Display device and manufacturing method of the same

A display device comprising:

• a display panel including a display region;
• and
• an input sensing unit disposed on the display panel,
• wherein the input sensing unit includes a plurality of sensing insulating layers and at least one sensing conductive layer disposed on any one of the plurality of sensing insulating layers, and
• at least one of the plurality of sensing insulating layers has an atomic ratio of nitrogen (N) to silicon (Si) of about 0.69 to about 0.85.

A method of manufacturing a display device, the method comprising:

• forming a first sensing insulating layer on a display panel;
• forming a first sensing conductive layer on the first sensing insulating layer;
• forming a second sensing insulating layer disposed on the first sensing insulating layer and configured to cover the first sensing conductive layer;
• and
• forming a second sensing conductive layer disposed on the second sensing insulating layer,
• wherein the first sensing insulating layer has an atomic ratio of nitrogen (N) to silicon (Si) of about 0.69 to about 0.85.
