Abstract

A lens panel includes a first substrate, a second substrate and a liquid crystal layer. The first substrate includes a first base substrate, a first electrode formed on the first base substrate, and a first alignment layer formed on the first electrode. The first alignment layer includes a plurality of unit alignment areas forming a lens unit and is aligned to have a first azimuth angle and a plurality of first polarized angles. The first polarized angles vary in the unit alignment area. The second substrate includes a second base substrate, a second electrode formed on the second base substrate, and a second alignment layer aligned to have a second azimuth angle and a second polarized angle. The liquid crystal layer is disposed between the first substrate and the second substrate.

Claims (35)

1. A lens panel comprising:

a first substrate comprising:

a first base substrate,

a first electrode disposed on the first base substrate, and

a first alignment layer disposed on the first electrode, the first alignment layer comprising a plurality of unit alignment areas that form a lens unit;

a second substrate comprising:

a second base substrate,

a second electrode formed on the second base substrate, and

a second alignment layer having a second azimuth angle; and

a liquid crystal layer disposed between the first substrate and the second substrate,

wherein:

the unit alignment areas of the first alignment layer have different polar angles, and the second alignment layer has a uniform polar angle for all of the unit alignment areas such that the liquid crystal layer has different effective azimuth angles in each of the unit alignment areas depending on a polar angle difference between the first and second alignment layers when an electric field is applied thereto; and

widths of the unit alignment areas increase as the unit alignment areas are closer to a center of the corresponding lens unit.

2. The lens panel of claim 1 , wherein the polar angles of the first alignment layer increase in value as positioned closer to a center of the corresponding lens unit.

3. The lens panel of claim 2 , wherein an increase rate of the polar angles of the first alignment layer decreases closer to the center of the corresponding lens unit.

4. The lens panel of claim 2 , wherein the plurality of polar angles of the first alignment layer decrease in value between adjacent unit alignment areas.

5. The lens panel of claim 1 , wherein the first and second alignment layers have different azimuth angles from each other.

6. The lens panel of claim 5 , wherein the difference between the azimuth angles of the first and second alignment layers is about 90°.

7. The lens panel of claim 1 , wherein the first substrate comprises a light absorbing material.

8. The lens panel of claim 1 , further comprising a light absorbing layer disposed on a surface of the second substrate opposite a surface of the second substrate on which the second alignment layer is disposed.

9. A display apparatus comprising:

a panel module to display a 2-dimensional (2D) image or a 3-dimensional (3D) stereoscopic image;

a lens panel comprising:

a first substrate,

a second substrate, and

a liquid crystal layer disposed between the first substrate and the second substrate, the first substrate comprising:

a first alignment layer; and

a first electrode, the first alignment layer comprising a plurality of unit alignment areas, each of the unit alignment areas having a first azimuth angle, the unit alignment areas forming a lens unit,

the second substrate comprising:

a second alignment layer; and

a second electrode, the second alignment layer having a second azimuth angle; and

a light source module disposed along with the panel module to supply light to the panel module,

wherein:

the unit alignment areas of the first alignment layer have different polar angles, and the second alignment layer has a uniform polar angle for all of the unit alignment areas such that the liquid crystal layer has different effective azimuth angles in each of the unit alignment areas depending on a polar angle difference between the first and second alignment layers when an electric field is applied thereto;

widths of the unit alignment areas increase as the unit alignment areas are closer to a center of the corresponding lens unit.
