The area needs of the sub-pixel of three colors be arranged it is identical, or according to a fixed ratio setting.But due to pixel
The technique of definition layer limits, and it is that will appear deviation to cause to make, and pixel defining layer opening 031 can shift.With the inclined of Figure 1A
For shifting, area of the uppermost sub-pixel of triangle inside open region is bigger, but the two of lower section sub-pixels are being opened
Area inside mouth region is smaller, this results in the ratio of the ratio and original design of practical sub-pixel light-emitting zone after deviation not
Together, it will result in display problem in this way, influence display effect.
Present inventor provides a kind of solution as a result,.Please refer to Fig.1 B, Fig. 2 and Fig. 3.Figure 1B is this Shen
The schematic diagram of display panel in one embodiment please after deviation.Fig. 2 is a kind of display panel of embodiment of the application
Schematic diagram；Fig. 3 is the schematic cross-section of AA ' in Fig. 2 embodiments；
The display panel of one embodiment of the application includes：Substrate 10, the multiple luminescent colors being set on substrate 10
Different subpixel 20, the sub-pixel 20 include the identical sub-pixel 21 of at least two luminescent colors, which includes successively
First electrode 211, luminous material layer 212 and second electrode 213；In each sub-pixel 20, each sub-pixel 21 is corresponding
211 mutually insulated of first electrode is arranged；
Sub-pixel definition layer 31, the sub-pixel definition layer 31 include multiple open areas 310, and each sub-pixel 20 is right
It should be set in an open area 310；Sub-pixel definition layer 32, in each open area 310, sub-pixel definition layer 32 surrounds
Corresponding first electrode 211 is arranged.It should be noted that the sub-pixel definition layer between two sub-pixels can be integrated
It can separate, the application does not limit this.Embodiment in Fig. 2 and Fig. 3 is only defined with the sub-pixel between two sub-pixels
For layer 32 is integrated.
At least two sub-pixels are arranged in the open area of a sub- pixel defining layer 31 310 and realize height for the present embodiment
PPI, and solve sub-pixel size and the size of design caused by sub-pixel definition layer deviation not using sub-pixel definition layer 32
Equally, display problem caused by.
It is described in detail with reference to Figure 1B, the sub- picture of three same colors is deposited in being open here with a pixel defining layer
For element, triangle dotted line 31 be pixel defining layer opening, sub-pixel includes the sub-pixel 21 of three same colors, here with
Design these three sub-pixels area it is identical for, group pixel defining layer makes when deviation partially as shown in Figure 1B occurs, by
The practical light-emitting zone of pixel has been determined in sub-pixel definition layer, even if deviation has occurred, and does not interfere with pixel
Practical light-emitting area makes deviation thus eliminating the need sub-pixel definition layer and causes the influence to display effect.
Further, in order to ensure offset that sub-pixel definition layer has enough spaces to give sub-pixel definition layer, secondary picture
What the width of plain definition layer can be arranged is more than 1 μm.
Not only sub-pixel definition layer will appear the deviation of technique, and sub-pixel definition layer equally will appear the deviation of technique.
In one embodiment of the application, sub-pixel definition layer 32 is arranged around first electrode 211, and covers the side of first electrode
Edge.The aperture efficiency sub-pixel of namely sub-pixel definition layer is smaller, these surpluses are for preventing the error of technique from leading to time picture
Plain definition layer position deviation is affected without first electrode, the practical light-emitting area of sub-pixel is completely covered.
Further, if sub-pixel definition layer is too close apart from sub-pixel definition layer, it is possible to cause because of deviation secondary
The practical light-emitting area of pixel impacts.And since the region occupied by sub-pixel definition layer is non-luminous region, if
Sub-pixel definition layer will occupy a large amount of area apart from sub-pixel definition layer is too far so that aperture opening ratio declines.The one of the application
In a embodiment, sub-pixel definition layer covers the part edge of sub-pixel definition layer.Aperture opening ratio and the shadow of deviation can be taken into account simultaneously
It rings.
From the foregoing it will be appreciated that sub-pixel definition layer needs to cover first electrode 211, sub-pixel definition layer 31 needs to cover time picture
Plain definition layer 32, therefore, in one embodiment of the application, sub-pixel definition layer 32 is set to first electrode 211 and sub- picture
Between plain definition layer 31.

A kind of technique in layer deposition is formed.Such as：Inorganic material in the application can be silica, silicon nitride or nitrogen oxidation
Silicon, and formed using chemical vapor deposition (CVD).Due to the very thin e.g. 50nm that inorganic material can be formed, etching
When such as angles tape be 45 °, it is general thick if it is organic layer then waste corner width is 30nm*tan45 °=50nm
Degree is micron level, then the width wasted is also other in the micron-scale.Therefore, identical in craft precision, use nothing
Machine material take physical vapor heavy, chemical vapor deposition or atomic layer deposition can smaller waste sector width, it is effective to be promoted
Aperture opening ratio.
Further, the thickness H of sub-pixel definition layer 32 may be set between 50nm-350nm, meet covering first
Simultaneously, aperture opening ratio is guaranteed the demand of electrode edge.In addition as shown in figure 3, there is provision of son on sub-pixel definition layer 32
Pixel defining layer 31, if sub-pixel definition layer thickness setting it is excessive, may result in this degree definition layer top with time
The segment difference of pixel is larger.And second electrode is typically whole face vapor deposition, entire viewing area is covered, from the rim area of display panel in
Between viewing area current potential is provided.If the excessive second electrode that is likely to result in of segment difference herein does not plan a successor, intermediate secondary picture
Element can not be provided current potential, and display is caused to be failed.Therefore, the present embodiment limits the thickness of sub-pixel definition layer 32 in 50nm-
Between 350nm, ensure to avoid second electrode tomography while aperture opening ratio.
