Abstract: A display apparatus is disclosed that includes a substrate, a display element layer, and a color filter layer. The display element layer is disposed on the substrate and includes first, second, and third display elements. The first, second, and third display elements each emit light having a same peak spectrum. The color filter layer includes a first, second, and third color filters disposed on the first, second, and third display elements, respectively. The first color filter has a transmission spectrum with a first transmittance in a wavelength range of and including 510 nm to 550 nm and a second transmittance in a wavelength range of and including 630 nm to 660 nm. A ratio of the first transmittance to the second transmittance is in a range of and including 1:0.01 to 1:0.3.
