Abstract
A photo-luminescent liquid crystal display (PL LCD) includes: a light control unit which includes a liquid crystal (LC) layer modulating the UV light and electrodes driving the LC layer; and a light emitting layer which emits light by the UV light transmitted through the light control unit. The light emitting layer includes inorganic phosphors and semiconductor quantum dots (QDs) having a quantum confinement effect. The PL LCD includes adding QDs having a high quantum efficiency into luminescent substances having lower light utilization efficiency than other colors, for example, red phosphor having very low quantum efficiency to improve the light utilization efficiency, thereby improving the color balance.
