Abstract

A liquid crystal lens panel includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The first substrate includes a first base substrate and a plurality of first electrodes disposed on the first base substrate. The second substrate includes a second base substrate disposed to face the first base substrate, the second substrate further including a plurality of second electrodes disposed on the second base substrate. Each of the first base substrate and the second base substrate are rectilinearly shaped to comprise corresponding first sides and second sides, the plurality of first electrodes and the plurality of second electrodes are inclined with respect to the corresponding first sides or second sides, and the plurality of first electrodes comprise a first inclination angle different from a second inclination angle associated with the plurality of second electrodes.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel comprising a plurality of pixels; and
a lens panel disposed on the display panel configured to refract an incident light from the display panel,
wherein the lens panel refracts the incident light on the basis of a first lens part having a first lens axis, and the first lens part is formed by a first light control signal during a first period,
wherein the lens panel refracts the incident light on the basis of a second lens part having a second lens axis different from the first lens axis, and the second lens part is formed by a second light control signal during a second period.

2. The display apparatus of claim 1 , wherein:
the display panel has a rectangular shape with a first side extending in a first direction and a second side extending in a second direction intersecting with the first direction; and
the first lens axis and the second lens axis are symmetrical with each other with respect to an imaginary line substantially parallel to the first side.

3. The display apparatus of claim 2 , wherein:
the first lens axis is inclined with respect to the imaginary line, and the first lens axis comprises a first inclination angle (A) with respect to the imaginary line;
the second lens axis is inclined with respect to the imaginary line, and the second lens axis comprises a second inclination angle (A) with respect to the imaginary line; and
the second inclination angle satisfies the following:
θ′=θ−180°.

4. The display apparatus of claim 3 , wherein the display panel further comprises:
a light blocking pattern disposed to separate respective pixels,
wherein the first side has a length longer than a length of the second side, each of the pixels has a first width (W 1 ) extending in the first direction, the light blocking pattern has a second width (W 2 ) extending in the first direction, and
wherein the first inclination angle satisfies the following:

wherein an electric field is formed between the first base substrate and the second base substrate by the first light control signal and the second light control signal so that orientation of each of the liquid crystal molecules is varied based on the application of the electric field.

8. The display apparatus of claim 1 , wherein the display panel further comprises:
a first substrate;
an organic light emitting layer disposed on the first substrate; and
a second substrate disposed to cover the organic light emitting layer, the second substrate connected to the first substrate.

9. The display apparatus of claim 1 , wherein the display panel further comprises:
a first substrate;
a second substrate disposed to face the first substrate; and
a liquid crystal layer disposed between the first substrate and the second substrate.

10. A liquid crystal lens panel, comprising:
a first base substrate;
