Display device and method for manufacturing the same

A display device comprising:

• an array substrate including:
• a display area having a plurality of pixel areas;
• and
• a light-emitting array including a plurality of light-emitting elements corresponding to the plurality of pixel areas;
• a sealing structure including:
• a first adhesive layer positioned on the array substrate and sealing the light-emitting array;
• a metal barrier layer disposed on the first adhesive layer;
• and
• a second adhesive layer disposed on the metal barrier layer, the first adhesive layer, the metal barrier layer and the second adhesive layer being stacked;
• a protective layer positioned on the second adhesive layer;
• a reinforcing substrate positioned on the protective layer;
• a printed circuit board positioned on the reinforcing substrate;
• and
• a grounding member connecting the printed circuit board to the array substrate,
• wherein the grounding member is in contact with a surface of the metal barrier layer exposed in a trench groove, the trench groove extending through the protective layer and the second adhesive layer.

A display device comprising:

• an array substrate including:
• a transistor array;
• and
• a light-emitting array;
• a sealing structure positioned on the array substrate to seal the light-emitting array, and including a metal barrier layer;
• a protective layer positioned on the sealing structure;
• a printed circuit board overlapping the protective layer;
• and
• a grounding member connected to the printed circuit board, the array substrate and the sealing structure, the grounding member being configured to emit electromagnetic signals to the outside,
• wherein the sealing structure includes a first adhesive layer and a second adhesive layer,
• wherein the first adhesive layer is disposed on a first surface of the metal barrier layer facing the array substrate,
• wherein the second adhesive layer is disposed on a second surface opposite to the first surface of the metal barrier layer, and
• wherein the metal barrier layer is disposed between the first adhesive layer and the second adhesive layer.
