Abstract

A display device may include a display panel that includes a plurality of display elements. The display device may further include a protective member overlapping the display panel. The display device may further include an optical member disposed between the display panel and the protective member and configured to prevent light reflected by the display panel from reaching the protective member. The optical member may include a plurality of directional members. The plurality of directional members may have an optic axis.

First claim

What is claimed is:

1. A display device comprising:
a display panel including a plurality of display elements;
a protective member overlapping the display panel and comprising a first face and a second face, wherein the first face is opposite the second face, wherein the second face is closer to the display panel than the first face, and wherein a material of the first face is identical to a material of the second face;
an alignment layer disposed directly on the second face;
a polarizing layer disposed directly on the alignment layer, the polarizing layer including liquid crystal molecules arranged in a predetermined direction; and
a phase difference layer disposed directly on the polarizing layer, the phase difference layer including reactive mesogens.

2. The display device of claim 1 , further comprising an over coat layer disposed directly on the phase difference layer.

3. The display device of claim 1 , wherein an optic axis of the phase difference layer makes an angle of about 45 degrees with an optic axis of the polarizing layer.

4. The display device of claim 1 , further comprising:
a black matrix disposed between the display panel and the protective member and overlapping a non-display region of the display panel; and
a planarization layer overlapping a display region of the display panel, wherein a portion of the planarization layer is disposed between two portions of the black matrix.

5. The display device of claim 1 , wherein the plurality of display elements includes organic light emitting diodes.

6. The display device of claim 1 , wherein the display device includes a curved portion having a predetermined radius of curvature.

7. The display device of claim 1 , wherein the display device is configured to be folded with respect to an axis.
