図１は、実施形態に係る表示装置１の屈曲前の状態を示す斜視図である。図２は、表示装置１の屈曲後の状態を示す斜視図である。表示装置１は、例えば有機発光ダイオードを表示素子として含む有機ＥＬ表示装置である。表示装置１は、可撓性を有するフィルムを基材として用いた屈曲可能な表示パネル１０を備えている。可撓性を有するフィルムは、例えばポリイミドなどの合成樹脂材料で形成される。   FIG. 1 is a perspective view illustrating a state of the display device 1 according to the embodiment before bending. FIG. 2 is a perspective view showing the display device 1 after being bent. The display device 1 is an organic EL display device including, for example, an organic light emitting diode as a display element. The display device 1 includes a bendable display panel 10 using a flexible film as a base material. The flexible film is formed of a synthetic resin material such as polyimide, for example.

表示パネル１０は、第１表示領域Ａ１と、第１表示領域Ａ１から離れた第２表示領域Ａ２と、第１表示領域Ａ１と第２表示領域Ａ２との間に位置する隙間領域Ｃと、第１表示領域Ａ１、第２表示領域Ａ２及び隙間領域Ｃを囲む額縁領域Ｂとを有している。   The display panel 10 includes a first display area A1, a second display area A2 away from the first display area A1, a gap area C positioned between the first display area A1 and the second display area A2, It has a display area A1, a second display area A2, and a frame area B surrounding the gap area C.

図中のＸ方向は、第１表示領域Ａ１、隙間領域Ｃ及び第２表示領域Ａ２が並ぶ方向を表し、Ｙ方向は、Ｘ方向に交差（例えば直交）する方向を表している。Ｘ方向のうち、第１表示領域Ａ１又は第２表示領域Ａ２に対する隙間領域Ｃの方向を内側とし、その反対を外側とする。また、図中のＦ方向は表示面側を表し、Ｒ方向は裏面側を表している。   The X direction in the figure represents the direction in which the first display area A1, the gap area C, and the second display area A2 are arranged, and the Y direction represents a direction that intersects (eg, is orthogonal to) the X direction. Among the X directions, the direction of the gap region C with respect to the first display region A1 or the second display region A2 is defined as the inside, and the opposite is defined as the outside. Further, the F direction in the figure represents the display surface side, and the R direction represents the back surface side.

表示領域Ａには、例えば赤、緑及び青からなる複数色の単位画素（サブピクセル）を組み合わせたフルカラーの画素がマトリクス状に配列している。額縁領域Ｂには周辺回路が配置されてもよい。また、表示パネル１０は、ＦＰＣ（フレキシブルプリント基板）等が接続される不図示の端子領域も有している。端子領域は、例えば額縁領域Ｂの外側に設けられ、裏面側に折り返される。   In the display area A, for example, full-color pixels in which a plurality of color unit pixels (sub-pixels) made of red, green, and blue are combined are arranged in a matrix. A peripheral circuit may be arranged in the frame area B. The display panel 10 also has a terminal area (not shown) to which an FPC (flexible printed circuit board) or the like is connected. The terminal region is provided outside the frame region B, for example, and is folded back to the back side.

隙間領域Ｃは、屈曲可能とされている。本例では、隙間領域Ｃは裏面側に屈曲可能である。すなわち、隙間領域Ｃは、第１表示領域Ａ１及び第２表示領域Ａ２の裏面同士が向かい合うように屈曲可能である。これにより、表示装置１は裏面側に折り畳み可能とされている。   The gap region C can be bent. In this example, the gap region C can be bent to the back side. That is, the gap area C can be bent so that the back surfaces of the first display area A1 and the second display area A2 face each other. Thereby, the display apparatus 1 can be folded to the back side.

図３は、図１に示すＩＩＩ−ＩＩＩ線で切断したときの断面図である。同図は、裏面側に折り畳み可能な表示装置１の例を示している。   3 is a cross-sectional view taken along the line III-III shown in FIG. The figure shows an example of the display device 1 that can be folded to the back side.

