Abstract

A display device is provided. The display device includes a substrate, a plurality of self-emissive devices provided at a front surface of the substrate, a molding layer configured to cover at least a portion of the front surface of the substrate and at least a portion of the plurality of self-emissive devices, the molding layer comprising at least one uneven portion, and a polarizing member spaced apart from a front surface of the molding layer so as to not adhere optically with the molding layer.

Claims (18)

1. A display device comprising:

a substrate;

a plurality of self-emissive devices provided at a front surface of the substrate;

a molding layer configured to cover at least a portion of the front surface of the substrate and contacting a light-emitting surface of at least one of the plurality of self-emissive devices, the molding layer comprising at least one uneven portion; and

a polarizing member spaced apart from a front surface of the molding layer so as to not adhere optically with the molding layer.

2. The display device of claim 1 , wherein the at least one uneven portion comprises a plurality of uneven areas arranged irregularly.

3. The display device of claim 1 , further comprising an air layer provided between the molding layer and the polarizing member, and

wherein the at least one uneven portion is formed integrally with the molding layer at a surface of the molding layer which contacts the air layer.

4. The display device of claim 1 , wherein the at least one uneven portion comprises a thin film anti-glare (AG) film.

5. The display device of claim 1 , wherein the at least one uneven portion comprises a thin film optical film formed with a plurality of fine uneven areas.

6. The display device of claim 1 , further comprising a filling layer provided between the plurality of self-emissive devices,

wherein the filling layer comprises a black-based color and is configured to cover side surfaces of the plurality of self-emissive devices.

7. The display device of claim 6 , wherein the filling layer is configured to cover the front surface of the substrate excluding at least one light-emitting surface of the plurality of self-emissive devices.

8. The display device of claim 6 , wherein the plurality of self-emissive devices are electrically and physically coupled to a substrate electrode pad of the substrate through an adhesive layer comprising an anisotropic conductive film (ACF) or a conductive ink comprising fine conductive particles.

9. The display device of claim 6 , wherein the plurality of self-emissive devices are physically coupled to a substrate electrode pad of the substrate through an adhesive layer comprising a non-conductive film (NCF).

10. The display device of claim 1 , wherein the polarizing member comprises:

a glass substrate; and

a circular polarizing layer provided on the glass substrate.
