Description of the Invention: [Technical Field of the Invention] The present invention relates to a color filter, and more particularly to a color filter capable of reducing material cost and manufacturing steps Manufacturer's method, and color filters made using this method. [Prior Art] Liquid crystal display (LCD) has low operation f) voltage, no radiation scattering, light weight and small size, and can not be achieved by conventional cathode ray tube (CRT) Advantages, therefore, liquid crystal displays have become a major subject of display research in recent years' and are moving toward colorization. Most of the color-changing liquid crystal displays use a combination of a backlight module (BLM) and a color filter (color fllter) to achieve colorization. The structure of the color filter is generally as shown in FIG. Figure 1 is a schematic cross-sectional view of a color filter. Referring to FIG. 1, a red color block 丨2, a green color block 14, and a blue color block 16 are arranged side by side on a glass substrate 10. A black matrix ι8 is arranged between the color blocks. Further, the substrate has a layer of indium tin oxide (ITO) transparent electrode 11. The color filter is usually produced by first coating a black photosensitive resin material on the glass substrate 1 . Then, a yellow lithography process such as exposure, development, hard baking, or the like is performed using a photomask to form a black matrix 18. Then, the red (8), green (G), and blue (B) patches 12, 14, and 16 are formed by the method of yellow lithography, and the patches 12, 14, and 16 are evenly arranged in the black matrix 18. On the opening area 18a. After 5,200837400 95604 21863twf.doc/n, the indium tin oxide transparent electrode U is deposited on the glass substrate 1 to complete the color filter and the light sheet. • However, in the actual process of color filters, there is often a cross-wall phenomenon in which the color blocks 12, 14, 16 are mixed across the black matrix 18. This cross-wall phenomenon not only causes the black matrix to cover the color block area and affects In addition to the display, if the phenomenon of cross-wall is serious, there will be a "horn area" 17 generated, that is, as shown in Fig. 1, the green color block 14 and the top surface of the blue color block 16 will have an intermediate depression.
〇 邊緣尖突的情形,此現象更將使後續的導電層披覆不良而 降低良率。 K 為了避免導電層披覆不良而降低良率,通常在形成色 塊12、14、16之後,還會於玻璃基板1〇〇上塗佈一層表面 平整的披覆層19。然而,披覆層19覆蓋於色塊12、14、 16與黑色矩陣18上,會造成無法預測的RGB色間差出 現,也會增加彩色濾光片的製程複雜性。 此外,為了減少生產成本,習知另一種形成彩色滤光 片的方法是先形成黑色矩陣18做為屏障 C 的方法以形成色塊12、14、16。為了容置顏料及避免混 1, 因此黑色矩陣18的厚度較色塊12、14、16其中任一為厚。 • 但是,、因,喷墨技術的喷頭對準問題以及目前液晶顯示器 所追求的南解析度(思即小像素),反而會有顏料喷塗不易 及生產製程良率低的問題。 【發明内容】 本發明之目的是提供一種可以減少材料使用量之彩 濾光片的製作方法。 6 200837400 95604 21863twf.doc/n 本發明之另-目的是提供一種製程複雜度低且製程問 題較少之彩色濾光片的製作方法。 口-i發,ΐ另一目的是提供—種製程成本低且具有較高 口口質的形色濾光片。 制ί達上核是其他目的,本發明^—種彩色濾光片 的衣作方法,包括下列之步驟。首先,提供—透明基板, 巧剌基板至=有—可視區。然後,在透明基板上塗佈 ^第一:第二及第三感光材料,以於透明基板上形成多個 第一、第二及第三色塊。之後,選擇將第一、第二或第三 感光2料塗佈於透明基板之週邊,以形成一障壁作妨幻, 其中第一、第二及第三色塊皆位於障壁内。然後,利用噴 墨法將^色矩陣材料喷塗於第―、第二及第三色塊及障壁 間,並藉由其流動性均勻分佈在透明基板上,並形成一黑 矩陣。 在本發明之一實施例中,於形成黑矩陣後,更包括於情形 In the case of sharp edges, this phenomenon will make the subsequent conductive layer drape and reduce the yield. In order to prevent the conductive layer from being poorly coated and to reduce the yield, a flat surface coating layer 19 is usually applied to the glass substrate 1 after the formation of the color blocks 12, 14, and 16. However, the cladding layer 19 covers the color patches 12, 14, 16 and the black matrix 18, which causes an unpredictable RGB color difference to appear, which also increases the process complexity of the color filter. Further, in order to reduce the production cost, another conventional method of forming a color filter is to first form a black matrix 18 as a barrier C to form color patches 12, 14, 16. In order to accommodate the pigment and avoid mixing 1, the thickness of the black matrix 18 is thicker than any of the patches 12, 14, 16. • However, due to the problem of nozzle alignment in inkjet technology and the south resolution (think of small pixels) currently pursued by liquid crystal displays, there is a problem that pigment coating is difficult and production process yield is low.

