Abstract

Embodiments of the invention relate to a stereoscopic image display device using a pattern retarder method, which offers an increased vertical viewing angle and a method for fabricating the same. The stereoscopic image display device comprises: a display panel including data lines, gate lines crossing the data lines, and a plurality of pixels formed in cell areas defined by the crossings of the data lines and the gate lines; and a pattern retarder including a first retarder for passing only left circularly polarized light therethrough and a second retarder for passing only right circularly polarized light therethrough, wherein a plurality of air holes are formed in a first plane of a first substrate of the display panel, and the long axis direction of the air holes is the same as the long axis direction of the first retarder and the second retarder.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2011-0046409 filed May 17, 2011, the entire contents of which are hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0002] Embodiments of the present invention relate to a stereoscopic image display device using a pattern retarder method and a manufacturing method thereof. Background technique [0003] A stereoscopic image display device displays a stereoscopic image by using a stereoscopic technique or an autostereoscopic technique. A stereoscopic technique utilizing binocular disparity between a user's left and right eyes includes a glasses method and a glasses-free method. The glasses method is classified into a pattern retarder method and a shutter glasses method. In the pattern retarder method, a binocular parallax image is displayed on a projector or a direct-view display device by changing a polarization direction, and polarized glasses are u...
