The "horizontal direction" in the above description refers to any direction parallel to the plane on which the first substrate 12 and the second substrate 13 are located.

In the disclosed embodiment, the positioning piece 143 has a first surface facing the second support piece 142, and the second support piece 142 has a second surface facing the positioning piece 143; in the two opposite support structures 14, the distance between the first surfaces of the two positioning members 143 may be greater than or equal to the distance between the second surfaces of the two second support members 142.

For example, when the distance between the first surfaces of the two positioning members 143 is greater than the distance between the second surfaces of the two second supporting members 142 in the two opposite supporting structures 14, a certain gap exists between the second supporting members 142 and the positioning members 143, and when the first substrate 12 and the second substrate 13 are opposite, a larger positioning space is available for the second supporting members 142 to insert, so that the requirement on the alignment accuracy of the second supporting members 142 when inserted into the alignment space can be reduced, and the alignment accuracy of the second supporting members 142 and the first supporting members 141 can be improved; when the distance between the first surfaces of the two positioning members 143 is equal to the distance between the second surfaces of the two second supporting members 142 in the two oppositely arranged supporting structures 14, no gap exists between the second supporting members 142 and the positioning members 143, and after the first substrate 12 and the second substrate 13 are opposite, the second supporting members 142 are in close contact with the positioning members 143, and the second supporting members 142 cannot generate relative movement with the positioning members 143 in the horizontal direction, so that the overall stability of the supporting structure 14 can be improved, and a good display effect of the display panel 1 is ensured.

In the embodiment of the disclosure, the range of values of the lengths of the first connecting piece 15 and the second connecting piece 16 is: the specific values of 15um-30um can be: 15um, 16um, 18um, 20um, 22um, 24um, 26um, 28um, 30um, etc., but are not limited thereto, and may be specific according to practical situations.

In this embodiment of the disclosure, the supporting structure 14 may further include a third supporting member 144, the third supporting member 144 is connected to the second supporting member 142, one end of the third supporting member 144 away from the first supporting member 141 is abutted to the second substrate 13, the third supporting member 144 is opposite to the positioning member 143, when the third supporting member 144 is abutted to the positioning member 143, the contact area can be increased to reduce the contact stress of the positioning member 143 and the third supporting member 144, deformation and displacement of the positioning member 143 and the third supporting member 144 caused by excessive contact stress are avoided, meanwhile, after the third supporting member 144 is abutted to the positioning member 143, the positioning member 143 can form resistance to the displacement of the third supporting member 144, so that the displacement of the third supporting member 144 can be reduced, the extrusion of the third supporting member 144 to the liquid crystal layer 11 is avoided, the liquid crystal deflection is caused, the possibility of light leakage of the display panel 1 is reduced, and the picture display effect of the display panel 1 under the action of external force is ensured.

In the embodiment of the disclosure, the first supporting member 141 may abut against the second supporting member 142, and a redundant space is formed between the third supporting member 144 and the positioning member 143, that is: when the first substrate 12 is opposite to the second substrate 13, the contact between the first support 141 and the second support 142 may be relied on to form a support for the first substrate 12 and the second substrate 13 (as shown in fig. 7, 10 and 11); in addition, in the embodiment of the disclosure, the third supporting member 144 may abut against the positioning member 143, and a redundant space may be formed between the first supporting member 141 and the second supporting member 142, so that when the first substrate 12 is opposite to the second substrate 13, the first substrate 12 and the second substrate 13 may be supported by virtue of the contact between the third supporting member 144 and the positioning member 143 (as shown in fig. 6, 12 and 13).

By abutting the first supporting member 141 against the second supporting member 142 and forming a redundant space between the third supporting member 144 and the positioning member 143, or by abutting the third supporting member 144 against the positioning member 143 and forming a redundant space between the first supporting member 141 and the second supporting member 142, the material for manufacturing the supporting structure 14 can be reduced while ensuring the supporting property of the supporting structure 14 on the first substrate 12 and the second substrate 13, and further the manufacturing cost of the supporting structure 14 can be reduced.

It should be noted that, the side of the second supporting member 142 away from the second substrate 13 should have a certain width, so as to avoid the situation that the supporting structure 14 is easy to deform and displace due to the too small contact surface when the second supporting member 142 is abutted against the first supporting member 141 and the too large contact stress between the second supporting member 142 and the first supporting member 141, thereby ensuring the uniformity of the overall thickness of the display panel 1 and good image display effect.

The width D1 of the second support 142 on the side far from the second substrate 13 is set in the range: the specific values of 5um-8um can be: 5um, 5.5um, 6um, 6.5um, 7um, 7.5um, 8um, etc., but is not limited thereto, and may be specific according to practical situations.