In one embodiment of the invention, the material of the color patch is a color photoresist material. In one embodiment of the invention, the color photoresist material is selected from the group consisting of a red photoresist, a green photoresist, and a blue photoresist. The color filter invented by the company and the manufacturing method thereof are characterized in that after forming the first and third color blocks, the first, second or third photosensitive material is selected, and the second substrate is formed on the J-shaped substrate to surround the first The second and third color block barriers can be used to form a black matrix on the substrate due to the spread of the spacers. Therefore, it is possible to reduce the material of the black matrix and simplify the process of the color filter. The above and other objects, advantages and advantages of the present invention will become more apparent from the following description. FIG. 3A to FIG. 3E are flowcharts showing the cross-section of the color filter of FIG. 2. Referring to Figure 2, and referring to Figures 3A to 3E in sequence, first, as shown in Figure 9A, the present invention provides a transparent substrate 100 in which the transparent substrate 100 has a visible area 100a and a non-visible area 1 Then, a photosensitive material is coated in the visible region 100a of the transparent substrate 1 , and the photosensitive material may be a photosensitive material of one of two colors of red, green and blue. The photosensitive material is pre-baked, and the pre-baked photosensitive material is exposed, developed and hard-baked by a mask 200 to be patterned to form a color patch 110. In this embodiment, the color block is formed. 11〇 may be a red color block. ζχ Next, as shown in step S110, FIGS. 3A and 3C, a photosensitive material different in color from the above-mentioned photosensitive material, for example, a green and blue photosensitive material, is coated on the transparent substrate 100. In the area l〇〇a, and repeating the above steps 'to form different color patches 120, 130. In this embodiment, the color block 120 may be a green color block, and the color block 130 may be a blue color block. When presented individually, red, green, and blue The color blocks 11〇, 12〇, 130 are arranged in an array on the transparent substrate 100, as shown in Fig. 4. Then, the photosensitive material of one of the above three colors is selected as in step S120', and the photosensitive material is coated.

之後如步驟S130及圖3D示,使用噴墨法於透明基板 100上形成一黑矩陣150。詳細地來說,是利用一喷墨頭 300將黑色感光樹脂材料噴灑於色塊11〇、120、130之間 的空隙,以及最外圍的色塊110、120、130與障壁140之 間的空隙(如圖4示),使黑色感光樹脂材料漫佈於空隙間。 黑色感光樹脂材料乾燥後會在透明基板100上形成一將色 塊110、120、130加以區隔的黑矩陣150。 特別的是 田%黑巳啟无樹脂材料為液狀,因此黑色 感光樹脂材料可以快速地流動擴散,因而黑矩陣15〇能夠 具有良好的平整度。更進一步地來解釋,使用喷墨法喷塗 黑色感光樹脂時’各個色塊11〇、12〇、13〇及障壁mo之 間的空隙為相互連通的開放空間,因此黑色感光樹脂材料 可以均勻地流通分佈在透明基板100上,且不會因為喷墨 技術及精準度的影響而受限,因此可喊少製㈣複雜度 及增加生產良率。此外,與習知顯影製程來形成黑矩 陣相較’使时墨法來形成黑矩陣15〇,可以減少光罩的 使用,並簡化製程步驟。 黑色感光樹脂材料費用較形成色塊110、 、13G的感光材料費用高,因此本 塊加、12〇或13。的感光材料來形= 、色感光樹脂材料的使用量,節省材料成本。 值得注意的是’與f知喷墨法她,本發 減的色塊作為黑矩陣材材料流動的屏障。因此,藉由控 200837400 95604 21863twf.doc/n 制噴墨頭3GG的噴墨量,可使黑矩陣15()的厚度低於或等 於色塊11G、12G、130的厚度。尤有甚者,藉由控制喷墨 f 300的噴墨量,不但可以使黑矩陣15()的厚度較薄以節 省材料成本,更可以藉由控制黑矩陣15〇的厚度進而決定 . 舰陣15G的遮光影響範圍,制用本發明之彩色濾光片 的衣作方法所製作出來的彩色濾光片,具有較習知良好的 光利用效率。 此外,與曝光顯影彩色濾光片製程的彩色濾光片相 車乂,本發明係藉由將黑色感光樹脂喷佈在色塊及障壁間的 空間,所以在製程中不會產生色塊與黑矩陣的跨牆現象, 進而讓彩色濾光片具有良好的開口率。 最後,如步驟S140及圖3Ε示,利用物理氣相沉積法 在色塊110、120、130及黑矩陣150上形成一透明電極層 16〇 ’便完成彩色濾光片400的製作。在本實施例中,此物 理氣相沉積法為濺鍍。此外,在形成透明電極層16〇之前, 也可以選擇性地在色塊110、120、130及黑矩陣150上先 ^ 形成一表面平整的彼覆層152,以使之後形成於彼覆層152 表面上的透明電極層160能夠具有均勻的厚度及平坦的表 面。值得一提的是,因為本發明係藉由將黑色感光樹脂嘴 佈在色塊間的空間’所以在製程中不會產生色塊與黑矩陣 的跨牆現象,所以更有利於此透明電極層16〇彼覆的製 程’進而提高彩色濾光片的良率,同時可以減少彼覆層152 的製程步驟,減少製程的複雜度。 4寸別的是’經由控制黑色感光樹脂材料的量,於本發 12 200837400 95604 21863twf.doc/n 明之彩色濾光片_中’可以形成厚度較習知之喷墨法所 =成的彩色濾光片薄的黑矩陣150,因此被黑矩陣150遮 敝=:交習知少,讓使用本發明之彩色濾光片 不為具有較高的光利用率。 