有鑑於斯，本發明之目的在於提供一種可撓配線板反 折部並未突出於顯示面板外側，且顯示模組組裝容易， 同時可將所安裝電子機器予以適當小型化的顯示模 組。 緣是，本發明所提供之顯示模組，爲達上述目的，乃具 備有一對基板、端子配線部、電光學顯示面板、可撓 配線板；而該一對基板係在相互對向的基板內面分別形 成電極者；該端子配接部係由配置於該等一對基板間的 電光學物質所構成，並在位於該一對基板內之顯示觀察 側的前基板上，使前基板之一端緣，較與該前基板相對 向之後基板的相對應端緣更加突出者；該電光學顯示面 板係配接於該端子配接部內面上，並形成電性連接於該 電極之端子電極者；該可撓配線板係形成配線的一端， 電性連接於該配線、與該電光學顯示面板的端子電極 上，並固接於該端子配接部內面，而另一端則在較該 端子配接部最外緣更靠內側的區域中反折彎曲，而配置 於電光學顯示面板後面者。 此顯示模組，因爲使可撓配線板在較該端子配接部最 外緣更靠內側的區域中反折，所以可撓配線板的反折部 並無突出顯示面板外側的現象發生。故，在組裝於電子 6- 1287159 五、發明説明（5 ) 機器上較爲容易，且所安裝之電子機器亦可達小型化之 功效。 本發明所提供之顯示模組中，可撓配線板之一端供連 接的區域，最好設定爲較顯示面板之端子配接部最外端 緣，僅內縮特定距離的區域。此情況下，可撓配線板最 好在較端子配接部最外端緣更內側的區域中反折。如 此，藉由此反折，可撓配線板便不易由端子配接部剝 離。 所以，當將可撓配線板反折時，最好在其反折部分的 內面上，設置供限制該反折部分形狀的反折引導構件。 藉此便可更加確實使可撓配線板的反折部分不致突出 於該顯示面板外側，同時亦可將可撓配線板的反折形狀 設爲一定，使由顯示面板與可撓配線板所組成的整體顯 示模組形狀，在量產多數量顯示模組時，可達相同形狀 規格化的功效。 再者，本發明可適用於使用電光學物質爲液晶之液晶 顯示模組中，其中更以使用於強烈要求小型化之反射型 液晶顯示模組上爲佳。所以，當使用於反射型液晶顯示 模組時，係藉由將光反射板配置於後基板內面，或將設 置於後基板內面上之電極兼作爲反射板而構成，除可更 進一步促進液晶顯示模組的小型化之外，尙可達提昇反 射顯示畫質之功效。 [實施例] 以下，請參閱所附圖式，針對本發明實施例進行詳細 1287159 五、發明説明（6 ) 說明。 第2圖所示係本發明第丨實施例之顯示模組的部分 剖面示意圖。此實施例之顯示模組，係採用反射型液晶 顯示面板20作爲電光學顯示面板者，乃具備有該液晶 顯示面板20,與一端連接於該液晶顯示面板2〇之端子 配接部2 1 a內面，並在其黏接部附近反折而配置於該液 晶顯示面板2 0後面上的可撓配線板3 1。該反射型液 晶顯示面板20係譬如屬單純矩陣方式者，在相對向配 置並挾置液晶層27的前後一對基板2 1，2 2，於其中之 一基板（譬如成爲觀察端的前基板2 1內面）上，順沿行的 方向（圖式的左右方向）形成相互平行之複數掃描電極 2 3，而在屬另一者的後基板2 2內面上，則沿列方向（圖式 的垂直方向）形成相互平行之複數信號電極24。該等 掃描電極23與信號電極24係分別被覆上經朝特定方 向偏向處理的偏向膜（未圖示）。 另，該一對基板21,22在其周緣部位處，利用框狀密封 材料26予以接合，並在由該等基板21,22間之密封材 料26所包圍的區域中，設置液晶層27。 在該一對基板21，22中，屬顯示觀察端的基板之前基 板2 1之一側緣上，形成較另一者之後基板22端緣更向 外突出的端子配接部2 1 a，在此端子配接部2 1 a內面上， 則配接形成分別對應該複數掃描電極2 3的複數掃描端 端子電極25、與分別對應該複數信號電極24的複數 信號端端子電極（未圖示）。 1287159 五、發明説明（7 ) 該等端子電極係形成於由該密封材料2 6之基板接合 部內、或其外緣附近起，橫跨較該透明基板21，22端緣 更朝內側僅內縮特定距離L的區域上，而設置於前基板 2 1內面上的複數掃描電極2 3則分別電性連接於所對 應的該複數掃描端端子電極2 5上。設置於後基板2 2 內面上的複數信號電極2 4係透過譬如混入於密封材料 26中的導電性粒子（未圖示），而分別導通連接於相對應 該前基板2 1內面上所形成的導線（未圖示）上，該等導線 並電性連接於所對應的該複數信號端端子電極上。 再者，此液晶顯示面板20係屬於TN型或STN型，乃 在該一對基板21,22之外面上，分別配置其光軸（吸收軸 或穿透軸）朝特定方向的偏光板28，29,而該液晶層27 的液晶分子則在二基板21，22內面上，利用分別覆蓋該 電極23，24而設置之未圖示的偏向膜，限制各基板 2 1，22附近的偏向方向，而以特定扭轉角扭轉偏向。 再者，液晶顯示面板20若屬利用如陽光、或室內燈 光等電子機器使用環境之光以外的光而進行反射顯示 時，則在配置於其後基板22外面上之後側的偏光板29 的背面上，設置光反射板30。 另，該可撓配線板3 1係在可撓樹脂薄膜的一面上設 置複數配線（未圖示），並在其面上，將供驅動該液晶顯示 面板20之LSI等驅動電路元件32,以其複數輸出入端 子分別連接搭載於該複數配線上。該等複數配線內，該 驅動電路元件3 2之複數輸出端子所分別連接的複數輸 -9- 1287159 五、發明説明（8 ) 出側配線，引導出於該可撓配線板31的一端，並分別配 接對應於該液晶顯示面板20之端子配接部2 1 a上所配 接形成的複數掃描端端子電極25與信號端端子電極上。 然後，該可撓配線板3 1係使配接於其一端上的該複 數輸出端配線，依使分別對向於該液晶顯示面板20之 端子配接部2 1 a的複數掃描端端子電極2 5、與信號端 端子電極呈位置合致狀態，利用非等向導電黏接劑3 3 黏接，而黏接連接於該端子配接部21a上。此處，複數 掃描端端子電極2 5與信號端端子電極，係如前述，因爲 由較端子配接部2 1 a端緣，朝內側（液晶層27端）僅內縮 特定尺寸L的位置起更內側的區域，所以可燒配線板 3 1的一端，亦在較該端子配接部2 1 a端緣更朝內側僅內 縮尺寸L的區域中，利用非等向導電黏接劑3 3橫跨特 定黏接長度W而黏接連接。 再者，該可撓配線板3 1對該液晶顯示面板2 0之端子 配接部2 1 a的黏接連接，係利用可撓配線板3 1，使該可 撓配線板3 1之一端重疊於該端子配接部2 1 a上，利用 未圖示之熱彌封夾具進行加熱壓接。 所以，一端黏接連接於液晶顯示面板20之端子配接 部2 1 a上的可撓配線板3 1，在較該端子配接部2 1 a端緣 更內側中反折，而配置於液晶顯示面板2 0後面。 此處，在本實施例中，該可撓配線板3 1的反折部分，爲 不致在可撓配線板3 1上產生過大應力，而彎，曲呈如圖 所示圓弧狀。 -10- 1287159 五、發明説明（9 ) 所以，在本實施例中，可撓配線板31對該液晶顯示面 板2 0之端子配接部2 1 a的黏接區域，係設定爲由該端 子配接部2 1 a端緣起，向內側靠近相當於該可撓配線板 3 1之反折部分最小曲率半徑之長度以上距離L的區 域。此情況下，所謂的最小曲率半徑，係指可撓配線板 未折垮而維持彎曲狀態時的最小曲率半徑，依底材薄膜 材質而異。藉此，一端連接於該端子配接部2 1 a上的可 撓配線板3 1，便可輕易的圓弧狀反折彎曲於較該端子配 接部2 1 a端緣更內側處。另，當端子配接部2 1 a端緣非 一直線而屬部分凹凸的端緣時，便將可撓配線板在較最 外側端緣更內側處反折。 再者，此顯示模組中，該可撓配線板3 1之一端，因爲在 較該液晶顯示面板20之端子配接部21a端緣，更內縮 於該端子配接部2 1 a內側的區域處，黏接於該端子配接 部2 1 a上，可繞配線板3 1對端子配接部2 1 a黏接長度 W，便較第1圖所示之習知顯示模組的黏接長度爲短。 