Abstract: Disclosed are a pixel arrangement structure, a metal mask, and a display device, and in the pixel arrangement structure, each repeating element includes four sub-pixels distributed in two rows by two columns, where the four sub-pixels include two first sub-pixels in different rows and different columns, and one second sub-pixel and one third sub-pixel in different rows and different columns. While an image is being displayed, any one first sub-pixel together with one second sub-pixel adjacent thereto and one third sub-pixel adjacent thereto can constitute a light-emitting pixel, so that the image can be displayed at a high resolution using a physical low resolution through borrowing between the sub-pixels.

Abstract: The present disclosure provides a manufacture method of a mask for evaporation and a mask. The manufacture method of a mask for evaporation includes: providing an open mask the open mask including at least one open region (BB); forming a photoresist layer at least in the at least one open region, at least a portion of a pattern of the photoresist layer in the open region (BB) being identical to a hollow portion pattern of the mask for evaporation; and depositing a material of the mask for evaporation in a region in which the photoresist layer is formed, so as to form the non-hollow portion pattern of the mask for evaporation, in which the non-hollow portion pattern is connected to a side wall of the open region at an edge of the non-hollow portion pattern.
