Abstract
A display unit includes a plurality of light-emitting sections and an optical filter. The plurality of light-emitting sections emit color light beams having different colors. The optical filter is disposed on light emission side of the plurality of light-emitting sections, and transmits the color light beams while selectively removing a part of a wavelength band of the color light beams. The optical filter includes the first filter layer and the second filter layer. The first filter layer transmits a first band including a center wavelength out of the wavelength band of each of the color light beams, and removes a second band that is at least a part of a band other than the first band. The second filter layer reduces transmissivity of a third band that is a part of the first band of at least one color light beam out of the color light beams.