所以，在本實施例中，由該端子配接部2 1 a之可撓配 線板的黏接區域起，到該液晶顯示面板20之後基板22 端緣間的距離S，便能儘可能的縮短，並能確保將可撓配 線板3 1對該端子配接部2 1 a的黏接長度W儘可能的 增長，而獲得足夠的黏接力。此黏接長度W，若確保在 1 .2醒左右的話便足夠，藉此便可獲得將該可撓配線板 3 1可依足夠強度黏接於前基板2 1之端子配接部2 1 a 上，同時依非等向導電黏接劑3 3的可撓配線板之輸出 -11- 1287159 五、發明説明（1G) 端配線，與端子電極25間之連接部份的電阻抗便可變 得足夠的小。 在此顯示模組中，如上述，因爲將可撓配線板3 1之一 端，在較液晶顯示面板20之端子配線部21a端緣，向該 端子配接部2 1 a內側內縮更長於相當於該可撓配線板 3 1反折部分之曲率半徑（如數百// m左右）的距離L之 區域中，黏接於該端子配接部2 1 a上，而將該可撓配線 板3 1在較該端子配接部2 1 a端緣更內側的位置處反折， 所以該可撓配線板3 1之反折部分便不致由該液晶顯示 面板2 0端緣突出於外側。 所以，在封裝此顯示模組的電子機器中，顯示模組容 納部40,便如第2圖假想線（二點虛線）所示，不再需要 如第1圖所示之習知顯示模組容納部1 5般，亦需要容 納可撓配線板1 2突出部分的較大容納空間1 5a，此部份 便可使整體顯示模組容納部4 0縮小。藉此，安裝本顯 示模組之電子機器便可達小型化之功效。 同時，該顯示模組，由前面所看到的外觀，因爲該可撓 配線板3 1的反折部分並無突出的形狀，所以該液晶顯 示面板20所有的邊緣，更可在毋需設計多餘間隙的情 況下，由周緣支撐於該顯示模組容納部40上。所以，便 可確實限制該液晶顯示面板20沿面方向在所有方向上 的偏移等變動情形發生，而可在無偏移的情況下容納於 該顯示模組容納部40中。 第3圖所示係本發明第2實施例之顯示模組的部分 -12- 1287159 五、發明説明（11 ) 剖面示意圖。此實施例之顯示彳莫，組，係#該可_ κ線板 3 1反折部分的內周，設置供設制其反折形狀的反折引導 構件3 4。另，相關與上述第1貫施例相同的構成要件， 在圖中賦予相同符號，在此便不再贅述。 本實施例之液晶顯示面板2 0 '中，設置於後基板2 2內 面上的信號電極2 4、並非透明電極，而是：由纟呂等所'組成 的光反射板兼具電極。所以，並未如第1實施例般，在 液晶顯示面板20、外側設置反射板。此外，相關偏光板， 則僅設置前端的偏光板2 8，在後基板端則並未配置偏光 板。如此，依照本實施例，因爲未配置反射板與後基板 端的偏光板，所以液晶顯示面板2 0'便可減少該等部分 的厚度而薄型化。藉此，便可將可撓配線板3 1之反折 部分的曲率半徑縮小，而可將端子配接部2 1 a之非黏接 部分的距離L、，較第1 .實施例情況的距離L更加縮短。 結果，便可更促使本實施例之顯示模組與搭載其之電子 機器的輕薄小型化。再者，藉由在液晶顯不面板2 〇s內 部設置光反射板，便可減輕視差，而達提昇顯示畫質之 功效。另，光反射板亦可設置於與信號電極不同的後基 板內面上。 然後，該反折引導構件34係具有幾乎橫跨該可撓配 線板3 1全寬的長度，與由液晶顯示面板20之端子配接 部2 1 a的可撓配線板黏接區域起橫跨該可撓配線板3 1 之反折部分的寬部，同時在一側面上由形成圓弧狀彎曲 凸面的樹脂板所構成，由該彎曲凸面橫跨前後面，被覆 -13- 1287159 五、發明説明（12) 上黏著劑或雙面膠帶35。 此實施例之顯示模組，在該液晶顯示面板20之端子 配接部21a上，透過非等向導電黏接劑33,而重疊上該 可撓配線板3 1之一端，並利用未圖不之熱彌封夾具進 行加熱壓接，而將該可撓配線板3 1黏接連接於該端子 配接部21a上，然後將該反折引導構件34的前面貼合 於該可撓配線板3 1之一端的背面上，之後將該可撓配 線板3 1 —邊壓接於該反折引導構件34的彎曲凸面上， 一邊反折呈圓弧狀，藉由此反折引導構件34的彎曲凸 面與後面之貼合而組合。 本實施例之顯示模組，在該可撓配線板3 1的反折部 分內周，因爲設置有供限制其反折形狀的反折引導構件 34,所以更可確保可撓配線板31的反折部分絕不致突 出於該液晶顯示面板20的外側，同時可將該可撓配線 板3 1的反折形狀，以較小曲率特定化，而達由該液晶顯 示面板20與可撓配線板3 1所組成的顯示模組整體小 型化之功效。另，亦可防止可撓配線板3 1在反折部分 因過度彎曲呈銳角，而產生配線斷線等不良情況的發 生。除此之外，因爲在後基板內面上設置兼具電極用的 光反射板，而未設置光反射板與後側的偏光板，所以便 可使液晶顯示模組顯示面板與使用其之顯示模組，更進 一步趨於小型薄型化。 另，在上述第1實施例與第2實施例中，將配接形成 於液晶顯不面板1之端子配接部2 a上的複數掃描端端 -14- 1287159 五、發明説明（13) 子電極6與信號端端子電極，雖使其端緣形成於由可撓 配線板黏接區域之端子配接部2 1 a端緣起，至內縮特定 距離L或L'的位置爲止間。但，該掃描端端子電極6與 信號端端子電極亦可形成延伸至該端子配接部2 1 a端 緣處。即便此情況下，將可撓配線板3 1之一端，黏接於 將該端子配接部2 1 a端緣向內縮特定距離L的區域中， 並將該可撓配線板3 1在較該端子配接部2 1 a端緣更內 側處反折，藉此便可使可撓配線板3 1的反折部分不致 突出於液晶顯示面板20的外側，由前面端觀之，便可形 成對應該液晶顯示面板20外型的簡單形狀。 再者，可撓配線板3 1亦可將一端側面當作外側，而黏 接於端子配接部2 1 a上，並在此不反折，而僅折曲的將另 一端配置於液晶顯示面板的後面。 再者，採用上述實施例的液晶顯示面板20係屬在後 面具備光反射板3 0的反射型者，而液晶顯示面板則可 爲後面端配置後照燈的穿透型者，亦可爲後面端配置具 光反射功能與照明光射出功能之照明機構的反射/穿透

The line is quite trapped in the sub-h, the sub-film thin film set in the mold-shaped deformation The display group can be shown in the display and the display (4) machine, as shown in the imaginary line of Figure 1 (two-dotted line), the protrusion that can accommodate the flexible wiring board 12 is required. The larger accommodation space 15a of the portion (reflexed portion P) causes a disadvantage that the display module is enlarged. [Invention] In view of the above, an object of the present invention is to provide a flexible wiring board reverse-folding portion that does not protrude outside the display panel, and the display module is easy to assemble, and the mounted electronic device can be appropriately miniaturized. Display module. The display module provided by the present invention has a pair of substrates, a terminal wiring portion, an electro-optical display