摘要： A photo-luminescence (PL) liquid crystal display (LCD) is provided. The PL LCD includes a blue backlight, red and green phosphor layers, and blue photo-luminescent nano-dot (ND) layer. The PL LCD improves conventional problems of a narrow viewing angle and orientation. The PL LCD further includes an ultraviolet (UV) filter blocking UV contained in ambient light, thus preventing excitation of light-emitting layer due to external light and degradation in the contrast ratio due to unnecessary light emission.
