The side structure of 202 sides can be Fig. 2 and shown in Fig. 3 parallel with the side of first part 2041 of pixel defining layer,
It can be other structures, because the structure of the first part 2041 of pixel defining layer can stop subsequent organic film to interval
The side structure of 202 inside film forming, second part 2042 towards 202 sides of interval of pixel defining layer is being spaced 202 to subsequent
Internal filming performance does not impact, therefore does not limit the second part 2042 of pixel defining layer towards the side of 202 sides of interval
The structure on side.
Preferably, pixel defining layer second part 2042 exists towards the angle α between the side and anode 203 of anode 203
Between 100~120 degree.If pixel defining layer second part 2042 is towards the angle between the side and anode 203 of anode 203
The angle of α is smaller, for example is equal to 90 degree, and the edge-perpendicular of pixel defining layer second part 2042 is in anode 203, or is less than
90 degree, the top of pixel defining layer second part 2042 can block the lateral section, subsequent to form a film on 204 upper layer of pixel defining layer
The film layers such as the first hole injection layer 205 have the risk in the side edge fracture of pixel defining layer second part 2042；Such as
The angle that pixel defining layer second part 2042 towards the angle α between the side and anode 203 of anode 203 is arranged in fruit is larger,
Make pixel defining layer second part 2042 the side formed a biggish gentle slope, it is subsequent 204 upper layer of pixel defining layer at
The film layers such as the first hole injection layer 205 of film have preferable filming performance, but larger gentle slope can occupy display area, cause
The decline of pixel unit aperture opening ratio.Therefore, side and anode of the setting pixel defining layer second part 2042 towards anode 203
Angle α between 203 is more appropriate between 100~120 degree, can both guarantee that the filming performance of subsequent organic film is good,
It can guarantee higher pixel unit aperture opening ratio again.

Plain definition layer first part mutually disconnects, to solve the problems, such as transverse conductance, improves the display effect of organic light-emitting display device
Fruit.With prior art ratio, the technology difficulty of pixel defining layer is also reduced, in the prior art, pixel defining layer is in pixel list
The thickness of first interval is big, is initially formed pixel defining layer film layer, etches the pixel defining layer film layer then to form inverted trapezoidal
Shape, the requirement to etching technics is very high, and technique controlling difficulty is big.And in the present invention, pixel defining layer is on anode
When layer film forming, the thickness of control pixel defining layer film layer is less than thickness in the prior art, is pushed up according to film forming thickness in anode 201
The thickness in portion direction is greater than the characteristic on the thickness on 201 side wall of anode, and technique is easy to accomplish, pixel defining layer first part
Shape be easier to control.Further, because technique is easy to accomplish, degree of controllability is high, can be formed in functional layer and organic light emission
Continuous structure of the cathode layer on layer upper layer between each pixel unit, avoids the display occurred because cathode signal can not transmit from losing
Effect problem.Furthermore in the prior art to guarantee that the formation of the pixel defining layer of inverted trapezoidal will use negative photo glue material, specifically
, negative photo glue material forms insoluble material after receiving illumination, and the illumination far from substrate side is greater than close to substrate
The illumination of side, therefore inverted trapezoidal structure is formed due to the insoluble material of separate substrate side retains more after developing.And this
Pixel defining layer in utility model embodiment one can be used silica, silicon nitride or silicon oxynitride, keep away because of process stabilizing
Exempt from using negative photoresist, steam and remaining volatile organic matter can be absorbed in processing procedure so as to avoid negative photoresist,
To caused by organic light-emitting display device reliability reduce, reduced lifetime the problem of.
