Description of the invention: [Technical field to which the invention pertains] The present invention relates to a display device. In particular, it refers to a display device driven by an electric field. 5 [Prior Art] The types of displays widely used today include a liquid crystal display, a piasma display panel, and an organic electro luminescence display. The liquid crystal display is a liquid crystal display. A display device that displays (1) an image of electro-optical properties. In a liquid crystal display, the transmittance of light will vary with the applied electric field' and its viewing angle is narrower and the cost is higher. A plasma display uses a plasma generated by a gas discharge to display an image. Since the discharge gas is at a high temperature, the plasma display panel generates a considerable amount of heat. An organic electroluminescent display injects electrons and holes from a cathode (electron injection electrode) and an anode I5 (hole injection electrode) into an organic light-emitting layer and causes it to collapse from an excited state to a ground state. A display device that emits light excitons (exit〇n). In this display device, only part of the injected charge is used, and the rest is consumed in the form of heat. In addition, widely used display devices include a flad emission display and an electrophoretic display (electr〇ph〇retic display). The field emission display uses quantum mechanical tunneling to cause electrons emitted from electron emitters located at the cathode to strike a fluorescent object located at the anode to excite the fluorescent object to emit light, thereby realizing a specific image; electrophoretic display by electrophoresis Allow the pattern or text to be displayed or removed repeatedly. 6 200933233 SUMMARY OF THE INVENTION An object of the present invention is to provide a novel display device which is different from the conventional display device and which is driven by an electric field.

構與具有感光性。該第一絕緣臈150可以諸如氮化矽或氧 化矽之類的有機膜製成，亦可以為具有有機膜與無機膜之 二元膜結構。 1〇 一接觸電極170係形成於該第一絕緣膜150上。該接 觸電極170包含有一具有第一開口 175p之第一金屬層 i70p，以及一具有第二開口 175q之第二金屬層I70qe此 外，該接觸電極170係由不透明材料製成，藉以阻隔光線。 該第一開口 175p與該第二開口 175q之截面係成圓形，然 〇 15而，該第一開口 175P與該第二開口 175q之截面形狀可以 依據該被驅動體370之形狀而有所不同。而且，該接觸電 極170可以由二層或多層金屬層構成。 該第一金屬層170p係直接形成於該第一絕緣膜15〇 上，且該第一金屬層17〇p之第一開口 175p係與該第一孔 20 1 55連通。該第一金屬層Π〇ρ可以諸如鋁(A1)或鉬(Mo)之 類的金屬製成。 該第二金屬層170q係直接形成於該第一金屬層i7〇p 上，此外，該第二金屬層170q之第二開口 i75q係與該第 一開口 175p連通。然而，該第二開口 p5q之直徑係小於 11 200933233 該第一開口 175p之直徑。該第二金屬層170q可以諸如錄 之類的金屬製成。 該接觸電極170係連接於獨立的佈線(圖未示），並從其 接受一電壓。接收一電壓之該接觸電極170施加該電壓於 5 該被驅動體370。施加於該接觸電極170之電壓大小可與施 加於該圖素電極120之電壓大小相同或接近，而且，施加 於該接觸電極170之電壓極性大小可與施加於該圖素電極 120之電壓極性相同或相反。該電壓之大小可以隨著該顯示 裝置10之設計不同而變化，且該電壓之極性可以根據該被 10 驅動體370之移動方向而做選擇。 此外，該接觸電極170可以直接連接該圖素電極120 或該共用電極270 ’而從該圖素電極120或該共用電極270 接收電壓。 15 ❹ 具有上述結構之接觸電極170可遮蔽通過該底部基板 110之光線，因此該接觸電極170扮演著阻障構件之角色。 此外，該接觸電極170可以施加該被驅動體370 —電壓， 以恆保該被驅動體370之靜電特性’藉以精確地控制該被 驅動體370之位置。 在本實施例中’該接觸電極170係由該第一及第二金 2〇屬層170p及170q此雙層結構所形成。惟，如第二圖所示， 接觸電極170係可由單層結構所形成。此外，在該底部電 極110與該第一絕緣膜15〇之間，可以形成一遮蔽件14〇， 且該遮蔽件140之形成並未與該圖素電極12〇交疊。該遮 蔽件140可以避免鄰近圖素之混光，在第二圖中，因為存 12 200933233 在有該遮蔽件140’因此該接觸電極17〇可以由諸如銦鍚氧

-定義出多數驅動區域335之隔牆33〇,係形 二絕緣膜18〇上。每-驅動區域335係與該第二絕緣膜'8〇 之第二孔I85連接。該隔牆33〇可利用感光材料藉由塗佈、 曝光及顯影而製成。該隔牆33〇可以為光線無法穿透之不 透明材料所製成，例如，該隔牆33〇可以由黑色材料所形 ^ ’以避免不必要的光穿過該隔牆33〇或因該隔牆反射光 線而造成顯不品質減損。該驅動區域335之截面係為圓形， ^驅動區域之截面面積可以自該底部基板m往該頂部 基板210之方向遞減，亦即，該驅動區域335具 ===動區域之截面面積亦可以自該底部基板ιι〇 ，該頂雜板21G之方向遞增，在此情況時，該驅動區域 335之形狀係呈上下倒置之截頭圓錐形狀。 區域335與該第二幻以，係設置有一位 定之球形被驅動體370，且該被驅動體37〇 开:ώ二二。該被驅動體37°可以以多層結構之方式 形成，例如，該被驅動體37G之外部可以由有_膜製成， 20 200933233 以便維持電荷，而其内部可以由金屬層所製成，以便提供 全反射效果。此外，為了排除反射光線，該被驅動體 也可以由不透明材質製成。 該被驅動體370之直徑係等於或大於該第二開口 175q 5之直徑’因此’該被驅動體37〇可以自由地在該驅動區域 335與該第二孔185之空間中運動，而不會落入該第二金屬 ❹ 層170(1之低處。如果該被驅動體370因該圖素電極120與 該接觸電極170之吸引力而遮蔽住該第二開口 175q時，從 該背光模組400發出的光將會被擋住，基此，可以實現全 10黑狀態。由於該被驅動體370之位置係由該圖素電極12〇、 該共用電極270以及該接觸電極170所控制，因此該被驅 動體370之位置可以精準地控制。 該驅動區域335中填充有惰性氣體，例如氬氣、氖氣 及氦氣等等’伴隨著該被驅動體370。該惰性氣體可以被其 β丨5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，該驅動區域335亦可被維持在一真 空狀態。 該頂部基板210係與該隔牆330結合。 用以實現彩色影像之紅、綠及藍色彩色濾光片230被 .20形成在該頂部基板210上，且用以保護之第三絕緣膜250 係形成在該彩色濾光片230上。此外’共用電極270係形

