200848773 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種顯示裝置，尤其係關於一種顯示裝置之光 學膜及其製造方法。雖然本發明實施例適合廣泛範圍的應用，但 是尤其適用於改善抗刮、防污（anti-fouling)以及抗反射特性。 【先前技術】 顯示裝置例如電聚顯示面板（plasma display panel; PDP )、電 場發光顯示器（electroluminescent display ; ELD)以及液晶顯示哭 (liquid crystal display ; LCD)等由於具有響應速度快、功率消耗 低以及色彩再現率高的特點已經受到眾多關注。這種顯示裝置用 於多種家庭應用，包含電視、電腦監視器、筆記型電腦、行動電 活、冰箱之顯示器等。尤其近年來，例如允許透過使用觸控螢幕 而輸入資訊之個人數位助理（personaldigitalassistant ; pDA：)、自 動櫃員機（automated teller machine; ATM)等顯示裝置現在正被 普遍使用。 顯示裝置中，抗眩（anti-glare)膜、偏光器、稜鏡片等光學膜 接合至背光單元或顯示φ板，赠止外部光線的傳輸和反射所帶 來的對比度下降，防止影像反射，並且保護螢幕。尤其地，在窄 示裝置的表面上透過直接地接觸使用者的手或者針筆而輪入資 訊，對於具有此種功能的顯示裝置來說，因為使用者的手或者針 筆的觸壓，光賴需要具有很高的抗指紋或者抗模糊能力，或者 6 200848773 需要具有能夠清除指紋或消除模糊的能力，即具有防污特性。 習知技術中，具有相對高表面能(surface energy)(大約4〇毫 牛頓/米〜50毫牛頓/米）之丙烯酸聚合體（acrylic p〇lymer)材 料置於顯示裝置之螢幕之上。因此，丙烯酸聚合體與污染物強烈 地交互作用（即，強烈地吸引污染物），從而很容易黏著污染物於 螢幕之上。當污染物黏著至螢幕上的丙烯酸聚合體材料時，很難 從螢幕上擦除污染物，並且當嘗試擦拭螢幕時，螢幕可能被污染 物刮划。此外，因為背光單元巾使用的稜鏡片具有尖端部和底部 之形狀，所以尖端部容易被外力損壞或磨損。 【發明内容】 因此，本發明實施例之目的在於提供一種顯示裝置之光學膜

Description of the Invention: [Technical Field] The present invention relates to a display device, and more particularly to an optical film of a display device and a method of manufacturing the same. While embodiments of the present invention are suitable for a wide range of applications, they are particularly useful for improving scratch, anti-fouling, and anti-reflective properties. [Prior Art] Display devices such as a plasma display panel (PDP), an electroluminescent display (ELD), and a liquid crystal display (LCD) have high response speed and low power consumption. The high color reproduction rate has received a lot of attention. Such display devices are used in a variety of home applications, including televisions, computer monitors, notebook computers, mobile computers, displays for refrigerators, and the like. In particular, in recent years, display devices such as personal digital assistants (pDA:) and automated teller machines (ATM) that allow information to be input by using a touch screen are now in widespread use. In the display device, an optical film such as an anti-glare film, a polarizer, or a cymbal is bonded to a backlight unit or a φ plate, which suppresses contrast reduction caused by transmission and reflection of external light, and prevents image reflection, and Protect the screen. In particular, the information is wheeled on the surface of the narrow display device by directly contacting the user's hand or the stylus pen. For a display device having such a function, the light is pressed by the user's hand or the stylus pen. Lai needs to have high anti-fingerprint or anti-blur capability, or 6 200848773 needs to have the ability to remove fingerprints or eliminate blur, that is, anti-fouling properties. In the prior art, an acrylic p〇lymer material having a relatively high surface energy (about 4 Torr/m to 50 mA/m) is placed on the screen of the display device. As a result, acrylic polymers interact strongly with contaminants (i.e., strongly attract contaminants), making it easy to adhere contaminants to the screen. When contaminants adhere to the acrylic polymer material on the screen, it is difficult to remove contaminants from the screen, and when attempting to wipe the screen, the screen may be scratched by contaminants. Further, since the cymbal sheet used in the backlight unit has the shape of the tip end portion and the bottom portion, the tip end portion is easily damaged or worn by an external force. SUMMARY OF THE INVENTION Accordingly, it is an object of embodiments of the present invention to provide an optical film of a display device and a method of fabricating the same that substantially obviate one or more of the problems of the limitations and disadvantages of the prior art.