表示パネル１０は、基材２上に回路層１４、素子層１６及び封止膜１８を有している。回路層１４は、各単位画素に対応する薄膜トランジスタを含んでいる。素子層１６は、各単位画素に対応する有機発光ダイオードを含んでいる。   The display panel 10 has a circuit layer 14, an element layer 16, and a sealing film 18 on the substrate 2. The circuit layer 14 includes a thin film transistor corresponding to each unit pixel. The element layer 16 includes an organic light emitting diode corresponding to each unit pixel.

表示パネル１０上（すなわち表示面側）にはタッチパネル２０が配置されている。タッチパネル２０は、表示パネル１０の第１表示領域Ａ１及び第２表示領域Ａ２上だけでなく、隙間領域Ｃ上にも配置されている。タッチパネル２０は、屈曲可能とするため、例えば金属材料で形成された網目状配線（メッシュ配線）を含むことが好ましい。タッチパネル２０はオンセルであっても外付けであってもよい。タッチパネル２０は省略されてもよい。   A touch panel 20 is disposed on the display panel 10 (that is, on the display surface side). The touch panel 20 is disposed not only on the first display area A1 and the second display area A2 of the display panel 10 but also on the gap area C. The touch panel 20 preferably includes a mesh-like wiring (mesh wiring) formed of, for example, a metal material so that the touch panel 20 can be bent. The touch panel 20 may be on-cell or external. The touch panel 20 may be omitted.

タッチパネル２０上には円偏光板３３が配置されている。円偏光板３３は、表示パネル１０の第１表示領域Ａ１及び第２表示領域Ａ２上だけでなく、隙間領域Ｃ上にも配置されている。   A circularly polarizing plate 33 is disposed on the touch panel 20. The circularly polarizing plate 33 is disposed not only on the first display area A1 and the second display area A2 of the display panel 10 but also on the gap area C.

円偏光板３３上には第１及び第２カバーガラス３５Ａ，３５Ｂが配置されている。第１及び第２カバーガラス３５Ａ，３５Ｂは、第１及び第２透明基板の例である。第１カバーガラス３５Ａは、表示パネル１０の第１表示領域Ａ１上に設けられ、第１表示領域Ａ１を屈曲しないように支持している。第２カバーガラス３５Ｂは、表示パネル１０の第２表示領域Ａ２上に設けられ、第２表示領域Ａ２を屈曲しないように支持している。第１及び第２カバーガラス３５Ａ，３５Ｂは、隙間領域Ｃ上には設けられていない。   On the circularly polarizing plate 33, first and second cover glasses 35A and 35B are disposed. The first and second cover glasses 35A and 35B are examples of first and second transparent substrates. The first cover glass 35A is provided on the first display area A1 of the display panel 10, and supports the first display area A1 so as not to bend. The second cover glass 35B is provided on the second display area A2 of the display panel 10, and supports the second display area A2 so as not to bend. The first and second cover glasses 35A and 35B are not provided on the gap region C.

第１カバーガラス３５Ａは、第１粘着シート３４Ａにより円偏光板３３に貼り付けられている。第２カバーガラス３５Ｂは、第２粘着シート３４Ｂにより円偏光板３３に貼り付けられている。   The first cover glass 35A is attached to the circularly polarizing plate 33 by the first adhesive sheet 34A. The second cover glass 35B is attached to the circularly polarizing plate 33 by the second adhesive sheet 34B.

表示パネル１０の隙間領域Ｃ上には保護膜３７が設けられている。保護膜３７は、第１カバーガラス３５Ａと第２カバーガラス３５Ｂとの間に設けられている。具体的には、保護膜３７は、第１カバーガラス３５Ａと第２カバーガラス３５Ｂとの間に形成された溝を埋めている。保護膜３７は、第１又は第２カバーガラス３５Ａ，３５ＢのＸ方向内側の縁３５１に接している。保護膜３７の上面は、第１又は第２カバーガラス３５Ａ，３５Ｂの上面よりも低い。保護膜３７は、第１又は第２粘着シート３４Ａ，３４Ｂのうち、第１又は第２カバーガラス３５Ａ，３５ＢのＸ方向内側の縁３５１よりもＸ方向内側にはみ出した部分を覆っている。   A protective film 37 is provided on the gap region C of the display panel 10. The protective film 37 is provided between the first cover glass 35A and the second cover glass 35B. Specifically, the protective film 37 fills a groove formed between the first cover glass 35A and the second cover glass 35B. The protective film 37 is in contact with the inner edge 351 of the first or second cover glass 35A, 35B in the X direction. The upper surface of the protective film 37 is lower than the upper surfaces of the first or second cover glasses 35A and 35B. The protective film 37 covers a portion of the first or second adhesive sheet 34A, 34B that protrudes inward in the X direction from the edge 351 on the inner side in the X direction of the first or second cover glass 35A, 35B.

