之部分， 係形成於該底部基板11〇非設置有圖 亦即該阻光單元120不至於重疊蓋過 12 200912428 該等圖素電極191，然而，該阻光單元120之一端部可以部 分重疊涵蓋圖素電極191。該阻光單元120可以阻擋鄰近圖 素的光，避免混光。 具有多數固定槽孔315之固定阻障壁310係形成在該 5阻光單元120上’該固定阻障壁310可藉由一感光材料進 行塗佈、曝光並顯影等製程來形成。該固定阻障壁31〇可 利用不會透光之不透明材料來製成，當該固定阻障壁310 係由黑色材料所製成時可避免非預期的光通過該固定阻障 壁31〇或被該固定阻障壁310反射，因此可以避免減損顯 10示品質。如果該固定阻障壁310可以取代前述阻光單元120 之功能，則前述阻光單元120可以省略。每一個固定槽孔 315配置—個被驅動體370，每一圖素電極191係暴露於一 固定槽孔315中。 前述反光件350係形成於該固定阻障壁310上，該反 15光件350誘發散射光至該頂部基板210之一顯示區域。 具有該等驅動槽孔335之驅動阻障壁330係形成於該 反光件350上，每一驅動槽孔335之剖面係呈圓形，且該 面的寬度係以自該底部基板110朝向該頂部基板21 〇之 方向漸漸增加，亦即，該驅動槽孔335之形狀係呈一上下 20倒置的截頭圓錐形狀。該驅動槽孔335可設計成具有四邊 形之剖面，且在這狀況下，該驅動槽孔335將具有一上下 倒置之四方角錐形狀。該驅動阻障壁330可以用具有優良 穿透性的乾式光阻材料製成。 在每一個驅動槽孔335中係設置有一位置由電力強度 13 200912428 決之之球形被驅動體370，該被驅動體37〇具有正或負電 何，且可以具有多層結構；例如，該被驅動體37〇之外部 可以由有機薄膜製成，以便維持電荷，而該被驅動體37°〇 之内部可以由金屬層所製成，以便提供全反射效果。此外， 5該被驅動體370也可以由不透明材質製成，以便阻擔反射 光。 該被驅動體370之直徑d可以等於或大於該固定槽孔 315之寬度w，因此，該被驅動體37〇可以自由地在該驅動 槽孔335中運動，而不會落入該固定槽孔315中。如果該 1〇被驅動體370因該圖素電極191之吸引力而介於該反光^ 350與該固定槽孔315中以致於遮蔽住該固定槽孔315時， 從該背光模組400發出的光將會被擋住，基此，可以實現 完全黑色的顯示狀態。 μ 在此實施例中，因該被驅動體370無法完全地落入該 15固定槽孔315中，所以它無法與該圖素電極191接觸，= 因此，不需要在該圖素電極191上形成用以保護該圖素電 極191之絕緣層。 、屯 該驅動槽孔335填充有惰性氣體（圖中未顯示），例如 氬氣、氖氣及氦氣，伴隨著該被驅動體370。該惰性氣體可 20以被其他可以適當維持該被驅動體電荷之氣體（例如氮氣 或乾燥空氣）所取代。此外，該驅動槽孔335亦可被維持 在一真空狀態。 ' 該頂部基板210係與該驅動阻障壁330結合。 一用於紅、綠及藍色之彩色濾光片230被形成在該頂 14 200912428 部基板210上，且一絕緣層250係形成在該彩色濾光片23〇 上作為保護層。前述之共用電極270係形成在該絕緣層250 上’該共用電極270可以利用一透明導體，例如銦錫氧化 物(ITO)或銦鋅(IZO)氧化物製成。 5 前述絕緣層250與共用電極270係暴露於該驅動槽孔 335中，此外，该共用電極270係位於該驅動槽孔335之一 邊緣。詳s之’當該被驅動體370因該共用電極270之吸 引力作用而接觸該絕緣層250時，該共用電極270係位於 該被驅動體370與該絕緣層2520之接觸區域與該驅動阻障 ίο壁用以區隔出§亥驅動槽孔335之周緣之間，因此，用 以保護避免該被驅動體370與該共用電極270接觸之絕緣 層可以省略，因為該被驅動體370並不會直接接觸該共用 電極270。 供給光至該顯示面板1〇〇之背光模組4〇〇包含有一可 I5發光之燈具420、一用以將來自該燈具42〇所發出之直線光 源或點光源轉換成面光源之導光板41〇，以及一可以將來自 s亥導光板410之光聚焦至一顯示區域（亦即該固定槽孔315 及該驅動槽孔335)之聚光鏡。直線光源，例如冷陰極 螢光燈(CCFL)或外接電極妓燈(EEFL)，或者點光源，例 2〇如發光二極體(LED)，皆可作為該燈具42〇使用。當平面光 源作為該燈具420使用時，可以省略該導光板41〇。該聚焦 鏡430可以直接形成在該導光板41〇之表面中，或者可以 在該導光板410表面形成_單獨的層面。此外，該聚焦鏡 430可以單獨地製成-薄膜，或者在該顯示面板謂上形成 15 200912428 單獨的一層。 前述背光模組400可以設置在該底部基板11〇或該頂 部基板210上。 上述之電場驅動顯示裝置藉由電力或重力來移動位於 5該驅動槽孔335中之被驅動體370之位置，且透過該被驅 動體370之位移來控制發自該背光模組的光的穿透性，進 —步得到所需的影像。 上述電場驅動顯示裝置10之驅動方式，以下將藉由參 照第四圖來詳加說明。 10 一般而言，顯示裝置之顯示螢幕係以垂直一水平面之 姿態運作，因此被該驅動阻障壁330所區隔出之驅動槽孔 335的周緣，將形成一朝向該水平面傾斜之斜面；由於重力 衫·#，被驅動體370將滾到該斜面之低處。然而，當電 壓施加於該圖素電極191與該共用電極27〇之間時，電場 15將生成於一者之間’因此’藉由電力，帶電的被驅動體37〇 將克服重力而在該斜面上往上滾。施加於該被驅動體37〇 之電力’可藉由調整施加於該圖素電極191與該共用電極 270之間的電壓來控制’藉此可以控制該被驅動體谓之位 置為控制位置之目的’如第四圖所示，該驅動槽孔 2斜面：t具有固疋的斜率’或者該斜面的坡度可以漸漸 在上d此外’用以克服重力而施加於該被驅動體別 之電力強度將隨著前述斜面與水平面之爽角而改變，因此 驅動電Μ可按料同坡度情況㈣當地決定。 U亥驅制3孔335中可以讓來自背光模組_的光通過 16 200912428 的區域，將因該被驅動體370之位置改變而隨之改變，亦 即，當該被驅動體370接觸該斜面的底部，換言之，當該 被驅動體370接觸該頂部基板210時，該驅動槽孔335可 容許背光模組400的光通過的區域將達到最大值，且該區 5域將因該被驅動體370朝著該斜面往上滾動而漸漸減少， 而當該被驅動體370滾至該斜面之頂部並封住該固定槽孔 315時’前述的光將被完全地遮蔽。如前所述，藉由控制施 ( 加於該圖素電極191與該共用電極270之間的電壓，便可 以控制光通過量。 ίο 當來自背光模組400的光通過該驅動槽孔335，因該被 驅動體370之設置，可能造成部分的光散射，因而減損亮 度，此時，反光件350將誘發散射的光至頂部基板21()，藉 以避免亮度減損。 θ 藉由使用彩色濾光片230，可達成顯示彩色影像的目 15的。 I- 如本發明以上之陳述，光通過的量可以藉由控制該被 驅動體370在該驅動槽孔335中之位置而調整，然而，藉 由控制光遮蔽的時間亦可以控制光通過的量。 ㈢ .由於該被驅動體37〇之尺寸縣數至數十微米，因此 2〇該被驅動體370可以被數十毫伏特至幾伏特的電壓在非常 高速=驅動，因此本發明之顯示裝置可以提供高反應速度 以及精準控制。該被驅動體370之操作速度與其重量之間 具有比例關係，而藉由在該被驅動體3?〇中形成多數微孔， 可以減輕其重量。 17 200912428 在本發明上述之實施例中，係藉由重力及電力來驅動 該被驅動體370，然而，藉由施加一與既存之電力相反方向

blocking unit 120 is not partially disposed, that is, the light blocking unit 120 does not overlap the cover electrodes 191. However, one end of the light blocking unit 120 may partially overlap. Photon electrode 191. The light blocking unit 120 can block light from adjacent pixels to avoid mixing light. A fixed barrier 310 having a plurality of fixing slots 315 is formed on the 5 light blocking unit 120. The fixed barrier 310 can be formed by a coating, exposure, and development process of a photosensitive material. The fixed barrier 31 can be made of an opaque material that does not