Display device and manufacturing method thereof

A display device comprising

• a display panel which comprises a display area displaying an image and a surrounding area located on an external side relative to the display area and is bent in a belt-like area, wherein
• the display panel comprises:
• a resinous substrate having flexibility;
• a first organic insulating layer provided over the display area and the surrounding area above the resinous substrate;
• a first inorganic insulating layer provided over the display area and the surrounding area on the first organic insulating layer;
• and
• a first partition comprising a first lower portion provided on the first inorganic insulating layer and a first upper portion which is provided on the first lower portion and protrudes from a side surface of the first lower portion in the belt-like area.

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

• forming a circuit layer including a plurality of insulating layers over a display area which displays an image and a surrounding area located on an external side relative to the display area on a resinous substrate having flexibility;
• forming a first organic insulating layer over the display area and the surrounding area on the circuit layer;
• forming a first inorganic insulating layer over the display area and the surrounding area on the first organic insulating layer;
• and
• forming a first partition comprising a first lower portion located on the first inorganic insulating layer and a first upper portion which is located on the first lower portion and protrudes from a side surface of the first lower portion in the surrounding area, wherein
• the circuit layer has a belt-like area in which at least one of the plurality of insulating layers is lost in a belt-like shape, and
• the first partition is located in the belt-like area.
