<P>PROBLEM TO BE SOLVED: To provide a display device that can improve a front-face luminance and prevent deterioration in color purity of light emission in a configuration in which an organic EL element is provided for each of two regions with the same hue obtained by dividing a pixel and a lens is provided on a light emission side of one organic EL element. <P>SOLUTION: A display device includes a pixel having a first region and a second region with the same hue. The first region and the second region each include an organic EL element. The organic EL element includes a first electrode, an organic EL layer, and a second electrode. A lens is provided for the second region on the light emission side of the organic EL element, and the organic EL element in the second region satisfies a particular formula. <P>COPYRIGHT: (C)2013,JPO&INPIT |
