Definitions

  • 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.
  • 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:
  • An embodiment of the present disclosure provides a display panel, including a first substrate and a second substrate disposed opposite to each other, wherein at least one restriction region is formed by a wiring pattern in a peripheral area of the first substrate, and one or more spacers are provided on the second substrate corresponding to the restriction region, the spacers forming restriction with the wiring pattern in at least one direction parallel to the substrates.
  • the forming restriction in at least one direction parallel to the substrates includes forming restriction in at least two directions.
  • the wiring pattern includes a wiring and/or a mark line pattern, the wiring including at least one of a gate line lead wire, a data line lead wire, a common electrode lead wire, an electrostatic protection ring, and a repair line.
  • the at least one restriction region includes a gap between at least two parallel and/or intersecting wires.
  • the at least one restriction region is formed by a bend portion of a single wire.
  • the spacers are provided at least two different restriction regions, the spacers and the different restriction regions performing restriction in at least two different directions parallel to the substrates.

  • At least a portion of the spacers are different in shape or size depending on different restriction regions.
  • Another embodiment of the present disclosure provides a display device including a display panel according to any one of the above embodiments.
  • the technical solution of the present disclosure can effectively prevent the occurrence of misalignment between the upper and lower substrates of a display panel, thereby avoiding the occurrence of light leakage, color mixing and other undesirable phenomena. Further, by using a restriction region formed by wiring in the peripheral area of the first substrate and spacers provided on the second substrate to form a restriction structure, the solution of the present disclosure is simple in structure and inexpensive.

  • the at least one restriction region 4 may be constituted by a gap between at least two parallel and/or intersecting wires 3 .
  • 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 .