transmit light. When the fixed barrier 310 is made of a black material, unintended light can be prevented from passing through the fixed barrier 31 or being fixed. The barrier wall 310 reflects, so that the quality of the impairment can be avoided. If the fixed barrier layer 310 can replace the function of the foregoing light blocking unit 120, the foregoing light blocking unit 120 can be omitted. Each of the fixing slots 315 is configured as a driven body 370, and each of the pixel electrodes 191 is exposed to a fixing slot 315. The reflector 350 is formed on the fixed barrier wall 310, and the backlight 35 induces scattered light to a display area of the top substrate 210. A driving barrier 330 having the driving holes 335 is formed on the reflector 350. Each of the driving slots 335 has a circular cross section, and the width of the surface is from the bottom substrate 110 toward the top substrate. The direction of the 〇 is gradually increased, that is, the shape of the driving slot 335 is a frustoconical shape with an upper and lower 20 inversion. The drive slot 335 can be designed to have a quadrangular cross-section, and in this case, the drive slot 335 will have an inverted quadrangular pyramid shape. The drive barrier wall 330 can be made of a dry photoresist material having excellent penetration. Each of the driving slots 335 is provided with a spherical driven body 370 whose position is determined by the electric power intensity 13 200912428, which is positive or negative, and may have a multi-layer structure; for example, the driven body The outer portion of the 37 可以 can be made of an organic film to maintain the electric charge, and the inside of the driven body can be made of a metal layer to provide a total reflection effect. Further, the driven body 370 may be made of an opaque material to block the reflected light. The diameter d of the driven body 370 can be equal to or greater than the width w of the fixing slot 315. Therefore, the driven body 37 can freely move in the driving slot 335 without falling into the fixing slot. 315. If the one-way driven body 370 is interposed between the reflective surface 350 and the fixing slot 315 due to the attraction force of the pixel electrode 191 so as to shield the fixing slot 315, the backlight module 400 is emitted from the backlight module 400. The light will be blocked, and based on this, a completely black display state can be achieved. In this embodiment, since the driven body 370 cannot completely fall into the 15 fixing slot 315, it cannot be in contact with the pixel electrode 191, and therefore, it is not necessary to form on the pixel electrode 191. The insulating layer for protecting the pixel electrode 191. The drive slot 335 is filled with an inert gas (not shown) such as argon, helium and neon, accompanied by the driven body 370. The inert gas may be replaced by another gas (e.g., nitrogen or dry air) that can properly maintain the charge of the driven body. In addition, the drive slot 335 can also be maintained in a vacuum state. The top substrate 210 is bonded to the driving barrier wall 330. A color filter 230 for red, green, and blue is formed on the top substrate 12, 200912428, and an insulating layer 250 is formed on the color filter 23A as a protective layer. The aforementioned common electrode 270 is formed on the insulating layer 250. The common electrode 270 can be made of a transparent conductor such as indium tin oxide (ITO) or indium zinc (IZO) oxide. 