A refering to fig. 1, some embodiments of display according to the present invention, the floor map of display panel 100.Display surface
Plate 100 can be divided into viewing area 100A and non-display area 100B, and wherein non-display area 100B surrounds viewing area 100A, frame glue
(sealant) it 102 is set on non-display area 100B, and surrounds viewing area 100A.Meanwhile B refering to fig. 1, show foundation
Some embodiments of the present invention, along the hatching B-B ' of Figure 1A, the partial cutaway schematic of display panel 100.Such as Figure 1B institute
Show, display panel 100 includes first substrate 101, and the second substrate 103 being arranged relative to first substrate 101, display medium
Layer 105 is folded between first substrate 101 and the second substrate 103, and the frame glue 102 of non-display area 100B is arranged in by display medium
Layer 105 is sealed in first substrate 101 and the sandwiched space of the second substrate 103.
In some embodiments, display panel 100 is, for example, liquid crystal display (liquid crystal display；
LCD), first substrate 101 can be thin film transistor (TFT) (TFT) substrate, and the second substrate 103 can be colored filter (CF) base
Plate, and display dielectric layer 105 can be liquid crystal layer (liquid crystal layer).In some embodiments, frame glue 102
It can be used and apply the non-display area 100B that etamine making process is applied on first substrate 101；In further embodiments, frame glue 102
It can also be used and apply the non-display area 100B that etamine making process is applied in the second substrate 103.