The purpose of this fortune _ and other advantages: 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀 亀In order to obtain these and other features of the present invention, the present invention is embodied and diversified, and the surface of the invention comprises: a substrate; and a coating layer, wherein the first material has a first range a surface energy value, the second material has a surface energy value of the second range, and the surface energy value of the second range is smaller than the surface of the first range. The value of the read first material is mainly distributed on the first side of the coating layer contacting the substrate. The second material is mainly distributed over the second side of the coating layer opposite the first side. On the other hand, the optical axis of the device includes m and a coating layer, and the material and the surface of the device are combined with each other, so that the material of the biasing material is mainly disposed on the first side of the coating layer contacting the substrate. The non-biased material is mainly distributed on the second side of the coating layer opposite to the first side. The method for producing an optical film comprises: adding a polymerization initiator, one of a monomer (m〇nomer) or an oligomer (〇lig〇mer) to form a polymer tree, mixing a polymer resin and containing fluorine and The compound is lightly reduced to obtain a coating solution of 200848773; and a coating is provided on the substrate such that the polymerization moves away from the substrate to form a phase separation of the compound of the pure fluorine and Wei Shaoqi. It is to be understood that the description of the invention as described above and the following description of the present invention are both representative and explanatory, and are intended to further disclose the scope of the invention.

'Therefore preventing the smudge from joining to its surface. That is to say, if the surface energy of a certain material is high, the force of the shot is increased, thereby enhancing the absorption characteristics of different materials. If the surface energy is low, the attraction of the shot is lowered, thereby reducing the absorption of different materials. The exposed face of the optical film is set to have a low surface energy, and the joint face is set to have a high surface energy. For this purpose, the membrane of the prior art comprises a two-layer structure for use, the towel having a high surface energy feed joint to the side, and the material having a low surface energy bonded to the other side. ^ In contrast to the target material, the present invention provides a single-layer silk film which is permeable to and smeared, and each of which contains a non-surface energy body = contact angle or surface.撼 silk scarf, and the cloth is produced (4) on the heart of 200848773, without the need to undergo an additional process of joining the two films, so that the manufacturing process can be simplified and the optical film can have good scratch resistance, antifouling and pollutant removal properties. . That is, depending on the difference in surface energy value, the difference between the contact angles in the _ state, or the difference between the two riding materials that make up the optical film, the _ real complement recognizes the phase separation (fine e-separation) effect and the resistance. Scratch, antifouling and contaminant removal characteristics are different. The factors used in the effective phase separation in the embodiment of the present invention are as follows. The optical axis feather of the invention is applied to the apparent resistance of the pair of towels, the anti-glare film, the anti-reflection film, the polarizer or the bracts.

Therefore, the optical film of the embodiment of the present invention can have improved scratch resistance, antifouling and antireflection properties enough to tolerate scratches caused by external pressure. The "second diagram", "second diagram", "second diagram", "second diagram" and "second diagram" are schematic diagrams showing the manufacturing process of the optical film of the embodiment of the present invention. First, as shown in Fig. 2a, in order to produce the optical film 15, the polymerization initial d(B) is added to the monomer (mon) or the oligomer (a) to form the polymer resin 110.

Referring to Fig. 8, the optical raft of the sixth embodiment of the present invention comprises a coating layer 75G formed on the base layer (4). The coating layer 75G may be a highly reflective film containing a polymer resin 71 〇 and a fluorine-containing and/or chopped compound 730, and contains a concave-convex surface. The density of the fluorine-containing and/or the compound in the upper surface layer of the coating layer 750 contacting the base layer 800 is higher than the density of the fluorine-containing and/or antimony compound 73 in the lower surface layer of the coating layer 750. Therefore, the optical film of the sixth embodiment of the present invention can have excellent scratch resistance, antifouling and antireflection properties. The base layer used in the above embodiment may be one of a diffuser plate, a polarizer, a display screen, and a enamel layer. In addition to the above embodiments, the polarizer may include a base film, a polarizing film, and a second base film. Here, the base film may be a cellulose diacetate film, and the polarizing film may comprise polyvinyl alcohol. The second base film may comprise a cellulose triacetate film and a fluorine-containing and/or rhodium-containing compound.

