Abstract
The invention discloses an OLED device including: a flexible substrate; a first anode and a second anode on the flexible substrate and being spaced from each other to form a channel therebetween; a flexible electrically-conductive assembly in the channel and connecting the first anode with the second anode; a first organic light emitting layer on the first anode and a second organic light emitting layer on the second anode; and a cathode on the first and the second organic light emitting layers. The invention can improve the flexibility of the anode of the OLED device, reduce an actual continuous length of the anode on a bending direction, reduce the probability of crack generation in the process of the OLED device being bent by external force, and therefore can increase bendable and wearable abilities of a flexible OLED display device formed by such OLED device.
