Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application is a National Stage Entry of PCT/CN2016/086712 filed on Jun. 22, 2016, which claims the benefit and priority of Chinese Application No. 201620190763.1 filed on Mar. 14, 2016, the disclosures of which are incorporated by reference herein in their entirety as part of the present application.
  • BACKGROUND
  • The present disclosure relates to the field of display, and more particularly, to a display panel and a display device.
  • The liquid crystal display panel is usually composed of upper substrate and lower substrates and a backlight source, in which the upper and lower substrates are generally a color film substrate and an array substrate. In the case where the alignment is good, the light from the backlight source passes through a filter layer for display of the color film substrate, thereby displaying a screen.
  • The array substrate and the color film substrate of the liquid crystal display panel tend to be displaced in the X direction (i.e., the direction parallel to the array substrate and/or the color film substrate) so that the primary color portions in the color film substrate and the portion of the array substrate for display have displacement deviation, so that when the backlight is irradiated to the array substrate, the liquid crystal display panel is prone to light leakage, color mixing and other undesirable phenomena. This occurs mainly in the following two scenarios:
  • 1) In the manufacture process of the liquid crystal panel, when the sealing rubber between the array substrate and the color film substrate is not cured, and during the processing and transportation process of the liquid crystal panel; and
  • 2) After completion of the manufacture of the liquid crystal panel, extrusion and bending (such as touching) from the Y direction results in local deformation of the glass substrate, and after the deformation is restored it is possible to form a misalignment between the array substrate and the color film substrate.
  • It can be seen that there is a need in the art for a solution that overcomes the displacement between upper and lower substrates of the display panel.

  • Embodiments of the present disclosure will now be described with reference to the accompanying drawings. FIG. 1 shows a cross-sectional view of a display panel according to an embodiment of the present disclosure. FIG. 2 shows a plan view of a display panel according to an embodiment of the present disclosure.

  • For example, the at least one restriction region 4 may be formed by two parallel adjacent wires 3 and a wire 3 perpendicular to the adjacent wires 3 so as to form restriction in both directions toward the adjacent wires 3.
  • FIG. 3 schematically shows a restriction structure in this embodiment.

A spacer 5 is provided on the color film substrate 2 disposed opposite to the array substrate 1, and the spacer 5 corresponds to the position of the restriction region 4 on the array substrate 1 forming a restriction structure when the color film substrate 2 is aligned with the array substrate 1. When the color film substrate 2 and the array substrate 1 are subjected to a lateral displacement tendency due to an external force, the restriction structure may restrict the displacement in both directions, i.e., the direction from the spacer 5 toward the wire 31, and the direction from the spacer 5 toward the wire 32.

As shown in FIG. 4, the spacer group of the spacers 51 and 52 and the restriction regions 41 and 42 formed by the wires 31, 32 and 33 constitute a restriction structure, producing restriction for the displacement of the two substrates in the two directions.

  • According to an exemplary embodiment of the present disclosure, the wire 3 includes at least one peripheral wire of a display panel.
  • According to an exemplary embodiment of the present disclosure, the spacers 5 are provided in at least two different restriction regions 4, the spacers and the different restriction regions performing restriction in at least two different directions parallel to the substrates.

As shown, in the two restriction regions 43, 44 constituted by a plurality of wires 3, the two spacers 53, 54 have different shapes and sizes so that the spacers 53, 54 are better adapted to its corresponding restriction areas, so as to better play the required restriction role.
  • In the above embodiments, the wire 3 may be an existing peripheral wire in the array substrate 1, and the spacers 5 may be existing spacers having a supporting function in the color film substrate 2, and in this case, it is necessary to adjust the positions of at least a portion of the existing spacers so as to be located in the restriction region 4. The spacers 5 may also be spacers provided apart from the existing spacers and dedicated to play the restriction role. The spacers 5 may be one or more, and the restriction regions 4 may also be one or more. In addition, different spacers 5 in different restriction regions 4 may restrict in different directions.