5 The insulating layer 250 and the common electrode 270 are exposed in the driving slot 335. Further, the common electrode 270 is located at one edge of the driving slot 335. When the driven body 370 contacts the insulating layer 250 due to the attraction of the common electrode 270, the common electrode 270 is located at a contact area between the driven body 370 and the insulating layer 2520 and the driving resistance. The barrier wall is used to separate the periphery of the sigma drive slot 335. Therefore, the insulating layer for protecting the driven body 370 from contacting the common electrode 270 may be omitted because the driven body 370 is not The common electrode 270 is directly contacted. The backlight module 4 for supplying light to the display panel 1 includes a lamp 420 capable of emitting light, and a light guide plate 41 for converting a linear light source or a point light source emitted from the lamp 42 into a surface light source. And a concentrating mirror that can focus the light from the s-light guide plate 410 to a display area (ie, the fixed slot 315 and the drive slot 335). A linear light source, such as a cold cathode fluorescent lamp (CCFL) or an external electrode xenon lamp (EEFL), or a point source, such as a light emitting diode (LED), can be used as the lamp 42. When a planar light source is used as the lamp 420, the light guide plate 41A can be omitted. The focusing mirror 430 may be formed directly in the surface of the light guiding plate 41, or may form a separate layer on the surface of the light guiding plate 410. In addition, the focusing mirror 430 can be fabricated separately as a film or a separate layer of 15 200912428 can be formed on the display panel. The backlight module 400 may be disposed on the bottom substrate 11 or the top substrate 210. The above-mentioned electric field driving display device moves the position of the driven body 370 located in the driving slot 335 by electric power or gravity, and controls the light transmission from the backlight module through the displacement of the driven body 370. Transparency, step by step to get the desired image. The manner in which the above-described electric field drives the display device 10 will be described in detail below with reference to the fourth drawing. 10 In general, the display screen of the display device operates in a vertical horizontal plane, so that the periphery of the driving slot 335 separated by the driving barrier wall 330 will form a slope inclined toward the horizontal plane; The shirt ##, the driven body 370 will roll to the lower side of the slope. However, when a voltage is applied between the pixel electrode 191 and the common electrode 27A, the electric field 15 will be generated between one 'and thus' by the electric power, and the charged driven body 37 will overcome the gravity Roll up the slope. The electric power applied to the driven body 37 can be controlled by adjusting the voltage applied between the pixel electrode 191 and the common electrode 270. Thus, the position of the driven body can be controlled to control the position. 'As shown in the fourth figure, the drive slot 2 bevel: t has a solid slope' or the slope of the slope may gradually be on the upper d' to overcome the gravity applied to the driven body's power intensity As the aforementioned slope and the refreshing angle of the horizontal plane change, the driving power can be determined locally according to the same slope condition (4). The U-driving 3 hole 335 allows the light from the backlight module _ to pass through the area of 16 200912428, which will change due to the change of the position of the driven body 370, that is, when the driven body 370 contacts the inclined surface The bottom portion, in other words, when the driven body 370 contacts the top substrate 210, the driving slot 335 can allow the area through which the light of the backlight module 400 passes to reach a maximum value, and the area 5 field will be the driven body The 370 