、、、1*上所14本U之彩色濾的製作方法是利用喷 ί法來形成黑矩陣,不但可以減少光罩的使用、簡化製程 c雜度’還可以節省材料成本,更可以進_步的提Thereafter, as shown in steps S130 and 3D, a black matrix 150 is formed on the transparent substrate 100 by an ink jet method. In detail, a black photosensitive resin material is sprayed on the gap between the color patches 11 〇, 120, 130 by an ink jet head 300, and a gap between the outermost color patches 110, 120, 130 and the barrier rib 140 is used. (As shown in Fig. 4), a black photosensitive resin material is spread between the gaps. After the black photosensitive resin material is dried, a black matrix 150 which separates the color blocks 110, 120, 130 is formed on the transparent substrate 100. In particular, the field-free black resin material is liquid, so that the black photosensitive resin material can flow and diffuse rapidly, so that the black matrix 15 〇 can have a good flatness. To further explain, when the black photosensitive resin is sprayed by the inkjet method, the gaps between the respective color patches 11〇, 12〇, 13〇 and the barrier mo are open spaces that communicate with each other, so that the black photosensitive resin material can be uniformly The circulation is distributed on the transparent substrate 100, and is not limited by the influence of the inkjet technology and the accuracy, so that the system can be shouted less (four) complexity and increased production yield. In addition, the conventional method of forming a black matrix to form a black matrix 15 〇 can reduce the use of the mask and simplify the process steps. The cost of the black photosensitive resin material is higher than that of the photosensitive material forming the color patches 110, 13G, so the block is added, 12 〇 or 13. The photosensitive material is used to form the amount of photosensitive resin material used, which saves material cost. It is worth noting that, with the fact that she knows the inkjet method, the color block that is reduced is used as a barrier for the flow of the black matrix material. Therefore, by controlling the ink ejection amount of the ink jet head 3GG of 200837400 95604 21863 twf.doc/n, the thickness of the black matrix 15 () can be made lower than or equal to the thickness of the color patches 11G, 12G, 130. In particular, by controlling the amount of inkjet f 300, not only can the thickness of the black matrix 15 () be thinner to save material cost, but also can be determined by controlling the thickness of the black matrix 15 .. The color filter of 15G has a better light utilization efficiency than the color filter produced by the coating method of the color filter of the present invention. In addition, in contrast to the color filter of the exposure and development color filter process, the present invention does not generate color patches and blacks in the process by spraying a black photosensitive resin between the color block and the barrier. The cross-wall phenomenon of the matrix allows the color filter to have a good aperture ratio. Finally, as shown in step S140 and Fig. 3, the formation of the color filter 400 is completed by forming a transparent electrode layer 16?' on the patches 110, 120, 130 and the black matrix 150 by physical vapor deposition. In this embodiment, the physical vapor deposition method is sputtering. In addition, before the transparent electrode layer 16 is formed, a surface layer 152 may be selectively formed on the color blocks 110, 120, 130 and the black matrix 150 so as to be formed on the cladding layer 152. The transparent electrode layer 160 on the surface can have a uniform thickness and a flat surface. It is worth mentioning that, because the invention provides a black photosensitive resin nozzle in the space between the color blocks, the cross-wall phenomenon of the color block and the black matrix does not occur in the process, so that the transparent electrode layer is more advantageous. The 16-pass process further increases the yield of the color filter, while reducing the process steps of the overlay 152 and reducing the complexity of the process. The 4 inch is 'by controlling the amount of the black photosensitive resin material, in the color filter _ in the '12 200837400 95604 21863 twf. doc / n can be formed into a color filter than the conventional inkjet method = The thin black matrix 150 is thus concealed by the black matrix 150 =: less knowledge, so that the color filter using the present invention does not have a high light utilization efficiency. The method of making 14 U color filters on the 1st is to use the spray method to form the black matrix, which not only reduces the use of the mask, but also simplifies the process c noise. It also saves material costs, and can also enter _ Step mention
