LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A liquid crystal display is provided to prevent the deterioration of display quality and lifetime of a fluorescent material. CONSTITUTION: A fluorescent material film(300) is formed on a light guide. The fluorescent material film(310) is coated on a base film(320). A coating layer(330) blocks external moisture from the fluorescent material film. An optical sheet is formed on the fluorescent material film. A liquid crystal panel is formed on the optical sheet. The fluorescent material film changes the light of LEDs into white light.
