It is understood that luminescent layer 131 includes several luminescence units, luminescence unit includes several sub-pixels.Picture
Plain confining layers 133, which are used to separate, positions adjacent two sub-pixels.In general, luminescence unit includes three sub-pixels.Specifically,
As shown in Fig. 2, the position of each rectangular broken line frame choosing is corresponding with a sub-pixel.
Preferably, in the present embodiment, protrusion is equipped with below the pixel confining layer 133 between each adjacent two luminescence unit
1111.I.e. protrusion 1111 is uniformly distributed, each luminescence unit of energy effective protection luminescent layer 131.
It is highly preferred that being provided with protrusion 1111 below pixel confining layer 133 between each adjacent two sub-pixel.It is i.e. convex
The distribution in portion 1111 more crypto set, and protrusion 1111 is correspondingly arranged on around each sub-pixel, to preferably disperse
Act on the stress on each sub-pixel.
In the present embodiment, protrusion 1111 is distributed between two neighboring sub-pixel, and between each sub-pixel away from

There is concaveconvex structure, and concaveconvex structure is located at the separate OLED device layer of the flexible layer on flexible layer from OLED device layer 130
130 surface.
Inventor is the study found that in general, PI layers of thinner thickness in flexible substrate, even if the thickness of protrusion 1111 is set
It is set to the thickness equal to PI layers in flexible substrate, the buffer function that protrusion 1111 is played is also weaker.Therefore it is slow in order to preferably realize
Effect is rushed, the thickness of the first flexible layer is greater than the thickness of second flexible layer.
Preferably, in the present embodiment, the height of the protrusion 1111 of concaveconvex structure is 10 μm to 30 μm, can play well
Buffer function.Certainly, in a further embodiment, the height of protrusion 1111 is specifically determined according to the cushion performance of the first flexible layer
Degree.
In the present embodiment, projection section of the depressed area 1113 of concaveconvex structure on OLED device layer 130 falls in OLED device
On the luminescent layer of part layer 130.The edge that i.e. luminescent layer 131 is deviateed in the protrusion 111 of concaveconvex structure is arranged, so that it is guaranteed that luminescent layer
The stress at 131 edge can also be alleviated well.
In addition, in order to obtain better visual effect, the size of the display devices such as mobile phone is got over the development of information technology
Come bigger.But larger-size display device is unfavorable for carrying again.Flexible display panels are because its bent characteristic is by more next
More is applied in display device.
Although inventor is the study found that the use of flexible display panels has portable characteristic to a certain extent.
But when bending to flexible display panels, the bent area of flexible display panels can generate folding s tress.The folding s tress
On the luminescence unit for the bent area that nature can act on flexible display panels, lead to the luminous list of the bent area of flexible display panels
There is a phenomenon where stress to concentrate for member, serious, causes the luminescence unit of the bent area of flexible display panels because of suffered bending
Stress is excessive and impaired, more serious, may cause the phenomenon that display panel bent area can not locally be shown.
When display panel 100 is bent, the depressed area of concaveconvex structure can be alleviated and release action is in display panel 100
Folding s tress on luminescence unit reduces the folding s tress acted on luminescence unit, and then effectively avoids luminescence unit
Because suffered folding s tress is excessive and impaired, to effectively prevent the phenomenon that 100 bent area of display panel can not locally be shown.Therefore
The surface of the separate OLED device layer of flexible substrate is arranged to concaveconvex structure in the application, and the protrusion of concaveconvex structure at least
It, can be with relaxation effect in luminescence unit when the inventive concept that partial pixel confining layers are correspondingly arranged is in flexible display panels
On folding s tress.

The second end face 2116 of part layer 130, the area of first end face 2114 is less than the area of second end face, to increase protrusion 2111
Cushion area, preferably to buffer stress.
More specifically, in the present embodiment, protrusion 2111 is terraced in isosceles along the section in the direction perpendicular to flexible substrate 211
Shape, the i.e. cross-sectional area of protrusion 2111 gradually uniformly become larger from first end face 2114 to second end face 2116.Certainly, other
Embodiment, protrusion can also be in Else Rule or irregular shape along the section in the direction perpendicular to flexible substrate.
As shown in figure 4, the display panel 300 that yet another embodiment of the invention provides, unlike display panel 100,
There are two protrusions 3111 for tool between two neighboring sub-pixel.It is understood that since the application is not to the arrangement of sub-pixel
Improve, if therefore distance between two neighboring sub-pixel it is constant in the case where, increase between two neighboring sub-pixel
Protrusion number, then the cross-sectional area of each protrusion is smaller.
The cross-sectional area of protrusion 3111 is smaller, then protrusion 3111 along the direction perpendicular to flexible substrate 311 flexibility compared with
Greatly, so as to preferably alleviating stress.In the present embodiment, section of the protrusion 3111 along the direction perpendicular to flexible substrate 311
