The color blocking number of plies.
The first situation：As shown in figure 12, the thickness of each layer of color blocking in said first direction is identical, when buffering color blocking
It is in said first direction, described when the color blocking number of plies of stacked structure 93 is less than the color blocking number of plies of the color blocking stacked structure 34
The thickness of buffering color blocking stacked structure 93 is consistently less than the thickness of the color blocking stacked structure 34.
Second situation：With reference to Figure 13, Figure 13 be Fig. 7 along the color membrane substrates of BB ' cutting line include a bent area again
The color blocking thickness of a kind of schematic cross-section, different colours is different, then 34 color blocking includes described slow in the color blocking stacked structure
Rush the color blocking of color blocking stacked structure 93.That is, when the color blocking thickness of different colours is not simultaneously as color blocking stacked structure 34
The color blocking number of plies be greater than the color blocking number of plies of buffering color blocking stacked structure 93, it is evident that the thickness of color blocking stacked structure 34 is slow

The thickness of layer 27 and 28 position of the second barrier layer, the first inorganic encapsulated layer 241 and the second inorganic encapsulated layer 243 is larger,
And organic encapsulation layer 242 ends the side opposite towards the viewing area 11 to color blocking stacked structure 34, leads to the first barrier layer
27 far from the inorganic encapsulated layer for being only left to stack at 11 1 side position of viewing area, firmly along with inorganic layer thickness
Problem causes stress at the position to compare concentration, thus easily cracks or be broken, and is the danger area there are risk of breakage
Domain, therefore color blocking stacked structure 34 is at least covered to the side on relatively described second barrier layer 28 in first barrier layer 27, pole