The "Fig. 9a" and "%" diagrams are cross-sectional views of the cymbal of the embodiment of the present invention. Referring to "Fig. 9a", the cymbal includes a base 92 and a weir 910 formed on the base 920. Substrate 920 comprises polyethylene terephthalate (PET)' but is not limited thereto. Polyethylene terephthalate (pET) is a film that is entangled in the plastic tree, and has excellent electrical properties and can be used as a very thin film. In addition, polyethylene terephthalate (PET) is very suitable for use as a wafer because polyethylene terephthalate (PET) has excellent heat-resistance and transparency.

The crotch portion 910 is placed on the base 920 and passes through the coating layer 15 shown in "%", "figure", "2C", "2d" and "2e". The same method is prepared. Therefore, detailed descriptions thereof are omitted to avoid repetition of the description. The "figure % map" is a cross-sectional view of a septum including a branch portion 93 placed between the base 92 and the crotch portion. The branch portion 93 reads the prism portion. The prism lens 900 described above can be applied to a backlight unit of a display device. 21 200848773 A "cross-sectional view" of a backlight unit having a cymbal according to an embodiment of the present invention. Generally, the backlight unit is separated into an edge type and a direct type backlight unit in accordance with the position of the fluorescent lamp. Although the "Fig. 10" shows an edge type backlight unit, the embodiment of the present invention can be applied to a direct type backlight unit. As shown in FIG. 10, the edge type backlight unit 1000 includes a reflection sheet 1010, a light source unit, a light guide plate 1〇4〇, a diffusion sheet 1〇2〇, a cymbal sheet 9〇〇, and a protective sheet 1〇3〇. The light source portion that emits light includes at least one fluorescent lamp 1〇6〇 and a cover 1〇5〇 for receiving the fluorescent lamp 1060. The light source may comprise a cold cathode fluorescent lamp (c〇ld cath〇de fluorescent lamp) or a light emitting diode instead of a fluorescent lamp. The cover 1050 receives the fluorescent lamp 1〇6〇 and reflects the light from the fluorescent lamp 1〇6〇. The light guide plate 1040 controls the light from the light source portion, uniformly diffuses the light, and guides the diffused light to the display panel. The reflection sheet 1010 reflects the light from the light guide plate 1040 to the light guide plate 1040. The diffusion sheet 1020 diffuses or polymerizes light from the light guide plate 1〇4〇 and the reflection sheet 1010. The wafer 900 polymerizes a portion of the light that is polymerized or diffused by the diffusion sheet 1020 to the protective sheet 1030, and reflects the residual light to the light guide plate 〇40. The cymbal sheet 900 is formed on the base 920 or the support portion 930 as shown in "Fig. 9a" and "%". The protective sheet 1030 diffuses the light condensed by the cymbal 900 and provides this light to the display panel to expand the viewing angle of the display panel. The direct type backlight unit (not shown) is different from the edge type backlight unit in that a fluorescent lamp is placed between the diffusion sheet and the reflection sheet. Therefore, the direct type backlight unit does not need to have a light guide plate.

The color filter includes a red fluorescent sheet R, a green color filter G, and a blue color filter B, and each color filter produces a corresponding color when light is applied thereto. The common electrode 1160 and the halogen electrode 1150 are arranged in the liquid crystal layer 1170 in accordance with a voltage applied from the outside. The halogen electrode 115 is switched through the thin film transistor 114A. The liquid crystal layer 1170 contains a plurality of liquid crystal molecules, and the axis of the liquid crystal molecules is aligned in one direction through the voltage difference between the halogen electrode 1150 and the common electrode H60. Therefore, light from the backlight unit 1〇〇〇 may be input to the shirt color filter corresponding to the molecular arrangement of the liquid crystal. The backlight unit 1 is placed under the liquid crystal display panel and supplies light to the liquid crystal display panel. The liquid crystal display device using the optical film of the embodiment of the invention comprises a polarizer, a polarizing plate and a backlight unit, but the invention is not limited to the liquid crystal display device. The scope of the present invention covers a variety of display devices, including notebook computers, mobile phones, display screens for ice boxes, personal digital assistants, automated teller machines, and the like.