保護膜３７は、第１及び第２カバーガラス３５Ａ，３５Ｂよりも軟らかく、弾性を有しており、隙間領域Ｃとともに屈曲可能である。また、保護膜３７は透明であり、隙間領域Ｃが発光する場合、隙間領域Ｃからの光を透過する。保護膜３７は、例えばエポキシ樹脂などの合成樹脂材料で形成される。保護膜３７は、例えば液状の合成樹脂材料を塗布し、硬化させることによって形成される。   The protective film 37 is softer than the first and second cover glasses 35A and 35B, has elasticity, and can be bent together with the gap region C. The protective film 37 is transparent, and transmits light from the gap region C when the gap region C emits light. The protective film 37 is formed of a synthetic resin material such as an epoxy resin, for example. The protective film 37 is formed, for example, by applying and curing a liquid synthetic resin material.

表示パネル１０の裏面側には第１及び第２裏面フィルム２１Ａ，２１Ｂが配置されている。第１裏面フィルム２１Ａは、表示パネル１０の第１表示領域Ａ１の裏面側に設けられている。第２裏面フィルム２１Ｂは、表示パネル１０の第２表示領域Ａ２の裏面側に設けられている。第１及び第２裏面フィルム２１Ａ，２１Ｂは、隙間領域Ｃの裏面側には設けられていない。   First and second back films 21 </ b> A and 21 </ b> B are disposed on the back side of the display panel 10. The first back film 21 </ b> A is provided on the back side of the first display area A <b> 1 of the display panel 10. The second back film 21 </ b> B is provided on the back side of the second display area A <b> 2 of the display panel 10. The first and second back films 21A and 21B are not provided on the back side of the gap region C.

以下の説明では、第１及び第２カバーガラス３５Ａ，３５Ｂを総称してカバーガラス３５ともいい、第１及び第２粘着シート３４Ａ，３４Ｂを総称して粘着シート３４ともいい、第１及び第２裏面フィルム２１Ａ，２１Ｂを総称して裏面フィルム２１ともいう。   In the following description, the first and second cover glasses 35A and 35B are collectively referred to as the cover glass 35, and the first and second adhesive sheets 34A and 34B are collectively referred to as the adhesive sheet 34. The back films 21A and 21B are also collectively referred to as the back film 21.

本例では、裏面フィルム２１のＸ方向内側の縁２１１は、カバーガラス３５のＸ方向内側の縁３５１よりもＸ方向内側に位置することが好ましい。すなわち、裏面フィルム２１のＸ方向内側の縁２１１の位置Ｐ２は、カバーガラス３５のＸ方向内側の縁３５１の位置Ｐ５よりもＸ方向内側に位置することが好ましい。これによると、隙間領域Ｃを裏面側に屈曲したときに裏面フィルム２１の縁２１１が表示面側に及ぼす応力を、カバーガラス３５ではなく弾性を有する保護膜３７に集中させることが可能であり、その結果、カバーガラス３５の剥がれを抑制することが可能である。   In this example, the X-direction inner edge 211 of the back film 21 is preferably located on the X-direction inner side of the X-inner edge 351 of the cover glass 35. That is, the position P2 of the inner edge 211 of the back film 21 in the X direction is preferably located on the inner side in the X direction than the position P5 of the inner edge 351 of the cover glass 35 in the X direction. According to this, it is possible to concentrate the stress exerted on the display surface side by the edge 211 of the back film 21 when the gap region C is bent on the back surface side, not on the cover glass 35 but on the elastic protective film 37. As a result, it is possible to suppress peeling of the cover glass 35.

