Patent ID: 8902384

Claim:
A quantum rod light-emitting display device comprising: a display panel including a first substrate, a second substrate opposite to the first substrate, and a quantum rod layer disposed between the first substrate and the second substrate, wherein quantum rods in the quantum rod layer are arranged in one direction; a backlight unit provided under the display panel and configured to provide light to the display panel; and a short-wavelength pass filter film formed between the first substrate and the backlight unit, and configured to transmit the light from the backlight unit having a first wavelength range and to reflect light from the quantum rod layer having a second wavelength range; a long-wavelength pass filter film disposed between the display panel and the second substrate, and configured to reflect the light from the backlight unit having the first wavelength range and transmit the light from the quantum rod layer having the second wavelength range, wherein the first substrate is disposed closer to the backlight unit than the second substrate, and wherein a wavelength in the first wavelength range is shorter than a wavelength in the second wavelength range.
