An OLED display device and a manufacturing method thereof, a display device and a vaporization mask are disclosed. Five sub-pixels () in a pixel unit () of the display device includes at least one red, at least one green and at least one blue sub-pixel. Four of the five sub-pixels () are distributed at four corners and have the same shape and size, the other one is surrounded by the four sub-pixels (), and the four sub-pixels () and the one sub-pixel () are of different colors. Any one sub-pixel () at a corner of the pixel unit () forms a regular pattern with one sub-pixel at a corner in each of other three adjacent pixel units (), and in the regular pattern, all of the sub-pixels are of a same color and each occupies ¼ of the pattern. The display device can reduce the difficulty of manufacturing vaporization openings of a mask and increase the display resolution.
