Seeing shown in Fig. 1 and Fig. 2, this utility model embodiment provides a kind of display base plate, including flexible base board
11 and multiple submounts 12 of being formed on described flexible base board 11, described flexible base board 11 includes flexibility
Basal layer 111 and the inorganic layer 112 being formed in described flexible base layer 111；Wherein, adjacent submounts
Between be provided with cutting zone, the part corresponding with cutting zone of described inorganic layer 112 is removed, formed
First removes region 1121.And after cutting, the corresponding entity flexible display device of each submounts.
So, due to the described first existence removing region 1121, it is possible to avoid cutting described inorganic layer
Make it produce crack when 112, thus do not interfere with the effect of described inorganic layer 112 water proof oxygen barrier, will not lead
The packaging effect causing flexible display device is deteriorated, and can improve the performance of flexible display device.
Wherein, described inorganic layer 112 is generally made by the inorganic material such as silicon oxide or silicon nitride and is formed.Described
The organic material of flexible base layer 111 is selected from polyimides, Merlon, polyacrylate, polyetherimide
The organic materials such as amine, polyether sulfone, polyethylene terephthalate or PEN.
In this utility model embodiment, because the cutting pressure of organic material is the least, easily it is cut, so,
Described first removes region 1121 can be filled by organic material.
Described organic material is selected from: polyimides, Merlon, polyacrylate, Polyetherimide,
The organic materials such as polyether sulfone, polyethylene terephthalate or PEN.
Or, described organic material is selected from: the UV with shock-absorbing capacity solidifies resin or thermosetting resin etc.
Organic material.
In this utility model embodiment, shown in Figure 1, described inorganic layer 112 can be single layer structure, example
As included one layer of inorganic layer formed by silicon oxide or silicon nitride.