Defining the width D2 of the gap between the first surface and the second surface of the same supporting structure 14, it should be noted that, as the width D1 of the side of the second supporting member 142 away from the second substrate 13 changes, the width D2 of the gap may be correspondingly adjusted, and specifically, the range of values of D2 may be as follows: 0.ltoreq.D2.ltoreq.0.5XD1, i.e.D2 is 0 or more and D2 is 0.5 times or less D1. When d2=0, there is no gap between the positioning member 143 and the second supporting member 142, so that the displacement of the second supporting member 142 can be limited, and the stability of the display panel 1 is improved; when 0< D2.ltoreq.0.5XD1, that is: when D2 is greater than 0 and D2 is less than or equal to 0.5 times of D1, a gap exists between the positioning member 143 and the second supporting member 142, and when the first substrate 12 is opposite to the second substrate 13, a larger positioning space is available for the second supporting member 142 to be inserted, so that the requirement on alignment accuracy when the second supporting member 142 is inserted into the alignment space can be reduced, the accuracy of alignment between the second supporting member 142 and the first supporting member 141 is improved, meanwhile, the displacement range of the second supporting member 142 relative to the first supporting member 141 can be limited, extrusion of the liquid crystal layer 11 caused by overlarge displacement range of the second supporting member 142 can be avoided, and further, the picture display effect of the display panel 1 can be ensured.

In the embodiment of the disclosure, while the first supporting member 141 is abutted to the second supporting member 142, the third supporting member 144 may also be abutted to the positioning member 143, so as to increase the contact surface, reduce the contact stress of the supporting structure 14, and avoid the displacement and deformation of the supporting structure 14 beyond the limit caused by the overlarge contact stress, so as to avoid the extrusion of the supporting structure 14 on the liquid crystal layer 11 and the deflection of the liquid crystal, thereby reducing the possibility of light leakage of the display panel 1 due to the external force, and at the same time, enhance the supporting force of the supporting structure 14 between the first substrate 12 and the second substrate 13, so as to improve the overall stability of the display panel 1; at this time, the movable range of the positioning member 143 on the third supporting member 144 may be larger than the movable range of the second supporting member 142 on the first supporting member 141, and when the supporting structure 14 is displaced in the horizontal direction, the second supporting member 142 is prevented from being separated from the positioning space, so that the possibility that the supporting structure 14 presses the liquid crystal layer 11 and affects the liquid crystal deflection angle is reduced, and the image display effect of the display panel 1 under the action of external force is ensured.

In the embodiment of the disclosure, one of the first substrate 12 and the second substrate 13 is an array substrate, the other is a color film substrate, and the material hardness of the positioning member 143 is greater than the material hardness of the second supporting member 142.

Taking the first substrate 12 as an array substrate and the second substrate 13 as a color film substrate as an example, the positioning piece 143 and the first supporting piece 141 are located on the array substrate, and the second supporting piece 142 is located on the color film substrate, when the display panel 1 is subjected to an external force, the second supporting piece 142 may topple towards the direction of the liquid crystal layer 11, and meanwhile, the positioning piece 143 may deform and displace under the action of the external force, so as to avoid the situation that the positioning effect on the second supporting piece 142 cannot be achieved after the positioning piece 143 deforms and displaces, in the embodiment of the disclosure, the positioning piece 143 may be made of a material with a hardness greater than that of the second supporting piece 142, so that when the second supporting piece 142 is deformed and displaced due to the fact that the hardness of the positioning piece 143 is greater, the positioning piece 143 may not deform and displace or the deformation and displacement are small, so that the positioning effect of the positioning piece 143 on the second supporting piece 142 may be continuously ensured, the second supporting piece 142 is prevented from being separated from the positioning space and from forming extrusion on the liquid crystal layer 11, and further, the angular deflection of the liquid crystal is caused, and the picture display effect of the display panel 1 is ensured.

Specifically, the material for manufacturing the supporting structure 14 may be a resin material, which has a characteristic of high hardness, so that the supporting property of the supporting structure 14 to the first substrate 12 and the second substrate 13 can be ensured, meanwhile, the resin material also has a certain elasticity, under the action of external force, even if the supporting structure 14 can generate a certain deformation and displacement, when the action of external force disappears, the supporting structure 14 can return to the original supporting state again, so that the uniformity of the thickness of the display panel 1 and the good display effect of the display panel 1 are ensured, in addition, the resin material is a transparent material, and light can enter the liquid crystal layer 11 through the resin, so that the blocking of the supporting structure 14 to the light can be reduced, and the utilization rate of the light is improved.

It should be noted that, in the embodiment of the disclosure, the first supporting member 141 and the positioning member 143 may be formed simultaneously by an integration process, and by adopting the integration process, the manufacturing process of the supporting structure 14 may be simplified, so that the manufacturing cost of the display panel 1 may be reduced, and the formed first supporting member 141 and positioning member 143 may be connected to each other, so that the overall stability of the supporting structure 14 may be enhanced.

In the embodiment of the disclosure, the second supporting member 142 and the third supporting member 144 may be formed simultaneously by an integrated process, and by adopting the integrated process, the manufacturing process of the supporting structure 14 may be simplified, so that the manufacturing cost of the display panel 1 may be reduced, and the formed second supporting member 142 and third supporting member 144 may be connected to each other, so as to enhance the overall stability of the supporting structure 14.

It is further noted that the positioning member 143 and the second supporting member 142 are mutually limited, that is: the positioning piece 143 is limiting the displacement of the second supporting piece 142, so that the second supporting piece 142 can limit the displacement of the positioning piece 143 while avoiding the extrusion of the second supporting piece 142 to the liquid crystal layer 11, and the extrusion of the positioning piece 143 to the liquid crystal layer 11 is avoided, thereby reducing the light leakage possibility of the display panel 1 and ensuring the picture display effect of the display panel 1.
