Abstract

A display device having a minimal overall thickness is achieved by receiving a camera in an accommodation space on at least one among upper and lower substrates. The optical affects caused by reflection of light off the camera or its components can be minimized by a special low reflective film provided in the accommodation space.

Claims

1. A display device comprising:

a lower substrate;

an upper substrate above the lower substrate,

wherein the lower substrate has an accommodation space at a bottom surface thereof in a non-display area, the accommodation space configured to receive at least a portion of a camera therein, and

wherein the upper substrate has a transparent area corresponding to the accommodation space of the lower substrate; and

a low reflective film attached to a bottom surface of the upper substrate in the accommodation space to minimize glittering effects caused by light reflections caused by the camera,

wherein the low reflective film is of a tape-type,

wherein the low reflective film includes a transparent adhesive layer attached to the bottom surface of the upper substrate, a low reflective layer disposed under the transparent adhesive layer, and a protective layer under the low reflective layer to protect the low reflective layer from the camera, and

wherein the protective layer allows the camera to contact therewith.

2. The display device of claim 1, wherein the accommodation space is configured to reduce a thickness of the display device by receiving the camera therein.

3. The display device of claim 1, wherein the accommodation space completely penetrates the lower substrate.

4. The display device of claim 1, wherein

the low reflective layer is configured to minimize glittering;

and

the transparent adhesive layer is configured to allow adhesion with the upper substrate, and is configured to maximize a transmittance ratio with respect to the transparent area above the camera.

5. The display device of claim 4, wherein the transparent adhesive layer is an optically clear adhesive (OCA) that minimizes particles or bubbles between the upper substrate to which the transparent adhesive layer is attached and the low reflective film.

6. The display device of claim 4, wherein the protective layer minimizes the low reflective layer from being damaged due to the camera being in contact with the low reflective layer.

7. A display device comprising:

a lower substrate having a recess in a non-display area;

an upper substrate on the lower substrate;

an anti-reflective film including a transparent adhesive layer attached to the upper substrate, a low reflective layer disposed under the transparent adhesive layer, and a protective layer under the low reflective layer; and

a camera at least partially inserted in the recess at the lower substrate and under the anti-reflective film,

wherein the anti-reflective film is of a tape-type and disposed in the recess, and

wherein the protective layer allows the camera to contact therewith.

8. The display device of claim 7, wherein the recess in the lower substrate is a hole penetrating the lower substrate.

9. The display device of claim 7, wherein the recess at the lower substrate penetrates the lower substrate and is extended to a bottom surface of the upper substrate, and

wherein the upper substrate is connected to the recess in the lower substrate.

10. The display device of claim 9, wherein a width or a diameter of the recess at the lower substrate is equal to or larger than a width or a diameter of the camera.

11. The display device of claim 7, wherein a thickness of the transparent adhesive layer ranges from 10 μ

m to 40 μ

m.

12. The display device of claim 7, wherein the transparent adhesive layer is an optically clear adhesive (OCA).
