Abstract
The present application discloses a display substrate including a plurality of pixels arranged in an array of matrix. Each of the plurality of pixels includes several OLED devices emitting light of different color. Each OLED device includes at least a first electrode, a second electrode, and an emitting layer located between the first electrode and the second electrode. At least one layer in either part of the first electrode or the emitting layer forming a microcavity characterized by an optical length. Any two OLED devices emitting light of same color in two adjacent pixels of the plurality of pixels have two microcavities respectively with different optical lengths. At least one OLED device emitting any one colored light in any one pixel of the plurality of pixels has a microcavity with different optical length from other OLED devices emitting light of different color in the same one pixel.
