Abstract: The embodiments of the present invention provide a mother substrate for display substrates, a display panel and a display device. The mother substrate for display substrates includes a plurality of display substrates and is divided into a display substrate area and a non display substrate area, and at least one film layer of the mother substrate for display substrates has an identical film layer structure in the display substrate area and the non display substrate area. With such arrangement, the arrangement of the at least one film layer is more uniform inside the mother substrate for display substrates, thereby the difference between the stresses applied to the display substrate area and the non display substrate area of the mother substrate for the display substrates by the at least one film layer is reduced significantly.

Abstract: An electronic paper display device according to the disclosure may include an upper substrate provided with a first electrode layer, a lower substrate provided with a second electrode layer, and an electronic ink layer disposed between the first electrode layer and the second electrode layer. Microcapsules are distributed in the electronic ink layer, and at least one kind of quantum dots which are used to display one color are encapsulated within the microcapsules.

Abstract: A method for cutting a substrate of irregular pattern includes: forming a cutting line on the substrate, wherein the closed region enclosed by the cutting line is the irregular pattern that is required; forming a trough line at the cutting line; and applying an external force to the substrate so as to divide the substrate at the trough line. The method can remarkably improve accuracy and efficiency of cutting a substrate of irregular pattern.

Abstract: There are disclosed a pixel structure for a liquid crystal display, an array substrate and the liquid crystal display, for enhancing stability of picture quality of the liquid crystal display. The pixel structure for the liquid crystal display comprises: gate lines (3), a common electrode (2), a thin film transistor, data lines (10) and a pixel electrode (9), wherein the pixel electrode (9) includes a plurality of strip-like portions, and at least one of the strip-like portions of the pixel electrode (9) is placed to overlap a part of a corresponding gate line (3) entirely or in part.

Abstract: Embodiments of the invention provide a color filter substrate, a fabrication method thereof, and a display device. The color filter substrate comprises: a substrate and a color filter film formed on a light incidence side of the substrate. At least one light refraction structure is continuously formed on a light incidence side of the color filter substrate, and each light refraction structure corresponds to a set of field of views (FOVs). The set of FOVs includes a left-eye FOV and a right-eye FOV, light rays from the left-eye FOV pass through a portion of the light refraction structure to which the left-eye FOV corresponds into a left-eye view zone, and light rays from the right-eye FOV pass through the other portion of the light refraction structure to which the right-eye FOV corresponds into a right-eye view zone.