panel, and a flexible wiring board, and the pair of substrates are in mutually opposing substrates. Forming electrodes on the surface; the terminal mating portion is formed by an electro-optical material disposed between the pair of substrates, and one end of the front substrate is disposed on the front substrate on the display side of the pair of substrates The edge of the substrate is more prominent than the corresponding edge of the substrate opposite to the front substrate; the electro-optical display panel is coupled to the inner surface of the terminal mating portion, and is formed to be electrically connected to the terminal electrode of the electrode; The flexible wiring board is formed with one end of the wiring, electrically connected to the wiring, and the terminal electrode of the electro-optical display panel, and is fixed to the inner surface of the terminal mating portion, and the other end is mated to the terminal. The outermost edge of the outermost portion is bent in the inner side and is disposed behind the electro-optical display panel. In the display module, since the flexible wiring board is folded back in an area further inside than the outermost edge of the terminal fitting portion, the folded portion of the flexible wiring board does not protrude from the outside of the panel. Therefore, it is easy to assemble on the machine of the electronic 6- 1287159 5, invention description (5), and the installed electronic device can also be miniaturized. In the display module provided by the present invention, the area to which one end of the flexible wiring board is to be connected is preferably set to an outermost edge of the terminal fitting portion of the display panel, and only a region of a certain distance is contracted. In this case, the flexible wiring board is preferably folded back in a region further inside than the outermost edge of the terminal fitting portion. Thus, by folding back, the flexible wiring board is less likely to be peeled off by the terminal fitting portion. Therefore, when the flexible wiring board is folded back, it is preferable to provide a folding guide member for restricting the shape of the folded portion on the inner surface of the folded portion. Therefore, the reflexed portion of the flexible wiring board can be more surely not protruded from the outside of the display panel, and the reflexed shape of the flexible wiring board can be made constant to form a display panel and a flexible wiring board. The overall display module shape can achieve the same shape normalization effect when mass production of a large number of display modules. Furthermore, the present invention is applicable to a liquid crystal display module using an electro-optical material as a liquid crystal, and more preferably used in a reflective liquid crystal display module which is strongly required to be miniaturized. Therefore, when used in a reflective liquid crystal display module, the light reflecting plate is disposed on the inner surface of the rear substrate, or the electrode disposed on the inner surface of the rear substrate is also used as a reflecting plate, which can be further promoted. In addition to the miniaturization of the liquid crystal display module, the enamel can enhance the effect of the reflective display image quality.

