Deterioration of display quality due to a difference of leak current in each pixel is suppressed. A pixelG includes a pixel capacitorand a switching elementwhich controls supplying and blocking of voltage with respect to the pixel capacitor, and modulates irradiation light of a first wavelength (530 nm) according to the voltage of the pixel capacitor. A pixelR includes the pixel capacitorand the switching elementthat controls supplying and blocking of voltage with respect to the pixel capacitor, and modulates irradiation light of a second wavelength (620 nm) which is longer than the first wavelength according to the voltage of the pixel capacitor. A capacitance value of the pixel capacitorof the pixelG is larger than a capacitance value of the pixel capacitorof the pixelR.

Electro-optic device and electronic equipment

A display device includes a backlight unit, a light guiding plate which is overlappingly arranged on an optical panel, light emitting elements which are arranged on the side surface of the light guiding plate, and a light source driving unit which drives the light emitting elements. The light source driving unit intermittently turns on all of the light emitting elements when displaying a 3D image on the optical panel. In contrast to this, when displaying a 2D image on the optical panel, each light emitting intensity of the light emitting elements in a part of rows is set to be the same as that in a 3D mode, and each light emitting intensity of the light emitting elements in a part of rows other than that is set to be lower than that in the 3D mode.