層面中形成’或者以單獨薄膜之型態形成，或者在該顯示 面板100之一側上形成單獨的一層。 前述背光馳4GG可以設置在該底部基板11G或該頂 15部基板210上。 此電場驅動顯示裝置藉由施加電力於位在該驅動區域 335中之被驅動體370來移動其位置，且藉由控制發自該背 光模組400光量，顯示所需的影像。 以下將參照第二圖來描述具有上述結構之電場驅動顯 2〇示裝置10的驅動方式。 在根據本實施例之顯示裝置令，該驅動區域335允許 發自背光模IE _的光線通過的面積，取決於該被媒動艘 370之位置，亦即，當該被驅動體37〇接觸該共用電極27〇 時’該驅動區域335能允許光線通過的面積達為最大；當 15 200933233 該被驅動體370沿著傾斜側往下滾時，可允許光線通過的 面積將減少；而當該被驅動體37〇遮蔽住該第二開口 175q 時’光線將被完全擋住。如前述，光線朝向該頂部基板21〇 之大小，係依據位於該驅動區域335中之被驅動體37〇的 5 位置而被控制。 藉由控制該接觸電極170、該圖素電極12〇與該共用電 ❹ 極270的尺寸及極性，可以控制該被驅動體370的位置。 例如，如果施加於該接觸電極17〇與該圖素電極12〇的電 壓極性係相同，而施加於該共用電極27〇的電壓極性與施 H)加於該接觸電極170與該圖素電極12〇的電壓極性係相 反，該被驅動體370可以往該共用電極27〇之方向移動。 反之，如果施加於該接觸電極17〇與該圖素電極12〇的電 壓極性係不同，而施加於該共用電極27〇的電壓極性與施 加於該接觸電極170的電壓極性係相同，該被驅動體別 〇 15可以往該接觸電極m之方向移動。施加於該接觸電極 170、該圖素電極120與該共用電極27〇的電壓強度

漸漸增加。此外’按著該周緣表面相對該水平面的夾角大 小，施加於該被驅動體之地心引力大小將有所不同，在不 同的狀況下’施加於該共用電極27〇、該圖素電極12〇與該 接觸電極170之電壓可以適當地調整。 藉由控制該被驅動體370在該驅動區域335中之位置 而控制光線通過量之方法，在此已經清楚描述，此外，藉 由控制該被驅動體370遮蔽光線的時間，亦可控制光線之 通過量。 & 17 20 200933233 由於該被驅動體370之尺寸僅為數至數十微米 (micrometer)，因此該被驅動體370可以被數十毫伏特(mV) 至幾伏特(V)的電壓驅動’而且因其可以在非常高速下被驅 動’因此可以提供一種反應速度極高且可精準控制之顯示 5裝置。因為該被驅動體370之操作速度與其重量成反比， 因此，可以在該被驅動體370中形成凹孔，以減輕其重量。 在第三圖所示的結構中，因為該共用電極270、該圖素 電極120以及該接觸電極170形成該電場，因此可以更為 精準地控制該被驅動體370的位置。 10 除此之外，電場驅動顯示裝置可以不包含該背光模組 400，亦即，與第一圖所示之電場驅動顯示裝置不同，而係 藉由外部光源來顯示影像。此種電場驅動顯示裴置係藉由 控制該被驅動體反射該外部光源的大小來體現影像，如果 該被驅動體靠近頂部電極，自外部來的入射光將完全被該 I5被驅動體反射，而如果該被驅動體係離開該頂部電極一定 距離，因為僅有部分來自外部的入射光被該被驅動體反 射’因此將呈現中度灰階，此外，在該被驅動體離開該頂 部電極至一最遠距離時，來自外部的入射光幾乎無反射現 象。根據前述方式，藉由控制該被驅動體位於該驅動區域 20的位置’可以顯示影像，而在此等狀況下’該被驅動體苛 以為白色、紅色、綠色、藍色、黃色、紫紅色和藍綠色等 顏色所構成之群組中所選出的任一顏色，藉此實現各種彩 色影像。 接下來將藉由第四a圖至第四e圖，詳細說明根據本 200933233 發明一實施例所為之電場驅動顯示裝置的製造方法。 第四a圖至第四e圖係為一系列介紹如第一圖所示之 電場驅動顯示裝置10之製造流程圖。 首先，如第四a圖所示，圖素電極120及開關130係

[Embodiment] In the drawings, the thickness of layers, etc. are exaggerated for the sake of clarity. In addition, the plate phase in the entire specification = the cows are indicated by the phase _ reference number. Where an element, such as a layer, film, region, or substrate, is provided "on" another element 9 200933233, it means that the element can be directly disposed on the other element, or other intermediate elements can be present therebetween. . In contrast, when an element is referred to as being "directly on" another element, it means that there is no intervening element in between. 5 Referring to the first figure, an electric field driven display device according to an embodiment of the present invention will be described below. BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is a cross-sectional view of an electric field driven display device according to an embodiment of the present invention. As shown in the first figure, an electric field driven display device 10 includes a display 10 panel 100 and a backlight module 400. The display panel 100 is a member for displaying an image thereon by controlling the size of the light, and the display panel 100 includes a bottom substrate 11 on which the pixel electrode 120 is formed, and a common electrode 27 is formed thereon. The top substrate 210, a partition wall 330 formed with a driving region 335, and a driven body 370 disposed at the driving region 335 of I5. The pixel electrodes 120' extending in one direction are disposed in parallel with each other on the base substrate 11 made of glass or the like. The pixel electrode 12 can be made of a transparent conductive material such as indium lanthanum oxide (yttrium oxide) or indium zinc oxide (yttrium). Further, a switch 