Preparation and three-dimensional display apparatus of parallax barrier layer-attached substrate and the parallax barrier layer-attached substrate

The present invention is a parallax barrier layer is disposed at a position higher accuracy than the conventional stereoscopic display as high quality conventionally provide a three-dimensional display device or the like and a manufacturing method capable. Three-dimensional display device (100) is disposed on the observer side, a first substrate formed of a transparent material (11), a second substrate (21 arranged so as to face the first substrate (11) ) and a liquid crystal layer (30) and, the parallax barrier layer formed directly on the viewer-side surface of the first substrate disposed between the first substrate (11) and the second substrate (21) (12) with the door. Polarizing plate (40) is formed on the surface of the viewer side substrate parallax barrier layer (12) is formed (10).
