發明之濾光單元及其製造方法與其應用之顯示面板與顯 示裝置能減輕因為觀看的角度過於偏離時而導致顯示裝 置顯像品質不佳的問題，同時亦不會增加製作的成本。 【實施方式】 以下將參照相關圖式，說明依本發明較佳實施例之一 種濾光單元及其製造方法與其應用之顯示面板與顯示裝 置，其中相同的元件將以相同的符號加以說明。 請同時參照圖2A與圖2B所示，其中，圖2A為本發 明較佳實施例之濾光單元的結構示意圖；圖2B為在不同 寬度之第一遮光層的設置下，濾光單元之視角的變化量。 於此，濾光單元20係與一相位延遲膜40配合應用， 201109788 相位延遲膜40包含有至少一第一相位延遲區42與至少一 第二相位延遲區46，且第一相位延遲區42與第二相位延 遲區46係彼此相鄰。濾光單元20包含一透光基板22、一 光阻層26以及一第一遮光層24。透光基板22具有一第一 表面222與一第二表面224 ;光阻層26設置於第一表面 222，光阻層26係包含至少一第一區域262與至少一第二 區域266，且第一區域262與第二區域266係彼此相鄰， 換句話說，第一區域262與第一相位延遲區42對應設置， * 第二區域266與第二相位延遲區46對應設置；第一遮光 層24設置於第二表面224，且第一遮光層24的投影位置 _ 係位於第一區域262與第二區域266之間的交界，且第r-' 遮光層24在投影方向上係與局部的第一區域262與局部 的第二區域266重疊。 於本實施例中，濾光單元更包含一第二遮光層28設 置於透光基板22之第一表面222，且第二遮光層28更與 φ 局部的第一區域262及局部的第二區域266接觸。 第二遮光層28的投影位置係與第一遮光層24的位置 重疊，其中，第一遮光層24的尺寸係小於或等於第二遮 光層28的尺寸。另，濾光單元20更與一偏光膜50配合 應用，於此，偏光膜50係設置於透光基板22與相位延遲 膜40之間為例說明，然不以此為限。 更詳細來說，上述的透光基板22可為玻璃基板、塑 料基板或任何可透光材質所構成的基板。光阻層26之第 一區域262或第二區域266可選自紅色、綠色、藍色或上 201109788 述的組合所構成之色彩光阻層。而光阻層26、第二遮光層 28或第一遮光層24的材料可選自於負型光阻材料或正型 光阻材料，且上述之光阻層26、第一遮光層24或第二遮 光層28均可利用微影製程（photolithigraphy)以形成於透 光基板22上。 本發明在基於上述的結構，當濾光單元之透光基板22 的厚度等於500微米（#m)，第二遮光層28的寬度為50 微米，偏光膜50的厚度等於200微米，且濾光單元20與 偏光膜50的折射係數均等於1.5時，於此，在相同條件下， 濾光單元20於未設置有第一遮光層24時，如習知架構， 其視角（Θ ) = 6.13786。然而，以本發明之架構且當第一 遮光層24的寬度在15微米時，本發明之視角（Θ ')開始 有增加的現象，另當第一遮光層24等於第二遮光層28的 寬度（50微米）時，視角（6^)可增加至3倍以上，如 圖2B所示。 更詳細來說，本發明之第一遮光層24的尺寸係在不 影響濾光單元20之開口率的前提下所設置，亦即，第一 遮光層24的尺寸必須小於等於第二遮光層28的尺寸，也 就是說，在開口率維持不變的情況下，應用此濾光單元20 之顯示面板或顯示裝置可大幅增加訊號顯示的視角，且不 會影響其顯示的亮度。 請參照圖3所示，其為本發明較佳實施例之另一種濾 光單元的結構示意圖。濾光單元20'與上述濾光單元20不 同之處在於：濾光單元2(V其透光基板22之第一表面222 201109788 係不具有如上所述之第二遮光層（黑色矩陣層）的設置， 而設置於第二表面224之第一遮光層24的投影位置係位 於第一區域262與第二區域266之間的交界，且第一遮光 層24在投影方向上係與局部的第一區域262與局部的第 二區域266重疊。 由於第二遮光層（黑色矩陣層）是以不透光的特性以 將光阻層之26第一區域262或第二區域266作分隔，其 目的在於降低不同色光之間干擾的程度。然而，當訊號通 過光阻層26 (例如：第一區域262與第二區域266之間的 界面）時，因第一遮光層24的設置，其仍具有遮光的特 性，亦能降低不同色光之間的干擾，故本發明之濾光單元 20’可在無須第二遮光層（黑色矩陣層）之設置且不影響色 光的出光效果之前提下，亦能達到增加視角的效果。 請參照圖4所示，本發明較佳實施例之一種濾光單元 的製造方法包含步驟S11至步驟S13,並請同時參照圖2A 與圖4所示，以進一步說明濾光單元20的製造方法。 首先，步驟S11為提供一透光基板22，透光基板22 具有一第一表面222與一第二表面224;步驟S12於第一 表面222形成至少一第一區域262與至少一第二區域266 以構成一光阻層26，形成的第一區域262與第二區域266 係彼此相鄰；步驟S13則為於第二表面224形成一第一遮 光層24，且形成第一遮光層24的投影位置係位於第一區 域262與第二區域266之間的交界，並與局部的第一區域 262及局部的第二區域266重疊。於此，在步驟S12與步 11 201109788 驟S13之間更包含一翻轉透光基板22的步驟（圖未顯示）。 其中，在步驟S12中形成第一區域262與第二區域266 (光阻層26)的方法與形成第一遮光層24 (步驟S13)的 方法係藉由塗佈一光阻材料（例如：負型光阻或正型光阻） 以實現，在再利用一光罩（圖未顯示）對上述光阻材料進 行圖案化的步驟，此為一微影製程，於此不再贅述。 此外，在形成第一區域262與第二區域266前（步驟 S12)更先於第一表面222上形成一第二遮光層28，且形 成第二遮光層28的方法係藉由塗佈以實現（更包含圖案 化第二遮光層28)，值得注意的是，形成第二遮光層28的 投影位置係與第一遮光層24的位置重疊，換句話說，透 光基板22可已具有第二遮光層28設置於第一表面222， 且第一區域262與第二區域266係受到第二遮光層28所 間隔。 值得注意的是，形成第二遮光層28、光阻層26與第 一遮光層24的順序並不以上述的步驟為限，形成第一區 域262與第二區域266以構成光阻層26於第一表面222 的步驟（步驟S12)更可執行在形成第一遮光層24於第二 表面224上的步驟（步驟S13)之後，即，形成第一遮光 層24 (步驟S13)或光阻層26 (步驟S12)的順序亦不影 響本發明之增加視角的目的。本發明亦可於透光基板22 的表面（例如：第二表面224 )先形成第一遮光層24後， 再將已具有第一遮光層24的透光基板22翻轉至另一表面 (例如：第一表面222 )再進行形成光阻層26於此第一表 12 201109788 面222，換言之，本發明揭露的濾光單元20在製程上僅需 形成一第一遮光層24與一光阻層26於透光基板22的兩 側。另，本發明之濾光單元20在步驟Sll t並不以已具 有第二遮光層28設置的透光基板22為限，本發明之濾光 單元20無須第二遮光層28之設置亦可達到增加視角的效 果，故本發明之濾光單元20其無須增加製程的步驟，即， 省略形成第二遮光層28的步驟（如圖3所示），亦能減輕 因為觀看的角度過於偏離時而導致顯示裝置顯像品質不 ®佳的問題。 請參閱圖5所示，本發明較佳實施例之一種顯示面板 ' 之結構示意圖。顯示面板80包含一顯示單元70及一濾光 ' 單元20。濾光單元20與顯示單元70對應設置。值得注意 的是，本實施例之顯示面板80雖以包含濾光單元20為例 說明，但亦可依實際需要以上述之濾光單元20’為例。於

