Abstract

The present invention provides an OLED display device and a manufacture method thereof. By locating a thickness of a part of the second insulative layer correspondingly positioned above the bottom layer wiring in the white sub pixel area is larger than a thickness of other part of the second insulative layer in the white sub pixel area, increase a vertical distance from the bottom layer wiring to the first electrode in the white sub pixel area, and thus, the short circuit, the overcurrent between the first electrode and the bottom layer wiring of the white sub pixel area can be prevented. The manufacture method of the OLED display device is simple, easy for operation, and the manufactured OLED display device can prevent the short circuit or the overcurrent between the first electrode and the bottom layer wiring of the white sub pixel area occur and raise the manufacture yield of the OLED display device.