In the pair of substrates 21, 22, on one side edge of the substrate 21 before the substrate showing the observation end, a terminal fitting portion 2 1 a which protrudes more outward than the edge of the substrate 22 is formed. On the inner surface of the terminal fitting portion 2 1 a, a plurality of scanning terminal electrode electrodes 25 corresponding to the plurality of scanning electrodes 23 and a plurality of signal terminal electrode electrodes corresponding to the plurality of signal electrodes 24 (not shown) are respectively provided. . 1287159 V. INSTRUCTION OF THE INVENTION (7) The terminal electrodes are formed in the substrate joint portion of the sealing material 26 or in the vicinity of the outer edge thereof, and are only retracted from the edge of the transparent substrate 21, 22 toward the inner side. The plurality of scanning electrodes 23 disposed on the inner surface of the front substrate 21 are electrically connected to the corresponding plurality of scanning terminal electrodes 25, respectively. The plurality of signal electrodes 24 disposed on the inner surface of the rear substrate 2 2 are transparently connected to the conductive particles (not shown) mixed in the sealing material 26, and are respectively electrically connected to the inner surfaces of the corresponding front substrate 2 1 . The wires (not shown) are electrically connected to the corresponding plurality of signal terminal electrodes. Further, the liquid crystal display panel 20 is of a TN type or an STN type, and a polarizing plate 28 whose optical axis (absorption axis or transmission axis) is directed to a specific direction is disposed on the outer faces of the pair of substrates 21, 22, respectively. 29, the liquid crystal molecules of the liquid crystal layer 27 are disposed on the inner surfaces of the two substrates 21, 22 by a deflecting film (not shown) provided to cover the electrodes 23, 24, respectively, to restrict the deflection direction in the vicinity of each of the substrates 2 1, 22 And twist the deflection at a specific twist angle. In addition, when the liquid crystal display panel 20 is reflected and displayed by light other than light of an electronic device such as sunlight or indoor lighting, the back surface of the polarizing plate 29 disposed on the outer surface of the rear substrate 22 is disposed. Above, a light reflecting plate 30 is provided. Further, the flexible wiring board 31 is provided with a plurality of wirings (not shown) on one surface of the flexible resin film, and a driving circuit element 32 such as an LSI for driving the liquid crystal display panel 20 is provided on the surface thereof. The plurality of input/output terminals are connected and mounted on the plurality of wires. In the plurality of wirings, a plurality of output terminals of the plurality of output terminals of the driving circuit element 32 are connected to each other, and the outlet is wired to one end of the flexible wiring board 31, and The plurality of scanning terminal electrodes 25 and the signal terminal electrodes that are formed to be connected to the terminal mating portions 2 1 a of the liquid crystal display panel 20 are respectively coupled. Then, the flexible wiring board 31 is connected to the plurality of output terminals of the liquid crystal display panel 20, and the