    Abstract: An array substrate is provided. A respective pixel driving circuit of the array substrate includes a driving transistor, a storage capacitor, and a transistor having a gate electrode connected to a respective second gate line of a plurality of second gate lines, a first electrode connected to a first capacitor electrode of the storage capacitor, and a second electrode connected to a second electrode of a first reset transistor, the transistor being configured to receive a reset signal through the first reset transistor. An active layer of the driving transistor and an active layer of the transistor are spaced apart from each other by at least an insulating layer. The active layer of the driving transistor comprises a first semiconductor material. The active layer of the transistor comprises a second semiconductor material different from the first semiconductor material.

    Abstract: The present disclosure provides a display substrate and a display device. The display substrate includes a plurality of sub-pixels in rows. The sub-pixels in each row includes first sub-pixels, second sub-pixels and third sub-pixels arranged alternately, and two adjacent rows of sub-pixels are arranged in a staggered manner. In every two adjacent rows of sub-pixels, each first sub-pixel in one row of sub-pixels and the second sub-pixel and the third sub-pixel adjacent to the first sub-pixel in another row of sub-pixels form a pixel. White brightness centers of the pixels in a same pixel row are located on a same straight line, and a brightness center of the first sub-pixel is not on a same straight line as the brightness centers of the second sub-pixel and the third sub-pixel located in a same sub-pixel row.

    Abstract: A color filter substrate, a manufacturing method thereof and a display device are provided. The color filter substrate includes: a base substrate; a black matrix on the base substrate, the black matrix including a plurality of openings and a bank surrounding each opening; a color filter layer in each opening; a first planarization layer covering the color filter layer, and the bank protruding relative to the first planarization layer in a direction away from the base substrate; a second planarization layer covering both the first planarization layer and the bank, the second planarization layer including a first surface distal to the base substrate; and a grating layer on the second planarization layer. The first surface of the second planarization layer includes a first portion and a second portion, an orthographic projection of the first portion on the base substrate at least partially overlaps with an orthographic projection of the plurality of openings on the base substrate, an orthographic projection of the second portion on the base substrate at least partially overlaps with an orthographic projection of the bank on the base substrate, and a vertical distance between the first portion and a surface of the base substrate close to the second planarization layer is greater than a vertical distance between the second portion and the surface of the base substrate close to the second planarization layer.
