The embodiments of the present invention be only exemplary, and the utility model is not limited to these embodiments.Also need
It is noted that in order to avoid having obscured the utility model because of unnecessary details, illustrate only in the accompanying drawings and basis
The closely related structure of the embodiment of the utility model, and the other details little with the utility model relationship are omitted.
Embodiment 1: Fig. 1 is the sectional view for constituting the liquid crystal display main structure of the utility model, according to Fig. 1,
By first substrate 11, the second substrate 12, the liquid crystal layer 13 being clipped between first substrate and the second substrate, first substrate and liquid crystal
Layer opposite side the first polarizing film 14, the second substrate with the second polarizing film 15 of 13 opposite side of liquid crystal layer, first
The first oriented layer 16 that substrate is coated on the face of liquid crystal layer, second be coated on face of the second substrate 12 close to liquid crystal layer
Oriented layer 17, and the frame-type sealing element 18 filled between first substrate 11 and the second substrate 12 are constituted.It could also say that, this
State's net single-phase electric meter intelligent liquid crystal display of utility model include first substrate 11, the second substrate 12, be clipped in first substrate and
Liquid crystal layer 13, first substrate between the second substrate with the first polarizing film 14 of liquid crystal layer opposite side, in the second substrate
With the second polarizing film 15 of 13 opposite side of liquid crystal layer, the first oriented layer is coated on face of the first substrate close to liquid crystal layer
16, the second oriented layer 17 is coated on face of the second substrate 12 close to liquid crystal layer, and in first substrate 11 and the second substrate 12
Between be filled with frame-type sealing element 18.
