Abstract:
1. A display device comprising: a light emitting unit including a light source and a light-converting part, the light source generating a blue light, the light-converting part converting a portion of the blue light into red light, another portion of the blue light into green light, and emitting a mixture of a remaining blue light, the red light and the green light from the light-converting party to an exterior of the light emitting unit to be perceived as a white light by an observer, and the remaining blue light having a wavelength in the range of 420 nm to 470 nm; and a display panel including a first substrate, a second substrate and a liquid crystal between the first and second substrates, the display panel receiving the white light including the remaining blue light, at least one of the first and second substrate including a first color filter and a second color filter, the first color filter including a first coloring agent that has a maximum light transmittance in a first wavelength range of about 580 nm to about 750 nm and absorbs about 95% to about 100% of the remaining blue light having wavelengths of about 420 nm to about 470 nm, and the second color filter including a second coloring agent that has a maximum light transmittance in a second wavelength range of about 500 nm to about 550 nm and absorbs about 95% to 100% of the remaining blue light having wavelengths of about 420 nm to about 470 nm.
