Abstract
The present disclosure provides a top-emitting white organic light emitting diode (OLED) device, a method for manufacturing the same and a display apparatus. The OLED device includes a plurality of pixel units on a substrate, wherein each pixel unit includes a first electrode layer, an organic layer and a second electrode layer arranged subsequently on the substrate from bottom up, and the organic layer in each pixel unit includes a gradually-varied cavity length, and the gradually-varied cavity length corresponds to a range from a wavelength of red light to a wavelength of blue light.