130' for individually switching the voltage applied to each of the pixel electrodes 12A is formed on the base substrate 110 and electrically connected to the pixel electrode 120. A thin film transistor can be used as the switch 130, and when a thin film transistor is used as the switch 130, a gate line (not shown) for transmitting a signal to turn on/off the thin film transistor, and for transmission to be applied to the figure 200933233 A data line (not shown) of the gray scale voltage of the element electrode 120 may be formed on the base substrate 110 while being overlapped with each other. The thin film transistor may include a gate, a source, a drain, and a semiconductor. A first insulating film 150 is formed on the bottom substrate 11 and the switch 5 I30 and the first insulating film 150 is formed with a first hole 155 for exposing the pixel electrode 120. The first insulating film 15A may have a single organic film structure and be photosensitive. The first insulating layer 150 may be made of an organic film such as tantalum nitride or hafnium oxide, or may be a binary film structure having an organic film and an inorganic film. A contact electrode 170 is formed on the first insulating film 150. The contact electrode 170 includes a first metal layer i70p having a first opening 175p and a second metal layer I70qe having a second opening 175q. The contact electrode 170 is made of an opaque material to block light. The cross section of the first opening 175p and the second opening 175q is circular, and the cross-sectional shape of the first opening 175P and the second opening 175q may be different according to the shape of the driven body 370. . Moreover, the contact electrode 170 may be composed of two or more metal layers. The first metal layer 170p is directly formed on the first insulating film 15b, and the first opening 175p of the first metal layer 17p is in communication with the first hole 20 1 55. The first metal layer Π〇ρ may be made of a metal such as aluminum (A1) or molybdenum (Mo). The second metal layer 170q is formed directly on the first metal layer i7〇p, and the second opening i75q of the second metal layer 170q is in communication with the first opening 175p. However, the diameter of the second opening p5q is smaller than the diameter of the first opening 175p of 11 200933233. The second metal layer 170q can be made of a metal such as a recording. The contact electrode 170 is connected to a separate wiring (not shown) and receives a voltage therefrom. The contact electrode 170 receiving a voltage applies the voltage to the driven body 370. The magnitude of the voltage applied to the contact electrode 170 may be the same as or close to the voltage applied to the pixel electrode 120, and the polarity of the voltage applied to the contact electrode 170 may be the same as the polarity of the voltage applied to the pixel electrode 120. Or the opposite. The magnitude of the voltage may vary depending on the design of the display device 10, and the polarity of the voltage may be selected based on the direction of movement of the driven body 370. In addition, the contact electrode 170 may directly connect the pixel electrode 120 or the common electrode 270' to receive a voltage from the pixel electrode 120 or the common electrode 270. 