摘要： 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.

摘要： A monolithic white light emitting device is provided. An active layer in the monolithic white light emitting device is doped with silicon or rare earth metal that forms a sub-band. The number of active layers included in the monolithic white light emitting device is one or two. When two active layers are included in the monolithic white light emitting device, a cladding layer is interposed between the two active layers. According to this light emission structure, white light can be emitted by a semiconductor, so a phosphor is not necessary. The monolithic white light emitting device is easily manufactured at a low cost and applied to a wide range of fields compared with a conventional white light emitting device that needs a help of a phosphor.
