Abstract

According to one embodiment, a display device includes a substrate, a display area displaying an image, a surrounding area surrounding the display area, a display element arranged above the substrate, a first sealing layer formed of an inorganic material and covering the display element, a resin layer arranged on the first sealing layer, a second sealing layer formed of an inorganic material and covering the resin layer, a conductive pad arranged in the surrounding area, and a polarizer arranged above the second sealing layer. At least one of an end portion of the first sealing layer and an end portion of the second sealing layer is located closer to the pad than an end portion of the polarizer is.

Claims (39)

1 . A display device, comprising:

a substrate;

a display area displaying an image;

a surrounding area surrounding the display area;

a display element arranged above the substrate;

a first sealing layer formed of an inorganic material and covering the display element;

a resin layer arranged on the first sealing layer;

a second sealing layer formed of an inorganic material and covering the resin layer;

a conductive terminal arranged in the surrounding area; and

a polarizer arranged above the second sealing layer, wherein

at least one of an end portion of the first sealing layer and an end portion of the second sealing layer is located closer to the terminal than an end portion of the polarizer is.

2 . The display device of claim 1 , wherein

each of the end portion of the first sealing layer and the end portion of the second sealing layer is located closer to the terminal than the end portion of the polarizer is.

3 . The display device of claim 2 , wherein

the end portion of the first sealing layer overlaps with the end portion of the second sealing layer.

4 . The display device of claim 1 , further comprising:

a protrusion surrounding the display area, wherein

the end portion of the polarizer is arranged directly above the protrusion, and

each of the first sealing layer and the second sealing layer overlaps with the protrusion in plan view.

5 . The display device of claim 4 , wherein the protrusion includes a part located between the display area and the terminal, and

at least one of the first sealing layer and the second sealing layer covers the part of the protrusion.

6 . The display device of claim 1 , further comprising:

an insulating layer formed of an organic material, having an aperture overlapping with the terminal, and arranged in the surrounding area, wherein

at least one of the first sealing layer and the second sealing layer is arranged on the insulating layer.

7 . The display device of claim 6 , wherein at least one of the end portion of the first sealing layer and the end portion of the second sealing layer is located between the end portion of the polarizer and the aperture.

8 . The display device of claim 1 , further comprising:

a moisture-proof member in contact with the end portion of the polarizer and an upper surface of at least one of the first sealing layer and the second sealing layer.

9 . The display device of claim 8 , wherein

the moisture-proof member overlaps with at least one of the first sealing layer and the second sealing layer.

10 . The display device of claim 8 , further comprising:

a flexible substrate connected with the terminal, wherein

the moisture-proof member covers an end portion of the flexible substrate.

11 . The display device of claim 1 , further comprising:

a protrusion located between the display area and the terminal and overlapping with the end portion of the polarizer in plan view;

an insulating layer formed of an organic material, including an aperture overlapping with the terminal, and arranged in the surrounding area; and

a moisture-proof member in contact with the end portion of the polarizer and located above the insulating layer, wherein

the protrusion includes a part of the insulating layer,

each of the first sealing layer and the second sealing layer covers the protrusion, and

each of a part of the first sealing layer and a part of the second sealing layer is located between the insulating layer and the moisture-proof member.
