The width of the black stripe pattern is different depending on a display position with respect to the first direction. The first direction is directed from an upper side of the display to a lower side of the display. ## Claims ### Claim 1 A polarization glasses type stereoscopic image display comprising: a thin film transistor array substrate; a color filter array substrate having a plurality of black matrix patterns formed on a first plane facing the thin film transistor array substrate; a plurality of black stripe patterns that are aligned in a first direction correspondingly to the black matrix patterns on a second plane of the color filter array substrate opposite to the first plane; and a patterned retarder disposed over the second plane of the color filter array substrate, wherein a width of the black stripe pattern is different depending on a display position with respect to the first direction, and wherein the first direction is directed from an upper side of the display to a lower side of the display. ### Claim 2 (depends on 1) The polarization glasses type stereoscopic image display of claim 1, wherein the display is divided into an upper portion, a center portion, and a lower portion along the first direction; and wherein the width of the black stripe patterns corresponding to the upper and lower portions of the display is different from the width of the black stripe patterns corresponding to the center portion of the display. ### Claim 3 (depends on 2) The polarization glasses type stereoscopic image display of claim 2, wherein the width of the black stripe patterns gradually decreases from the center portion of the display toward the upper and lower portions of the display. ### Claim 4 (depends on 1) The polarization glasses type stereoscopic image display of claim 1, wherein the display is divided into a plurality of blocks along the first direction; and wherein the width of the black stripe patterns is varied for every block. ### Claim 5 (depends on 4) The polarization glasses type stereoscopic image, display of claim 4, wherein the width of the black stripe patterns decreases in a stepwise manner from a center block of the plurality of blocks toward the uppermost and lowermost blocks. ### Claim 6 (depends on 5) The polarization glasses type stereoscopic image display of claim 5, wherein each of the blocks comprises a plurality of black stripe patterns, and the black stripe patterns in the same block have the same width. ### Claim 7 (depends on 2) The polarization glasses type stereoscopic image display of claim 2, wherein the width of the black stripe patterns gradually increases from the center portion of the display toward the upper and lower portions of the display. ### Claim 8 (depends on 1) The polarization glasses type stereoscopic image display of claim 1, wherein the display is divided into a center block having a first area, an upper block disposed over the center block and having a second area, and a lower block disposed under the center block and having a third area along the first direction; and wherein the width of the black stripe patterns is uniform at the center block, and gradually varies at the upper and lower blocks. ### Claim 9 (depends on 8) The polarization glasses type stereoscopic image display of claim 8, wherein, at the upper and lower blocks, the width of the black stripe patterns gradually decreases toward the outermost black stripe patterns. ### Claim 10 (depends on 8) The polarization glasses type stereoscopic image display of claim 8, wherein, at the upper and lower blocks, the width of the black stripe patterns gradually increases toward the outermost black stripe patterns. ### Claim 11 (depends on 8) The polarization glasses type stereoscopic image display of claim 8, wherein the first area is larger than the second area and the first area is larger than the third area. ### Claim 12 (depends on 8) The polarization glasses type stereoscopic image display of claim 8, wherein the second area and the third area are identical. ### Claim 13 (depends on 1) The polarization glasses type stereoscopic image display of claim 1, wherein the patterned retarder is attached to a first polarizing plate positioned on the second plane of the color filter array substrate; wherein a rear metal layer is formed between the second plane of the color filter array substrate and the first polarizing plate such that static electricity is discharged; and wherein the black stripe patterns are covered with the rear metal layer on the second plane of the color filter array substrate. ### Claim 14 (depends on 1) The polarization glasses type stereoscopic image display of claim 1, wherein the patterned retarder is attached to a first polarizing plate positioned on the second plane of the color filter array substrate; and wherein the black stripe patterns are positioned between the second plane of the color filter array substrate and the first polarizing plate and come into contact with the first polarizing plate. ### Claim 15 (depends on 1) The polarization glasses type stereoscopic image display of claim 1, wherein the patterned retarder is attached to a first polarizing plate positioned on the second plane of the color filter array substrate; wherein a rear metal layer is formed between the second plane of the color filter array substrate and the first polarizing plate such that static electricity is discharged; and wherein the black stripe patterns are formed between the rear metal layer and the first polarizing plate.
