Abstract
A stereoscopic image display apparatus employing a front type parallax barrier is provided which can reduce a visible distance. The stereoscopic image display apparatus includes: a 2D image LCD panel having a first substrate in which a rear polarizing film is stacked on the rear surface thereof and a first switching element layer is stacked on the front surface thereof, a second substrate on which a color filter layer is stacked, and a first liquid crystal layer interposed between the first switching element layer and the color filter layer; a parallax barrier having a third substrate in which a front polarizing film is stacked on the front surface thereof and a transparent electrode layer is stacked on the rear surface thereof, a protective film, and a second liquid crystal layer interposed between the transparent electrode layer and the protective film; and an intermediate polarizing film interposed between the protective film of the parallax barrier and the second substrate of the 2D image LCD panel.