rolls upwardly toward the slope and gradually decreases, and when the driven body 370 rolls to the top of the slope and seals the fixing slot 315, the aforementioned light will be completely shielded. As described above, the light throughput can be controlled by controlling the voltage applied between the pixel electrode 191 and the common electrode 270. ίο When light from the backlight module 400 passes through the driving slot 335, Due to the arrangement of the driven body 370, part of the light may be scattered, thereby reducing the brightness. At this time, the reflector 350 will induce the scattered light to the top substrate 21 () to avoid luminance loss. θ by using color filter The sheet 230 can achieve the objective of displaying a color image. I- As stated in the above description of the invention, the amount of light passing can be adjusted by controlling the position of the driven body 370 in the driving slot 335, however, The amount of light passing can also be controlled by the time of the control light. (3) Since the size of the driven body 37 is tens of micrometers, the driven body 370 can be tens of millivolts to several volts. The voltage is driven at a very high speed = so that the display device of the present invention can provide high reaction speed and precise control. The operating speed of the driven body 370 is proportional to its weight, and by the driven body 3? In the above embodiment of the present invention, the driven body 370 is driven by gravity and electric power, however, by applying a direction opposite to the existing power. The power can be replaced or assisted by the gravity, that is, the driven body 370 can be recovered by reversing the voltage direction applied between the pixel electrodes 191 and 5, the common electrode 270, without gravity. Referring to the fifth figure, an electric field driven display device according to another embodiment of the present invention will be described. Fig. 5 is a cross-sectional view showing an electric field driven display device according to another embodiment of the present invention, wherein The same or similar elements will be given the same reference numerals. The electric field driven display device 20 according to an embodiment of the present invention includes a display panel 100. The display panel 100 includes a bottom substrate 110 on which a plurality of pixel electrodes 191 and a plurality of switches 130 are disposed, and a common electrode 15 270 is disposed thereon. The top substrate 210, a fixed barrier wall 310 having a plurality of fixing slots 315, a driving barrier wall 330 having a plurality of driving slots 335, and a reflector 350 disposed between the fixed barrier wall 310 and the driving barrier wall 330 And a driven body 370 disposed in each of the driving slots 335. The driven body 370 may have a positive or negative charge and may be reflective, and the driving body 370 may be white, red, green, blue, One of colors such as yellow, magenta, and cyan, by using these colors, color image display can be achieved. Unlike the electric field driven display devices shown in the first to fourth figures, the electric field driven display of this embodiment The device 20 does not include the color filters 230, 18 200912428 ! the edge layer 250 or the light module 4 , and the image can be displayed by an external light source. Further, the pixel electrode 191 T is made of indium tin oxide, indium zinc oxide, conductive polymer or metal. The drive mode 5 of the electric field drive display device 20 shown in Fig. 5 will be described below. As shown in the fifth figure, by the voltage applied between the pixel electrode 191 and the common f electrode 270, the driven body '390 located at the first driving