The panel 200 includes a display area 201 in which information and the like can be displayed.

[0036] The first housing 510L is a pulling mechanism for pulling one end 200L of the display panel 200. The storage section 520L including the structure 521L and the space for storing the display panel 200, and the storage section 5 20L (see FIG. 2(A)).

[0037] Moreover, the display panel 200 is pulled out from the storage section 520L through the opening 515L. The display panel 200 is unfolded in response to the opening operation of the folding mechanism 550, and is folded in response to the closing operation of the folding mechanism 550. The other end 200R is connected to the second housing 510R so as to be stored in the second housing 510R (FIG. 1(A)). (See Figure 1(C)).

[0038] This allows the flexible display panel 200 to be stored in the storage section 520L from the end 200L side. In addition, the display panel 200 can be folded while controlling the angle of the display panel 200 relative to the housing. In addition, it is possible to prevent the display panel 200 from being damaged due to excessive stress. Cut.

[0039] In the display device 500 illustrated in this embodiment, the second housing 510R is a display panel 20. 0, a traction mechanism for traction the other end 200R of the display panel 200, and a storage space including a space for storing the display panel 200. 1 and 3, the storage section 520R is connected to the opening 515R. (See (A)).

[0040] As a result, the flexible display panel 200 is inserted into the storage section 520L from the end 200L side, The display panel 200 can be stored in the storage section 520R from the 0R side. In addition, excessive stress can be prevented from being applied to the display panel 200. In addition, defects that could result in destruction can be prevented.

[0041] As a result, a novel display device 500 that is foldable and highly portable can be provided. Therefore, a novel display device 500 capable of displaying images on a seamless large screen can be provided. .

[0042] In addition, in the display device 500 exemplified in this embodiment, the first housing 510L is transparent to visible light. The display panel 200 stored in the storage section 520L can be observed through the window 518L. Position the device in position (see Figure 1(C)).

[0043] As a result, the display panel stored in the storage section 520L of the display device 500 in the folded state Display area 201 of panel 200 can be observed through window 518L.

[0044] As a result, a novel display device 500 that is foldable and highly portable can be provided. Therefore, a novel display device 500 capable of displaying images on a seamless large screen can be provided. Alternatively, a novel display device 500 that allows information to be viewed in a folded state is provided. Can be provided.

[0045] Hereinafter, each element constituting the display device according to one embodiment of the present invention will be described. Storage section The storage section 520L has a space for storing the traction mechanism 521L and the display panel 200 ( The space only needs to be large enough to accommodate the display panel 200. The display panel 200 is stored in a folded or rolled state. That's fine too.

[0046] 《Traction mechanism》 The traction mechanism 521L traction the edge 200L of the display panel 200. For example, a tension spring, a winding device, etc. may be used.

[0047] For example, a tension spring having one end fixed to the first housing 510L is used as a traction mechanism 521L. The other end of the tension spring can be connected to the edge 200L of the display panel 200. According to this configuration, the more the display panel 200 is pulled out from the opening 515L, the As a result, the tension spring pulls the display panel 200 into the storage section 52.

[0052] As a result, the radius of curvature of the display panel 200 being pulled is set to be smaller than the radius of curvature of the guide 516L. This prevents bending and excessive stress. This can prevent the display panel 200 from being damaged.

[0053] In addition, instead of the guide 516L, a cylindrical guide 516L(2) that is supported so as to be freely rotatable is used. (See FIG. 2(B)). The guide 516L(2) can be supported rotatably. As a result, the friction caused by the guide 516L(2) rubbing against the rear surface of the display panel 200 can be reduced. can.

[0054] In addition, it is preferable that the radius of the cylindrical guide 516L(2) is 1 mm or more and 10 mm or less. stomach.

[0055] "window" Window 518L transmits visible light.

[0221] <Display section> The display unit 401 includes a plurality of pixels arranged in a matrix. It includes a pixel circuit that drives the element.

[0222] 《Pixel Structure》 The pixel includes a sub-pixel 402R, which comprises a light-emitting module 480R.

[0223] The subpixel 402R supplies power to the first light-emitting element 450R and the second light-emitting element 450R. The pixel circuit includes a transistor 402t that can

[0224] The light emitting module 480R includes a first light emitting element 450R and an optical element (e.g., a first color layer 467R).

[0225] The first light emitting element 450R includes a lower electrode, an upper electrode, and a light emitting element between the lower electrode and the upper electrode. The organic compound is included in the layer.

[0226] The light emitting module 480R has a first colored layer 467R in the direction in which the light is extracted. The light emitting element may transmit light having a specific wavelength, for example, red, green, or blue. In addition, in other sub-pixels, a material that selectively transmits light that is emitted from the other sub-pixels can be used. A region that transmits the light emitted by the optical element as it is may be provided.

[0227] The first colored layer 467R is located so as to overlap with the first light emitting element 450R. The first light-emitting element 450R shown in FIG. 1 emits light toward the side where the transistor 402t is provided. As a result, a part of the light emitted by the first light emitting element 450R passes through the first colored layer 467R. The light is transmitted and emitted to the outside of light emitting module 480R in the direction of the arrow shown in the figure.

[0228] Display Configuration The display unit 401 has a light-shielding layer 467BM in the light-emitting direction. The light-shielding layer 467BM is It is provided so as to surround a colored layer (for example, the first colored layer 467R).

[0229] The display unit 401 includes an insulating film 421. The insulating film 421 covers the transistor 402t. The insulating film 421 is used as a layer for flattening unevenness caused by the pixel circuit. In addition, a laminated film including a layer capable of suppressing the diffusion of impurities can be applied to the insulating film 421. This can prevent, for example, unexpected impurities diffusing from the first color layer 467R. This can suppress deterioration in reliability of the transistors 402t and the like due to the above-mentioned problems.

[0230] <Touch sensor> The touch sensor 495 is provided on the substrate 410 side of the display unit 401 (see FIG. 7A). ).

[0231] The resin layer 497 is disposed between the substrate 410 and the substrate 490, and is configured to connect the display unit 401 and the touch sensor 49 Paste 5 together.

[0232] <Display section modification example 1> Various transistors can be used for the display portion 401 .

[0233] A structure in which a bottom-gate transistor is applied to the display portion 401 is shown in FIG. This is illustrated in FIG.

[0234] For example, a semiconductor layer including an oxide semiconductor, amorphous silicon, or the like is shown in FIG. The present invention can be applied to the transistors 402t and 403t. Even if a pair of gate electrodes are provided so as to sandwich the region in which the transistor channel is formed, This makes it possible to suppress fluctuations in the characteristics of the transistors and improve reliability.

[0235] For example, a semiconductor layer containing polycrystalline silicon or the like is used as the transistor 402 shown in FIG. t and transistor 403t.

[0236] A structure in which a top-gate transistor is applied to the display portion 401 is shown in FIG. Show.

[0237] For example, a semiconductor layer including polycrystalline silicon or a transferred single crystal silicon film is formed as shown in FIG. C) can be applied to the transistor 402t and the transistor 403t shown in FIG. do.