15 接触 The contact electrode 170 having the above structure shields light passing through the base substrate 110, and thus the contact electrode 170 functions as a barrier member. Further, the contact electrode 170 can apply the voltage of the driven body 370 to constantly maintain the electrostatic characteristics of the driven body 370 by precisely controlling the position of the driven body 370. In the present embodiment, the contact electrode 170 is formed by the two-layer structure of the first and second metal layers 170p and 170q. However, as shown in the second figure, the contact electrode 170 may be formed of a single layer structure. In addition, a shielding member 14A can be formed between the bottom electrode 110 and the first insulating film 15A, and the shielding member 140 is not formed to overlap the pixel electrode 12A. The shielding member 140 can avoid the light mixing of the neighboring pixels. In the second figure, since the covering member 12200933233 has the shielding member 140', the contact electrode 17 can be oxidized by, for example, indium antimony oxide (antimony) or antimony zinc. Made of transparent material such as ΙΖΟ. A second insulating film 180 is formed on the second metal layer 17'. The second insulating film 180 has a portion connecting the second opening 175q and exposing a portion of the second metal layer 170q adjacent to the second opening σ qq = Ο 10 15 ❹ 185. The second insulating film 18G may have a single-organic riding structure and a photosensitive property. The second -18G may be made of an organic film such as a nitrogen cut or an oxygen cut, or may be a binary film structure having an organic film and no. - A partition wall 33 of a plurality of driving regions 335 is defined, and the two insulating films 18 are formed. Each of the driving regions 335 is connected to the second hole I85 of the second insulating film '8'. The partition wall 33 can be formed by coating, exposing, and developing a photosensitive material. The partition wall 33 can be made of an opaque material that cannot penetrate light. For example, the partition wall 33 can be formed of a black material to avoid unnecessary light passing through the partition wall 33 or because of the partition. The wall reflects light and causes no deterioration in quality. The cross-sectional area of the driving region 335 is circular, and the cross-sectional area of the driving region can be decreased from the bottom substrate m toward the top substrate 210, that is, the driving region 335 has a cross-sectional area of the === moving region. From the bottom substrate ιι, the direction of the top board 21G is increased, in which case the shape of the driving area 335 is frustoconical in an upside down shape. The region 335 and the second illusion are provided with a predetermined spherical driven body 370, and the driven body 37 is opened: ώ22. The driven body 37° may be formed in a multilayer structure. For example, the external portion of the driven body 37G may be made of a film, 20 200933233 to maintain electric charge, and the inside thereof may be made of a metal layer to provide Total reflection effect. Further, in order to exclude reflected light, the driven body may also be made of an opaque material. The diameter of the driven body 370 is equal to or larger than the diameter of the second opening 175q 5 'so that the driven body 37 〇 can freely move in the space of the driving area 335 and the second hole 185 without Falling into the lower portion of the second metal ruthenium layer 170 (1). If the driven body 370 shields the second opening 175q due to the attraction of the pixel electrode 120 and the contact electrode 170, the backlight module is removed from the backlight module. The light emitted by the 400 will be blocked, and accordingly, a full black state can be achieved. Since the position of the driven body 370 is controlled by the pixel electrode 12, the common electrode 270, and the contact electrode 170, The position of the driven body 370 can be precisely controlled. The driving region 335 is filled with an inert gas such as argon gas, helium gas, neon gas or the like 'accompanied by the driven body 370. The inert