The organic EL image display device according to the present invention has high brightness at the time of both front observation and oblique observation and little image blurring.

An OLED display device and a method for manufacturing the same are provided. The OLED display device includes an OLED display panel, a driving module and a bonding terminal. The OLED display panel includes a light-emitting surface and a non-light-emitting surface opposite to the light-emitting surface, the bonding terminal is disposed on the non-light-emitting surface, and the driving module is bonded to the bonding terminal. Since the bonding terminal is disposed on the non-light-emitting surface of the OLED display panel and the driving module is bonded to the bonding terminal on the non-light-emitting surface, compared with the prior art, the bonded driving module does not need to be bent again because the bonding terminal is disposed on the non-light-emitting surface of the OLED display panel. The reduction of the bezel width can be maximized and the screen ratio can be increased while reducing the risk of a broken wire.
