WHITE LED FOR BACKLIGHT OF FULL-COLOR LIQUID CRYSTAL DISPLAY DEVICE, BACKLIGHT FOR FULL-COLOR LIQUID CRYSTAL DISPLAY DEVICE, AND FULL-COLOR LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed is a white LED for a backlight of a full-color liquid crystal display device, comprising a light emitting element that discharges a primary light, having a light emitting peak within a wavelength region of 360-430nm; and a fluorescent light body layer, including a blue fluorescent light body that is excited by the primary light and emits blue light, a green fluorescent light body that is excited by the primary light and emits green light, and a red fluorescent light body that is excited by the primary light and emits red light having two or more linear light emitting peaks within a wavelength region of 580-740nm. When the liquid crystal display device that is produced employing the white LED represents color reproduction regions of emitted light color of the liquid crystal display device with (u', v') values of an L*u*v* display color chromaticity diagram, the chroma points of each primary color of the light emitting colors of blue, green, and red are respectively within a range of ±0.02, inclusive, of the chroma points of each primary color, blue, green, and red, of ITU-R BT.709.