plurality of scanning terminal electrodes 2 are respectively aligned with the terminal mating portions 2 1 a of the liquid crystal display panel 20 5. Positioned in a position with the signal terminal electrode, and bonded by the non-isotropic conductive adhesive 3 3 , and bonded and connected to the terminal mating portion 21a. Here, the plurality of scanning end terminal electrodes 25 and the signal terminal electrode are as described above, because the end of the terminal fitting portion 2 1 a is inwardly (the liquid crystal layer 27 end) is only retracted from the position of the specific size L. In the inner side region, one end of the burnable wiring board 3 1 is also used in the region of the inner side of the terminal mating portion 2 1 a which is only inwardly retracted by the dimension L, and the non-isotropic conductive adhesive 3 3 is used. Bonding is made across a specific bond length W. Further, the flexible wiring board 3 1 is bonded to the terminal fitting portion 2 1 a of the liquid crystal display panel 20, and one end of the flexible wiring board 31 is overlapped by the flexible wiring board 31. The terminal fitting portion 2 1 a is heated and pressure-bonded by a heat sealing jig (not shown). Therefore, the flexible wiring board 3 1 that is bonded to the terminal mating portion 2 1 a of the liquid crystal display panel 20 at one end is folded back in the inner side of the end edge of the terminal mating portion 2 1 a, and is disposed in the liquid crystal. Display panel 2 0 behind. Here, in the present embodiment, the folded portion of the flexible wiring board 31 is such that it does not cause excessive stress on the flexible wiring board 31, and the curved portion has an arc shape as shown in the figure. -10- 1287159 V. Inventive Note (9) Therefore, in the present embodiment, the bonding area of the flexible wiring board 31 to the terminal fitting portion 2 1 a of the liquid crystal display panel 20 is set to be the terminal. The end of the mating portion 2 1 a is close to the inner side of the region corresponding to the length L of the minimum radius of curvature of the folded portion of the flexible wiring board 3 1 . In this case, the minimum radius of curvature refers to the minimum radius of curvature when the flexible wiring board is not bent and maintained in a curved state, and varies depending on the material of the substrate film. Thereby, the flexible wiring board 3 1 connected to the terminal fitting portion 2 1 a at one end can be easily bent in an arc shape and bent at the inner side of the end edge of the terminal fitting portion 2 1 a. Further, when the end edge of the terminal fitting portion 2 1 a is not a straight line and belongs to the end edge of the uneven portion, the flexible wiring board is folded at the inner side of the outermost edge. In the display module, one end of the flexible wiring board 31 is further recessed inside the terminal mating portion 21a than the end of the terminal mating portion 21a of the liquid crystal display panel 20. The area is adhered to the terminal mating portion 2 1 a, and the length W can be adhered to the terminal mating portion 2 1 a around the wiring board 3 1 , which is more adhesive than the conventional display module shown in FIG. 1 . The connection length is short. Therefore, in the present