Abstract
A display device (100) includes a spontaneous light emission-type display panel (10). The display device includes a plurality of pixels (P). The plurality of pixels each include a plurality of sub pixels including a red sub pixel (R), a green sub pixel (G) and a blue sub pixel (B). The display panel includes a red light emitting element (1r), a green light emitting element (1g), and a blue light emitting element (1b). Red light, green light and blue light respectively emitted by the red light emitting element, the green light emitting element and the blue light emitting element each have a spectrum half width of 10 nm or less. The plurality of sub pixels included in each pixel further include a yellow sub pixel (Ye). The display panel further includes a yellow light emitting element (1y) provided in an area corresponding to the yellow sub pixel. The yellow light emitting element emits yellow light having a dominant wavelength of 550 nm or greater and 600 nm or less.