gas can be β 丨 5 He can properly replace the gas of the driven body charge (such as nitrogen or dry air). In addition, the driving region 335 can also be maintained in a vacuum state. The top substrate 210 is coupled to the partition wall 330. Color realization The red, green, and blue color filters 230 are formed on the top substrate 210, and a third insulating film 250 for protection is formed on the color filter 230. Further, the common electrode 270 A fourth insulating film 280 is formed on the third insulating film 250, and a fourth insulating film 280 is formed on the common electrode 270. The third insulating film 250 and the fourth insulating film 280 may be made of an organic film or the like. The common electrode 270 200933233 can be made of a transparent conductor, such as indium tin oxide (IT〇) or indium zinc (IZ〇) oxide. The backlight module 400 is a supply light to the display panel 1 The component of the crucible comprises a lamp 420, a light guide plate 41 for converting a linear light source or a point light source emitted from the lamp 42 to a surface light source, and a light from the light guide plate 410. Focusing on a concentrating mirror 430 of a driving region 335 of a display zone. A linear light source such as a cold cathode fluorescent lamp (CCFL) or an external electrode fluorescent lamp (EEFL), or a point source such as a light emitting diode (LED) can be used. Used as the luminaire 420. When flat light When the lamp 1 420 is used, the light guide plate 41 can be omitted. Alternatively, it can be formed directly on the surface of the light guide plate, or formed in a separate layer or formed in a separate film type. Or forming a separate layer on one side of the display panel 100. The backlight 3GG may be disposed on the bottom substrate 11G or the top 15 substrate 210. The electric field driving display device is placed in the driving region by applying electric power. The driven body 370 in 335 moves its position, and by controlling the amount of light sent from the backlight module 400, the desired image is displayed. The driving manner of the electric field drive display device 10 having the above structure will be described below with reference to the second drawing. In the display device according to the present embodiment, the area in which the driving region 335 allows the light emitted from the backlight mode IE_ to pass depends on the position of the medium loaded ship 370, that is, when the driven body 37 contacts the When the common electrode 27 is ', the area of the driving region 335 can allow the light to pass to the maximum; when the driven body 370 is rolled down along the inclined side at 15 200933233, the area through which the light can be allowed to pass is reduced; When the driving body 37 〇 shields the second opening 175q, the light will be completely blocked. As described above, the size of the light toward the top substrate 21 is controlled in accordance with the position of the driven body 37A located in the drive region 335. The position of the driven body 370 can be controlled by controlling the size and polarity of the contact electrode 170, the pixel electrode 12A, and the common electrode 270. For example, if the polarity of the voltage applied to the contact electrode 17 〇 and the pixel electrode 12 系 is the same, the polarity of the voltage applied to the common electrode 27 与 is applied to the contact electrode 170 and the pixel electrode 12 . The voltage polarity of the crucible is reversed, and the driven body 370 can move in the direction of the common electrode 27〇. On the other hand, if the polarity of the voltage applied to the contact electrode 17 and the pixel electrode 12 is different, and the polarity of the voltage