1. An electro-optical device comprising:

  • a unit circuit includinga first element section that controls a first, electro-optical element to a gradation level corresponding to a level of a data signal, anda second element section that controls a second electro-optical element to a gradation level corresponding to a level of a data signal,the gradation level of the first electro-optical element being lower than the gradation level of the second electro-optical element when data signals having an identical level are applied to the first element section and the second element section; and

    a signal generating circuit that generates data signals having different levels according to a gradation value specified for the unit circuit,wherein when the gradation value is within a first gradation range, the signal generating circuit applies to the first element section a data signal whose level is determined so that the first electro-optical element is controlled to a gradation level corresponding to the gradation value, andwhen the gradation value is within a second gradation range higher than the first gradation range, the signal generating circuit applies to the second element section a data signal whose level is determined so that the second electro-optical element is controlled to a gradation level corresponding to the gradation value.
