminants, in order to passivate the conjugateable dyes without destroying the hiding of the alignment stalk, the plasma treatment of the present invention may comprise providing argon (Ar) as an inert gas, vacuum The degree is preferably less than 1 〇·5 Torr (t〇rr) 'The operating power is preferably controlled between 1 watts (1 watts) and 1 watts, the operating temperature is difficult to make the 丨 to 25Gt Preferably, the scale is preferably controlled between about 5 minutes and 120 minutes.

After UV treatment or electric treatment, the alignment film material is post-baking according to step m. The alignment film material is cured and hardened into the alignment film 214, wherein the temperature range of the subsequent baking process is substantially between 3 〇〇 ° C and continues for about _ sec to 10 800 sec. The baking process has a temperature range of preferably 2 to 3 inches and continues for about 1 to 9600 seconds, but is not limited to the baking process. The polyacid amine is imidized into a polyamidamine film. Next, in accordance with step 114, a second substrate 2?6 is provided, and a pre-substrate pre-cleaning step is performed on the first substrate 2?2 and the second substrate 206. The second substrate 2〇6 may have a halogen electrode 208 and an alignment film 216 at the inner surface.
