The present invention provides a shadow mask, an evaporation device and a related method for manufacturing OLED display panel. The shadow mask has an array of multiple openings. Each opening contains a rectangular first section and a number of second sections at the first section's four corners; and each second section is connected to the first section. By varying the design of the shadow mask, the present invention is able to reduce the ineffective area sizes of the openings, thereby enhancing the aperture ratio of the OLED display panel. |