The photoresist layer 26 is disposed on the first surface 222. The photoresist layer 26 includes at least a first region 262 and at least a second region 266. A region 262 and a second region 266 are adjacent to each other. In other words, the first region 262 is disposed corresponding to the first phase retardation region 42, and the second region 266 is disposed corresponding to the second phase retardation region 46; the first light shielding layer 24 is disposed on the second surface 224, and the projection position _ of the first light shielding layer 24 is located at a boundary between the first region 262 and the second region 266, and the r-th light shielding layer 24 is partially and partially in the projection direction. The first region 262 overlaps the local second region 266. In this embodiment, the filter unit further includes a second light shielding layer 28 disposed on the first surface 222 of the transparent substrate 22, and the second light shielding layer 28 further includes a first region 262 and a partial second region. 266 contacts. The projection position of the second light shielding layer 28 overlaps with the position of the first light shielding layer 24, wherein the size of the first light shielding layer 24 is smaller than or equal to the size of the second light shielding layer 28. Further, the filter unit 20 is further used in combination with a polarizing film 50. Here, the polarizing film 50 is disposed between the transparent substrate 22 and the phase retardation film 40 as an example, but is not limited thereto. More specifically, the above-mentioned transparent substrate 22 may be a glass substrate, a plastic substrate or a substrate made of any light transmissive material. The first region 262 or the second region 266 of the photoresist layer 26 may be selected from the group consisting of red, green, blue, or a color photoresist layer formed by the combination of the above. The material of the photoresist layer 26, the second light shielding layer 28 or the first light shielding layer 24 may be selected from a negative photoresist material or a positive photoresist material, and the photoresist layer 26, the first light shielding layer 24 or the The two light shielding layers 28 can all be formed on the light transmissive substrate 22 by photolithography. According to the above structure, when the thickness of the light-transmitting substrate 22 of the filter unit is equal to 500 μm (#m), the width of the second light-shielding layer 28 is 50 μm, the thickness of the polarizing film 50 is equal to 200 μm, and the filter is filtered. When the refractive index of the unit 20 and the polarizing film 50 are both equal to 1.5, under the same conditions, the filter unit 20 is not provided with the first light shielding layer 24, and the viewing angle (Θ) is 6.13786. However, with the architecture of the present invention and when the width of the first light-shielding layer 24 is 15 μm, the viewing angle (Θ ') of the present invention begins to increase, and when the first light-shielding layer 24 is equal to the width of the second light-shielding layer 28 (50 μm), the viewing angle (6^) can be increased by more than 3 times, as shown in Fig. 2B. In more detail, the size of the first light shielding layer 24 of the present invention is set without affecting the aperture ratio of the filter unit 20, that is, the size of the first light shielding layer 24 must be equal to or smaller than the second light shielding layer 28. The size, that is, the display panel or the display device to which the filter unit 20 is applied can greatly increase the viewing angle of the signal display without affecting the brightness of the display. Please refer to FIG. 3, which is a schematic structural view of another filter unit according to a preferred embodiment of the present invention. The filter unit 20' is different from the above-described filter unit 20 in that the filter unit 2 (V, the first surface 222 of the transparent