Description
Technical field
The present invention relates to field of display technology, in particular to a kind of display panel.
Background technique
In current LCD technology, display panel is to be formed by color membrane substrates and array substrate to box, and in
Between filling liquid crystal, the color membrane substrates and the array substrate mainly support box body by setting spacer, to remain certain
Liquid crystal lamellar spacing.However, when existing display panel is extruded, it may occur that following situation: deformation occurs for spacer
And spacer material becomes folding, generates irreversible destruction, is unable to maintain that same liquid crystal lamellar spacing (cell gap), generates push type
Show non-uniform adverse effect, such as: pressing water ripples and jaundice etc. seriously affect visual effect.On the other hand, due to liquid
The thermal contraction of liquid crystal in LCD panel is greater than other components, therefore in the case where box is thick constant, liquid crystal cannot be full of
Entire liquid crystal case assembly and there is bubbles of vacuum, generate display defect.Therefore, the amount of liquid crystal control range of existing display panel
(LC Margin) is smaller, and push type is easy to produce in production and use process and shows air blister defect under uneven and low temperature
Situation.The prior art can only solve the problems, such as this by increasing the quantity of spacer, be unfavorable for manufacturing the display surface of high-res
Plate also greatly increases the cost of technique.In addition, a liner is only arranged in the lower section of master space part in the prior art, to be formed
Segment difference between master space part and secondary spacer, but when master space part is squeezed deformation, master space part is easy to produce sliding, because
This influences the stability of strutting system of two plate bases.
Therefore, it is necessary to one kind is provided, to solve the problems of prior art.
Summary of the invention
In view of this, the present invention provides a kind of display panel, to solve the amount of liquid crystal control range of existing display panel
It is smaller, the problem of push type shows air blister defect under uneven and low temperature is easy to produce in production and use process.
The main purpose of the present invention is to provide a kind of display panel, can make to have between master space part and secondary spacer
There is a segment difference, while master space part being avoided to be squeezed deformation, slided prevented also from master space part, reinforces stability of strutting system, avoid
Push type shows non-uniform phenomenon, effectively improves resistance to pressure, and quantity and volume without increasing spacer improve
The density of sub-pixel is conducive to the display panel for manufacturing high-res.
Secondary objective of the invention is to provide a kind of display panel, can pad in first gasket and described second
A cushion space is provided between piece and the master space part, the master space part can enter the cushion space, so that the master
Spacer when being squeezed will not deformation occurs or bending, and correspond to adjustment liquid crystal lamellar spacing as liquid crystal expands with heat and contract with cold, have
Avoid the occurrence of bubbles of vacuum to effect.
To reach foregoing purpose of the invention, one embodiment of the invention provides a kind of display panel, the display panel packet
It includes:
One first substrate, including a master space part have one end；And
One the second substrate, including one first gasket and one second gasket, first gasket and second gasket against
The two sides of the end symmetric of the master space part.
In one embodiment of this invention, first gasket and second gasket are located at the master space part described
In a projected area in the second substrate.
In one embodiment of this invention, first gasket is arranged in parallel with second gasket, first gasket
And second gasket is tangent with the master space part.
In one embodiment of this invention, the master space part has a bottom, and the bottom connects the first substrate,
The end of the master space part is towards the second substrate.
In one embodiment of this invention, the diameter greater diameter than the end of the bottom.
In one embodiment of this invention, a distance of first gasket and second gasket is less than or equal to described
One diameter of bottom.
In one embodiment of this invention, a height of first gasket and a height of second gasket are less than institute
State a height of master space part.
In one embodiment of this invention, have between first gasket and second gasket and the master space part
One cushion space is used to provide the described master space part into the cushion space.
In one embodiment of this invention, the first substrate further includes a secondary spacer, for the display panel by
The display panel is supported when power.
In one embodiment of this invention, the Radius of the secondary spacer is greater than or equal to the half of the master space part
Diameter.
Compared with prior art, display base plate of the invention is made by the way that two liners are arranged in the two sides of master space part
There is a segment difference between master space part and secondary spacer, while master space part being avoided to be squeezed deformation, prevented also from master space part
Sliding reinforces stability of strutting system, avoids push type from showing non-uniform phenomenon, effectively improve resistance to pressure.On the other hand, described
There is a cushion space, being used to provide the described master space part can between first gasket and second gasket and the master space part
Into the cushion space so that the master space part when being squeezed will not deformation occurs or bending, and with liquid crystal heat expansion
Shrinkage and correspond to adjustment liquid crystal lamellar spacing, be effectively prevented from and bubbles of vacuum occur.In addition, adding the present invention overcomes the prior art
The strong support force of master space part, quantity and volume without increasing spacer improve the density of pixel unit, favorably
In the display panel of manufacture high-res, therefore, display panel of the invention has biggish amount of liquid crystal control range, is conducive to
Manufacture the display panel of accurate narrow frame or Rimless.