embodiment, the distance S between the end edges of the substrate 22 after the liquid crystal display panel 20 is shortened by the bonding area of the flexible wiring board of the terminal mating portion 2 1 a And it is ensured that the bonding length W of the flexible wiring board 31 to the terminal fitting portion 2 1 a is increased as much as possible to obtain a sufficient adhesive force. The bonding length W is sufficient if it is ensured to be around 1.2, whereby the flexible wiring board 3 1 can be adhered to the terminal fitting portion 2 1 a of the front substrate 2 1 with sufficient strength. The output of the flexible wiring board of the non-isodirectional conductive adhesive 3 3 is also -11- 1287159. 5. The invention (1G) terminal wiring, the electrical resistance of the connection portion with the terminal electrode 25 can become Small enough. In the display module, as described above, since one end of the flexible wiring board 31 is at the end of the terminal wiring portion 21a of the liquid crystal display panel 20, the inner side of the terminal fitting portion 2 1 a is retracted longer than the equivalent. And in the region of the distance L of the radius of curvature of the folded portion of the flexible wiring board 31 (for example, about several hundred / / m), the terminal mating portion 2 1 a is adhered to the flexible wiring board 3 1 is folded at a position further inside than the end edge of the terminal mating portion 2 1 a , so that the folded portion of the flexible wiring board 3 1 does not protrude from the outer edge of the liquid crystal display panel 20 edge. Therefore, in the electronic device in which the display module is packaged, the module housing portion 40 is displayed, as shown in the imaginary line of FIG. 2 (two-dotted line), the conventional display module as shown in FIG. 1 is no longer needed. In the same manner as the accommodating portion 15, a large accommodating space 15a for accommodating the protruding portion of the flexible wiring board 12 is required, and this portion can reduce the overall display module housing portion 40. In this way, the electronic device on which the display module is mounted can be miniaturized. At the same time, the display module has the appearance as seen from the front. Since the folded portion of the flexible wiring board 31 has no protruding shape, all the edges of the liquid crystal display panel 20 can be redundantly designed. In the case of a gap, it is supported by the display module housing portion 40 by the periphery. Therefore, it is possible to surely restrict the occurrence of variations in the displacement of the liquid crystal display panel 20 in all directions in the plane direction, and to accommodate the display module housing portion 40 without offset. Fig. 3 is a cross-sectional view showing a portion of a display module according to a second embodiment of the present invention, -12-1287159, and a description of the invention (11). In the embodiment shown in Fig. 1, the inner circumference of the reversing portion of the _ κ line plate 3 1 is provided with a reflex guide member 34 for providing a reversely folded shape. The same components as those in the above-described first embodiment are denoted by the same reference numerals and will not be described again. In the liquid crystal