## Abstract

A polarization glasses type stereoscopic image display displaying a stereoscopic image on a display surface includes 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 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. The overall vertical pitch of the patterned retarder is less than the overall vertical pitch of a pixel array formed on the display surface.

## Claims

### Claim 1

A polarization glasses type stereoscopic image display displaying a stereoscopic image on a display surface comprising:
a thin film transistor array substrate;
a color filter array substrate having a plurality of black matrix patterns on a first plane facing the thin film transistor array substrate;
a plurality of black stripe patterns that are aligned correspondingly to the black matrix patterns on a second plane of the color filter array substrate facing the first plane; and
a patterned retarder disposed over the second plane of the color filter array substrate,
wherein the vertical pitch of the patterned retarder is less than the vertical pitch of a pixel array formed on the display surface.

### Claim 2 (depends on 1)

The polarization glasses type stereoscopic image display of claim 1, wherein the display surface is divided into an upper portion, a center portion, and a lower portion along a first direction from the top to the bottom of the display surface,
wherein the black stripe pattern and the black matrix pattern corresponding to each other overlap each other at a viewing position in the center portion of the display surface, and
wherein the black stripe pattern and the black matrix pattern corresponding to each other partially overlap each other in the upper and lower portions of the display surface and are obliquely aligned at the viewing position.

### Claim 3 (depends on 2)

The polarization glasses type stereoscopic image display of claim 2, wherein an overlap width between the black stripe pattern and the black matrix pattern corresponding to each other in the center portion of the display surface is greater than an overlap width between the black stripe pattern and the black matrix pattern in the upper and lower portions of the display surface, and
wherein the overlap width is vertical to the display panel.

### Claim 4 (depends on 3)

The polarization glasses type stereoscopic image display of claim 3, wherein a width of each of the black stripe patterns gradually decreases as it goes from the center portion of the display surface to the upper and lower portions of the display surface.

### Claim 5 (depends on 3)

The polarization glasses type stereoscopic image display of claim 3, wherein each of the upper portion, the center portion, and the lower portion of the display surface is divided into a plurality of blocks along the first direction,
wherein the width of the black stripe patterns is varied every block.

### Claim 6 (depends on 5)

The polarization glasses type stereoscopic image display of claim 5, wherein the width of the black stripe patterns decreases in a stepwise manner from the center block of the display surface toward the uppermost and lowermost blocks.

### Claim 7 (depends on 5)

The polarization glasses type stereoscopic image display of claim 5, wherein each of the blocks includes a plurality of black stripe patterns, and the black stripe patterns belonging to the same block have the same width.

### Claim 8 (depends on 3)

The polarization glasses type stereoscopic image display of claim 3, wherein a width of the black stripe patterns gradually increases from the center portion of the display surface toward the upper and lower portions of the display surface.

### Claim 9 (depends on 3)

The polarization glasses type stereoscopic image display of claim 3, wherein the center portion of the display panel is selected as a center block having a first area, the upper portion of the display panel is selected as an upper block which is disposed over the center block and has a second area, and the lower portion of the display panel is selected as a lower block, which is disposed under the center block and has a third area,
wherein the width of the black stripe patterns is uniform at the center block and gradually varies at the upper and lower blocks.

### Claim 10 (depends on 9)

The polarization glasses type stereoscopic image display of claim 9, wherein, at each of the upper and lower blocks, the width of the black stripe patterns gradually decreases as it approaches the outermost black stripe pattern.

### Claim 11 (depends on 9)

The polarization glasses type stereoscopic image display of claim 9, wherein, at each of the upper and lower blocks, the width of the black stripe patterns gradually increases as it approaches the outermost black stripe pattern.

### Claim 12 (depends on 9)

The polarization glasses type stereoscopic image display of claim 9, wherein a size of the first area is greater than sizes of the second area and the third area.

### Claim 13 (depends on 9)

The polarization glasses type stereoscopic image display of claim 9, wherein a size of the second area is substantially equal to a size of the third area.
