Abstract: The present disclosure is directed to a liquid crystal display device including a display panel having a red pixel, a green pixel, and a blue pixel; and a backlight unit configured to emit light to the display panel. The backlight unit includes a light source which outputs a first color light; a color conversion layer configured to convert the first color light into a second color light such that red light and green light are spatially separated; and an optical sheet which diffuses or condenses the second color light.

Abstract: An organic light emitting diode (OLED) display device includes an OLED with a plurality of sub-pixels. A first portion of light-absorption filter layer is between the OLED and an emission surface at locations corresponding to selected sub-pixel locations. The first portion of light-absorption filter layer includes a first light-absorption dye and a second light-absorption dye such that the first portion has a light transmittance curve that has a first valley between 470 nm and 550 nm and has a second valley between 570 nm and 620 nm. At the selected sub-pixel locations, there is a color filter between the OLED and the light-absorption filter.
