Summary:PROBLEM TO BE SOLVED: To provide a display device having high efficiency and high contrast. SOLUTION: The display device includes a substrate, a plurality of pixels formed on the substrate, and a circular polarization member provided on the plurality of pixels, in which each pixel is composed of a plurality of sub-pixels having different luminescent colors and constitutes an organic light emitting element including a pair of electrodes consisting of an anode and a cathode, and a light emitting layer and a charge injection layer formed between the pair of electrodes, and the circular polarization member has a larger transmittance to at least one luminescent color selected from the plural luminescent colors than that to the other luminescent colors. The display device is characterized in that the charge injection layer absorbs the light of the selected luminescent color. COPYRIGHT: (C)2009,JPO&INPIT
