Abstract
The present invention discloses an OLED display substrate, an OLED display device, and a mask. The OLED display substrate includes a plurality of pixel units, each of which includes a plurality of sub-pixel units arranged in horizontal direction. Each of the plurality of sub-pixel units includes a display region and a non-display region, wherein the display regions in two adjacent columns of the sub-pixel units are arranged in staggered positions. The technical solutions of the present invention effectively solve the problem of color mixture of electroluminescent layers with different colors occurring during vapor deposition of an electroluminescent material, by arranging the display regions in any two adjacent columns of the sub-pixel units in the OLED display substrate in staggered positions.
