The invention provides a pixel structure and an OLED display panel. Each pixel unit is composed of two sub-pixels arranged in a first direction and having different colors. An adjacent pixel unit of each pixel unit in a second direction comprises two sub-pixels with colors different from those of the two sub-pixels in the pixel unit. When displaying different colors, each pixel unit may use the sub-pixels with different colors in the adjacent pixel unit in the second direction. Thus, the size of the evaporation opening on the evaporation mask can be increased in the case of the same connection bridge size so that the area of the light emitting area of the sub-pixel can be increased, or the size of the connection bridge on the evaporation mask can be increased, and the difficulty of mask production process and the evaporation process can be decreased. In addition, the two adjacent pixel units in the first direction are mirrored symmetrically so that the sub-pixels with the same color in the two adjacent pixel units on the same row can be formed by the same evaporation opening, and the area of the light emitting area of the sub-pixels can be further increased.
