1. A display apparatus, comprising multiple pixels,each of the multiple pixels comprising an organic light-emitting device comprising a first electrode, a light-emitting layer, and a second electrode,the multiple pixels comprising an optical unit for allowing a part of light emitted from the organic light-emitting device to exit to outside while changing an exiting direction thereof,wherein, in the multiple pixels, an optical distance L1 between a light-emission position of the organic light-emitting device and the first electrode and an optical distance L2 between the light-emission position and the second electrode satisfy Expressions below:


  • 2L1



    1/2π

    =1; and


    L2>

    0, and 2L2



    2/2π

    <

    1,where λ

    is a maximum peak wavelength of a spectrum of light emitted from the organic light-emitting device, φ

    1 is a phase shift occurring when the light emitted at the light-emission position is reflected by the first electrode, and φ

    2 is a phase shift occurring when the light emitted at the light-emission position is reflected by the second electrode.