substrate 22, 201109788 does not have the second light shielding layer (black matrix layer) as described above) The projection position of the first light shielding layer 24 disposed on the second surface 224 is located at a boundary between the first region 262 and the second region 266, and the first light shielding layer 24 is partially first in the projection direction. The region 262 overlaps with the local second region 266. Since the second light shielding layer (black matrix layer) is characterized by being opaque to separate the first region 262 or the second region 266 of the photoresist layer 26, the purpose is to The degree of interference between different colored lights is reduced. However, when the signal passes through the photoresist layer 26 (for example, the interface between the first region 262 and the second region 266), it still has blackout due to the arrangement of the first light shielding layer 24. The characteristics of the light source can also reduce the interference between different color lights, so the filter unit 20' of the present invention can be provided without the need to set the second light shielding layer (black matrix layer) without affecting the light output effect of the color light. Increase the effect of the angle of view Referring to FIG. 4, a method for manufacturing a filter unit according to a preferred embodiment of the present invention includes steps S11 to S13, and please refer to FIG. 2A and FIG. 4 simultaneously to further explain a method for manufacturing the filter unit 20.

The projection position is located at the boundary between the first region 262 and the second region 266, and overlaps with the partial first region 262 and the partial second region 266. Here, between step S12 and step 11 201109788 step S13 The method includes a step of turning over the transparent substrate 22 (not shown). The method of forming the first region 262 and the second region 266 (the photoresist layer 26) and forming the first light shielding layer 24 in step S12 (step S13) By coating a photoresist material For example, a negative photoresist or a positive photoresist is used to realize the step of patterning the photoresist material by using a photomask (not shown), which is a lithography process, and details are not described herein. In addition, a second light shielding layer 28 is formed on the first surface 222 before the first region 262 and the second region 266 are formed (step S12), and the method of forming the second light shielding layer 28 is performed by coating. (more including the patterned second light shielding layer 28), it is noted that the projection position of the second light shielding layer 28 is overlapped with the position of the first light shielding layer 24, in other words, the transparent substrate 22 may already have the second The light shielding layer 28 is disposed on the first surface 222, and the first region 262 and the second region 266 are spaced apart by the second light shielding layer 28.

In the present invention, after the first light shielding layer 24 is formed on the surface of the transparent substrate 22 (for example, the second surface 224), the transparent substrate 22 having the first light shielding layer 24 is turned over to another surface (for example: The first surface 222 is further formed to form the photoresist layer 26 on the first surface 12 201109788 surface 222. In other words, the filter unit 20 disclosed in the present invention only needs to form a first light shielding layer 24 and a photoresist layer 26 in the process.
