Display device and flexible circuit board

A display device, comprising:

• a display structure including:
• a display panel including:
• a display area;
• and
• a non-display area around the display area;
• and
• a touch sensing layer disposed on the display panel and including:
• a first portion overlapping the display area;
• and
• a second portion overlapping the non-display area;
• a window structure disposed on the display structure;
• a bonding layer disposed between the display structure and the window structure;
• and
• a touch flexible circuit board electrically connected with the touch sensing layer, the touch flexible circuit board including:
• a first substrate member connected to the second portion, and
• a second substrate member provided with an ultraviolet transmitting member which transmits ultraviolet light therethrough the touch flexible circuit board emitted from a side of the bonding layer, and the second substrate member extends from the first substrate member in a predetermined direction,
• wherein the second substrate member includes a bending portion extending from the first substrate member and an extension portion extending from the bending portion and disposed under the display structure, and
• the ultraviolet transmitting member is defined at the bending portion.
