Display device
The present invention relates to a display device, which comprises a first polarizing plate and a second polarizing plate; the polarization direction of the first polarizing plate and the polarization direction of the second polarizing plate perpendicular to each other; a liquid crystal layer deposited between the first polarizing plate and the second polarizing plate and configured to display images; a polarization control layer laminated onto the second polarizing plate and configured to control the optical path difference; and a third polarizing plate laminated onto the polarization control layer; the third polarizing plate comprises unpolarized regions arranged in an array. By applying voltage to the polarization control layer, the polarization direction of the light is also changed; in this way, the third polarizing plate can act as a grating or a common light-transmitting plate, and the switch between 2D display mode and 3D display mode can be achieved.
