Abstract
A white light-emitting device is capable of correcting deviations in chromaticity and includes a plurality of pixels, each of the plurality of pixels includes at least two sub-pixels, and each of the sub-pixels is a white light-emitting element. At least one sub-pixel out of the at least two sub-pixels includes a color filter. The optical characteristic of the color filter is set to correct the deviation of chromaticity of light emitted by the white light-emitting element. The white light-emitting device further controls an emission intensity of each of the white light-emitting elements.
