OLED DISPLAY DEVICE AND MANUFACTURING METHOD THEREFOR

摘要

An OLED display device and a manufacturing method. The thickness of a flat layer (5) in a white sub-pixel area (40) of the OLED display device is set to be greater than the thickness of flat layers (5) in other sub-pixel areas, so that the vertical distance between a bottom line (2) and a first electrode (6) in the white sub-pixel area (40) is increased, the problem that the vertical distance between the bottom line (2) and the first electrode (6) in the white sub-pixel area (40)is excessively small due to the absence of a light filter in the white sub-pixel area (40) is remedied, and a short circuit or overcurrent between the first electrode (6) and the bottom line (2) in the white sub-pixel area (40) can be avoided; and the process yield of the OLED display device is increased.
