Abstract:
A light-emitting device includes a plurality of pixels constituting a screen, each of the pixels including four subpixels, which are a red subpixel, a green subpixel, a blue subpixel, and a remaining subpixel. The red subpixel has a light-emitting layer made of a white-light-emitting material and extending along the screen, and a color filter provided above the light-emitting layer to transmit red light, the white-light-emitting material emitting two-peak white light having an emission spectrum including a valley between a red peak residing in a wavelength range of red light and a blue peak residing in a wavelength range of blue light. The blue subpixel has a light-emitting layer made of the white-light-emitting material and extending along the screen, and a color filter provided above the light-emitting layer to transmit blue light. The remaining subpixel has a light-emitting layer made of the white-light-emitting material and extending along the screen. The green subpixel has a light-emitting layer made of a green-light-emitting material that emits green light and extending along the screen, and a color filter provided above the light-emitting layer to transmit green light.
