Embodiment 1
The structural schematic diagram of the display panel P provided as shown in Figure 1 for the embodiment of the present invention 1 a kind of, the display of embodiment 1
Panel P includes first substrate 1, the second substrate 2 being oppositely arranged with first substrate 1, first substrate 1 towards the second substrate 2
It is installed with the first spacer material 4 on inner wall, is installed on the inner wall towards first substrate 1 of the second substrate 2 and the first dottle pin
Object 4 is correspondingly arranged and the second spacer material 5 of phase sliding contact, and the first spacer material 4 has the nesting of the second spacer material of nested parts 5
Space 40.
Both " fixed " expressions described herein are arranged relatively fixedly, for example, it may be directly fixed setting/company
It connects, the mode indirectly that is also possible to realizes the relatively fixed of the two.
" the nested space 40 that the first spacer material 4 has the second spacer material of nested parts 5 " described above refers to the first dottle pin
Object 4 has the nested space for covering/accommodating the second spacer material 5, so that the second spacer material 5 of limitation is relative to the first spacer material 4
Relative motion, specifically, when between first substrate 4 and the second substrate 5 occur relative displacement when, the second spacer material 5 relative to
The sliding of first spacer material 4 is limited in nested 40 limited range of space.
The display panel P that Fig. 1 show embodiment 1 is in the structural schematic diagram of first state (original state), shown in Fig. 2
It is in the second state for the display panel P of embodiment 1 (display panel is pressed, and the shape of opposite sliding occurs between two substrates
State) structural schematic diagram.When operator presses display panel P, slight Curved occurs for first substrate 1 and the second substrate 2
Become, so that relative displacement occurs between first substrate 1 and the second substrate 2, the second spacer material 5 is slided relative to the first spacer material 4,
I.e. from state shown in state change to Fig. 2 shown in Fig. 1, the opposite sliding of the second spacer material 5 is limited in nested space 40 and is limited
In fixed range；When press release (hand of operator leaves display panel P) when, display panel P from replying state shown in Fig. 2 to
State shown in Fig. 1.
Display panel P using the above structure is matched by the way that two nestings are arranged between first substrate 1 and the second substrate 2
The spacer material of conjunction, limits the relative shift between two substrates, on the one hand prevent from occurring between two substrates it is excessive, cannot
The opposite sliding resetted；On the other hand, be conducive to two substrates substrate of fast quick-recovery, especially two after relative displacement occurs
Between liquid crystal molecule can return to original state more quickly, prevent light from revealing；In another aspect, between two spacer materials
Opposite sliding has buffered the opposite sliding between two substrates, and in a certain range by relative shift control, even if two
A display panel is frequently pressed, and two spacer materials will not scratch alignment film, avoids permanent light leakage.
In this example it is shown that panel P is liquid crystal display panel.In the present embodiment, first substrate 1 is color film base
Plate, the second substrate 2 are array substrate (also known as TFT substrate)；(do not show between first substrate 1 and the second substrate 2 filled with liquid crystal layer
Out).In another alternate embodiment of the invention, first substrate 1 be array substrate, the second substrate 2 be color membrane substrates, the two it
Between filling liquid crystal layer.
As illustrated in fig. 1 and 2, the first spacer material 4 and the second spacer material 5 are collectively formed to first substrate 1 and the second substrate 2
Support, so that there are gaps between first substrate 1 and the second substrate 2.

The central symmetry overlapping of axles of the two substantially overlap.
As illustrated in fig. 1 and 2, in the present embodiment, if the radius of the first sliding contact surface 41 is defined as R1, the second sliding
The radius of contact surface 51 is defined as R2, then the maximum relative displacement amount between two spacer materials is the value that R1 subtracts R2.
Optionally, using the plane of the relative displacement between first substrate 1 and the second substrate 2 as benchmark plane, in the benchmark
In plane, distance (the first sliding contact surface i.e. in the present embodiment of the central symmetry axis X of the first sliding contact surface 41 to edge
41 radius R1) it is 10~15um, such as can be 11um, 12um, 13um and 14um；The center pair of second sliding contact surface 51
The distance at axis X to edge is referred to as 2~10um, such as can be 3um, 4um, 5um, 6um, 7um, 8um and 9um；To by two
Maximum relative displacement amount between spacer material controls within 13um, can be more effectively prevented between two substrates and occur
Amount, irreducible opposite sliding.
