Abstract

A display device is disclosed. The display device includes a substrate, a display area on the substrate, the display area including a plurality of subpixels, a pad area on the substrate, the pad area including a pad electrode, a conductive adhesive layer on the pad electrode, and a driver on the conductive adhesive layer, the driver being attached to the pad electrode using the conductive adhesive layer. One surface of the conductive adhesive layer includes one surface of the driver. A vertical distance ranging from a shorter side of one surface of the driver to a shorter side of one surface of the conductive adhesive layer lies substantially in a range between 0.2 mm and 4 mm.

Claims (39)

1. A display device, comprising:

a substrate;

a display area on the substrate, the display area including a plurality of subpixels;

a pad area on the substrate, the pad area including a pad electrode;

an insulating layer having an opening formed around the pad area for exposing the pad electrode;

a conductive adhesive layer on the pad electrode within the opening so that the size of the conductive adhesive layer is limited by the opening; and

a driver on the conductive adhesive layer, the driver being attached to the pad electrode using the conductive adhesive layer,

wherein one surface of the conductive adhesive layer includes one surface of the driver,

a distance ranging from a shorter side of one surface of the driver to a shorter side of one surface of the conductive adhesive layer lies substantially in a range between 0.2 mm and 4 mm, and

the distance is configured to be capable of preventing a moisture-proofing agent coated on the driver from being come off and reducing a number of defective display devices to less than 16% by improving moisture proofing properties.

2. The display device of claim 1 , wherein the driver is a driver integrated circuit.

3. The display device of claim 1 , wherein the conductive adhesive layer is an anisotropic conductive film.

4. The display device of claim 1 , wherein the subpixels include a first electrode, an emitting layer, and a second electrode.

5. The display device of claim 1 , further comprising a thin film transistor including a semiconductor layer, a gate insulating layer, a gate electrode, a source electrode, and a drain electrode on the substrate.

6. A display device, comprising:

a substrate;

a display area on the substrate, the display area including a plurality of subpixels;

a pad area on the substrate, the pad area including a pad electrode;

an insulating layer having an opening formed around the pad area for exposing the pad electrode;

a conductive adhesive layer on the pad electrode within the opening so that the size of the conductive adhesive layer is limited by the opening; and

a driver on the conductive adhesive layer, the driver being attached to the pad electrode using the conductive adhesive layer,

wherein one surface of the conductive adhesive layer includes one surface of the driver,

a distance ranging from a longer side of one surface of the driver to a longer side of one surface of the conductive adhesive layer lies substantially in a range between 0.1 mm and 1 mm, and

the distance is configured to be capable of preventing a moisture-proofing agent coated on the driver from being come off and reducing a number of defective display devices to less than 27% by improving moisture proofing properties.

7. The display device of claim 6 , wherein the driver is a driver integrated circuit.

8. The display device of claim 6 , wherein the conductive adhesive layer is an anisotropic conductive film.

9. The display device of claim 6 , wherein the subpixels include a first electrode, an emitting layer, and a second electrode.

10. The display device of claim 6 , further comprising a thin film transistor including a semiconductor layer, a gate insulating layer, a gate electrode, a source electrode, and a drain electrode on the substrate.

11. A display device, comprising:

a substrate;

a display area on the substrate, the display area including a plurality of subpixels;

a pad area on the substrate, the pad area including a pad electrode;

an insulating layer having an opening formed around the pad area for exposing the pad electrode;

a conductive adhesive layer on the pad electrode within the opening so that the size of the conductive adhesive layer is limited by the opening; and

a driver on the conductive adhesive layer, the driver being attached to the pad electrode using the conductive adhesive layer,

wherein one surface of the conductive adhesive layer includes one surface of the driver,

a distance ranging from a shorter side of one surface of the driver to a shorter side of one surface of the conductive adhesive layer lies substantially in a range between 0.2 mm and 4 mm,

a distance ranging from a longer side of one surface of the driver to a longer side of one surface of the conductive adhesive layer lies substantially in a range between 0.1 mm and 1 mm,

the distances are configured to be capable of preventing a moisture-proofing agent coated on the driver from being come off.
