    摘要: Provided is a photo-luminescence (PL) LCD including: electrodes that are disposed on bottom and top surfaces of front and rear substrate and create an electric field in liquid crystals (LCs); a nano-dot (ND) PL layer that is disposed on the bottom surface of the front substrate and emits light when irradiated with ultraviolet (UV) light, and a UV backlight unit that is located behind the rear substrate and supplying UV light to the ND PL layer. The UV backlight unit is excited by blue UV light having a wavelength range of 360 to 460 nm to emit light. The PD LCD having the above-mentioned structure suppresses absorption of UV light by LC and degradation of the LC while providing high light efficiency.