applied to the common electrode 27 is the same as the polarity of the voltage applied to the contact electrode 170, the driven The body pin 15 can be moved in the direction of the contact electrode m. It is applied to the contact electrode 170, the voltage of the pixel electrode 120 and the common electrode 27A in the range of 0.5 V to 5 V' and can be changed in accordance with the size of displaying $1 以及 and the purpose of the calculation. The voltage intensity applied to the contact electrode 17A, the pixel electrode and the common electrode 270 is not limited to the aforementioned value. Further, the driven body can be driven by the contact electrode 170, the supplied electric power of the pixel power 120 and the common electrode 270, and gravity. In general, when the display device is in use, the displayed image is almost perpendicular to a horizontal plane, so that the partition 3 forming the driving region 335 will form an inclined surface with respect to the horizontal plane; due to the influence of gravity, The driven body 37G on the surface of the oblique 200933233 will roll down along the slope. In the present embodiment, the side of the '::: is different from the inclination direction of the peripheral surface of the partition wall 330, and the second hole (8) of 0 moves the driven body 37 by gravity, so that the peripheral surface of the wall 330 is used. The direction of inclination is the same = direction:: ❹ 10 ❹ 15 27. The pixel electrode 120 and the contact electrode 17 are added: ί gravity is applied to the 'and the charged driven body 370 will receive the electrified soil to overcome gravity and go upward toward the common electrode 27〇 As described above, 'when the body of the body is 37, the electrode (7) is lifted by gravity, and when the driven body 370 is displaced in the direction of the common electrode=, the contact electrode 17 is used. 〇, the figure and the electric field strength derived by the common electrode 270. As shown in the third figure, the peripheral surface 1 of the partition wall forming the driving region 335 has a specific slope, or the slope of the peripheral surface of the partition wall can be gradually increased. In addition, according to the angle between the peripheral surface and the horizontal plane, the gravity of the gravity applied to the driven body will be different, and applied to the common electrode 27〇, the pixel electrode 12〇 under different conditions. The voltage with the contact electrode 170 can be appropriately adjusted. The method of controlling the amount of light passing by controlling the position of the driven body 370 in the driving region 335 is clearly described herein. Further, by controlling the time during which the driven body 370 blocks light, the light can be controlled. Through quantity. & 17 20 200933233 Since the size of the driven body 370 is only a few to several tens of micrometers, the driven body 370 can be driven by voltages of several tens of millivolts (mV) to several volts (V). It can be driven at very high speeds' thus providing a display 5 device with extremely high response speed and precise control. Since the operating speed of the driven body 370 is inversely proportional to its weight, a recessed hole can be formed in the driven body 370 to reduce its weight. In the structure shown in the third figure, since the common electrode 270, the pixel electrode 120, and the contact electrode 170 form the electric field, the position of the driven body 370 can be controlled more accurately. In addition, the electric field driven display device may not include the backlight module 400, that is, unlike the electric field driven display device shown in the first figure, the image is displayed by an external