摘要： A display device includes a light source to generate a beam of a first color. The display device also includes a display panel having at least one pixel including a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel, wherein the second color sub-pixel is configured to generate a beam of the second color by reacting with the beam of the first color, the third color sub-pixel is configured to generate a beam of the third color by reacting with the beam of the first color, and the first color sub-pixel is configured to allow the beam of the first color to pass therethrough. The display device further includes a beam path converter disposed between the light source and the display panel to direct the beam of the first color from the light source toward the display panel.
