    摘要: The present application provides a display apparatus including: a display panel having a plurality of pixels disposed in a matrix; a first polarizer; a second polarizer; a surface emitting light source; a third polarizer; and a polarization control element whose orientation of a transmission axis changes according to a control signal. A control section outputs a control signal that controls orientation of the transmission axis of the polarization control element so that a polarization axis of transmission light of the polarization control element is oriented in a direction crossing the transmission axis of the first polarizer in a part corresponding to a pixel position of black display and is oriented in a direction parallel to the transmission axis of the first polarizer in a part corresponding to a pixel position of white display.