slot 335 & is located at the top of the 5th inclined surface. By the other voltage applied between the pixel electrode 191 and the common electrode 270, the driven body 390 located in the second driving slot 10 335b is located at a middle position of the inclined surface, and further, by applying to the figure A further voltage between the element electrode 191 and the common electrode 270 or by the gravity 'the driven body 390 located in the third driving slot 335c is located at the bottom of the inclined surface', the amount of reflected light or incident light will follow The position of the driven body 390 changes and changes. The driven body 390 located in the third driving slot 3 3 5 c 15 is closest to the top substrate 210, so incident light from the external cymbal can be completely reflected by the driven body 390; in the second driving slot The driven body 390 in 335b is spaced apart from the top substrate 21 by a predetermined distance, so that the incident light system portion from the outside is reflected, thereby exhibiting a medium gray scale; and being located in the first driving slot 335a Since the driving body 390 2 is farthest from the top substrate 210, it is difficult to reflect incident light from the outside; in this way, by controlling the position of the driven body 390 in the driving slot 335, image display is achieved. Hereinafter, a method of manufacturing the electric field driven display device * provided by the present invention - the embodiment will be described with reference to the sixth fifteenth diagram. 19 200912428 A sixth to fifteenth diagram gradually shows the manufacturing method of the electric field driven display device shown in the first and second figures. First, as shown in the sixth figure, the pixel electrode 191 and the switch 13 are formed on a bottom substrate 11A made of a transparent material such as glass or plastic. The switch 130 may be a thin film transistor. Under these conditions, a gate line and a data line having a source, a drain, and a semiconductor are also formed on the base substrate 110 at the same time. 7 ' μ As shown in the seventh figure, a light blocking material layer 121 is formed on the base substrate 110, the pixel electrode 191, and the switch 130. Subsequently, as shown in the eighth figure, 'a photosensitive material layer 311' is formed by coating a photosensitive material on the light-receiving material layer 121. As a method of coating the photosensitive material, a spin coating method may be used, and the photosensitive method may be used. The material contains a negative photoresist. The photosensitive material layer 311 is then subjected to an exposure and development process. Using the developed photosensitive material layer 311 as a residual mask, etching the exposed light blocking material 2 results, as shown in the ninth figure, forming a fixed barrier wall 31G having a fixed t hole 315 and the light blocking single illusion 2〇. The light blocking unit 12 is located between the bottom substrate 110 and the surface of the fixed barrier, and only a very small portion is exposed in the (4) slot 315. The light unit 12A can be made of a photosensitive material. In this case, a first photosensitive film of the material is formed on the bottom substrate and the switch 130, and the photosensitive material layer is on the photosensitive film. Subsequently, an exposure and development process is simultaneously performed on the first-photosensitive film layer 311 to complete the light-blocking early 120 and the fixed barrier layer 310. 20 20 200912428 Next, as shown in the tenth figure, a reflector member is formed on the fixed barrier wall 310, and the reflector (10) is in contact with the fixed barrier wall 3ig.
