Abstract: An organic electroluminescent device is provided which includes a colored polarizer to reduce power consumption requirements for desired levels of brightness. The organic electroluminescent device includes a substrate, an anode electrode layer, an organic layer, a cathode electrode layer, and a colored polarizer provided on a surface of the substrate opposite a surface of the substrate on which the anode electrode layer is formed such that the colored polarizer polarizes light incident from the outside. The colored polarizer increases transmission of a given color of light based on the color(s) included in the polarizer to thereby decrease total current required by the organic electroluminescent device.

Abstract: Embodiments of the present invention relate to an organic electroluminescent device using different driving voltages according to sub-pixels. The organic electroluminescent device may include a panel, a driving voltage circuit and a driver. The panel may have a plurality of sub-pixels. The driving voltage circuit may generate a plurality of driving voltages. The driver may drive the sub-pixels by using the generated driving voltages. The organic electroluminescent device may use driving voltages corresponding to sub-pixels, and power consumption may be reduced.
