The optical member may include a plurality of directional members. The plurality of directional members may have an optic axis.

Claims (14)

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.
