Abstract

A multi-curved liquid crystal display panel includes lower and upper substrates provided with first and second regions and bonded to each other, first and second upper polarizing plates on an upper surface of the upper substrate in the first and second regions, and first and second lower polarizing plates on a lower surface of the lower substrate in the first and second regions. The orientations of absorption axes of the first upper polarizing plate and the second upper polarizing plate are different, the orientations of absorption axes of the first lower polarizing plate and the second lower polarizing plate are different, the orientations of the absorption axes of the first upper polarizing plate and the second lower polarizing plate are equal, and the orientations of the absorption axes of the first lower polarizing plate and the second upper polarizing plate are equal.

First claim

What is claimed is:

1. A multi-curved liquid crystal display panel, comprising:
a substrate assembly including a liquid crystal layer between a lower substrate and an upper substrate, the substrate assembly having at least one first region and at least one second region, alternately repeated;
a lower polarizing plate including a first lower polarizing plate on the first region of the lower substrate, and a second lower polarizing plate on the second region of the lower substrate; and
an upper polarizing plate including a first upper polarizing plate on the first region of the upper substrate, and a second upper polarizing plate on the second region of the upper substrate,
wherein the first region of the substrate assembly, the first lower polarizing plate and the first upper polarizing plate have a cup-shaped (∪-shaped) cross-section,
wherein the second region of the substrate assembly, the second lower polarizing plate and the second upper polarizing plate have a cap-shaped (∩-shaped) cross-section,
wherein an orientation of an absorption axis of the first lower polarizing plate is orthogonal to an orientation of an absorption axis of the first upper polarizing plate and an orientation of an absorption axis of the second lower polarizing plate, and
wherein an orientation of an absorption axis of the second upper polarizing plate is the same as the orientation of the absorption axis of the first lower polarizing plate.

2. The multi-curved liquid crystal display panel according to claim 1 ,
wherein the orientation of the absorption axis of the first upper polarizing plate is equal to the orientation of the absorption axis of the second lower polarizing plate.

3. The multi-curved liquid crystal display panel according to claim 1 , wherein the absorption axis of the first upper polarizing plate is vertical relative to a direction of a boundary between the first and second regions, and
wherein the absorption axis of the first lower polarizing plate is parallel to the direction of the boundary between the first and second regions.

4. The multi-curved liquid crystal display panel according to claim 1 , wherein the upper substrate includes a plurality of color filters and a plurality of black matrices disposed between the color filters, the boundary between the first region and the second region overlapping at least a portion of the black matrix.

5. The multi-curved liquid crystal display panel according to claim 1 , wherein the first region and the second region are alternated at least two times.

6. The multi-curved liquid crystal display panel according to claim 1 , wherein a thickness of the first upper polarizing plate is the same as a thickness of the second lower polarizing plate; and
wherein a thickness of the second upper polarizing plate is the same as a thickness of the first lower polarizing plate.

7. The multi-curved liquid crystal display panel according to claim 1 , wherein the extrema points of the substrate assembly, the lower polarizing plate, and the upper polarizing plate adjacent in a first direction have the same distance from a boundary between the first and second regions in a second direction which is orthogonal to the first direction, and
wherein the first direction is parallel to the direction of the boundary between the first and second regions.
