Abstract
A double-emission organic light emitting diode (OLED) display device to display images on both sides includes two substrates each having an independently-drivable OLED bonded to each other to prevent breakage due to external pressure and decrease power consumption. The OLED display device includes a first substrate, a first OLED disposed on the first substrate and having at least one first emission layer, a conductive layer disposed on the first OLED, a second OLED disposed on the conductive layer and having at least one second emission layer, and a second substrate disposed on the second OLED. Alternatively, the OLED display device includes a sealant disposed along edges of the first and second substrates to bond the first substrate to the second substrate, and a conductive filler disposed between the first and second substrates.
