More Information
Summary:Disclosed is an organic light emitting display device (100) including an anode (140), a cathode (170), a plurality of organic layers and a partition member (131, 132). The plurality of organic layers is disposed between the anode (140) and the cathode (170), where at least one layer is separated to minimize current leakage into neighboring pixels. The partition member (131, 132)is disposed between the neighboring pixels and configured to separate the plurality of organic layers. The least one separated layer includes a charge generation layer (CGL). Because at least one layer is separated, current leakage into neighboring pixels can be minimized. Accordingly, defects resulting from light leakage and the mixing of colors of light from neighboring pixels may be reduced and display quality is enhanced.
