Abstract
A display apparatus with a high level of immersion or realistic sensation is provided. The display apparatus includes a display portion capable of full-color display, a communication portion having a wireless communication function, and a wearing portion that can be worn on a head. In an emission spectrum of blue display provided by the display portion at a first luminance, when the intensity of a first emission peak at a wavelength higher than or equal to 400 nm and lower than 500 nm is 1, the intensity of a second emission peak at a wavelength higher than or equal to 500 nm and lower than or equal to 700 nm in the emission spectrum is 0.5 or lower. The first luminance is any value higher than 0 cd/mand lower than 1 cd/m.
