Ambient Contrast Ratio of a Liquid Crystal Cell Stacked on a Luminescent Layer

A twisted-nematic liquid crystal cell was placed on a Coumarin 6 layer formed on a transparent plate. Its ambient contrast ratio remained around 10 even at the illuminance of 222 klx while that of a transmissive liquid crystal display operated at 397 cd/m<sup>2</sup> decreased to 5.4.
