摘要： A display substrate, a manufacturing method and a display device are provided. The display substrate includes: a base substrate and a plurality of sub-pixels; a pixel definition layer arranged on the base substrate and including a plurality of pixel openings, a region where the pixel opening is located being an active light-emitting region of a corresponding sub-pixel; a plurality of post spacers arranged at a side of the pixel definition layer away from the base substrate and configured to support a mask in an evaporation process of the display substrate; and a reflection layer arranged between the post spacer and the base substrate. An orthogonal projection of each post spacer onto the base substrate at least partially overlaps an orthogonal projection of the reflection layer onto the base substrate.

摘要： A touch display device is provided. The touch display device comprises a display panel (5), the display panel (5) has a plurality of pixel units (3), each of the pixel units (3) includes a functional region (31), and a non-functional region (32) is formed between functional regions (31) of adjacent pixel units. The touch display device further comprises a plurality of lines of sensor units (1), and adjacent sensor units in each line of the sensor units are electrically connected with each other by a connection unit. The connection unit includes a connection bridge (21, 22), a projection of at least part of the connection bridge (21, 22) on a light emission surface of the display panel (5) is located in the non-functional region (32) between the functional regions (31) of adjacent pixel units and extends in an extension direction of the non-functional region (32). A shadow dispelling effect of the connection bridge is improved, and display quality of the touch display device is improved.
