    摘要： A display apparatus includes a light source emitting light; a light guide plate having a first surface and a second surface, and spreading light emitted from the light source therein to emit light through the first surface; and a local dimming unit configured to pass or scatter light emitted through the second surface of the light guide plate according to a position. The local dimming unit may include: an electro-optical layer configured to which optical properties change according to an electric field; and a plurality of electrodes positioned on the same plane to generate the electric field.

    摘要： The display apparatus includes a display assembly. The display apparatus further includes a mounting device on which the display assembly is mounted and a rotating shaft forming the center of rotation of the display assembly. The rotating shaft is at a fixed location for the mounting device and the display assembly, respectively. The display assembly is switched between a first mode and a second mode rotated from the first mode about a rotating shaft and is changed in the height of the center of the display assembly.
