Abstract
A stereoscopic image display includes a display panel including subpixels, a polarizing plate attached to a display surface of the display panel, a patterned retarder film attached to one surface of the polarizing plate, and a pattern groove including an air layer which is formed on one surface of an upper substrate of the display panel contacting the polarizing plate at a location corresponding to a boundary between the subpixels. The pattern groove includes a plurality of peaks and a plurality of valleys and forms a triangular cross section along with a portion of the upper substrate contacting the polarizing plate, thereby providing the air layer.