light source. The electric field driving display device reflects the image by controlling the size of the external light source reflected by the driven body. If the driven body is close to the top electrode, the incident light from the outside will be completely reflected by the I5 driven body. And if the driven system leaves the top electrode a certain distance, because only part of the incident light from the outside is reflected by the driven body', it will exhibit a medium gray scale, and further, the driven body leaves the top electrode to a At the longest distance, incident light from the outside is almost non-reflective. According to the foregoing manner, an image can be displayed by controlling the position of the driven body at the driving area 20, and in this case, the driven body is white, red, green, blue, yellow, magenta, and Any color selected from the group consisting of cyan and other colors, thereby realizing various color images. Next, a method of manufacturing the electric field driven display device according to an embodiment of the invention of the present invention will be described in detail by the fourth to fourth e-drawings. The fourth through fourth e-pictures are a series of manufacturing flow diagrams for introducing the electric field driven display device 10 as shown in the first figure. First, as shown in Fig. 4a, the pixel electrode 120 and the switch 130 are formed on the base substrate 110 made of a transparent insulating material such as glass or plastic. The switch 13A may be a thin film transistor. Under these conditions, a gate line, a data line having a source, a drain, and a semiconductor are formed on the base substrate 110. Next, as shown in FIG. 4B, the layered structures of the first insulating film 150, the first metal layer ίο 170p, the second metal layer i7〇q, and the second insulating film 18〇 are sequentially stacked on the base substrate. 11〇, the pixel electrode 12〇 and the switch 130 have an organic film in which the first and second insulating films 15〇 and 18 are monolayers. Furthermore, as shown in FIG. 4C, the first hole 185, the second opening 175q, the first opening 175p, and the first hole 155' are formed by etching the above-mentioned layered structure, thereby exposing the pixel electrode. 120. Next, as shown in FIG. 4D, 'the partition wall 330 defining the driving region 335 is formed, and the driven body 370 is placed in the driving region 335 'where' the driven body 370 is set by the nanoprobe Into the drive area. 20, as shown in FIG. 4E, the color filter 230, the third insulating film 250, and the top substrate 21 on which the common electrode 270 is formed are bonded to each other to manufacture the display panel 100, and then the backlight module is assembled. 400 is coupled to the base substrate 110 to complete the electric field driving display device 10. As described above, according to an embodiment of the present invention, gravity and power 200933233 can be used to control the position of the driven body', thereby controlling the light to display a desired image.四 (4) Secondly, according to the actual compensation of the present invention, due to the arrangement of the contact electrodes, the electrostatic impurities of the _ body are maintained by the constant f, so that the position of the driven body can be controlled freshly. Therefore, the amount of light passing through the display panel can be controlled more accurately to achieve high quality images.虽然 10 Although the technical content of the present invention has been described by the presently applicable embodiments, it is to be understood that the present invention is not limited to the foregoing disclosed embodiments, but instead belongs to the following claims.