また、本例では、裏面フィルム２１のＸ方向内側の縁２１１は、粘着シート３４のＸ方向内側の縁３４１よりもＸ方向内側に位置することが好ましい。すなわち、裏面フィルム２１のＸ方向内側の縁２１１の位置Ｐ２は、粘着シート３４のＸ方向内側の縁３４１の位置Ｐ４よりもＸ方向内側に位置することが好ましい。これによると、隙間領域Ｃを裏面側に屈曲したときに裏面フィルム２１の縁２１１が表示面側に及ぼす応力を、保護膜３７のうちの粘着シート３４を覆っていない部分に集中させることが可能であり、その結果、粘着シート３４の剥がれを抑制することが可能である。   In this example, it is preferable that the edge 211 on the inner side in the X direction of the back film 21 is located on the inner side in the X direction than the edge 341 on the inner side in the X direction of the adhesive sheet 34. In other words, the position P2 of the inner edge 211 of the back film 21 in the X direction is preferably located on the inner side in the X direction than the position P4 of the inner edge 341 of the adhesive sheet 34. According to this, when the gap region C is bent to the back surface side, the stress exerted on the display surface side by the edge 211 of the back film 21 can be concentrated on the portion of the protective film 37 that does not cover the adhesive sheet 34. As a result, it is possible to suppress peeling of the pressure-sensitive adhesive sheet 34.

また、本例では、粘着シート３４のＸ方向内側の縁３４１は、カバーガラス３５のＸ方向内側の縁３５１よりもＸ方向内側に位置することが好ましい。すなわち、粘着シート３４のＸ方向内側の縁３４１の位置Ｐ４は、カバーガラス３５のＸ方向内側の縁３５１の位置Ｐ５よりもＸ方向内側に位置することが好ましい。これによると、カバーガラス３５の下面を縁３５１の位置まで粘着シート３４に貼り付けることが可能であり、その結果、カバーガラス３５が縁３５１の位置から剥がれることを抑制することが可能である。   In this example, it is preferable that the X direction inner edge 341 of the pressure-sensitive adhesive sheet 34 is located on the X direction inner side of the cover glass 35 on the X direction inner edge 351. That is, it is preferable that the position P4 of the X direction inner edge 341 of the adhesive sheet 34 is located on the X direction inner side than the position P5 of the X direction inner edge 351 of the cover glass 35. According to this, it is possible to affix the lower surface of the cover glass 35 to the adhesive sheet 34 to the position of the edge 351, and as a result, it is possible to suppress the cover glass 35 from being peeled off from the position of the edge 351.

図４は、表示面側に屈曲可能な表示装置１の例を示す断面図である。上記の例と重複する構成については、同番号を付すことで詳細な説明を省略する。   FIG. 4 is a cross-sectional view illustrating an example of the display device 1 that can be bent toward the display surface side. About the structure which overlaps with said example, detailed description is abbreviate | omitted by attaching | subjecting the same number.

本例では、隙間領域Ｃは表示面側に屈曲可能である。すなわち、隙間領域Ｃは、第１表示領域Ａ１及び第２表示領域Ａ２の表示面同士が向かい合うように屈曲可能である。これにより、表示装置１は表示面側に折り畳み可能とされている。   In this example, the gap area C can be bent toward the display surface. That is, the gap area C can be bent so that the display surfaces of the first display area A1 and the second display area A2 face each other. Thereby, the display apparatus 1 can be folded to the display surface side.

また、本例では、カバーガラス３５のＸ方向内側の縁３５１は、裏面フィルム２１のＸ方向内側の縁２１１よりも内側に位置することが好ましい。すなわち、カバーガラス３５のＸ方向内側の縁３５１の位置Ｐ５は、裏面フィルム２１のＸ方向内側の縁２１１の位置Ｐ２よりもＸ方向内側に位置することが好ましい。隙間領域Ｃを表示面側に屈曲したときにカバーガラス３５の縁３５１が裏面側に及ぼす応力を、裏面フィルム２１がない位置に集中させることが可能であり、その結果、裏面フィルム２１の剥がれを抑制することが可能である。   In this example, the X direction inner edge 351 of the cover glass 35 is preferably located inside the X direction inner edge 211 of the back film 21. That is, the position P5 of the inner edge 351 of the cover glass 35 in the X direction is preferably located on the inner side in the X direction than the position P2 of the inner edge 211 of the back film 21 in the X direction. It is possible to concentrate the stress exerted on the back surface by the edge 351 of the cover glass 35 when the gap region C is bent toward the display surface side, and as a result, the back film 21 is peeled off. It is possible to suppress.