display panel 20' of the present embodiment, the signal electrode 24 provided on the inner surface of the rear substrate 2 2 is not a transparent electrode, but the light reflecting plate composed of the ruthenium or the like has an electrode. Therefore, as in the first embodiment, the reflection plate is not provided on the liquid crystal display panel 20 and on the outer side. Further, in the case of the relevant polarizing plate, only the polarizing plate 2 at the front end is provided, and the polarizing plate is not disposed at the rear substrate end. As described above, according to the present embodiment, since the reflecting plate and the polarizing plate at the rear substrate end are not disposed, the liquid crystal display panel 20' can be made thinner by reducing the thickness of the portions. Thereby, the radius of curvature of the folded portion of the flexible wiring board 31 can be reduced, and the distance L of the non-adhered portion of the terminal fitting portion 2 1 a can be made smaller than that of the first embodiment. L is even shorter. As a result, the display module of the present embodiment and the electronic device on which it is mounted can be further reduced in size and size. Furthermore, by providing a light reflecting plate inside the liquid crystal display panel 2 〇s, the parallax can be reduced, and the display quality can be improved. Alternatively, the light reflecting plate may be disposed on the inner surface of the rear substrate different from the signal electrode. Then, the folding guide member 34 has a length that is almost wide across the flexible wiring board 31, and spans from the flexible wiring board bonding area of the terminal fitting portion 2 1 a of the liquid crystal display panel 20. The wide portion of the folded-back portion of the flexible wiring board 3 1 is composed of a resin plate forming an arc-shaped curved convex surface on one side surface, and the curved convex surface is covered across the front and back, and is covered - 13 - 1287159 Description (12) Upper adhesive or double-sided tape 35. The display module of this embodiment is configured to pass through the non-equal conductive adhesive 33 on the terminal mating portion 21a of the liquid crystal display panel 20, and overlap one end of the flexible wiring board 31, and use the unillustrated The heat sealing clamp is heated and crimped, and the flexible wiring board 31 is adhesively connected to the terminal fitting portion 21a, and then the front surface of the folding guide member 34 is attached to the flexible wiring board 3. On the back surface of one end, the flexible wiring board 3 1 is then crimped to the curved convex surface of the folding guide member 34, and is folded back in an arc shape, whereby the bending of the guiding member 34 is reversed. The convex surface is combined with the back. In the display module of the present embodiment, in the inner periphery of the folded portion of the flexible wiring board 31, since the folding guide member 34 for restricting the reversely folded shape is provided, the reverse of the flexible wiring board 31 can be ensured. The folded portion is never protruded from the outer side of the liquid crystal display panel 20, and the folded shape of the flexible wiring board 31 can be specified with a small curvature to