ABSTRACT:
A light-emitting device includes a plurality of pixels constituting a screen, each of the plurality of pixels including four subpixels, which are a red subpixel, a green subpixel, a blue subpixel, and a white subpixel. The red subpixel has a light-emitting layer formed of a red-light-emitting material that emits red light and extending along the screen, and a color filter provided above the light-emitting layer to transmit red light. The green subpixel has a light-emitting layer formed of a white-light-emitting material that emits white light and extending along the screen, and a color filter provided above the light-emitting layer to transmit green light. The blue subpixel has a light-emitting layer formed of a blue-light-emitting material that emits blue light and extending along the screen, and a color filter provided above the light-emitting layer to transmit blue light. The white subpixel has a light-emitting layer formed of the white-light-emitting material and extending along the screen.
