Abstract
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.
