Display device

A display device for displaying a color gamut defined by connecting a first defined color in first chromaticity coordinates, a second defined color in second chromaticity coordinates, and a third defined color in third chromaticity coordinates in a CIExy chromaticity diagram, the display device comprising:

• a display panel in which a plurality of pixels displaying the color gamut are arranged;
• and an illumination device configured to radiate light to the display panel, wherein
• the illumination device includes a green semiconductor laser configured to emit laser light of the second defined color, a blue semiconductor laser configured to emit laser light of the third defined color, and a red semiconductor laser configured to emit laser light of a color in fourth chromaticity coordinates which is different from the first defined color,
• each of the pixels displays a color including the first defined color by mixing the laser light in the fourth chromaticity coordinates and the laser light of the second defined color,
• each of the pixels includes a red pixel to display the laser light of the color in the fourth chromaticity coordinates which is different from the first defined color, a green pixel to display the second defined color, and a blue pixel to display the third defined color, where a first field to display the first defined color and the third defined color and a second field to display the second defined color and the third defined color are displayed in a time divisional manner,
• the red pixel and the green pixel include yellow filters configured to pass the color of the fourth chromaticity coordinates and the laser light of the second defined color, and the blue pixel includes a blue filter configured to pass the third defined color, and
• the illumination device turns on, in the first field, the green semiconductor laser in addition to the red semiconductor laser and the blue semiconductor laser, and each of the pixels mixes the laser light of the second defined color into the laser light of the color in the fourth chromaticity coordinates to match the first defined color.
