Specific embodiment
The preferred embodiment of the present invention is introduced below with reference to Figure of description, proves that the present invention can be implemented to illustrate,
These embodiments can be of the invention to those of skill in the art's complete description technology contents so that in technology of the invention
Hold more clear and is easy to understand.However the present invention can be emerged from by many various forms of embodiments, the present invention
Protection scope be not limited only to the embodiment mentioned in text.
The present embodiment provides a kind of display device, which includes a display panel.
As seen in figures 3-5, the display panel includes first substrate 1, liquid crystal layer 2, conductive adhesive layer 3, high resistant film layer 4, connects
Ground terminal 5, the second substrate 6 and polaroid 7.
Specifically, first substrate 1, high resistant film layer 4 form a confined space by the bonding of conductive adhesive layer 3 to accommodate liquid crystal
Layer 2.High resistant film layer 4 is set to the upper surface of liquid crystal layer 2 and conductive adhesive layer 3, and the second substrate 6 and polaroid 7 are sequentially arranged in high resistance film
The upper surface of layer 4.
First substrate 1 is array substrate common in the art；The second substrate 6 is color film base common in the art
Plate.Wherein, ground terminal 5 is equipped in first substrate 1, one end of ground terminal 5 is electrically connected with control chip (not shown), described
Control chip is 5 input grounding voltage of ground terminal.
Liquid crystal layer 2 and conductive adhesive layer 3 are set to the upper surface of first substrate 1, wherein conductive adhesive layer 3 is rectangular ring, ring
Around and fitting liquid crystal layer 2, refer to Fig. 5.The width of the rectangular ring is 100~1000um, in order to realize display panel
Ultra-narrow frame and provide conductive adhesive layer 3 viscosity, the width of the rectangular ring be preferably 300um, 450um, 650um,
720um、880um、920um、950um。
In order to improve the leakproofness of display panel, the thickness of the conductive adhesive layer 3 in the present embodiment and the thickness one of liquid crystal layer 2
It causes, improves the display quality of display panel.The viscosity with higher of conductive adhesive layer 3, so that first substrate 1 and high resistant film layer 4 are tight
The phenomenon that thickly fitting together, preventing impact of the liquid crystal to conductive adhesive layer 3 in liquid crystal layer 2, cause degumming, influences display surface
The yield of plate.Wherein, the thickness for the conductive adhesive layer 3 that consistency of thickness mentioned here refers to is identical as the thickness of liquid crystal layer 2 or phase
Seemingly.
