Abstract: A display substrate has a display area and an encapsulation area around the display area. The display substrate includes a substrate and a spacer layer. The spacer layer is located on a side of the substrate, and includes a plurality of first columnar spacers located in the encapsulation area and distributed at intervals around the display area, and bottom ends of the plurality of first columnar spacers are fixedly disposed on the substrate. Ends of the plurality of first columnar spacers proximate to the substrate are the bottom ends thereof, and ends of the plurality of first columnar spacers away from the substrate are top ends thereof.

Abstract: A curved surface display panel and a display device are disclosed. The curved surface display panel includes a first substrate a second substrate disposed as opposed to the first substrate, a plurality of spacer formed on the first substrate and a plurality of spacer bases formed on the second substrate in one to one correspondence to the spacers. An end of the spacer distal to the first substrate has a first inclined surface, an end of the spacer base distal to the second substrate has a second inclined surface, and the first inclined surface abuts on the second inclined surface.

Abstract: The invention relates to a light control plate, a dual-view display panel and a display device. The light control plate comprises: a substrate; a grating structure which is arranged above the substrate and has light-transmitting regions and light-blocking regions arranged alternately; and an optical device which is arranged on a boundary of adjacent light-transmitting region and light-blocking region and used for expanding a dual-view visual angle formed by the grating structure.
