Abstract

An electronic apparatus including a display panel including a display region, an antenna layer disposed on the display panel and including a first surface overlapping the display region and a first side surface connected to the first surface, and a circuit board connected to the antenna layer. The circuit board includes a second surface partially facing the first surface of the antenna layer and a second side surface connected to the second surface, and the second side surface faces the first side surface.

First claim

What is claimed is:

1. An electronic apparatus comprising:
a display panel comprising a display region;
an antenna layer disposed on the display panel and comprising:
a base film;
a plurality of antennas disposed on the base film in the display region;
a plurality of antenna pads disposed on the base film, not overlapping the display region; and
a plurality of antenna lines electrically connecting the plurality of antennas respectively to the corresponding plurality of antenna pads; and
a circuit board connected to the antenna layer and comprising:
a base layer;
a conductive layer disposed on the base layer; and
a cover layer disposed on the conductive layer, partially overlapping the conductive layer, and partially facing the display panel,
wherein a surface of the conductive layer not overlapped by cover layer is contact with the plurality of antenna pads, and
wherein a side surface of the cover layer facing a side surface of the base film.

2. The electronic apparatus of claim 1 , wherein:
the side surface of the base film comprises a plurality of first grooves; and
the side surface of the cover layer comprises a plurality of second grooves.

3. The electronic apparatus of claim 2 , wherein each of the plurality of first grooves and the plurality of second grooves comprises a curved surface.

4. The electronic apparatus of claim 2 , wherein the plurality of first grooves and the plurality of second grooves have a polygonal shape.

5. The electronic apparatus of claim 2 , wherein the plurality of first grooves engage with the plurality of second grooves.

6. The electronic apparatus of claim 1 , further comprising a plurality of sensing electrodes disposed on the display panel, wherein the plurality of antennas overlap the plurality of sensing electrodes.

7. The electronic apparatus of claim 1 , further comprising a plurality of sensing electrodes disposed on the display panel, wherein the plurality of antennas are disposed on the same layer as at least a portion of the plurality of sensing electrodes.

8. The electronic apparatus of claim 1 , wherein:
the antenna layer comprises a bent portion which is bent at a curvature; and
the side surface of the base film corresponds to an end of the bent portion.

9. The electronic apparatus of claim 1 , wherein the circuit board is bent so that at least a portion of the circuit board overlaps the display panel.

10. The electronic apparatus of claim 1 , wherein the side surface of the base film is in direct contact with the side surface of the cover layer.

11. The electronic apparatus of claim 1 ,
wherein:
the circuit board includes a stepped portion defined between the side surface of the cover layer and the surface of the conductive layer not overlapped by cover layer; and
the stepped portion faces the base film.
