Claim 0:
1. A display apparatus comprising:
a display panel; and
a light supplying unit facing the display panel and configured to emit visible light to the display panel,
wherein the display panel includes a first polarizing plate, a first substrate, a liquid crystal layer, a second substrate, and a second polarizing plate, which are laminated on a facing surface of the light supplying unit with respect to the display panel,
wherein the first substrate has a first electrode and a second electrode formed on a layer different from that of the first electrode,
wherein in a plan view, the second electrode extends in a first direction and includes a plurality of branch electrodes arranged in a second direction orthogonal to the first direction,
wherein a transmission axis of the first polarizing plate and a transmission axis of the second polarizing plate are orthogonal to each other, and any one of the transmission axis of the first polarizing plate and the transmission axis of the second polarizing plate is parallel to an orientation direction of liquid crystal molecules when no voltage is applied to the second electrode,
wherein, when a formation surface of the second electrode is used as a base level and a normal direction of the base level is set to 0 degrees, light having a peak of intensity of light at an angle different from 0 degrees in a visible light region is emitted to the display panel from the light supplying unit,
wherein, when no voltage is applied to the second electrode, the light emitted from the normal direction of 0 degrees when viewed from the base level is not diffracted and is emitted in a direction of 180 degrees when viewed from the base level,
wherein, when voltage is applied to the second electrode, the light emitted from the normal direction of 0 degrees when viewed from the base level is diffracted and is emitted in any direction other than 180 degrees when viewed from the base level, and
wherein the intensity of light emitted in the direction of 180 degrees when voltage is applied to the second electrode when viewed from the base level becomes smaller than the intensity of light emitted in the direction of 180 degrees when no voltage is applied to the second electrode.
