Light emitting decoration, method for laying light emitting decoration, laying object and method for forming light emitting design

A laying object comprising a light emitting decoration laid thereon, the light emitting decoration comprising:

• a woven fabric having a side emission optical fiber woven in a line from one end side to the other end side;
• and
• a light source that introduces light to advance in an advancing direction from the one end side toward the other end side in the optical fiber,
• wherein the woven fabric is laid so that the woven fabric is visually recognized in a state where the other end side of the woven fabric is located on the front side and the one end side is located on the back side,
• wherein when a luminance of the optical fiber observed at a position substantially perpendicular to the light advancing direction is L0, a luminance of the side emission optical fiber observed from a position at an angle of 30 degrees from a line substantially perpendicular to the light advancing direction toward the other end side is L30, a luminance of the side emission optical fiber observed from a position at an angle of 60 degrees from the line substantially perpendicular to the light advancing direction toward the other end side is L60, a luminance of the side emission optical fiber observed from a position at an angle of 60 degrees from the line substantially perpendicular to the light advancing direction toward the one end side is L−60, the optical fiber satisfies L−60<L30 and L30/L0<L60/L30.
