Patent ID: 8729789

Claim:
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 L 1 between a light-emission position of the organic light-emitting device and the first electrode and an optical distance L 2 between the light-emission position and the second electrode satisfy Expressions below: 2 L 1 /λ+φ 1 /2π=1; and L 2 >0, and 2 L 2 /λ+φ 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.
