[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0184114 filed on December 22, 2015, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present disclosure relates to an organic light emitting display device, in particular to an organic light emitting display device capable of displaying high-resolution images with reduced sub-pixel size. Background technique [0004] An organic light emitting display device, which is a self-luminous display device, does not require a separate light source like a liquid crystal display device, and thus is manufactured to be lightweight and thin. In addition, organic light emitting display devices are advantageous not only in low power consumption but also in fast response speed, wide viewing angle, and excellent contrast due to their low-voltage driving. For these reasons, organic light emitting display devic...
