LIQUID CRYSTAL DISPLAY PANEL AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

The liquid crystal display panel includes a liquid crystal display unit, and a backlight unit illuminating the liquid crystal display unit. The backlight unit includes first and second white light-emitting diodes that respectively emit white light, and first and second drive units that respectively supply a current to the first and second white light-emitting diodes. The first and second drive units are respectively configured to be able to adjust supply current to the first and second white light-emitting diodes. Chromaticities of the first and second white light-emitting diodes are of a relationship of being positioned opposite each other across a blackbody locus on an xy chromaticity diagram. The first and second white light-emitting diodes change over time so that, on the xy chromaticity diagram, an intersection point of the blackbody locus and a line that passes through the chromaticities of the first and second white light-emitting diodes becomes constant.
