Belong to electrode layer, for convenience of manufacturing, the material of light shield layer 16 can be identical as the metal electrode layer in substrate layer 11, then can be not
Influence the production that light shield layer 16 is realized in the case where technique.Light shield layer 16 may also be disposed in the substrate of substrate layer 11, such as soft
Property substrate includes PI layers, BL layers of alternatively layered structure, and light shield layer 16 can be formed between two PI layers in substrate manufacture.
For the second encapsulation part 134, wherein it is embedded with light action portion 17, specifically, the inorganic layer of the second encapsulation part 134
Fluted 135 are formed in 131, which is applied not only to be embedded light action portion 17, it can also prevent when forming organic layer 132,
Organic material flows diffusion to the periphery, then influences water oxygen isolation effect and is further formed with the inorganic of multiple grooves 135
Thickness of the layer 131 at special-shaped 142 edge of viewing area is greater than it in the thickness of groove 135, i.e. 135 part of groove will not be formed in side
At edge.
The concretely light screening material of light action portion 17, to reduce light extraction efficiency.Light action portion 17 may be provided at part recess
In 135, the light of the sending of part abnormity viewing area 142 is covered to a certain extent, to weaken the hair of special-shaped viewing area 142
Light efficiency.
It is most dark areas further, since there is no brightness in non-display area, and conventional 241 brightness of viewing area is most bright, therefore can
Light screening material 27 is only filled at the groove 233 near non-display area, as shown in fig. 6, Fig. 6 is the reality of display panel shown in Fig. 2
Apply another structural schematic diagram of example.It can also be on direction of the conventional viewing area 141 towards special-shaped viewing area 142, in multiple grooves 135
The content of light screening material 17 can be gradually increased so that the light emission luminance of special-shaped viewing area 142 gradually weakens, form transition,
Reach better visual effect.
