Abstract
A display apparatus includes first to fourth pixels. The first pixel includes a first light-emitting device and a first layer. The first light-emitting device emits first light toward the first layer. An emission spectrum of the first light has an intensity in a blue-light wavelength range and an intensity in a green-light wavelength range. The first layer contains a color conversion material converting blue and green light into red light. The second pixel includes a second light-emitting device and a second layer. The second layer has a function of transmitting blue light. The third pixel includes a third light-emitting device and a third layer. The third layer has a function of absorbing blue light and transmitting green light. The fourth pixel includes a fourth light-emitting device and a fourth layer. The first to fourth light-emitting device provide the same emission spectrum as each other.
