Patent ID: 7557871

Claim:
A 2D/3D switching type liquid crystal display panel, comprising: a display-use liquid crystal panel capable of performing 2D display and 3D display, the display-use liquid crystal panel generating a display image in accordance with image data inputted; a parallax barrier which attains a 3D effect by giving a certain viewing angle to the display image at a time of 3D display; and a switching liquid crystal panel which switches between 2D display and 3D display by enabling or disabling an effect of the parallax barrier, one of (a) the display-use liquid crystal panel and (b) the switching liquid crystal panel being provided closer to a light source than the other, a liquid crystal layer in said one of (a) the display-use liquid crystal panel and (b) the switching liquid crystal panel having a transition point higher than that of a liquid crystal layer in the other, wherein the switching liquid crystal panel, the parallax barrier and the display-use liquid crystal panel are positioned in this order from a light source emitting light that is incident onto the switching liquid crystal panel.
