ABSTRACT:
This invention provides a light emitting device in which each pixel has three sub-pixels for emitting different colors, comprising a signal correction circuit for correcting gradation information of each signal depending on the light emitting index of each sub-pixels, characterized in that; the signal correction circuit has a means to calculate a signal having gradation information according to the following formulae; multiplying the gradation information of the signal input into the three sub-pixels by (1/α):(1/β):(1/γ), when the ratio of the light emitting indexes of the three sub-pixels is α:β:γ.
