Abstract:
1. A display device comprising: a display panel including, for every pixel, (i) a first color filter configured to transmit light of two colors out of three primary colors of red, green and blue, and (ii) a second color filter configured to transmit light of two colors out of the three primary colors, one of the colors of light transmittable through the second color filter being different from the two colors of light transmittable through the first color filter, and the display panel configured to display an image based on image signals corresponding respectively to the three primary colors; a light source unit that has a first light emitting unit and a second light emitting unit that are configured such that (i) the first light emitting unit includes either a green light emitting diode that emits green light or a blue light emitting diode that emits blue light and (ii) the second light emitting unit includes either a green light emitting diode that emits green light or a blue light emitting diode that emits blue light, the light emitting diode arranged in the second light emitting unit being of a different color than that arranged in the first light emitting unit, and (iii) either the first light emitting unit or the second light emitting unit further includes a red phosphor arranged together with the green light emitting diode or the blue light emitting diode such that the same light emitting unit emits green or blue light and also emits red light, the light emitting unit that includes the red phosphor being configured to input light of two colors out of the three primary colors as a first input light to the display panel in response to a first light emitting signal, and the other light transmitting unit being configured to input light of one color out of the three primary colors as a second input light to the display panel in response to a second light emitting signal, the second input light being different from the first input light; a light emitting control unit configured to selectively (i) output the first light emitting signal for a first respective one of the light emitting units to emit light, (ii) output the second light emitting signal for a second respective one of the light emitting units to emit light, (iii) output image signals of the two colors corresponding to the first input light, and (iv) output an image signal of the one color corresponding to the second input light, wherein,
