A display substrate is disclosed. The display substrate includes a base substrate and a black matrix pattern and a color filter pattern on the base substrate, the black matrix pattern defines one or more display areas of the display substrate and is located on the one or more display A non-display area on the periphery of the area; the color filter pattern includes a plurality of color filter sub-patterns, and each color filter sub-pattern includes a plurality of color filter units; wherein each color filter unit includes a body part, and at least one color filter The unit also includes an anchor portion extending from its body portion, and the dimension of the anchor portion is larger than that of the body portion in a direction perpendicular to the direction in which the body portion extends. Also disclosed are a manufacturing method of the display substrate, a display device and a mask.
Description
technical field [0001] The present disclosure relates to the field of display technology, and in particular to a display substrate, a manufacturing method thereof, a display device and a mask. Background technique [0002] Liquid crystal display devices (LCD) and organic light emitting diode display devices (OLED) are currently mainstream flat panel display devices. In LCDs and some OLEDs, color display is realized through light filtering by a color filter. An LCD generally includes a display substrate and an opposite substrate disposed opposite to each other and a liquid crystal layer therebetween. The display substrate or the opposite substrate includes a color filter to selectively allow transmission of light of a specific wavelength, thereby providing RGB three primary colors and realizing color display. Some OLEDs follow the color display principle of LCD, use OLEDs that emit white light to emit light, and then use color filters to filter to obtain RGB three primary c...
