Abstract: An LCD(Liquid Crystal Display) is provided to realize the excellent color reproducibility and optical efficiency by using an ultraviolet ray emission unit as a light source and by using fluorescent layer for converting ultraviolet ray to visible light. A light source emits ultraviolet ray. A fluorescent layer is formed to convert ultraviolet ray emitted from the light source to the visible light. An ultraviolet LED(Light Emitting Diode) or an ultraviolet lamp is used as the light source. The fluorescent layer is formed at the color filter substrate or at the thin film transistor substrate included in the LCD. A black matrix(210) is formed on the color filter substrate. A common electrode is formed on the black matrix. The fluorescent layer is formed between the substrate and black matrix, or between the black matrix and common electrode, or on the common electrode, and consists of at least one of red, green and blue fluorescent layers.

Abstract: A backlight unit and an LCD(Liquid Crystal Display) module including the same are provided to prevent light leakage phenomenon from being generated between a light source substrate and a construction member, thereby reducing the loss of light efficiency. Plural light emitting diodes(120) generate light and are mounted on a light source substrate(116). The light source substrate encapsulates the surface except for the light emitting surface of the light emitting diode and reflects the light from the light emitting diode. A reflection layer(118) is formed at any one of the front and rear surfaces of the light source substrate. The light incoming surface of a light guide panel(124) is formed to be opposite to the exit surface of the light emitting diode. Both end surfaces of the light source substrate are attached to the light guide panel. An LCD panel(102) implements an image. A light source unit supplies light to the LCD panel and includes plural light emitting diodes.