reach the liquid crystal display panel 20 and the flexible wiring board 3. The overall compactness of the display module consisting of one. Further, it is possible to prevent the flexible wiring board 31 from being acutely bent at an excessively bent portion due to excessive bending, thereby causing a problem such as a disconnection of the wiring. In addition, since the light reflecting plate for the electrode is provided on the inner surface of the rear substrate, and the light reflecting plate and the polarizing plate on the rear side are not provided, the liquid crystal display module display panel and the display using the same can be provided. Modules are further slimmer and thinner. Further, in the first embodiment and the second embodiment, the plurality of scanning end ends 14 to 1287159 which are formed on the terminal fitting portion 2a of the liquid crystal display panel 1 are attached, and the invention (13) The electrode 6 and the signal terminal electrode have their end edges formed at the end of the terminal fitting portion 2 1 a from the flexible wiring board bonding region to a position where the specific distance L or L' is contracted. However, the scanning terminal electrode 6 and the signal terminal electrode may also be formed to extend to the end edge of the terminal fitting portion 2 1 a . Even in this case, one end of the flexible wiring board 31 is adhered to a region where the end edge of the terminal mating portion 2 1 a is inwardly contracted by a specific distance L, and the flexible wiring board 3 1 is compared. The end of the terminal mating portion 2 1 a is folded at the inner side, so that the folded portion of the flexible wiring board 3 1 does not protrude from the outer side of the liquid crystal display panel 20, and can be formed by the front end. A simple shape corresponding to the appearance of the liquid crystal display panel 20. Furthermore, the flexible wiring board 3 1 can also have one end side as the outer side, and can be adhered to the terminal mating portion 2 1 a , and does not fold back here, but only bends the other end and is disposed on the liquid crystal display. Behind the panel. Furthermore, the liquid crystal display panel 20 of the above embodiment is a reflective type having a light reflecting plate 30 at the rear, and the liquid crystal display panel can be a penetrating type of a rear light, or a rear side. The reflection/penetration type of the illumination mechanism having the light reflection function and the illumination light emission function may be disposed at the rear end, and the front end may be provided with a reflection type that emits light toward the illumination mechanism of the liquid crystal display panel. Furthermore, the liquid crystal display panel is not limited to a simple matrix method, and may be an active matrix method or a segmentation method. Further, it is not limited to the TN type or the STN type, and may be a guest type, a scattered effect type, or a QS1 type using a display operation of a lateral electric field. Furthermore, in the above embodiment, although the display panel uses a liquid crystal display surface -15- 1287159 5, the invention description (14) board, the display panel may also be an electro-optical material layer such as electrophoresis or electricity. Optical display panel.
