Non-electric-connecting, the present embodiment does not limit this.
As long as it is understood that from the application similarly design, the part display panel of excision is remained, it will
Part of module in non-display area is arranged in bending part, to realize the narrow frame of display panel, all in the guarantor of the application
It protects in range.
In some optional embodiments, referring to FIG. 10, when the flattening of bending part 20 is to 10 place plane of main part, display
The shape of panel is approximately rectangle.The side that bending part 20 is bent to the back side forms folding edge Z1, and display panel includes at least
At least one end of one section of anti-tear edge 40, anti-tear edge 40 and folding edge Z1 connect, and anti-tear edge 40 is curved section
And it is recessed to main part 10.In order to clearly illustrate the technical solution of the present embodiment, Tu10Zhong, with the flattening of bending part 20 to main body
It is illustrated for state when 10 place plane of portion.
Since bending part 20 is during bending, there is the wind of tearing in the part that bending part 20 and main part 10 connect
Danger, specifically, the phenomenon that both ends of folding edge Z1 are susceptible to tearing.In the present embodiment, at least the one of folding edge Z1
End is provided with anti-tear edge 40, and anti-tear edge 40 is curve shape and is recessed to main part 10, can effectively improve curved
The phenomenon that both ends of flanges Z1 are torn promotes the quality of display panel.
In Figure 10, only by anti-tearing edge edge 40 be circular arc for illustrate, anti-tear edge 40 can be semi arch,
It can be 3/4 circular arc.It is understood that there are when multiple anti-tear edges 40 in display panel, each anti-tear edge 40
Shape can it is identical, can not also be identical.
In some optional embodiments, 1, when the flattening of bending part 20 is to 10 place plane of main part is please referred to Fig.1, display
The shape of panel is approximately rectangle.When the flattening of bending part 20 is to 10 place plane of main part, between bending part 20 and main part 10
With clearance portion 41；Bending part 20 is bent to form folding edge Z1 from main part 10, and bending part 20 includes and folding edge Z1 phases
Adjacent first side C1, clearance portion 41 are adjacent with first side C1.In order to clearly illustrate the technical solution of the present embodiment, Figure 11
In, it is illustrated by taking state when bending part 20 is flattened to 10 place plane of main part as an example.
Bending part 20 during bending, phase mutual friction between bending part 20 and main part 10 and it is easy to wear, can drop
The reliability of low display panel.In the present embodiment, it is provided with clearance portion 41, is made between having between bending part 20 and main part 10
Gap, thus the reliability of display panel can be promoted to avoid the phase mutual friction between bending part 20 and main part 10.Optionally,
The width of clearance portion 41 is d, 0.1mm≤d≤5mm.The width of clearance portion 41 is unsuitable too small, is unfavorable for improving less than 0.1mm curved
Phase mutual friction between folding part 20 and main part 10, the width of clearance portion 41 are not easy excessive, can reduce non-display area BB more than 5mm
Area.
The present invention provides a kind of display devices, including display panel provided by the invention.It is this to please refer to Fig.1 2, Figure 12
A kind of structural schematic diagram for display device that inventive embodiments provide.The display device 1000 that Figure 12 is provided includes that the present invention is above-mentioned
The display panel 1001 that any embodiment provides.Display panel 1001 can be liquid crystal display panel, can also be oled panel,
Electronic Paper, QLED (Quantum Dot Light Emitting Diodes, quantum dot light emitting) display panels or micro
Various types of display panels, the application such as LED (micro- light emitting diode, μ LED) panel do not limit this, specifically optionally
Depending on.
It should also be noted that, Figure 12 embodiments only by taking mobile phone as an example, illustrate display device 1000, it is possible to understand that
, display device provided in an embodiment of the present invention, can be computer, TV, display device for mounting on vehicle etc. other have display work(
The display device of energy, the present invention are not specifically limited this.There is display device provided in an embodiment of the present invention the present invention to implement
The advantageous effect for the display panel that example provides can specifically refer to the various embodiments described above illustrating for display panel, this
Details are not described herein for embodiment.
Display panel provided in an embodiment of the present invention and display device, display panel have viewing area and non-display area, packet
It includes：Underlay substrate, underlay substrate are flexible base board；Display panel includes main part and at least one bending part, main part and curved
Folding part connects；Viewing area is located at main part, and viewing area includes a plurality of grid line and multiple data lines；Main part includes being oppositely arranged
Light-emitting surface and the back side, bending part be bent to the side at the back side；Main part includes circuit structure, and at least one bending part includes drawing
Go out structure, deriving structure is electrically connected with circuit structure.Since display panel remains the part display panel of excision, and will cut
The part display panel removed is set as the bending part that can be bent, can be according to the specific design requirement of display panel, will be non-aobvious
Show that the partial circuit element in area is arranged as deriving structure in bending part, non-display area is allow to have more sufficient space
Arrangement cabling, setting circuit element are conducive to promotion display panel and are opening substrate greatly without increasing the width of non-display area
On typesetting rate, promote economic benefit, and can achieve the purpose that save panel design space, be advantageously implemented display panel
Narrow frame.
