An organic electroluminescent display device is provided to reduce a cost and enhance an aperture ratio by enabling a main/sub data drive unit to share one data drive unit. A main display panel(110) has plural main pixels displaying a main image. A sub-display panel(130) has plural sub-pixels displaying a sub-image. A main scan drive unit(210) applies a scanning signal to select the main pixels. A sub-scan drive unit(230) applies a sub-scanning signal to select the sub-pixels. A main/sub data drive unit(300) supplies a main or sub data signal to the main or sub-pixels. The main and sub-pixels arranged in the same row share the same data line and the same power voltage line, respectively.
